Editorial<br />
dear<br />
readers<br />
This has been a busy autumn, with lots of exhibitions and conferences, the<br />
biggest one that I attended being the European Bioplastics Conference with<br />
about 380 bioplastics experts meeting in Berlin.<br />
Packaging is still the largest field of applications, as can be seen from the<br />
huge section ’films, flexibles, bags‘ in this issue. But durable applications are<br />
not far behind. Thus our second editorial focus is on ‘consumer electronics‘.<br />
In the basics section we cover ‘anaerobic digestion‘ or ‘biogasification‘ and<br />
we shed light on the important issue of ‘quantity, quality and comparability<br />
of material properties‘. In order to give true comparability it is essential that<br />
the standards used are clearly stated together with specifications that are<br />
quoted.<br />

And finally we received the promised article on ‘oxo-biodegradable plastics‘.<br />
I think it is remarkable that the author, Professor Scott, clearly states that oxobiodegradable<br />
plastics are not marketed for composting, nor are they designed<br />
for anaerobic digestion or landfill. Oxo-biodegradable plastic addresses the<br />
problem caused by plastic waste which gets accidentally or deliberately into<br />
the open environment - i.e. littering.<br />
As always, this issue also brings you a number of industry news items and<br />
details of new applications. For next year I once again encourage all companies offering<br />
bioplastics products or services to contribute to the magazine with articles, news, or<br />
statements of opinion. On page 45 you will find the editorial calendar with all editorial<br />
focus subjects for 2010, as well as the editorial deadlines.<br />
I hope you enjoy reading this issue of bioplastics MAGAzINE.<br />
Yours<br />

100% Bio-Sourced Thermoplastic Elastomers<br />
News<br />
Capitalizing on its long-standing experience in castor oil<br />
chemistry, France based Arkema has now developed Pebax ®<br />
Rnew100, a range of thermoplastic elastomers produced<br />
entirely from renewable raw materials.<br />
By combining a bio-sourced polyol with castor oil chemistry,<br />
Arkema further extends its program to substitute fossil raw<br />
materials with raw materials of plant origin, in line with<br />
its sustainable development policy. Complementing the<br />
Pebax Rnew range which is based on 20 to 95% plant origin<br />
carbon, Pebax Rnew100, Arkema’s latest high performance<br />
thermoplastic elastomer range, is entirely derived from<br />
renewable resources. Thanks to a reduction in fossil energy<br />
requirements during their production and in overall equivalent<br />
CO 2<br />
emissions, these products will find a natural place within<br />
the eco-design programs initiated by many manufacturers.<br />
As with the other Pebax grades, Pebax Rnew100 boasts<br />
outstanding mechanical properties, together with excellent<br />
resistance to thermal and ultra-violet ageing. Light weight<br />
and outstanding dynamic behavior, hence excellent resistance<br />
to both flexural and tensile stress, also set this product<br />
apart. Pebax Rnew100 therefore offers the best possible<br />
compromise between rigidity and mechanical strength at<br />
cold temperature.<br />
Pebax Rnew and Rnew100 have countless industrial<br />
applications involving the manufacture of high added value<br />
products. They fulfil stringent specification requirements in<br />
many sectors, including automotive, electronics and sports<br />
equipment.<br />

Bio-Based Plastics:<br />
New Study Forecasts<br />
Enormous Potential<br />
New bio-based polymers have been available in the market<br />
for approximately one decade. Recently, standard polymers<br />
like polyethylene, polypropylene, PVC or PET, but also highperformance<br />
polymers like polyamide or polyester have<br />
been totally or partially substituted by their renewable raw<br />
materials equivalents. The starting raw materials are usually<br />
sugars or starches, partially also recycled materials from<br />
food or wood processing.<br />
In a jointly commissioned study, recently published by<br />
the associations European Bioplastics and the European<br />
Polysaccharide Network of Excellence EPNOE, Martin K. Patel,<br />
Li Shen and Juliane Haufe (Utrecht University) demonstrate<br />
that up to 90 % of the current global consumption of polymers<br />
can technically be converted from oil and gas to renewable<br />
raw materials. “Bio-based plastics will not substitute oilbased<br />
polymers in the near future for several reasons<br />
including low oil price, high production cost and restricted<br />
production capacity of biomass-based polymers that limit the<br />
technically possible growth of these plastics in the coming<br />
years“, explains Patrick Navard, Chairman of the Governing<br />
Board of EPNOE.<br />
Based on recent company announcements the production<br />
capacity of bio-based plastics is projected to increase from<br />
360,000 tons in 2007 to about 2.3 million tons by 2013. This<br />
corresponds to an annual growth of 37 %. “We should keep a<br />
close eye on these figures“, says Hasso von Pogrell, Managing<br />
Director of European Bioplastics. “Important major projects<br />
were delayed in the years 2008 and 2009 due to the financial<br />
and economic crisis. Despite the still uncertain data, which of<br />
course has to be further consolidated, we deem such studies<br />
to be very essential. The role that lightweight conventional<br />
plastics played in the past, substituting durable materials<br />
like iron and steel in vast products, could soon be taken over<br />
by bio-based plastics. As the study shows, the potential is<br />
enormous“, adds von Pogrell.<br />
The study discusses for all major groups of bio-based<br />
plastics the production process, the material properties<br />
and the extent to which they could substitute petrochemical<br />
polymers from a technical point of view. Further aspects<br />
covered are the prices of these novel materials and their main<br />
producers. Three scenarios are distinguished to establish<br />
potential future growth trajectories, i.e. a baseline scenario, an<br />
optimistic and a conservative scenario. The results for these<br />
scenarios are also compared to the findings of a previous<br />
study made in 2005. The new study confirms that substantial<br />
technological progress has been made in bio-based plastics<br />
in the past five years. Innovations in material and product<br />
development, environmental benefits as well as the gradual<br />
depletion of crude oil increasingly call for polymers made<br />
from renewable raw materials.<br />

News<br />
Bioplastic<br />
from Algae<br />
California (USA) based Cereplast Inc. recently<br />
announced that it has been developing a breakthrough<br />
technology to transform algae into bioplastics and<br />
intends to launch a new family of algae-based resins<br />
that will complement the company’s existing line of<br />
Compostables ® & Hybrid ® resins.<br />
Cereplast algae-based resins could replace 50%<br />
or more of the petroleum content used in traditional<br />
plastic resins. Currently, Cereplast is using renewable<br />
material such as starches from corn, tapioca, wheat<br />
and potatoes and Ingeo TM PLA.<br />
“Our algae research has shown promising results<br />
and we believe that in the months to come we should<br />
be able to launch this new family of algae-based<br />
resins,” stated Frederic Scheer, Founder, Chairman<br />
and CEO of Cereplast. “Algae-based resins represent<br />
an outstanding opportunity for companies across the<br />
plastic supply chain to become more environmentally<br />
sustainable and reduce the industry‘s reliance on oil.<br />
We are still in the development phase, but we believe<br />
that this breakthrough technology could result in a<br />
significant new line of business in the years to come.”<br />
“Based on our own efforts, as well as recent<br />
commitments by major players in the algae field, we<br />
believe that algae has the potential to become one of<br />
the most important ‘green‘ feedstocks for biofuels, as<br />
well as bioplastics,” continued Mr Scheer. “Clearly, our<br />
focus will be on bioplastics. However, for our algaebased<br />
resins to be successful, we require the production<br />
of substantial quantities of algae feedstock. We are very<br />
encouraged when we see big players entering the algae<br />
production business, including Exxon’s $600 million<br />
investment in Synthetic Genomics and BP’s $10 million<br />
investment in Martek Biosciences.”<br />
Cereplast has initiated contact with several<br />
companies that plan to use algae to minimize the<br />
CO 2<br />
and NO X<br />
gases from polluting smoke-stack<br />
environments. Algae from a typical photo-bioreactor is<br />
harvested daily and may be treated as biomass, which<br />
can be used as biofuel or as a raw material source for<br />
biopolymer feed stock. The company is also in direct<br />
communication with potential chemical conversion<br />
companies that could convert the algae biomass into<br />
viable monomers for further conversion into potential<br />
biopolymers. “Algae as biomass makes sense in that<br />
it helps close the loop on polluting gases and can be a<br />
significant renewable resource,” added Mr. Scheer.<br />
Multilayer Films<br />
Breakthrough for<br />
Food Contact Market<br />
Global sustainable resins supplier Cardia Bioplastics,<br />
headquartered in Mulgrave,VIC, Australia, has announced<br />
a new range of Cardia Biohybrid based films that comply<br />
with the European Commission standard 2002/72 EC for<br />
food contact.<br />
Cardia Bioplastics has lodged new provisional patents<br />
to protect this innovative technology, which expands its<br />
extensive patent portfolio. Cardia Bioplastics Managing<br />
Director Dr Frank Glatz said the multilayer film technology<br />
provides the food industry with excellent clarity, and<br />
mechanical and processing properties.<br />
“This development enables customers to move<br />
confidently into more sustainable packaging solutions<br />
and opens significant new market opportunities for Cardia<br />
Bioplastics, which extend from commodity packaging into<br />
the food packaging industry. The sustainability benefit of<br />
Cardia Biohybrid multilayer film also offers food marketers<br />
packaging solutions with a competitive edge for their<br />
products,“ said Frank Glatz.<br />
Interest from international brands in Cardia Compostable<br />
and Cardia Biohybrid resins has resulted in the company‘s<br />
decision to expand its manufacturing facility in Nanjing,<br />
China. The relocation to a larger site will effectively double<br />
the company‘s manufacturing capacity.<br />
In addition, Cardia Bioplastics has opened a new<br />
Global Application Development Centre at the company‘s<br />
Melbourne, Australia headquarters. This facility focuses<br />
on the application of Cardia Compostable and Cardia<br />
Biohybrid resins to customers‘ specific products.<br />
Frank Glatz said interest in sustainable resins is growing<br />
consistently as international marketers seek a streamlined<br />
path to technologies that meet more demanding<br />
environmental solutions for their packaging and plastics<br />
products. - MT<br />

New Joint Venture<br />
in India<br />
A new bioplastics joint venture will be the first of its kind<br />
in India, where Earthsoul India Private Limited, through its<br />
promoters the Bilimoria family, will hold 60% and the balance<br />
of 40% will be held by the state-owned J&K Agro Industries<br />
Development Corporation Ltd, led by Dr. G. N. Qasba, managing<br />
director.<br />
Earthsoul India have been the pioneers in India since 2002<br />
for 100% compostable and biodegradable packaging materials<br />
made from renewable raw materials such as waste stream<br />
starch. Market leaders in the field of biopolymer products, they<br />
have been associated with Novamont (Italy) for the past 8 years.<br />
J&K Agro Industries Development Corporation Ltd has been<br />
involved in the manufacture of food products, cattle feed, etc<br />
in the state of Jammu and Kashmir. The corporation is also<br />
proactively engaged in the agricultural and irrigation sectors,<br />
as distributors and facilitators in the supply of machinery and<br />
equipment, fertilizers, mulching films for greenhouses etc.<br />
The two organisations are convinced that they have the<br />
necessary synergies to group together in order to foster and<br />
grow the bioplastics industry in India and South East Asia.<br />
Currently the bioplastics industry worldwide has been enjoying<br />
a growth rate of approximately 20% per year.<br />
The joint venture has earmarked an existing manufacturing<br />
facility, owned by J&K, at Sidco Industrial Area, Bari Brahmna,<br />
which is classified as an industrially backward area. The head<br />
office of the joint venture company will be situated at Srinagar.<br />
Equipped with state-of-the-art plant and machinery, both<br />
domestic and imported, the facility will have a capacity of<br />
approximately 50 tonnes per month and will be J&K’s first<br />
carbon neutral manufacturing facility.<br />
The designated executive chairman of the new joint venture,<br />
Perses M. Bilimoria, is a well-known bioplastics personality<br />
in India. He was the first significant introducer of biopolymer<br />
products into India and has been on various committees of the<br />
Ministry of Enviroment and Forests, New Delhi, for plastics<br />
in waste management and on the BIS committee, New Delhi,<br />
for adopting international standards on compostable and<br />
biodegradable raw materials, made from renewable resources.<br />
The company will be managed by a team of professionals<br />
chosen by the board of directors from a wide spectrum of the<br />
manufacturing industry.<br />
The product range of the new company comprises 100%<br />
compostable and biodegradable bags, mulching films for<br />
agriculture, nursery pots and sapling bags for the horticulture<br />
and floriculture markets.<br />
The facility is due to commence trial production in 12/09 and<br />
to enter the commercial market before 03/10. MT<br />

Plastics in the<br />
North Pacific Gyre<br />
Commenting on Project Kaisei‘s findings on<br />
plastics in the North Pacific Gyre, the British<br />
Plastics Federation (BPF) believes that plastics<br />
litter is far too common in the marine environment,<br />
it should not be there and more effort is needed by<br />
all concerned to ensure good waste management<br />
on shore and on vessels, and to provide education<br />
on littering. Furthermore, the Federation wishes to<br />
draw attention to a major initiative it has recently<br />
launched to stop any loss of plastics raw material<br />
into the environment.<br />
The United Nations Environmental programme‘s<br />
report last year pointed to the difficulties in<br />
obtaining accurate information but to tackle the<br />
problem of all waste in the oceans they called for:<br />
integrated waste management to tackle litter; raise<br />
public awareness and education; improved port<br />
waste collection facilities; and stronger economic<br />
incentives, fines, and enforcement.<br />
The BPF supports all these objectives and<br />
recently launched an initiative in the UK called<br />
‘Operation Clean Sweep - Plastic Pellet Loss<br />
Prevention’, to ensure that raw material does not<br />
escape into the environment. The BPF hopes to<br />
get the commitment of every company, from top<br />
management to shop floor employees to use the<br />
Operation Clean Sweep manual on prevention,<br />
containment and clean up of plastic materials to<br />
ensure no escape into the environment.<br />
Peter Davis, BPF Director-General says: “The<br />
Plastics industry does not put plastic into the seas.<br />
This is caused by littering, illegal dumping, poor<br />
waste management. We want the plastic back to be<br />
recycled or provide much needed energy through<br />
energy from waste combustion. International cooperation<br />
is needed to make this work, it is a global<br />
problem.”<br />
Concerning so-called ‘oxo-biodegradable’<br />
plastics the BPF believes that littering is a<br />
behavioural issue and not one related or confined<br />
to the use of specific materials. MT<br />

