1. the company<br />

1. the company<br />

2. certification<br />

<strong>The</strong> company was set up in 1957 by a small cooperative<br />

situated near Bologna and owned by Granlatte Società<br />

Cooperativa Agricola, together with which it forms the largest<br />

<strong>milk</strong> chain in Italy, with shares held directly by the farmer<br />

members of the cooperative.<br />

Since the early nineties, the Group has been divided into<br />

two distinct, synergistic structures: a consortium of <strong>milk</strong><br />

producers (Granlatte) – which operates in the farming industry<br />

and collects the raw material – and a joint-stock company<br />

(Granarolo S.p.A.), which controls the industrial and marketing<br />

activities.<br />

Granarolo is one of the leading food-processing companies in<br />

Italy. <strong>The</strong> Group closed the year 2011 with a turnover of about<br />

849 million euros and has:<br />

• 6 production plants distributed across the country;<br />

• 2,083 employees;<br />

• 1,200 refrigerated vehicles for the distribution.<br />

<strong>The</strong> group’s business is divided into 3 main areas: <strong>milk</strong> &<br />

cream, yogurt and dairy products.<br />

Granarolo is the leading Italian company in the sale of fresh<br />

<strong>milk</strong> and organic <strong>milk</strong> and dairy products under an industrial<br />

brand name and is one of the leaders on the market for UHT<br />

<strong>milk</strong> (2nd largest market share), yogurt (3rd) and fresh cheese<br />

(2nd).<br />

<strong>The</strong> central office of Granarolo S.p.A. is situated in Bologna<br />

and it has production plants in several regions of Italy.<br />

2. certification<br />

Granarolo adopts an integrated approach to quality policies<br />

that combines economic, environmental and ethical objectives<br />

along the entire food chain, from the farm to the consumer’s<br />

table.<br />

A path upon which the Company embarked about 15 years<br />

ago, by opting for a high quality strategy that has culminated<br />

today in the traceability of the chain, in the quality, in the<br />

environment and occupational safety.<br />

3. the product<br />

This Environmental Product Declaration <strong>EPD</strong> concerns<br />

the “Piacere Leggero” partly skimmed pasteurized fresh <strong>milk</strong><br />

packaged in one and a half-litre, one-litre and half-litre PET<br />

bottles. <strong>The</strong> “Piacere Leggero” pasteurized fresh <strong>milk</strong> in bottles<br />

solely comes from Italian selected farms and contains only<br />

1,6% of fat.<br />

<strong>The</strong> whole raw <strong>milk</strong> coming from the Granarolo production<br />

plants is subjected to a single pasteurization treatment and<br />

conforms to all the requirements laid down by law 169/89.<br />

<strong>The</strong> standards currently adopted by Granarolo for the raw<br />

material used enable the <strong>milk</strong> to be subjected to a more delicate<br />

pasteurization process so as to make it more similar to <strong>milk</strong><br />

freshly <strong>milk</strong>ed and, in addition, the <strong>milk</strong> is completely safe from<br />

the point of view of health and hygiene.<br />

4. <strong>The</strong> Production Process<br />

<strong>The</strong> production process can be divided into the following four<br />

main phases:<br />

• production and collecting of raw <strong>milk</strong> at the cowsheds and<br />

transport to the plants;<br />

• production of containers;<br />

• industrial <strong>milk</strong> pasteurization and packaging process (Figure<br />

1);<br />

• transport to the distribution platforms (afterwards the <strong>milk</strong><br />

can be distributed to sales points or sent to Transit Point<br />

where the pre-ordered products assembly takes place).<br />

Before being unloaded, the <strong>milk</strong> received is subjected to<br />

an initial incoming test to make sure that it is suitable for<br />

processing. After the refrigerated storage phase (at about 4°C),<br />

the <strong>milk</strong> is transferred to the pasteurization process, which<br />

consists of a continuous flow heat treatment at a temperature<br />

of 76°C for 21” (Figure 2).<br />

<strong>The</strong> phase after the pasteurization process consists in<br />

packaging the <strong>milk</strong> (Figure 3).<br />

<strong>The</strong> process starts with the transformation of the preforms<br />

into bottles, which are transferred to the filling machine and<br />

then labelled and grouped into bundles located on pallets.<br />

<strong>The</strong> so packaged <strong>milk</strong> is then transferred to the distribution<br />

from where it will be distributed directly to the points of sale<br />

or via the Transit Points where the pre-ordered products are<br />

assembled.<br />

5. Method Used<br />

<strong>The</strong> environmental performance of the product was quantified<br />

as laid down in the general rules of the <strong>EPD</strong> Program 1 and in<br />

the specifications of the group of products “Product Category<br />

Rules PCR 2010:12 “Processed liquid Milk” – CPC 2211”, using<br />

the LCA (Life Cycle Assessment) method regulated by the<br />

ISO 14040 series international standards, which are used to<br />

determine environmental impacts in terms of consumption of<br />

resources and atmospheric emissions of a product or service<br />

throughout its life (“from cradle to grave”).<br />

In this specific case, the LCA analysis was developed using<br />

some LCA databases as a further support tool, such as<br />

Ecoinvent, PlasticsEurope, LCA Food (within the software<br />

SimaPro v.7.3.3) and the Boustead Model 2 ; the contribution of<br />

generic data to the end results was less than 10%.<br />

<strong>The</strong> study was conducted on direct suppliers-producers,<br />

who were sent detailed questionnaires to ensure a complete<br />

characterization of their production activity.<br />

<strong>The</strong> data referred to the following periods:<br />

• 2011 for the processes, all production and transport<br />

procedures that take place at the plants in Bologna, Anzio,<br />

Gioia del Colle, Pasturago and Assolac-Castrovillari;<br />

• 2011 for the PET bottle preforms and the PE caps<br />

manufacturers.<br />

As regards the primary farming production and <strong>milk</strong> production<br />

cowsheds, the data refers to 10 sample cowsheds (7 situated in<br />

Northern Italy and 3 in Southern Italy).<br />

<strong>The</strong> functional unit to which the results apply is: 1 