Field Trial of Bioplastic-Producing<br />
Tobacco Crop Successful<br />
Metabolix, Inc., a bioscience company from Cambridge, Massachusetts,<br />
USA, focused on developing sustainable solutions for plastics, chemicals<br />
and energy, recently announced that it has completed a field trial of<br />
tobacco, genetically engineered to express polyhydroxyalkanoate (PHA)<br />
biobased polymers. Metabolix obtained the necessary permits from the<br />
U.S. Department of Agrculture Animal Plant Health Inspection Service<br />
(APHIS) to perform an open air field trial in March of 2009 and field trial<br />
experiments were completed in early October. The trial was performed on<br />
3,237 m² (0.8 acres) of land and provided valuable data and information<br />
relating to polymer production, with the best plants producing 3-5% PHA.<br />
This furthers development of Metabolix crop technologies for the coproduction<br />
of biobased plastics in non-food bioenergy crops.<br />
Dr. Oliver Peoples, Chief Scientific Officer of Metabolix, commented, “The<br />
experience and knowledge we have gained during our tobacco field trial is<br />
laying the groundwork for planning and permitting activities for field trials<br />
in bioengineered, non-food oilseed and biomass crops producing PHA.<br />
We believe that our crop programs offer a number of commercialization<br />
options and hold significant potential. We are excited to continue to push<br />
this technology forward and believe it will ultimately support a diverse<br />
array of bioengineered, environmentally conscious and economically viable<br />
alternatives to petroleum-based products.“<br />

Another<br />
World-First<br />
The highly innovative technical team at<br />
Ultimate Packaging believes it has produced a<br />
world first environmentally-friendly product as<br />
part of a joint venture with Innovia Films and Sun<br />
Chemical. Staff at the North East Lincolnshirebased<br />
company believe that Ultigreen is the first<br />
ever truly biodegradable and home compostable<br />
printed laminate for the food industry.<br />
Using hybrid biodegradable inks, Ultimate<br />
Packaging has reverse-printed Natureflex<br />
and laminated the material using a unique<br />
biodegradable adhesive to metallised Natureflex.<br />
The company has already established itself as<br />
one of the UK‘s flexographic print suppliers to the<br />
food industry, but the experienced team continue<br />
to focus on finding innovative new solutions for<br />
its customers.<br />
Ultimate Packaging Technical Manager,<br />
Derek Gibson, explains “Until now, only a small<br />
coverage of standard inks could be used to enable<br />
products to pass the EN13432 standard and to be<br />
rated as biodegradable. The new Sun Chemical<br />
hybrid inks allow total print coverage on food<br />
packs and the biodegradable adhesive applied<br />
to bond these two Innovia materials means that<br />
this product can be classed as being made from<br />
totally biodegradable components.<br />
“We selected a promotional tea design to prove<br />
that the newly developed biodegradable inks and<br />
adhesive were compatible and then printed the<br />
Ultigreen product on our recently commissioned<br />
Soma Imperia 10 colour press.“<br />
The new product development team at Ultimate<br />
Packaging is now working on further products<br />
using the new ink and adhesive technology to<br />
bring additional completely biodegradable and<br />
home compostable flexible films to their food<br />
industry customers.<br />
“This really is an exciting development for us<br />
and we believe that it has enormous potential,“<br />
says Chris Tonge, Ultimate Packaging Sales<br />
and Marketing Director. “It is only the first of<br />
several new products that will set our family-run<br />
business apart from our competitors.“<br />

New Eco-Label:<br />
OK biobased<br />
Halfway through the 1990s, Vinçotte developed the OK compost<br />
conformity marks for products meeting the European EN 13432<br />
standard, thereby playing a pioneering role during that period<br />
of time. Thanks to the new OK biobased certification system<br />
manufacturers can officially demonstrate the use of renewable raw<br />
materials via the independent OK biobased conformity marks.<br />
This is the first time an official certification body has launched a<br />
similar conformity mark based on exact measurements. Demand<br />
rose in particular from the packaging industry, as it is constantly on<br />
the look-out for renewable materials, owing to growing pressure<br />
on raw material prices and the way environmental regulations<br />
are being changed all over the world. The buying public‘s growing<br />
awareness of environmental concerns is also ensuring an<br />
expanding market for these products. What is more, consumers<br />
are anxious to have a rock-solid guarantee about the claims found<br />
on packaging. Thanks to the new OK biobased eco-label, Vinçotte<br />
can offer a completely independent guarantee about the origin of<br />
products. In this case, ‘biobased‘ refers to products of a biologically<br />
renewable rather than a fossil origin.<br />
Petroplastics versus bioplastics<br />
The keen interest in bioplastics can be summed up in one<br />
concept: carbon footprint. Biobased products help limit our<br />
carbon footprint, while making us less dependent on fossil<br />
fuels. For several years now a whole host of companies have<br />
been marketing bio-resources partly or entirely on the basis of<br />
biologically renewable carbon.<br />
OK biobased certification: clear and straightforward<br />
Apart from fuels, products (partly) made from bioplastics and/<br />
or materials of natural origin are eligible for the OK biobased<br />
certification mark. The basic material is assessed in the light of<br />
exact analyses for determining the renewable organic carbon<br />
content. The same analysis method (C14) is used for dating bones.<br />
A straightforward calculation can be used to convert the analysis<br />
findings into an exact ‘biobased’ percentage.<br />
As a result of promoting correct and documented claims,<br />
Vinçotte is making a contribution to the harmonized development<br />
of alternative and sustainable technologies.<br />

are, the higher the biobased carbon content: one star means<br />
between 20% and 40% biobased material, two stars between 40%<br />
and 60%, three stars between 60% and 80% and four stars over 80%.<br />

New Record: Bioplastics<br />
Continue On the Road to Success<br />
www.conference.european-bioplastics.org<br />
The European Bioplastics Conference took place for the fourth time in Berlin on the 10th and 11th of November and despite<br />
the difficult financial situation the event broke all records. 380 visitors and 27 exhibitors attended the conference hosted by<br />
the industry association European Bioplastics. Experts still expect continued growth in the field of compostable and biobased<br />
materials.<br />
“Where will the industry be in five years‘ time?“, “What are the trends?“, “Which materials will dominate the market?“,<br />
“How can we communicate the advantages for the environment and what are the optimum utilisation fields for bioplastics?“<br />
28 speakers and 380 participants dealt with these and other questions during the two-day bioplastics conference in Berlin.<br />
Altogether 237 companies from 27 countries attended the event. Approximately 78 % came from Europe, 16 % from Asia and<br />
over 5 % from North and South America.<br />
The European Bioplastics Conference is now in its fourth year and has become an established industry event. “To have broken<br />
attendance records, in spite of the difficult economic background is extremely heartening. Market interest and uptake is very<br />
real and bioplastics producers continue to increase both capacity and the technical capability of their materials“, cheers Andy<br />
Sweetman (left picture above), Chairman of the board of European Bioplastics.<br />
Professor Patel<br />

Conference on<br />
Technical Applications<br />
Biobased materials are today finding a wider usage,<br />
especially for technical (non-packaging) applications. With<br />
this shift from compostable packaging to durable applications<br />
increased demands regarding the material’s performance<br />
and processing properties can be observed. On the subjects<br />
on injection moulding performance, rheological processing<br />
parameters as well as long-term behaviour our knowledge<br />
today is still limited.<br />
Thus these questions and technical applications were the<br />
focus of a conference, ‘bioplastics - technical applications<br />
of biobased materials’, held in Duisburg, Germany in early<br />
October. The conference was chaired by Prof. Hans-Josef<br />
Endres (University of Applied Sciences and Arts, Hanover) and<br />
Prof. Johannes Wortberg (University of Duisburg).<br />
In addition to a general overview of the current situation<br />
experts from raw material suppliers such as DuPont,<br />
Kuraray, Sukano or FKuR informed the conference about<br />
the processing, application and challenges of biopolymers.<br />
Speakers from companies such as KraussMaffei Berstorff,<br />
Huhtamaki, Bosch and Volkswagen discussed the processing<br />
and properties of biopolymers in technical applications.<br />

Deep freezing is a method of preserving foodstuffs containing water.<br />
During deep freezing the storage temperature of the food is<br />
set significantly below freezing point (at least -18 °C), thus slowing<br />
down or even stopping the growth of micro-organisms. Chemical<br />
and physical processes in food are also slowed down or avoided completely.<br />
Biochemical, and most notably enzymatic, reactions are also<br />
slowed down [1].<br />
Requirements of deep-freeze packaging plastics materials<br />
Deep-freeze packaging preserves frozen food from drying-up and<br />
protects it against outside influences: light, air (oxygen), moisture<br />
uptake, contamination and infection by micro-organisms, outside odours<br />
and tastes, as well as mechanical damage. It needs to exhibit barrier<br />
properties and mechanical properties, and also needs to be printable<br />
and weldable.<br />
‘Freezer burn‘<br />
‘Freezer burn‘ is a form of dehydration usually caused by improper<br />
packaging. The surface moisture has evaporated, and the food may<br />
appear lighter in colour and ‘dried out‘. While the food is safe to eat, the<br />
quality is lower. It often has an ‘off-flavour‘.<br />
Whilst at home one can manage to package the goods to be frozen<br />
rather carefully, however the filling process under industrial conditions<br />
looks different: frozen goods - some with sharp edges - may fall from a<br />
belt weigher directly into an open bag, which will then be immediately<br />
closed.<br />
Bio-Flex – bioplastics for deep-freeze packaging.<br />
FKuR´s trade name Bio-Flex ® stands for copolyester blends based<br />
on PLA which – depending on the respective grade – are produced<br />
from a high amount of natural resources. Bio-Flex does not contain<br />
any starch or starch derivatives. The material’s mechanical properties<br />
at low temperatures are particularly crucial for an overall deep-freeze<br />
packaging performance. High impact strength and dart drop strength at<br />

Dettmer Verpackungen (Delo) in Lohne, Germany, uses Bio-Flex<br />
F 2110 as a basis for a multilayer system for deep-freeze packaging.<br />
A packaging film has been developed for the market leader in deep<br />
frozen potato products that meets the many and various requirements.<br />
McCain´s philosophy behind this concept is coherent: ‘100 % Bio – inside<br />
and outside’. McCain´s Bio Harvest products derive from certified,<br />
ecologically controlled cultivation. To emphasize this, packaging<br />
made from renewable resources was needed - which also had to be<br />
biodegradable. The biodegradation, including the inks, has been tested<br />
and certified according to EN 13432. High quality printing with up to<br />
10 colours is possible and the packaging carries the well-established<br />
seedling logo. But, what about the mechanical properties?<br />
Astonishing results were achieved when the biofilm was compared<br />
with polyethylene of the same thickness. Delo, as market leader in<br />
deep-freeze packaging, with 13 blown film units, is known for its highly<br />
demanding performance. Delo coextrudes up to seven layers and prints<br />
on 12 flexo print lines, five of which are equipped with 10 colour decks.<br />
The latest generation of biofilms from Delo´s director of development<br />
contains up to 70 % renewable resources, without any compromise.<br />
Fig. 1 shows clearly that by means of Bio-Flex a leap into new dimensions<br />
of mechanical properties of thin packaging films has been achieved.<br />
There is currently no technical obstacle to a broad market launch.<br />
Delo have even managed to offer solutions that have so far not been<br />
possible with PE. Excellent puncture resistance or rigidity previously<br />
only achievable in multilayer systems, open up completely new scopes<br />
for design. High quality raw materials and compounds such as Bio-<br />
Flex today allow for a broad variety off coextruded films as ‘customized<br />
products‘.<br />

Carbon-Neutral and<br />
Compostable Films -<br />
A Holistic Approach<br />
Sustainability has long been more than just a buzzword at the packaging<br />
film manufacturer alesco from Langerwehe, Germany. The business is<br />
committed to pursuing a holistic approach in this respect – conservation<br />
of resources, environmental protection, carbon neutrality, social responsibility<br />
and environmentally friendly innovation are all factors in this strategy. And<br />
because these issues are a way of life at the company, with its 210 employees,<br />
rather than just being a marketing slogan, the manufacturer of PE and biofilm<br />
packaging is happy to show its cards and be open about its approach in order<br />
to encourage others to follow this responsible path.<br />
“We developed a mission statement and a vision together with our staff in<br />
a number of joint workshops. These provide the basis for our environmental<br />
protection goals, our commitment to development that conserves resources<br />
and also our principle of carbon neutrality,” explains alesco Managing<br />
Director Philipp Depiereux with regard to the emergence of the revamped<br />
corporate philosophy with its focus on sustainability. Depiereux joined the<br />
new management team in 2004 and wanted to do more than merely produce<br />
marketing material focusing on new green products in the company. He wanted<br />
the company to really live and work in a green way on a daily basis.<br />
Not an easy task, as he admits in retrospect: persuading employees that<br />
have worked for decades with products manufactured from the finite resource<br />
that is oil to switch to green and sustainable strategies requires some well<br />
chosen words. However, the results of the drive for holistic sustainability in the<br />
business and in the products are now tangible throughout the company.<br />
For example, in the compostable film produced from sustainable raw<br />
materials. After three years of development work, the first biofilm from alesco<br />
was presented at the special show entitled “Bioplastics in Packaging” at<br />
interpack 2008 in Düsseldorf, and the fruit and vegetable bags proved to be a<br />
real hit at the trade fair.<br />
New areas of application, such as brochure packaging films for direct<br />
mailings and catalogues (e.g. bM 5/2009), compostable shopping bags, deep<br />
freeze films and the new Bioshrink, which was presented at drinktec (Munich,<br />
Germany), show that all the staff at alesco are now right behind this groundbreaking<br />
approach. But alesco has also put a great deal of thought into<br />
issues beyond the actual products themselves; for example, all biofilms are<br />
manufactured exclusively using green electricity produced from hydropower.<br />
And this commitment to green electricity will be extended by alesco to all of its<br />
production facilities in Langerwehe from 2010.<br />
But a holistic approach requires more than environmentally friendly<br />
products alone. alesco pursues its strategy in the production process as well<br />

– such as with the solvent recovery facility in the print shop. This system<br />
allows solvents, which are used in large volumes in the print shop, to<br />
be separated from the paint sludge, after which they are returned to<br />
the production system to be used again. The system led to a reduction<br />
in solvents of 70,000 litres (which therefore did not need to be newly<br />
purchased or expensively disposed of) in 2008 alone - the first year of<br />
operation – and the trend is on an upward trajectory. This means that<br />
important resources are conserved, roads are relieved of traffic due to<br />
reduced freight requirements and CO 2<br />
emissions are also reduced as a<br />
direct consequence of this.<br />
A paint mixing facility was also installed in the print shop in 2008. This<br />
means that alesco now generally only has to order basic colours as it<br />
can mix special colours on-site, and it also means that waste is avoided<br />
as only the required amount of paint has to be mixed. If, for example,<br />
a customer in the consumer goods sector reduces its printing order at<br />
short notice, then already ordered paint does not have to be disposed<br />
of or put into long term storage. In its very first year, this measure led<br />
to a reduction in requirements equating to 40,000 litres of paint, which<br />
would otherwise have had to be transported away and disposed of.<br />
Lotta, our four year old cover girl says:<br />
„Oh, I loved the yummy carrots and<br />
my daddy made the plastic<br />
bags from bioplastics“.<br />
The company has also worked to achieve environmental optimisation<br />
with regard to the actual paints it uses. This is where solvent free,<br />
water-based paints were the solution. The research and development<br />
team worked for quite some time on these in order to achieve exactly<br />
the right composition and, as a result, it has been possible since<br />
2009 to order print runs for compostable biofilms with this even more<br />
environmentally friendly paint. Printing can be carried out on up to<br />
eight printing units and the use of new paints does not necessarily lead<br />
to a compromise with regard to quality; part of a holistic approach also<br />
involves never losing sight of the needs of customers – who like nice,<br />
glossy printed images.<br />
Regranulation avoids unnecessary transportation<br />
At alesco, film regranulation of edge strips and rejects is handled<br />
internally: an in-house film regranulation system and a service<br />
provider based on-site results in short transportation distances for the<br />
reprocessing. This avoids the emissions that would otherwise have been<br />
produced during transportation to a regranulation plant some distance<br />
away. The entire stock of alesco regranulate material is then returned<br />
to the production process and not sold on to other film manufacturers,<br />
which would also result in transportation emissions.<br />
bioplastics MAGAZINE [06/09] Vol. 4 15
A CO 2<br />
footprint makes environmental protection<br />
measurable at alesco<br />
In order to be able to measure the overall positive<br />
environmental effects of the innovative developments<br />
and modernisation in the production process, alesco<br />
commissioned the calculation of a corporate carbon footprint<br />
(CCF) for the entire company and a product carbon footprint<br />
(PCF) for all the packaging film products at the beginning<br />
of 2009. These footprints show how much carbon dioxide is<br />
emitted for each kilogramme of film produced.<br />
However, the environmental efforts of the film manufacturer<br />
cannot be gauged from the first CO 2<br />
footprint as this is a<br />
reference from which to measure progress, so stopping at<br />
that would not fit in with the holistic approach of the company.<br />
“We will only be able to see what we have achieved when<br />
we commission the calculation of a new footprint next year<br />
and can compare the values to see by how much our CO 2<br />
emissions per kilogramme of film produced have decreased,”<br />
adds Depiereux.<br />
Although this may sound very simple, it actually requires<br />
a lot of careful planning: as well as the entire energy<br />
consumption at alesco and relevant data from suppliers<br />
(raw material suppliers, paint suppliers, additive suppliers,<br />
suppliers of solvents and also suppliers of other consumables<br />
etc.), all commuting-related CO 2<br />
emissions generated by the<br />
210 members of staff at alesco were also determined – which<br />
involves taking into account the routes taken as well as the use<br />
of cars, bicycles, trains and buses. The PCF also included the<br />
entire supply chain, the processing stages (film production,<br />
film printing, film packaging) and the subsequent route to<br />
their place of utilisation. The footprints were calculated by an<br />
independent climate protection consultancy - ClimatePartner<br />
Deutschland GmbH. Only the process of packaging products<br />
using the film at the customer and the subsequent use and<br />
recycling by consumers could not be taken into account.<br />
“Unfortunately, we do not know if the consumers arrive at<br />
the point of sale on foot or by vehicle in order to acquire the<br />
packaged product,” explains Alexander Rossner, Managing<br />
Director of ClimatePartner Deutschland GmbH.<br />
Carbon neutral packaging<br />
The CO 2<br />
footprint also provides another benefit: if it is<br />
known how much CO 2<br />
is still produced as a result of the<br />
production process despite the implementation of a range<br />
of measures, the film can at least be produced in a carbon<br />
neutral way by means of acquiring the corresponding amount<br />
of climate protection certificates to enable carbon offsetting.<br />
alesco is one of the first packaging film manufacturers in the<br />
world to offer its customers this service. All alesco biofilms<br />
are already produced and supplied carbon neutrally at no<br />
extra cost. And, if customers wish to acquire other types of<br />
film carbon neutrally, then the only additional charge made is<br />
the actual cost of acquiring the necessary climate protection<br />
certificates.<br />
The number of certificates required is determined using a<br />
climate calculator, which provides alesco with exact emission<br />
figures for the production of each individual type of film. “In<br />
this way, we can offset the emissions in accordance with the<br />
provisions of the Kyoto protocol. For the neutralisation of the<br />
biofilm products, we have chosen an approved and certified<br />
biomass project in India,” comments Depiereux.<br />
alesco has also not forgotten the marketing opportunities<br />
that this approach can provide for customers, who now have<br />
the option with printed films of including information about<br />
the carbon neutrality of the packaging film. And this seems<br />
to be a popular choice: since the certification of the films<br />
was started, numerous orders have been produced carbon<br />
neutrally and a number of customers have chosen to have the<br />
film labelled as being carbon neutral.<br />
There is still a lot of scope for improvement in the<br />
future.<br />
With their holistic approach, the staff at alesco have by<br />
no means exhausted all the potential measures that can be<br />
implemented: hauliers must also consider using trucks with<br />
low fuel consumption figures, and raw material and additive<br />
suppliers can investigate environmentally friendly production<br />
methods. An environmental report is currently being produced<br />
in order to document all alesco’s environmental initiatives and<br />
projects. “The green strategies of conservation of resources,<br />
avoidance of emissions and reduction of emissions will<br />
continue to be pushed, even in tough economic times,” states<br />
Philipp Depiereux as a clear indication of the company’s<br />
steadfast commitment. Rest assured, the alesco staff will<br />
continue to do their utmost to protect the environment.<br />

PLA Films are<br />
a Team Sport<br />
As the supplier base has grown recently, a wide diversity of Ingeo films are being<br />
used in bags, wraps, lids, and labels. Among all the products in the bioplastic<br />
industry, films may best exemplify the supply chain’s team effort through<br />
close engineering cooperation to build innovation into the products delivered to consumers.<br />
For example, French manufacturer Polyfilms, which operates a state-of-the-art<br />
plant for coextruded, bioriented films near Paris, has developed Polybio — a range of<br />
Ingeo-based oriented films. Polybio film is laminated on paper bags for bread or salad<br />
(Fig. 1). It is also used for sealable film lidding and both white and transparent film<br />
labels. Once metalized (either with transparent or white film) the barrier properties are<br />
enhanced and the product has high opacity and brilliance.<br />

www.natureworksllc.com<br />
Polyfilms also sells Polybio to a family of converters that add to the film’s barrier<br />
properties to expand the number of potential applications for this product. Metalvuoto<br />
has developed a lacquer coated oxygen-barrier film under the brand name Oxaqua ® .<br />
One of these converters, Alcan Packaging, offers CERAMIS ® -PLA films which are<br />
transparent high barrier films with a silicon oxide coating.<br />
Goglio Cofibox SpA manufactures a printable laminated film, which Sant’Anna ® uses<br />
for the labels on its bottled water. Fres-co System USA has developed a hybrid solution<br />
for coffee packaging. This development incorporates Ingeo film into a multilayer<br />
structure made with traditional materials. The company says this is Kyoto protocol<br />
ready packaging.<br />
Polyfilms is not the only company producing PLA-based oriented films and working<br />
closely with converters. SKC offers its Skywel ® branded film, and Ingeo licensee<br />
Huhtamaki Films Global has developed a wide range of functional and tailor-made<br />
Ingeo film grades characterized by adjustable mechanical properties for a broad<br />
range of applications, e.g. improved impact resistance and high barrier properties.<br />
Sidaplax/Plastic Suppliers offers a range of clear and white films under the EarthFirst ®<br />
brand name(see page 18)<br />
This industry now goes beyond oriented or blown film developers and value added<br />
converters. Sleever International, for example, has developed an Ingeo heat shrink<br />
film under the Biosleeve ® brand. Sleever International provides its food and cosmetic<br />
packaging customers with colorfully vibrant heat shrink labels. Biosleeve can also be<br />
used for tamper evident bands (Fig. 2).<br />
As these examples show, the bioplastic supply chain has invested in innovation. From<br />
these supply chain efforts, brand owners and consumers can expect an expanding<br />
choice of performance Ingeo films that help to reduce the overall environmental impact<br />
of packaging as compared to petroleum-based films.<br />

PLA Film<br />
Applications<br />
The trend toward using biopolymers and environmentally<br />
friendly films continues to expand into traditional<br />
plastic film applications. The flexible packaging, lamination,<br />
bread bag, windowing (envelope and folding carton),<br />
shrink sleeve label and tamper evident band markets are<br />
some of the many applications that currently incorporate the<br />
use of biopolymer films.<br />
The transition to biopolymer films has been slow.<br />
However, the introduction of EarthFirst ® has allowed for<br />
greater penetration into plastic film markets because of its<br />
environmental and mechanical benefits.<br />
Made from Ingeo PLA, EarthFirst is produced using<br />
annually renewable resources, and is a certified compostable<br />
product under the DIN 13432 and ASTM D6400 standards for<br />
industrial composting.<br />
And it is more than just an environmentally friendly<br />
product. While the environmentally friendly attributes make<br />
it attractive to ‘green’ minded companies, the mechanical<br />
properties allow it to run as well as traditional plastic films<br />
on a wide range of processing equipment. Having a natural<br />
dyne level of 38 makes it suitable for printed applications and<br />
its direct food contact (FDA) compliance has opened the door<br />
to the flexible packaging market.<br />
Shrink sleeve label and tamper evident bands are utilizing<br />
EarthFirst TDO film. Low shrink initiation temperatures<br />
and the ability to shrink up to 75% makes EarthFirst the<br />
ideal shrink film. In addition, EarthFirst shrink sleeve film<br />
can be stored up to 40° celsius offering energy savings that<br />
petrochemical films cannot. Jiffy Pot in Europe is using<br />
EarthFirst as a shrink sleeve label around their plant pots. In<br />
the United States, ConAgra has made the switch from PVC to<br />
EarthFirst for their tamper evident bands around their table<br />
spread product offerings.<br />
Large envelope houses in Europe like GPV, Hamelin and the<br />
Mayer Kuvert Network have adopted the use of EarthFirst for<br />
their envelope window film offerings. The film compliments<br />
their full line of FSC paper based envelope offerings. The<br />
crystal clear look of EarthFirst offers envelope windowing<br />
applications an alternative to the traditional films in the<br />
market today.<br />
Bread bags are another market utilizing the EarthFirst<br />
product. Retailers understand the environmental benefits of<br />
EarthFirst as the high moisture vapor transmission rate of<br />
EarthFirst guarantees that the bread inside remains crispy.<br />
EarthFirst can be found in Delhaize, Carrefour and Auchan<br />
bread bag products.<br />
In many cases EarthFirst even outperforms petrochemical<br />
based films when it comes to printing, sealing and overall<br />
machinability.<br />

Paper cups and shrink<br />
film are the first two<br />
applications for BASF’s<br />
new biodegradable<br />
plastic Ecovio ® FS<br />
High-Performance<br />
and Biodegradable<br />
At the 4th European Bioplastics Conference (see page 10) BASF presented a new biodegradable plastic branded as<br />
Ecovio ® FS. BASF has optimized this new plastic for two specific applications: for coating paper and for manufacturing<br />
so-called shrink films, which serve to easily wrap packaged goods. For this reason, the first two new plastic types are<br />
called Ecovio FS Paper and Ecovio FS Shrink Film. Sample material is already available. Initial production tests at customers’<br />
facilities have been successful. Introduction into the market at large is scheduled for the first quarter of 2010.<br />
Biodegrading even more quickly<br />
As has been demonstrated in recent composting experiments, the new Ecovio FS biodegrades even more rapidly than its<br />
predecessors, and it has a higher content of renewable raw materials. “Ecovio FS consists of the likewise new, now bio-based<br />
Ecoflex ® FS (a biodegradable polyester made by BASF) and of PLA. The use of the new Ecoflex FS raises the proportion of biobased<br />
material in Ecovio FS Shrink Film to 66% and that of Ecovio FS Paper to a full 75%,” explains Jürgen Keck, who heads<br />
BASF’s global business with biodegradable plastics.<br />
Paper cups and packaging film: high-performance counts<br />
The experts who developed the new Ecovio FS focused on the properties that are required of these special applications. “In<br />
order to obtain effective paper coatings, a film made of the new Ecovio FS Paper has to be easy to process and exhibit good<br />
adhesion to the paper, even when applied in thin layers. Such coatings are used, for example, on paper cups or cardboard<br />
boxes,” explains Gabriel Skupin, who is in charge of technical product development for biodegradable plastics. Ecovio FS<br />
Shrink Film, in contrast, has a selected ratio of shrinkage to strength, so that its mechanical load capacity at a film thickness<br />
of merely 25 μm is greater than that of a conventional polyethylene film that is 50 μm thick.<br />
We want to become more specialized<br />
With this new product family, BASF’s experts for biodegradable plastics are further expanding their assortment. The company<br />
is aiming to become more specialized in this realm, so as to meet the requirements of very specific market segments. This<br />
is reflected in the nomenclature, which will comprise three elements. The first stands for the processing technology – in this<br />
case, F for ‚film‘. The second, S, stands for ‚special‘ and indicates that the new bio-based Ecoflex FS is present. The actual<br />
application itself forms the third element of the name such as, for instance, Paper or Shrink Film. “This consistent designation<br />
method, which will be implemented early next year together with the new products, illustrates the broad potential we anticipate<br />
for technically advanced biodegradable products in this market, which has become very diversified,” explains Andreas Künkel,<br />
head of BASF’s market development for new biodegradable plastic products.<br />

related to these polymers derived from RRM (Renewable Raw Materials),<br />
which in the case of Novamont swallows up 10% of its turnover, today<br />
permits the production of a large range of consumer products. These include<br />
food and non-food packaging, hygiene products, bags and sacks, agricultural<br />
tools and food-service ware, all with a positive environmental impact<br />
(End of Life options) and a positive effect on product performance.<br />
An interesting growth rate has been noticed within the area of films and<br />
flexibles, especially multilayer structures.<br />
At the beginning of the 1990‘s Novamont had already started to understand<br />
that the use of compostable biopolymers would be taking a growing market<br />
share in the area of flexibles, as the following article will describe. The latest<br />
expansion of Novamont’s production capacity is also a demonstration of the<br />
steady growth of this market sector.<br />
Environmental Impact<br />
Novamont’s main mission is to offer original solutions both from the<br />
technical and environmental points of view, starting from renewable raw<br />
materials. Mater-Bi is a generation of established biodegradable and<br />
compostable polymers, continuously evolving, containing compostable<br />
polyesters (based on synthetic and renewable monomers), starch and other<br />
renewable resources. They are able to significantly reduce the environmental<br />
impact in terms of energy consumption and greenhouse effect in specific<br />
closed-loop applications (such as food packaging, catering items, mulch<br />
films, bags for kitchen use and garden waste, etc). They perform as traditional<br />
plastics when in use, and completely biodegrade within a composting cycle<br />
through the action of living organisms when they have been engineered to be<br />
biodegradable and compostable.<br />
The technology that stands behind these new materials has evolved<br />
over the years in various steps: the first based purely on the complexing of<br />
starch, and later the continuous improvement of the environmental profile<br />
of Novamont‘s polymers through the increased use of non-food renewable<br />
resources in various steps, the backwards integration into production of<br />
polyesters and their monomers from RRM’s.<br />
Today we find flexible industrial applications in the areas of waste bags and<br />
liners, shopping bags, loop handles, T-shirts, packaging based on single and<br />
multilayer films, either coextruded or laminated, and of course hygiene and<br />
agricultural applications.<br />
Various process technologies are available, for monolayer or multilayer<br />
structures. The latter variant is used in order to combine different substrates<br />
with each other and to obtain very specific and tailored properties. There<br />
are quite different film families available, which offer very specific properties<br />
(such as puncture resistance, oxygen barrier etc) and, when combined,<br />
suddenly open up a completely new application profile. Suitable new<br />

Film Structures,<br />
for Food and Non-Food<br />
technologies, such as extrusion coating and lamination, are fast growing at a<br />
similar pace as that of the new multilayer (coex) films.<br />
Processing<br />
Processing is nowadays no longer subject to critical discussion, as in the<br />
early 90‘s. Today converting these materials may be carried out on standard<br />
extruders, such as LDPE film blowing lines (minimum thickness in the range<br />
of 10-12µm). Productivity, if the line is specifically designed for Mater-Bi,<br />
is similar to that obtained with conventional polyolefines. Other converting<br />
aspects, such as sealing and printing, are also comparable with standard<br />
materials. Recycling is done conventionally by most of the converters.<br />
Their properties are also very much comparable to those of standard<br />
polyolefines, except some very special properties in the area of OTR (oxygen<br />
transmission rate) and WVTR (water vapour transmission rate):<br />
MFR (g/10 min) 3.5 – 7 ASTM D 1338<br />
E Modulus (MPa) 90 - 700 ASTM D 882<br />
Stress at break (MPa) 22 – 36 ASTM D 882<br />
Elongation at break (%) 250 – 600 ASTM D 882<br />
COF 0.1 – 0.6 DIN 53375 A<br />
Haze (%) 26 - 90 ASTM D 1003<br />
WVTR (g·30μm/m2·24h) 200 – 900 ASTM E 96; 38°C 90% RH<br />
OTR (cc·30μm)/(m2·24h·atm) 500 - 2000 ISO 15105-1; 23°C 50% RH<br />
Extrusion Coating and Lamination<br />
Newly developed applications are based on the extrusion coating and<br />
lamination processes.<br />
In this case special grades do offer the same processability as for given<br />
polymers on standard lines, offering excellent adhesion on most of the<br />
substrates (paper, cardboard, biopolymers, tissues etc), high line speed, web<br />
stability and low gauges.<br />
The main applications may be found either in the area of light flexible<br />
packaging, such as food wrapping, industrial bags and sacks, or in rigid<br />
packaging, such as the one based on heavy cardboard for containers,<br />
trays, deep freeze boxes and for foodservice ware such as cups and plates.<br />
The barrier to oils and fats is quite good, average WVTR is in the range of<br />
250 g/m²·24h (23°C, 50% RH)<br />
Coextruded films also offer a good barrier against fats and oil (compared<br />
to polyolefines), with WVTR ranging from 300 – 800 g·30μm/m²·24h and OTR<br />
in the range of 700 – 2.000 cc·30μm/m²·24h (23°C, 50%RH). Special sealing<br />
layers are used, characterised by a ∆T above 50°C, which allow easy running<br />
on most of the packaging lines, whether they be VFFS (Vertical Form Fill Seal)<br />
or flowpack. Specific film grades are available here, with improved toughness,<br />
modified COF (coefficient of friction) or transparency. In addition some unique<br />
‘Home Compostable‘ solutions are available, intended for use in specific<br />
markets in which this property might be specifically requested.<br />
bioplastics MAGAZINE [06/09] Vol. 4 21
Laminated films, as with multilayer compostable and certified<br />
products, were first introduced in the UK. Mater Bi was laminated onto<br />
a cellulose film, achieving a structure which offers a suitable barrier<br />
property, excellent organoleptic and very high mechanical properties in<br />
terms of toughness and tear resistance, which are needed to pack such<br />
‘sharp‘ edged products as müsli flakes. The reverse printed external<br />
cellulose film, which has excellent visual properties, is combined<br />
with a high tenacity Mater-Bi film in order to obtain packaging which<br />
fully covers the mechanical, organoleptic and processing needs of<br />
such products. This is still one of the unique combinations on the<br />
market able to offer compostability under industrial conditions. New<br />
developments are close to being introduced, such as in the case of<br />
coffee packaging.<br />
Beside the applications described above, films dedicated to the<br />
lamination process on various substrates offering selective barrier/<br />
transmission properties, such as a high water vapour transmission<br />
rate, have found interest amongst producers of hygiene products such<br />
as diapers, overalls etc. Specific requirements are based on a soft,<br />
noiseless and highly breathable material. Recent developments, with<br />
films blown in the range of 10µm, are laminated onto cellulose, viscose<br />
and other non-woven substrates. The main applications may be found<br />
in bed linen, mattress covers and overalls used in clean rooms.<br />
Depending on the application, these converting techniques provide<br />
a very efficient and versatile way to build specific, tailor-made,<br />
multilayer structures.<br />
Flexible Applications<br />
Flexible applications, such as organic waste bags, find their logical<br />
EOL (End of Life) option in the waste stream meant for perishable<br />
waste, such as kitchen and food waste. This application has been in<br />
use for many years and is well implemented amongst thousands of<br />
communities spread all over the world. The environmental advantage<br />
of such application has been well demonstrated.<br />
Other sectors have been identified, in which compostability offers<br />
a unique property, such as in the case of highly contaminated food<br />
packaging, where standard recycling loops cannot be used and<br />
compostability offers the solution to maximize material recovery.<br />
Examples may be found in the area of food processing streams,<br />
characterized by a high level of food waste and very short shelf life<br />
products. Furthermore compostability might offer advantageous<br />
solutions in the case of date-expired packaged food, highly<br />
contaminated kitchen waste, as in fast food restaurants, canteens<br />
and schools.<br />
It is becoming increasingly evident that compostable polymers are<br />
finding their industrial use in ‘virtuous waste systems‘, like some of<br />
those described above. Very high technical performance standards<br />
have been reached, which allow these polymers to be used in very<br />
demanding applications, in the food as well as the non-food area.<br />
The performance of these flexible applications, combined with the<br />
renewable content and its compostability, are the criteria that define<br />
the environmental benefit of such products.<br />

Bioplastic Films<br />
from the Netherlands<br />
Responding to the increase in the demand for biodegradable<br />
and compostable films and packaging<br />
Oerlemans Plastics bv, a packaging producer from<br />
Genderen (the Netherlands), is cooperating with FKuR in Germany<br />
in order to better serve the upcoming organic market.<br />
BI-OPL is the brand name for a wide range of biodegradable<br />
and compostable products such as shoppers, bags, films<br />
and sheets. All products are certified according to EN 13432,<br />
NF AFNOR 52001 (France), OK Compost, Ecocert and OF&G<br />
(Organic Farmers & Growers, UK).<br />
All biodegradable and compostable products are based<br />
on special blends of Ecoflex (a co-polyester by BASF) and<br />
Ingeo PLA by NatureWorks. A big advantage compared to<br />
starch is that the PLA blends have a higher water resistance.<br />
This can be very important in more humid applications such<br />
as anti-weed film for horticultural use. Also this indicates<br />
the possibility of using thinner PLA based films compared to<br />
starch based films.<br />
A correct material thickness helps to create a product that<br />
will degrade more slowly or faster according to the application.<br />
BI-OPL is available in thicknesses from 12 to 120 µm. Widths<br />
can be between 10 cm and 205 cm as plain film, and folded<br />
up to 6 metres.<br />
Shoppers, bags, sheets and films<br />
Oerlemans Plastics can produce shopper bags from single<br />
BI-OPL material without a reinforcement inlay or with double<br />
folded topside so that the shoppers are 100 % made from<br />
compostable materials. Bags and sheets, based on BI-OPL<br />
materials, for many different applications can be produced<br />
according to customers‘ demands and can be printed in up to<br />
8 colours. Films for use on shrink and wrapping machines, or<br />
for manual use, are available in many different sizes.<br />
Horticultural films<br />
The fastest growing market in food production is the organic<br />
food market. Especially for this market Oerlemans Plastics<br />
bv developed a large variety of films to help the growers of<br />
organic food. As anti-weed film the BI-OPL is already used<br />
on many different crops throughout the world. Vegetables<br />
and fruits such as pineapples, fennel, strawberry, zucchini,<br />
pickles, onions and also nursery products and cut flowers are<br />
cultivated with the help of BI-OPL. All of these films can be<br />
produced as unfolded film between 10 cm and 205 cm. A<br />
new feature is the possibility to produce pre-perforated plant<br />
holes in these films.<br />
Plant permeable films<br />
Right now Oerlemans Plastics is preparing the introduction<br />
of a type of BI-OPL film which is ‘plant permeable‘. This means<br />
that certain types of plants, like white and green asparagus,<br />
can be covered with this film and due to the properties of the<br />
film the plant can grow through it. It is expected that these<br />
new types will contribute to a better and easier way to grow<br />
vegetables and fruit for organic growers.<br />
Renewable sources<br />
The different types of raw materials used for the production<br />
of biodegradable and compostable products are partly based<br />
on renewable sources. In the future the percentage of<br />
renewable materials will increase significantly. MT<br />

Biomassbased<br />
Bathroom<br />
Scale<br />
Unitika Ltd. of Osaka, Japan, has successfully developed a new blend of biomass-based<br />
resin, which has unprecedented properties such as mouldability, heat resistance, durability<br />
and impact resistance. Unitika’s techniques for improving polylactic acid (PLA) and<br />
their accumulated knowledge of producing engineering plastic blends have brought this latest<br />
development to a successful conclusion. The new PLA blend, known as TERRAMAC ® resin, offers<br />
impact properties comparable to those of ABS.<br />
Tanita is a world leader in precision electronic scales. With an almost 50% share of the domestic<br />
market the name of Tanita is now a household word in Japan. Tanita recently introduced their<br />
second generation of ‘green’ products with the HS-302 Solar Digital Scale. This environmentally<br />
conscious scale has built-in solar cells that draw power from sunlight or from ordinary household<br />
light, eliminating the need to buy or recharge batteries, as well as saving landfill sites from<br />
additional battery contamination. The new eco-friendly bathroom scale, nicknamed ECO Living,<br />
is equipped with a chassis made from the new Terramac resin, which contributes to about a 20%<br />
reduction in CO 2<br />
emission for the product compared with the previous model. Tanita has started<br />
selling this new bathroom scale mainly in Europe, where the population is relatively ecologicallyminded,<br />
and plans to expand the sales area step by step.<br />
Technological background of Unitika<br />
In order to improve the properties of PLA, Unitika developed a world-first commercially<br />
available heat resistant PLA sheet in October 2002. After that, the shortcomings with regard to<br />
heat resistance, flame retardation, and impact resistance of PLA resins for injection moulding<br />
and foam were overcome by applying Unitika’s nanotechnology, plant-based reinforcements,<br />
inorganic fillers, etc. Unitika’s PLA-based durable Terramac resins have been used in<br />
commercially available cell phones, dishwasher-proof lacquered bowls, digital printers, copying<br />
machines, and more. These ground-breaking resins have driven the expansion of the PLA<br />
market. The new Terramac alloy type can also be used for high mechanical load conditions.<br />
Unitika’s new Terramac alloy, as used in Tanita’s new bathroom scale, has the following<br />
features:<br />
• heat resistance, durability, impact resistance, and processability equal to or surpassing ABS<br />
• about 20% less emission of CO 2<br />
than ABS<br />
• suitable for many of the same applications as ABS<br />
• compliance with ‘BiomassPla’, which means biomass-based plastics, certified by Japan<br />

Eco-Centric<br />
Mobile Phone<br />
The North American telephone company Sprint Nextel, headquartered in Overland<br />
Park, Kansas, USA is making it easier than ever for customers to ‘go green‘ with<br />
new eco-friendly products, services and programs and expanding its commitment<br />
as a leader in sustainability. Last August, Sprint and Samsung Telecommunications<br />
America (Samsung Mobile) announced Samsung Reclaim as the first phone<br />
in the U.S. constructed from eco-centric bio-plastic materials. Made from 80 %<br />
recyclable materials, Samsung Reclaim is a feature-rich messaging phone that<br />
offers environmentally conscious customers a perfect blend of responsibility<br />
without sacrificing the latest in network speeds and must-have features.<br />
When customers purchase Samsung Reclaim from Sprint, $2 of the proceeds<br />
will benefit the Nature Conservancy‘s Adopt an Acre program, which supports<br />
land conservation across the United States and protects some of the world‘s most<br />
beautiful and important natural habitats.<br />
“Sprint is proud of our leadership with environmentally-responsible initiatives,“<br />
said Dan Hesse, Sprint CEO, “and Samsung Reclaim enables customers to go green<br />
without sacrificing the latest in wireless technology.“<br />
Up 40 % of the Reclaim’s outer casing is made of a blend of PLA (40%), a bioplastic<br />
material, made from renewable resources (corn) and Polycarbonate (60%).<br />
This material is mostly used on the rear side and battery cover of the device.<br />
Samsung Reclaim is free of polyvinyl chloride (PVC) and phthalates, and nearly<br />
free of brominated flame retardants (BFR) three materials commonly targeted on<br />
green electronics guidelines.<br />
The outer packaging and the phone tray inside the box are made from 70 %<br />
recycled materials, printed with soy-based ink. The typical thick paper user manual<br />
has been replaced with a virtual manual that users can access online. The Energy<br />
Star approved charger. It consumes 12 times less power than the Energy Star<br />
standard for standby power consumption.<br />
”Samsung Reclaim is more than just an eco-centric device, its also a powerful<br />
and stylish phone that’s easy-to-use,” said Omar Khan, senior vice president of<br />
Strategy and Product Management for Samsung Mobile. “When you combine the<br />
Reclaim’s impressive feature set with its bio-plastic hardware and eco-centric<br />
packaging, you’re using a phone that is good for you and the environment.”<br />
Reclaim has been available from August 16, 2009 in all Sprint retail channels,<br />
including Best Buy, Radio Shack, internet and telesales. It‘s also available at Wal-<br />
Mart since early September.<br />
Reclaim is Samsung’s latest contribution toward its commitment to the<br />
environment. Samsung Electronics Co. was recently named as the second highest<br />
rated company in Greenpeace International’s Guide to Greener Electronics<br />
scorecard. MT<br />

New ‘Eco.‘<br />
Cordless<br />
Telephone<br />
Vacuum<br />
Cleaner<br />
Housing<br />
The latest innovation for Ingeo bioplastic is Telecom<br />
Italia’s environmentally friendly ‘Eco.‘ cordless telephone.<br />
NatureWorks PLA material forms the exterior<br />
shell of the new cordless which matches high technical<br />
performance with sustainability and energy savings. Eco.’s<br />
advanced features include backlight display, handsfree, an<br />
integrated backlight keypad and polyphonic ringtones. This<br />
cordless is also projected to minimize energy consumption.<br />
Telecom Italia’s Eco. cordless has been designed and made<br />
real with the cooperation of Telecom Italia Lab, the University<br />
of Palermo and the MID design studio. In addition to providing<br />
certified environmental credentials, Ingeo provides a naturebased<br />
innovation which enhances the Eco.’s performance<br />
and aesthetics.<br />
This initiative can be marked among those that will surely<br />
improve energy efficiency. As an example, NatureWorks<br />
notes that for 30.000 cordless units, the savings which result<br />
from replacing conventional oil based material with Ingeo<br />
bioplastic, are equivalent to 36 barrels of oil, a full month<br />
of electrical energy for 108 European citizens or driving the<br />
average car 75.000 km.<br />
In addition to its low carbon footprint benefits, Ingeo<br />
biopolymer offers more disposal options than conventional<br />
oil-based plastics, such as composting in controlled industrial<br />
systems when available locally, feedstock recovery which<br />
enables reuse in all end products and markets as well as<br />
matching conventional incineration or landfill routes where<br />
they are appropriate. MT<br />
In early 2009 the Dutch company Philips started to<br />
use a durable PLA-based polymer for the housing<br />
of the Performer EnergyCare FC9178 vacuum<br />
cleaner. And even the packaging consists of about<br />
90% recycled material.<br />
Durable bioplastics applications in Europe became<br />
possible with a specially developed ’Nanoalloy’<br />
technology from the Japanese Toray Industries.<br />
“Conventional PLA-based polymers were not<br />
suitable for the manufacturing process because of<br />
their physical properties and mouldability,“ said a<br />
spokesperson from Toray Industries. Toray were<br />
able to solve the challenge with ‘Ecodear’, a specially<br />
developed bioplastic material. Thus it was possible<br />
to meet the technical demands of the application -<br />
namely heat resistance, impact strength, durability,<br />
mouldabilty and shrinkage factors equivalent to<br />
the standard materials which are currently used in<br />
the market. Finally this led to the first adoption in a<br />
consumer electronics application in Europe.<br />
With this new generation of bio durable bioplastics<br />
Toray has taken an important step into the future for the<br />
next generation of developments for environmentally<br />
friendly products. MT<br />

Oxobiodegradable Plastic<br />
Article contributed by<br />
Professor Gerald Scott DSc,<br />
FRSC, C.Chem, FIMMM<br />
Professor Emeritus<br />
in Chemistry and Polymer Science<br />
of Aston University UK<br />
Chairman of the<br />
British Standards Institute Committee<br />

Chairman of the<br />
Scientific Advisory Board of the<br />
Oxo-biodegradable Plastics<br />
Association.<br />
I<br />
have been asked by Symphony Environmental Technologies (UK) to respond<br />
to a request from Bioplastics Magazine for an article about their d2w Controlled-life<br />
plastics, which degrade by a process of oxo-biodegradation 1 . My<br />
views are based on the research carried out in my own and in many other laboratories<br />
throughout the world since my original patent was filed in 1971, and on my<br />
review of independent test reports carried out on d2w products.<br />
Let us be clear at the outset that oxo-biodegradable plastic is not normally<br />
marketed for composting, and it is not designed for anaerobic digestion nor for<br />
degradation deep in landfill. Let us also be clear that oxo-biodegradable plastic is<br />
not designed to merely fragment – it is designed to be completely bioassimilated<br />
by naturally-occurring micro-organisms in a timescale longer than that required<br />
for composting (180 days) but shorter than for nature’s wastes such as leaves<br />
and twigs (10 years or more), and much shorter than for normal plastics (many<br />
decades). All plastics will eventually become embrittled, and will fragment and<br />
be bioassimilated, but the difference made by oxo-biodegradable technology is<br />
that the process is accelerated.<br />
Oxo-biodegradable plastic is intended to address the environmental problem<br />
caused by plastic waste which gets accidentally or deliberately into the open<br />
environment. This is a well known problem in all countries, and cannot be<br />
ignored by calling it a behavioural issue. Oxo-biodegradable plastic is designed<br />
to harmlessly degrade then biodegrade in the presence of oxygen and to return<br />
the carbon in the plastic to the natural biological cycle. Accordingly, tests in<br />
anaerobic conditions or in composting conditions are not appropriate<br />
Industrial composting is not the same as biodegradation in the environment,<br />
as it is a process operated according to a much shorter timescale than the<br />
processes of nature. EN13432 (and similar composting standards such as ISO<br />
17088, ASTM D6400, ASTM D6868, and Australian 4736-2006) are not relevant to<br />
oxo-biodegradable plastic. Indeed EN13432 itself says that is not appropriate<br />
for plastic waste which may end up in the environment through uncontrolled<br />
means.<br />
Oxo-biodegradable plastic products are normally tested according to ASTM<br />
D6954-04 ‘Standard Guide for Exposing and Testing Plastics that Degrade in the<br />
Environment by a Combination of Oxidation and Biodegradation’. There are two<br />
types of Standards – Standard Guides and Standard Specifications ASTM 6954 is<br />
an acknowledged and respected Standard Guide for performing laboratory tests<br />
on oxo-biodegradable plastic. It has been developed and published by ASTM<br />
International – the American standards organisation – and the second Tier is<br />
directed specifically to proving biodegradation.<br />
Tests performed according to ASTM D6954-04 tell industry and consumers<br />
what they need to know – namely whether the plastic is (a) degradable<br />
(b) biodegradable and (c) non phyto-toxic. It is not necessary to refer to a<br />
Standard Specification unless it is desired to use the material for a particular<br />
purpose such as composting, and ASTM D6954-04 provides that if composting is<br />
the designated disposal route, ASTM D6400 should be used.<br />
ASTM D6954-04 not only provides detailed test methods but it also provides<br />
pass/fail criteria. The oxobiodegradable plastics most commonly used consist of<br />
28 bioplastics MAGAZINE [06/09] Vol. 4
Materials<br />
single polymers to which section 6.6.1 applies. This section requires that 60<br />
% of the organic carbon must be converted to carbon dioxide. Therefore if the<br />
material does not achieve 60% mineralisation the test cannot be completed<br />
and the material cannot be certified.<br />
Having achieved 60% mineralisation, the Note to 6.6.1 provides that testing<br />
may be continued to better determine the length of time the materials will take<br />
to biodegrade. It is not however necessary to continue the test until 100% has<br />
been achieved, because it is possible, by applying the Arrhenius relationship 2<br />
to the test results, to predict the time at which that is likely to occur.<br />
There is no requirement in ASTM D6954-04 for the plastic to be converted to<br />
C0 2<br />
in 180 days because, while timescale is critical for a commercial composting<br />
process, it is not critical for biodegradation in the environment. Timescale in<br />
the natural environment depends on the amount of heat, light, and stress to<br />
which the material is subjected, and as indicated above, nature’s wastes such<br />
as leaves twigs and straw may take ten years or more to biodegrade.<br />
The requirement in EN13432, ASTM D6400 and similar standards for 90%<br />
conversion to CO 2<br />
gas within 180 days is not useful even for composting,<br />
because it contributes to climate change instead of contributing to the fertility<br />
of the soil. ‘Compostable’ plastic, 90% of which has been converted to CO 2<br />
gas, is virtually useless in compost, and nature‘s lignocellulosic wastes do not<br />
behave in this way.<br />
The applications for which oxo-biodegradable plastics are normally used can<br />
vary from very short-life products such as bread-wrappers intended to last a<br />
few months, to durable shopping bags intended to last five years or more. The<br />
conditions under which they are likely to be discarded can also vary from cold<br />
and wet conditions to hot and dry desert conditions. It is for the companies<br />
producing or using these products to evaluate the test results to judge the<br />
suitability of the tested material for those applications and conditions, and to<br />
market them accordingly.<br />
The pro-oxidant additives which cause accelerated degradation are usually<br />
compounds of iron, nickel, cobalt, or manganese together with carefullyformulated<br />
stabilisers, and are added to conventional plastics at the extrusion<br />
stage. These reduce the molecular weight of the material – causing it to be<br />
ultimately consumed by bacteria and fungi. Symphony’s d2w additives have<br />
been tested and proved not to be phyto-toxic, and they do not contain ‘heavy<br />
metals’.<br />
Oxo-biodegradable technology is commonly used for Polyethylene and<br />
Polypropylene products, but it can also be used for Polystyrene. Experiments<br />
are continuing with PET but I am not as yet satisfied that the technology will<br />
work satisfactorily with PET. Experiments are also continuing with PVC.<br />
Tests on oxo-biodegradable plastic products are usually conducted by<br />
independent laboratories such as Smithers-RAPRA (US/UK), Pyxis (UK),<br />
Applus (Spain), etc, according to the test methods prescribed by ASTM D6954-<br />
04. Conditions in the laboratory are designed to simulate so far as possible<br />
conditions in the real world, but have to be accelerated in order that tests may<br />
be done in a reasonable time. Pre-treatment does not invalidate the results.<br />

In the real world the temperature of the soil varies between 0 and<br />
50°C depending on the location. The rate of molar-mass reduction<br />
and biodegradation can be extrapolated for any soil temperature by<br />
means of the Arrhenius relationship 3 .<br />
I have read many independent laboratory test reports on oxobiodegradable<br />
materials supplied by Symphony and by other<br />
manufacturers, which are entirely consistent with the published<br />
scientific literature 4 and with my own research. These manufacturers<br />
are not surprisingly unwilling to disclose their data to their<br />
competitors, but having seen the reports I am satisfied that if properly<br />
manufactured, oxo-biodegradable products will totally biodegrade in<br />
the presence of oxygen.<br />
I am aware of suggestions that fragments of plastic (whether oxobiodegradable,<br />
compostable, or normal plastic) attract toxins in a<br />
marine environment and are ingested by marine creatures. I am not<br />
however persuaded that fragments of plastic are any more likely to<br />
attract toxins than fragments of dead seaweed or any of the other<br />
trillions of fragments which are always present in the sea.<br />
I regard it as a positive factor that oxo-biodegradable plastics are<br />
made from naphtha - a by-product of oil, which used to be wasted.<br />
For so long as the world needs petroleum fuels and lubricants for<br />
engines it makes good environmental sense to use this by-product.<br />
I agree with the June 2009 report from Germany’s Institute for<br />
Energy and Environmental Research, which concluded that oil-based<br />
plastics, especially if recycled, have a better Life-cycle Analysis than<br />
compostable plastics. They added that “The current bags made from<br />
bioplastics have less favourable environmental impact profiles than<br />
the other materials examined” and that this is due to the process<br />
of raw-material production.” (see eg. www.bioplasticsmagazine.<br />
com/20<strong>0906</strong>/1.pdf).<br />
Compostable plastics are designed to be deliberately destroyed in<br />
the composting process, but oxobiodegradable plastics can be reused<br />
many times and can be recycled if collected during their useful<br />
lifespan, which in the case of shopper-bags is about 18 months.<br />
Plastics of any kind should not be used for home-composting as they<br />
are often contaminated with meat and fish residues and temperatures<br />
may not rise high enough to kill the pathogens.<br />

It is not desirable to send otherwise recoverable plastic to landfill,<br />
as plastic is a valuable resource. Nor is it desirable for anything<br />
to degrade in landfill unless the landfill is designed to collect the<br />
resulting gases, which most are not. However if oxo-biodegradables<br />
do end up in landfill, they are designed to disintegrate and partially<br />
biodegrade at or near the surface. Any particles deep in anaerobic<br />
landfill are minimal, and will remain inert indefinitely. They can never<br />
emit methane – unlike compostable plastics, paper, etc.<br />
So far as recycling is concerned, oxo-biodegradable plastic<br />
can be recycled in the same way as ordinary plastic (see www.<br />
bioplasticsmagazine.com/20<strong>0906</strong>). By contrast, ‘compostable’ plastic<br />
cannot be recycled with ordinary plastic, and will ruin the recycling<br />
process if it gets into the waste stream.<br />

Green Nordic Walking –<br />
with Biobased Polyamide<br />
www.esb-sport.de<br />
www.mpp-austria.at<br />
www.dupont.com<br />
The first commercial, injection-molded use of renewablysourced<br />
DuPont Zytel ® RS polyamide in Europe is for the<br />
hand grip, tip, cap and inter-locking elements of the new ‘Exel<br />
NW ECO Trainer’ Nordic walking stick from EXEL Sports Brands<br />
(ESB), Stephanskirchen, Germany. The unreinforced polyamide 610<br />
is produced using sebacic acid extracted from castor oil plants. The<br />
renewably-sourced content of unreinforced Zytel RS is 58 % by wt.<br />
This was a crucial factor in the sports equipment manufacturer decision<br />
to not only base its production in Europe, but to also launch<br />
its own competence model made in the material.<br />
“Both sustainability and the responsible handling of resources are<br />
strongly encouraged within our company. This includes the use of<br />
products with a reduced environmental footprint products offering<br />
the best levels of performance based on high quality standards.<br />
Accordingly, innovative products developments, such as Zytel<br />
RS from DuPont, fit perfectly into our corporate strategy,” states<br />
Richard Holzner, product manager at ESB for the Exel walking<br />
sticks. “All the components are solvent- and toxin-free. Thus, we<br />
are able to guarantee that our customers receive environmentallyfriendly<br />
products offering the best performance according to<br />
European quality standards.”<br />
For the hand grip, a cork or wooden shell can be used on top of<br />
the Zytel RS, enhancing its feel for the user. Carbide is overmolded<br />
with Zytel RS for the tip. Beyond its very good surface finish, the<br />
long chain polyamide 610 offers excellent chemical resistance, low<br />
moisture absorption and temperature resistance between -40°C<br />
and 50° C. The parts were designed and manufactured by Metall<br />
und Plastikwaren Putz GmbH (MPP) of Abtenau in Austria. “The<br />
processability of unreinforced Zytel RS is similar to that of polyamide<br />
66. The material is also easy to color,” reports Georg Putz, managing<br />
director of MPP. “The only differences were an approximately<br />
40°C lower melt temperature and minor variations in shrinkage<br />
behavior. The technical support provided by the polymer distributor<br />
Biesterfeld-Interowa was very helpful during the transition.”<br />
Following its launch at the relevant sporting goods trade shows<br />
such as the ispo winter 2010, the ‘Exel NW ECO Trainer’ will be<br />
available to consumers from specialist sports shops from spring<br />
2010.<br />
The DuPont portfolio of engineering polymers includes a series of<br />
products based on renewable resources. They are either entirely or<br />
partially produced using agriculturally-sourced raw materials such<br />
as corn or castor-oil beans instead of crude oil, thereby helping<br />
reduce the industry’s dependence on increasingly limited crude oil<br />
reserves. - MT<br />

A Magic Powder<br />
in a PLA Powderette<br />
by Rainer<br />
Bittermann,<br />
IFA-Tulln<br />
www.blue-elph.com<br />
www.ifa-tulln.ac.at<br />
In Austria a new product was launched in October based on an aromatic powder which puts the consumer<br />
in a state of ‘relaxed alertness’, according to Rouven Haas the inventor of Blue Elph ® . It is an<br />
absolutely new and innovative edible leisure product - just unwrap the Powderette, tap the capsule,<br />
and suck in the powder - but whatever does it have to do with bioplastics? OK, the powder consists exclusively<br />
of harmless, edible substances and the capsule is made of gelatine, but the Powderette is made<br />
from NatureWorks PLA and additives from Sukano and Polyone.<br />
The development started in 2005 together with the Institute of Natural Materials Technology at the<br />
University Research Institute at Tulln (IFA-Tulln) in Austria. After screening various bioplastics for injection<br />
moulding, PLA was selected because of its high transparency and excellent mechanical properties. The<br />
product design and recipe development took a long time but ended with a perfect shape and excellent<br />
processability.<br />
During the project the properties of PLA in the injection moulding process were investigated. The high<br />
flowability, transparency and rigidity allowed the adoption of a special design that could not be easily<br />
realised using standard polymers. The high variation in wall thickness and the sharp point necessary for<br />
piercing the powder-filled capsule should also be noted here. Thanks to different additives the ejection<br />
and constant colour at a constant transparency level could also be achieved in the end. The next step will<br />
be the construction of a 32-cavity tool to reach the planned output (300,000 for the next 6 months).<br />
For the launch and rapid penetration into the market over 600 people – including press, partners, friends<br />
and celebrities - were invited to the launch party in the ‘Skykitchen‘ club, up above the rooftops of Vienna,<br />
to experience the world of Blue Elph.<br />
The novelty of Blue Elph is not so much its effect as the way of ingesting it, and the associated benefits.<br />
The powder in the capsule is sucked into the mouth using the patented Powderette and acts directly over<br />
the oral mucosa. Caffeine and guarana immediately awaken and sharpen the senses, L-Phenylalanin has<br />
the effect of lifting the mood and passion flower is relaxing. Because of the absorption of Blue Elph via<br />
the oral mucosa the active substances enter the body faster and more directly. The concentration of these<br />
substances is up to 10 times lower than in products that can be drunk or eaten, and so are harmless to<br />
the body.<br />
The inventor Rouven Haas first had the idea for the product eleven years ago. At that time he asked<br />
himself why he didn‘t stop smoking. To cut out such a habit without finding a substitute is very hard, and<br />
with smoking in particular a very personal need is satisfied. This was the moment of birth. He wanted to<br />
create a harmless substitute that combines the fascination and feel of a cigarette with a stimulating effect<br />
as well as an extraordinary taste.<br />

Green Cups in the Skies over Asia<br />
High technology lies behind a seemingly simple innovation led by All Nippon Airways (ANA), which<br />
aims to be the number one airline group in Asia and also to be a leader of environmental action in<br />
the aviation industry. ANA’s passengers will now enjoy their drinks in an Ingeo natural plastic cup.<br />
The cup was planned and developed jointly by NatureWorks and ANA for ANA’s fourth environmental<br />
flights campaign, ‘e-flight‘, which went from October 1 - 31, 2009.<br />
The drinking cups consist of NatureWorks’ Ingeo PLA. ANA held its first ‘e-flight‘ campaign in 2006.<br />
Under the catchphrase “Think about the earth and human beings”, the fourth ‘e-flight‘ promotes<br />
these public awareness initiatives that feature eco-friendly services and products like the PLA cup in<br />
addition to other steps, which include wine in PET bottles and an optional passenger carbon offset<br />
program. The programs will enable ANA to realize its environmental goals both on the ground and<br />
in flight.<br />
Plans call for the Ingeo natural plastic cup to be used on all the domestic flights in Japan and for<br />
coach class passengers on the Narita-Singapore route as a part of ‘e-flight‘ programs.<br />
ANA group is an innovator in environmental action. The company has set targets to significantly<br />
reduce greenhouse gas emissions by the end of 2011 with its domestic flights<br />
in Japan, and has been saving fuel during the flights to achieve this corporate<br />
goal. In addition, ANA is deeply involved in a number of forest and marine<br />
environment restoration projects. As a result of these activities, ANA was the<br />
first company in the aviation industry to be certified as an ‘Eco-First Company‘<br />
by the Japanese Ministry of the Environment.<br />
“The new ANA Ingeo plastic drinking cups will give airline passengers<br />
the opportunity to hold a product symbolic of greater sustainability through<br />
innovative thinking and technology,” said Marc Verbruggen, president and<br />
CEO, NatureWorks LLC. “We are proud to have Ingeo playing a role in the<br />
ANA e-flight program.”<br />
BP Consulting, Japan, headed by President Takeyuki Yamamatsu, an<br />
unwavering advocate for sustainability and sustainable products, also worked<br />
closely with both ANA and NatureWorks to develop, produce, and implement<br />
the Ingeo plastic cups concept. - MT<br />

‘Organic Plug’<br />
made from Bio PA<br />
The fischer group of companies of Waldachtal, Germany<br />
recently presented its first prototype of an<br />
‘organic plug’. The material of the fischer Universal<br />
Plug UX consists of polyamide by DuPont which is mainly<br />
made of renewable substances.<br />
UX with staying power<br />
The fischer UX Universal Plug made of conventional<br />
nylon has been established in the market for many years,<br />
giving users the feeling of reliability and safety. With every<br />
turn of the screw, the plug tightens more and more – until<br />
it is safely expanded inside the drill hole or knotted inside<br />
the cavity. A true all-rounder, the plug gets a perfect grip in<br />
any wall, whether in plasterboard, solid bricks, perforated<br />
bricks or concrete.<br />
Same retaining power as the standard plug<br />
The ‘Organic Plug’ is made of the Zytel ® RS polyamide<br />
by DuPont, 58 % by wt. of which consist of renewable<br />
base materials. “Extensive tests and long-term trials<br />
have shown that the UX made of this new material has<br />
the same values as the tried and tested product made<br />
of conventional nylon”, says Rainer Fischer, head of<br />
synthetics development at fischer. In continuous tests,<br />
the ‘Organic Plug’ consistently shows the same retaining<br />
values as the conventional UX. Investigations involving the<br />
performance at high temperatures also show the same<br />
temperature resistance for both plugs.<br />
The UX Plugs recently shown at FAKUMA, a German<br />
plastics trade fair, are the first prototypes presented to<br />
a wider public. “Our aim is not only to demonstrate that<br />
we can make plugs from sustainable and renewable<br />
materials”, says Rainer Fischer. “We also want to fathom<br />
out the market acceptance because the ‘Organic Plugs’<br />
can currently not be made with the same cost structure as<br />
the standard plug”.<br />

Gourmet<br />
Canadian Packaging<br />
A<br />
Canadian company, Nature’s Farm, is going to wrap<br />
its range of gourmet pasta products in NatureFlex NE<br />
from Innovia Films.<br />
Founded in 1987 in Steinbach, Manitoba, Nature’s Farm is a<br />
family-owned business with a poultry operation producing eggs.<br />
In 1993 after several years of careful research and some time as<br />
a ‘designer-egg’ wholesaler, they introduced Nature’s Pasta,<br />
which now appears on the menus of some of North America’s<br />
best eating establishments.<br />
The farm’s fresh free-range eggs (from hens fed an allnatural<br />
vegetarian diet) go through a stringent quality inspection<br />
before being shipped to the nearby pasta-making facility. Strict<br />
adherence to old-world, small-batch production methods has<br />
created gourmet pasta that is setting new standards in taste,<br />
texture, and quality. The products are packed in-house on a<br />
Bosch Terra 25 VFFS machine set up to run at 15ppm.<br />
According to company founder, Hermann Grauer, NatureFlex<br />
is an ideal packaging choice, “We are committed to ecological<br />
sustainability and stewardship. NatureFlex has fitted into our<br />
production line process with only minimal adjustment required.<br />
The reaction of our customers’ to the packaging has also been<br />
very positive and enthusiastic.”<br />
“NatureFlex is a very versatile product,” stated Christopher<br />
Tom, Innovia Films’ Account Executive, Canada, “we are delighted<br />
to support Nature’s Farm by providing packaging that aligns<br />
with their environmentally and socially responsible values.” For<br />
a packaging like a pasta bag, a good sealability is important.<br />
NatureFlex NE was used in this application as it offers the best<br />
seal performance in the NatureFlex range of products.<br />

Evaluating Quantity,<br />
Quality and Comparability<br />
of Biopolymer Materials<br />
Article contributed by<br />
Hans-Josef Endres,<br />
Andrea Siebert-Raths,<br />
and Maren Bengs,<br />
all University of Applied Sciences<br />
and Arts, Hanover, Germany<br />
Rather than biodegradability the focus of current material development<br />
in the field of biopolymers is increasingly on a biobased raw material input<br />
to produce durable products, i.e. the use of resistant biopolymers in<br />
technical applications. And the properties required of the materials are increasing<br />
in parallel with the number of these different applications.<br />
As a result of this current development more and more manufacturers<br />
are publishing material specifications. At first glance this can be seen as a<br />
positive move from the point of view of technical marketing support, however,<br />
the quantity, quality and comparability of available material data are still very<br />
unsatisfactory. When establishing such product data it is often the case, for<br />
example, that different standards are used for the tests, as well as different<br />
testing conditions, such as the prevailing environment when the sample was<br />
taken, the temperature conditions or humidity before and during the test, or the<br />
period of time over which the test was conducted. A further problem area lies in<br />
the fact that too little experience has been gained with new types of biopolymer<br />
to be able to lay down the optimum test conditions. Furthermore many of the<br />
published test results do not specify any standard test methods or conditions, or<br />
do not adequately define the selected conditions. Unfortunately consequence it<br />
is often in the case that the material performance specifications published until<br />
now have limited informative value.<br />
The intention of this article is, with the help of various concrete examples, to<br />
point out some of the common mistakes made when attempting to ascertain the<br />
performance characteristics of biopolymers and to increase the understanding<br />
of testing of biopolymers.<br />
Melt Index<br />
An important value for plastics processors is, for example, the melt flow index<br />
(Melt mass flow rate = MFR [g/10 min]) as specified in DIN EN ISO 1133. Without<br />
quoting a temperature and the pressure applied as the significant parameters<br />
for the test, the readings cannot be evaluated. These data, which complement the<br />
values quoted, are therefore essential but are left out by many manufacturers and<br />
are missing from numerous published documents. In addition, with biopolymers<br />
there is often the problem that, unlike conventional plastics, the MFR of these<br />
new polymers no recommendations are given with regard to the test parameters<br />
when measuring. This leads to different companies choosing different test<br />
parameters, hence making it even more difficult to compare readings.<br />
Temperature Resistance<br />
Another very sensitive figure that should be known for practical application<br />
of a biopolymer is its resistance to temperature. In many documents published<br />
about biopolymers, or in press releases, we more and more often read, for<br />
38 bioplastics MAGAZINE [06/09] Vol. 4
Basics<br />
instance, about PLA/PLA blends with a temperature resistance of<br />
around 100°C. Since the low temperature resistance of PLA often<br />
seriously limits its use, this increase from the figure of about 60°C<br />
(which is normally quoted for this material) to values around 100°C is<br />
extremely significant. Unfortunately it has emerged that this impressive<br />
figure is not supported by the facts but can largely be traced back to<br />
widely varying test methods that are not really comparable. Here too it<br />
is absolutely essential that one is given details of the test method and<br />
conditions with regard to heat resistance values.<br />
To measure heat resistance the following two different standard test<br />
methods are generally used:<br />
Measuring HDT (Heat Deflection Temperature or Heat Distortion<br />
Temperature) in accordance with DIN EN ISO 75 and measuring the<br />
VST (Vicat Softening Temperature) in accordance with DIN EN ISO<br />
306. For the HDT test a standard sample is placed in an oil bath and<br />
subjected to a defined and constant bending force under a constantly<br />
increasing temperature (120°C/h). The HDT is reached when the<br />
outer fibre distortion of the material reaches 0.2 %. In the Vicat test<br />
the sample is also placed in an oil bath with a defined temperature<br />
gradient. However the Vicat test is not based on bending but on point<br />
load deflection. The Vicat softening temperature is reached when a<br />
flat-ended needle of a defined geometry, penetrates 1 mm into the<br />
sample under a defined pressure [1].<br />
Both methods permit variations of the load and temperature<br />
gradient within the norm. With the HDT method the central bending<br />
load can be chosen from the following values: 1.85 MPa (HDT A),<br />
0.45 MPa (HDT B) and 8.0 MPa (HDT C). This means that even within one<br />
method there can be significant variations in the value depending on<br />
the chosen loading, which is often not specified in the quoted results,<br />
as can be seen in Fig. 1. If, for example, the temperature resistance of<br />
polyhydroxyalkanoates (PHA) is published it may seem high, returning<br />
a value of 140°C, or, with a greater loading, be as much as 60°C lower<br />
at about 80°C.<br />
The situation is similar with the VST temperature resistance test.<br />
Here too the piercing needle force can be selected from either 10 N<br />
(VST A) or 50 N (VST B). In the VST method A represents a lower loading<br />
and hence higher resistance values, whilst method B, uses higher<br />
loading and hence a lower resistance value in contrast to method A.<br />
When comparing the temperature resistance of biopolymers the two<br />
methods can return figures that vary by as much as 100°C.<br />
Furthermore when testing temperature resistance either of two<br />
temperature gradients may be selected; either 50°C/h or 120°C/h. At<br />
the faster rate the thermodynamic loading time of the biopolymer before<br />
reaching a certain temperature is less than at a lower temperature<br />
gradient. Hence the resulting values at the higher temperature gradient<br />
are likewise correspondingly higher.<br />
It is therefore essential that the exact and full methodology used<br />
when measuring temperature resistance is specified. Where adequate<br />
data on the test methods is not supplied the temperature resistance<br />
cannot be properly evaluated.<br />

For the values obtained using the VST test it is thus necessary to<br />
clearly distinguish between results obtained using, for example, VST<br />
A 50 (load applied to the needle = 10 N and temperature gradient =<br />
50°C/h), VST A 120 (10 N @ 120°C/h), VST B 50 (50 N @ 50°C/h) and VST<br />
B 120 (50 N @ 120°C/h) [1].<br />
Without these data mistakes are often made in the practical<br />
application of biopolymers, such as PLA, due to a lack of understanding<br />
of this problem and directly comparing temperature resistance values<br />
that have been obtained using different test methods and/or under<br />
different test parameters. As shown in the table of temperature<br />
resistance figures obtained using Vicat A and HDT A for various<br />
biopolymers (Fig. 2), these results are not at all comparable.<br />
Alongside the often inadequate data concerning the test parameters<br />
there are other factors (such as storage time and/or conditioning/<br />
drying) that are not given with regard to the biopolymers being tested.<br />
The chart in Fig 3 uses as an example the tensile strength of a polyvinyl<br />
alcohol (PVAL) based biopolymer to demonstrate the significant effect<br />
that humidity and/or length of storage may have on the mechanical<br />
properties of the material. It is important, when testing in line with<br />
an international standard, to supply information on the storage and<br />
conditioning of the sample as well as how much time elapsed between<br />
preparation of the sample and the actual test.<br />
Fig. 4 also shows that with biopolymers it is not only conditioning<br />
and the age of the finished components that have a significant impact,<br />
but that also the effect of exceeding recommended storage times of<br />
the resins before processing is a factor not to be underestimated. The<br />
following chart shows the impact on a starch based biopolymer of<br />
exceeding the storage times.<br />
The starch based polymer was tested immediately on delivery and<br />
then after a clearly excessive storage period. The almost quadruple<br />
melt flow index points to a reduction in the length of the molecular<br />
chain as a result of the polymer degradation. The same applies to the<br />
tensile strength. Here again the material was tested immediately upon<br />
delivery and again after an extended storage period. The significant<br />
drop of the mechanical specification also points clearly to a molecular<br />
breakdown.<br />
Barrier Properties of Films<br />
Further examples of a lack of data when evaluating biopolymers is<br />
also seen in the area of biopolymer films. This can be testing oxygen<br />
permeability in line with DIN 53380 for example. In this process a<br />
permeation cell is separated by a sample of the film. The test gas, i.e.<br />
the oxygen, is introduced into one half of the cell. It will permeate to a<br />
greater or less degree through the film and into the other half of the<br />
cell where it is perceived by a carrier gas. A sensor and appropriate<br />
software are used to measure the amount of oxygen in the carrier gas<br />
and so determine the oxygen permeability of the film. In addition to<br />
temperature, the relative humidity of the oxygen and the carrier gas<br />
can also be regulated. When stating the barrier property of a film, i.e.<br />
the coefficient of permeation, the temperature and relative humidity<br />
parameters often fail to be supplied, but as can be seen in Fig. 5 the<br />
moisture content of the oxygen (or other gases being tested), and the<br />
carrier gas have a significant influence on the permeability especially<br />
of biopolymers.<br />
40 bioplastics MAGAZINE [06/09] Vol. 4
Basics<br />
Film Thickness<br />
Another difficulty with biopolymer film lies in the presentation of<br />
performance data without mentioning the film thickness. With barrier<br />
performance in particular it is important to state the film thickness<br />
concerned or to adhere to a recognised standard with a unified film<br />
thickness. In some published data we still find barrier properties of<br />
film being quoted without any mention of the thickness.<br />
Test Speed<br />
A further shortcoming with regard to biopolymer film lies in the<br />
testing of its mechanical performance and in particular the tensile<br />
test. With regard to the speed applied during the tensile test there<br />
is no specific standard laid down by DIN EN ISO 527; several speeds<br />
(1, 2, 5, 10, 20, 50, 100, 200, 500 mm/min) may be applied by the tester.<br />
In practice a speed of 1, 2 or 5 mm/min is chosen to determine the<br />
secant modulus. For other mechanical values (e.g. tensile strength)<br />
higher speeds are usually selected. The chart in Fig. 6 shows the effect<br />
of test speed on the secant modulus of a regenerated cellulose film.<br />
As is clear from the illustration, the secant modulus measured at<br />
1 mm/min lies well below that of the modulus measured at the higher<br />
speed by almost 1000 MPa. At the lower speeds the molecular chains<br />
have more time to change shape and orient themselves. Hence the<br />
film is less resistant to elastic deformation.<br />
The effect of testing speed on mechanical values is also seen with<br />
injection moulded parts, but the effect on films, due to their much<br />
reduced thickness, is more significant. Hence, when tensile testing<br />
films in particular, it is very important to have information on the<br />
test speed in order to be better able to assess and compare data on<br />
different materials.<br />
For the future it can be assumed that the development of biopolymers<br />
will move ahead swiftly and more and more materials will be presented<br />
to the market. It is however important at this stage that the performance<br />
characteristics published for new types of biopolymers are comparable<br />
and meaningful.<br />

Basics of<br />
Anaerobic Digestion<br />
Article contributed by<br />
Bruno de Wilde<br />
Organic Waste Systems nv, Ghent, Belgium<br />
Anaerobic digestion: another way of biological solid<br />
waste treatment<br />
Within biological solid waste treatment a distinction can<br />
be made between two major categories, one being aerobic<br />
composting and the other being anaerobic digestion (AD) or<br />
biogasification .<br />
In composting, organic matter is degraded by a microbial<br />
population consisting of bacteria and fungi, that consume the<br />
organic matter together with oxygen and produce CO 2<br />
, water,<br />
biomass (compost or humus) and a lot of heat. Due to this<br />
exothermic process, the temperature in a composting pile<br />
increases significantly. In anaerobic digestion, organic matter<br />
is degraded by a microbial population consisting of bacteria<br />
in the absence of oxygen and producing CH 4<br />
(methane) and<br />
CO 2<br />
(this mixture often being referred to as ‘biogas‘) and<br />
compost with practically no exothermic heat. When collected<br />
properly this biogas can be exploited in a CHP (Combined<br />
Heat and Power) system, producing electricity and heat, or<br />
can be upgraded to biomethane. To put it simply, the energy<br />
present in wet, organic waste is released as biogas instead<br />
of heat as in composting. Typically from 1 tonne of biowaste<br />
120 m 3 of biogas can be produced, with a total electricity yield of<br />
250 kWh and a net electricity yield of 200 kWh.<br />
In industrial composting the different technologies are<br />
rather similar and the differences lie in relatively minor<br />
aspects (e.g. aeration by over- pressure or under-pressure,<br />
Aerobic composting (open windrow) at Tenneville (Belgium)<br />
the form of the waste heaps, etc) with little or no consequence<br />
for the treatment of bioplastics. In contrast, rather different<br />
technologies can be distinguished in anaerobic digestion. One<br />
distinction between different technologies is the temperature<br />
at which the anaerobic digestion is operated. Temperature<br />
is externally controlled and digesters are run either at<br />
mesophilic temperature (35-40°C), or at thermophilic<br />
temperature (50-55°C). These are two distinct temperature<br />
zones at which different types of anaerobic bacteria show<br />
maximum activity (namely mesophilic and thermophilic<br />
bacteria). The rate of activity is higher at thermophilic<br />
temperature. Further, anaerobic digestion can be a singlephase<br />
or a two-phase process. In a single-phase process<br />
the complete digestion takes place in one unit or digester.<br />
In two-phase fermentation the first phase (hydrolysis and<br />
acidification) and the subsequent methanogenic phase are<br />
run in separate tanks. The distinction between single-phase<br />
and two-phase is referred to as a distinction between dry and<br />
wet fermentation systems. In dry anaerobic digestion the<br />
process is run at a moisture content of < 85%, while in wet<br />
systems the process is run at a moisture level of >85%.<br />
These technical differences have rather far-reaching<br />
consequences with regard to the treatment of bioplastics.<br />
For example, certain bioplastics (e.g. PLA) need an elevated<br />
temperature (50-60°C) to start biodegrading. In thermophilic<br />
anaerobic digestion this temperature is met and these<br />
bioplastics will degrade. However, in mesophilic anaerobic<br />
digestion where the temperature is lower, these bioplastics<br />
will not readily biodegrade.<br />
Practically all commercial anaerobic digestion systems<br />
feature a combination of an anaerobic fermentation first step,<br />
and a subsequent, aerobic composting, stabilisation second<br />
step. Since fermentation is something of a mixed process<br />
the output is not fully stabilised or fermented (note: mixing<br />
can be done in the reactor or outside the reactor by blending<br />
residue output with new feedstock input). In order to reduce<br />
the residual biological activity and to obtain complete maturity<br />
of the compost end product, the residue from the anaerobic<br />
digestion phase is therefore aerobically composted for a short<br />
time (typically for 2-4 weeks).<br />

Basics<br />
Anaerobic digestion plant (single-phase) at Würselen (Germany)<br />
Even though anaerobic digestion can be applied to very<br />
different types of waste streams, it is particularly suited to<br />
organic waste with a high moisture content such as kitchen<br />
waste and food waste. Anaerobic digestion plants have<br />
been built and have been operational for many years for<br />
the treatment of mixed, municipal solid waste, for biowaste<br />
(obtained after source separated waste collection), for<br />
residual waste and for many types of industrial waste.<br />
The major differences from aerobic composting include<br />
the production of energy, less odour production, less health<br />
risk (i.e. killing off of pathogens, typical for thermophilic<br />
digestion), less need for surface area (smaller footprint), and a<br />
higher level of technology. Consequently, anaerobic digestion<br />
is often the preferred biological waste treatment option in<br />
densely populated areas such as big cities or countries such<br />
as Japan or Korea.<br />
Recently, anaerobic digestion has also become an important<br />
player in the area of renewable energy production from energy<br />
crops (e.g. corn). The net energy yield per hectare is higher<br />
compared to the production of bio-diesel or bio-ethanol. Also,<br />
in bio-refineries, anaerobic digestion could play an important<br />
role with high-value plant parts being used for green chemistry<br />
and residual vegetable matter (after processing of low-value<br />
plant parts, such as stems and leaves or straw) being treated<br />
in anaerobic digestion for production of energy and compost.<br />
Current distribution and prospective of technology<br />
Figure 1 below gives an overview of the development of<br />
biogasification capacity in Europe in the last two decades.<br />
From just three plants in Europe with a total capacity of<br />
87,000 tonnes per year in 1990, European anaerobic digestion<br />
facilities have now grown to a total of 171 plants with a<br />
digestion capacity of more than 5 million tonnes per year<br />
in 2010. Figure 2 gives an overview of the AD capacities in<br />
different European countries. Both the total capacity in a<br />
given country is quoted as well as the average capacity per<br />
plant. As can be seen, some countries tend to have smaller<br />
plants (e.g. Germany, Switzerland, Austria, …) while others<br />
have larger installations (e.g. Spain, France).<br />
These graphs also show that the anaerobic digestion<br />
capacity in Europe is increasing rapidly. Many digesters are<br />
being built in Mediterranean countries such as Spain and<br />
France. Most plants are dry and single-phase, and run at<br />
mesophilic temperatures.<br />
The evolution for the coming years can be deduced from<br />
the two graphs, the data for which are based on the bids for<br />
proposals published in the European Journal.<br />

Basics<br />
should be biodegradable in order to be compatible. Whether bioplastics are produced from<br />
renewable resources or not, doesn‘t matter. The key element is that they must be biodegradable<br />
under anaerobic conditions or at least be compatible with an anaerobic digestion process.<br />
Anaerobic digestion plant<br />
in (two-phase) at Vitoria<br />
(Spain) (all photos: OWS nv)<br />
Concerning technical preconditions of treating bioplastics in anaerobic digestion plants, a<br />
distinction must be made between wet and dry technologies. In general, wet technologies,<br />
especially in the pretreatment phase, cannot treat bioplastics easily: in the first pulping and<br />
hydrolysis phase they are removed either by flotation or by sedimentation and therefore are not<br />
really entering the digestion (except when bioplastics are quickly soluble or dispersible, which is<br />
rarely the case). A solution could be to add the bioplastics directly to the second step, the aerobic<br />
composting step (considering the retention time in this second step is much shorter than the<br />
residence time in a typical composting process). Another solution might be new developments<br />
in the pretreatment phase. In most dry systems, bioplastics can be added when some random<br />
conditions are fulfilled: they should be shredded (to reduce the particle size) before entering the<br />
digestion (just like biowaste itself) and sieving is better located at the end of the process in order<br />
to enable as much biodegradation and disintegration as possible in both the anaerobic digestion<br />
and the aerobic composting step.<br />
The major underlying reason why several bioplastics show a different biodegradation behavior<br />
in aerobic composting from their behavior in anaerobic digestion is the influence of fungi. Fungi<br />
are abundantly available and very active in aerobic composting while in anaerobic fermentation no<br />
fungi are active. Some polymers are mainly (or even only) degraded by fungi and not by bacteria<br />
and will therefore biodegrade in aerobic composting and not in anaerobic digestion - or only much<br />
slower. As a matter of fact, this is also the case for the natural polymer lignin which can be found<br />
in wood, straw, shells, etc.<br />
On the other hand, when bioplastics do also biodegrade in anaerobic fermentation there is<br />
a double benefit. First of all, energy is produced from the bioplastics in the form of biogas that<br />
can be converted to electricity. Secondly, as most bioplastics are very rich in carbon and do not<br />
contain nitrogen (or very little), the addition of bioplastics to biowaste will improve the C/N ratio<br />
of the mixture. Biowaste tends to be low in C/N, which is sometimes a problem in anaerobic<br />
digestion, by adding a carbon-rich substrate the C/N ratio is increased.<br />
So far, the knowledge of anaerobic biodegradation and treatability of bioplastics is limited and<br />
further research would be welcome. Ideally, bioplastics would biodegrade and also disintegrate<br />
during the anaerobic phase in an anaerobic digestion plant, just as the major part of ‘natural‘<br />
biowaste does. However, if the bioplastic disintegrates during the anaerobic phase and then<br />
afterwards biodegrades completely during the aerobic stabilization phase or during the use of<br />
digestate or compost in soil, it can also considered to be compatible with anaerobic digestion.<br />

Glossary<br />
In bioplastics MAGAZINE again and again<br />
the same expressions appear that some of our<br />
readers might (not yet) be familiar with. This<br />
glossary shall help with these terms and shall<br />
help avoid repeated explanations such as ‘PLA<br />
(Polylactide)‘ in various articles.<br />
Bioplastics (as defined by European Bioplastics<br />
e.V.) is a term used to define two different<br />
kinds of plastics:<br />
a. Plastics based on renewable resources (the<br />
focus is the origin of the raw material used)<br />
b. à Biodegradable and compostable plastics<br />
according to EN13432 or similar standards<br />
(the focus is the compostability of the final<br />
product; biodegradable and compostable<br />
plastics can be based on renewable (biobased)<br />
and/or non-renewable (fossil) resources).<br />
Bioplastics may be<br />
- based on renewable resources and biodegradable;<br />
- based on renewable resources but not be<br />
biodegradable; and<br />
- based on fossil resources and biodegradable.<br />
Amylopectin | Polymeric branched starch<br />
molecule with very high molecular weight (biopolymer,<br />
monomer is à Glucose).<br />
Amyloseacetat | Linear polymeric glucosechains<br />
are called à amylose. If this compound<br />
is treated with ethan acid one product<br />
is amylacetat. The hydroxyl group is connected<br />
with the organic acid fragment.<br />
Amylose | Polymeric non-branched starch<br />
molecule with high molecular weight (biopolymer,<br />
monomer is à Glucose).<br />
Biodegradable Plastics | Biodegradable<br />
Plastics are plastics that are completely assimilated<br />
by the à microorganisms present a<br />
defined environment as food for their energy.<br />
The carbon of the plastic must completely be<br />
converted into CO 2 during the microbial process.<br />
For an official definition, please refer to<br />
the standards e.g. ISO or in Europe: EN 14995<br />

neutrality means that any CO 2 released when<br />
a plant decomposes or is burnt is offset by an<br />
equal amount of CO 2 absorbed by the plant<br />
through photosynthesis when it is growing.<br />

under ‘composting’ conditions:<br />
specified humidity, temperature, à microorganisms<br />
and timefame. Several national<br />
and international standards exist for clearer<br />
definitions, for example EN 14995 Plastics<br />
- Evaluation of compostability - Test scheme<br />
and specifications [bM 02/2006 p. 34f, bM<br />
01/2007 p38].<br />
Composting | A solid waste management<br />
technique that uses natural process to convert<br />
organic materials to CO 2 , water and humus<br />
through the action of à microorganisms<br />
[bM 03/2007].<br />
Copolymer | Plastic composed of different<br />
monomers.<br />
Cradle-to-Gate | Describes the system<br />
boundaries of an environmental àLife Cycle<br />
Assessment (LCA) which covers all activities<br />
from the ‘cradle’ (i.e., the extraction of raw<br />
materials, agricultural activities and forestry)<br />
up to the factory gate<br />
Cradle-to-Cradle | (sometimes abbreviated<br />
as C2C): Is an expression which communicates<br />
the concept of a closed-cycle economy,<br />
in which waste is used as raw material (‘waste<br />
equals food’). Cradle-to-Cradle is not a term<br />
that is typically used in àLCA studies.<br />
Cradle-to-Grave | Describes the system<br />
boundaries of a full àLife Cycle Assessment<br />
from manufacture (‘cradle’) to use phase and<br />
disposal phase (‘grave’).<br />
Fermentation | Biochemical reactions controlled<br />
by à microorganisms or enyzmes (e.g.<br />
the transformation of sugar into lactic acid).<br />
Gelatine | Translucent brittle solid substance,<br />
colorless or slightly yellow, nearly tasteless<br />
and odorless, extracted from the collagen inside<br />
animals‘ connective tissue.<br />
Glucose | Monosaccharide (or simple sugar).<br />
G. is the most important carbohydrate (sugar)<br />
in biology. G. is formed by photosynthesis or<br />
hydrolyse of many carbohydrates e. g. starch.<br />
Humus | In agriculture, ‘humus’ is often used<br />
simply to mean mature à compost, or natural<br />
compost extracted from a forest or other<br />
spontaneous source for use to amend soil.<br />
Hydrophilic | Property: ‘water-friendly’, soluble<br />
in water or other polar solvents (e.g. used<br />
in conjunction with a plastic which is not waterresistant<br />
and weatherproof or that absorbs<br />
water such as Polyamide (PA).<br />
Hydrophobic | Property: ‘water-resistant’, not<br />
soluble in water (e.g. a plastic which is waterresistant<br />
and weatherproof, or that does not<br />
absorb any water such as Polethylene (PE) or<br />
Polypropylene (PP).<br />
LCA | Life Cycle Assessment (sometimes also<br />
referred to as life cycle analysis, ecobalance,<br />
and àcradle-to-grave analysis) is the investigation<br />
and valuation of the environmental<br />
impacts of a given product or service caused<br />
(bM 01/2009).<br />

Basics<br />
Readers who know better explanations or who<br />
would like to suggest other explanations to be<br />
added to the list, please contact the editor.<br />
[*: bM ... refers to more comprehensive article<br />
previously published in bioplastics MAGAZINE)<br />
Microorganism | Living organisms of microscopic<br />
size, such as bacteria, funghi or yeast.<br />
PCL | Polycaprolactone, a synthetic (fossil<br />
based), biodegradable bioplastic, e.g. used as<br />
a blend component.<br />
PHA | Polyhydroxyalkanoates are linear polyesters<br />
produced in nature by bacterial fermentation<br />
of sugar or lipids. The most common<br />
type of PHA is à PHB.<br />
PHB | Polyhydroxyl buteric acid (better poly-<br />
3-hydroxybutyrate), is a polyhydroxyalkanoate<br />
(PHA), a polymer belonging to the polyesters<br />
class. PHB is produced by micro-organisms<br />
apparently in response to conditions of physiological<br />
stress. The polymer is primarily a<br />
product of carbon assimilation (from glucose<br />
or starch) and is employed by micro-organisms<br />
as a form of energy storage molecule to<br />
be metabolized when other common energy<br />
sources are not available. PHB has properties<br />
similar to those of PP, however it is stiffer and<br />
more brittle.<br />
PLA | Polylactide or Polylactic Acid (PLA) is<br />
a biodegradable, thermoplastic, aliphatic<br />
polyester from lactic acid. Lactic acid is made<br />
from dextrose by fermentation. Bacterial fermentation<br />
is used to produce lactic acid from<br />
corn starch, cane sugar or other sources.<br />
However, lactic acid cannot be directly polymerized<br />
to a useful product, because each polymerization<br />
reaction generates one molecule<br />
of water, the presence of which degrades the<br />
forming polymer chain to the point that only<br />
very low molecular weights are observed.<br />
Instead, lactic acid is oligomerized and then<br />
catalytically dimerized to make the cyclic lactide<br />
monomer. Although dimerization also<br />
generates water, it can be separated prior to<br />
polymerization. PLA of high molecular weight<br />
is produced from the lactide monomer by<br />
ring-opening polymerization using a catalyst.<br />
This mechanism does not generate additional<br />
water, and hence, a wide range of molecular<br />
weights are accessible (bM 01/2009).<br />
Saccharins or carbohydrates | Saccharins or<br />
carbohydrates are name for the sugar-family.<br />
Saccharins are monomer or polymer sugar<br />
units. For example, there are known mono-,<br />
di- and polysaccharose. à glucose is a monosaccarin.<br />
They are important for the diet and<br />
produced biology in plants.<br />
Sorbitol | Sugar alcohol, obtained by reduction<br />
of glucose changing the aldehyde group<br />
to an additional hydroxyl group. S. is used as a<br />
plasticiser for bioplastics based on starch.<br />
Starch | Natural polymer (carbohydrate) consisting<br />
of à amylose and à amylopectin,<br />
gained from maize, potatoes, wheat, tapioca<br />
etc. When glucose is connected to polymerchains<br />
in definite way the result (product) is<br />
called starch. Each molecule is based on 300<br />
-12000-glucose units. Depending on the connection,<br />
there are two types à amylose and<br />
à amylopectin known.<br />
Starch (-derivate) | Starch (-derivates) are<br />
based on the chemical structure of à starch.<br />
The chemical structure can be changed by<br />
introducing new functional groups without<br />
changing the à starch polymer. The product<br />
has different chemical qualities. Mostly the<br />
hydrophilic character is not the same.<br />
Starch-ester | One characteristic of every<br />
starch-chain is a free hydroxyl group. When<br />
every hydroxyl group is connect with ethan<br />
acid one product is starch-ester with different<br />
chemical properties.<br />
Starch propionate and starch butyrate |<br />
Starch propionate and starch butyrate can<br />
be synthesised by treating the à starch with<br />
propane or butanic acid. The product structure<br />
is still based on à starch. Every based à<br />
glucose fragment is connected with a propionate<br />
or butyrate ester group. The product is<br />
more hydrophobic than à starch.<br />
Sustainable | An attempt to provide the best<br />
outcomes for the human and natural environments<br />
both now and into the indefinite future.<br />
One of the most often cited definitions of sustainability<br />
is the one created by the Brundtland<br />
Commission, led by the former Norwegian<br />
Prime Minister Gro Harlem Brundtland. The<br />
Brundtland Commission defined sustainable<br />
development as development that ‘meets the<br />
needs of the present without compromising<br />
the ability of future generations to meet their<br />
own needs.’ Sustainability relates to the continuity<br />
of economic, social, institutional and<br />
environmental aspects of human society, as<br />
well as the non-human environment).<br />
Sustainability | (as defined by European<br />
Bioplastics e.V.) has three dimensions: economic,<br />
social and environmental. This has<br />
been known as “the triple bottom line of<br />
sustainability”. This means that sustainable<br />
development involves the simultaneous pursuit<br />
of economic prosperity, environmental<br />
protection and social equity. In other words,<br />
businesses have to expand their responsibility<br />
to include these environmental and social<br />
dimensions. Sustainability is about making<br />
products useful to markets and, at the same<br />
time, having societal benefits and lower environmental<br />
impact than the alternatives currently<br />
available. It also implies a commitment<br />
to continuous improvement that should result<br />
in a further reduction of the environmental<br />
footprint of today’s products, processes and<br />
raw materials used.<br />
Thermoplastics | Plastics which soften or<br />
melt when heated and solidify when cooled<br />
(solid at room temperature).<br />
Yard Waste | Grass clippings, leaves, trimmings,<br />
garden residue.<br />
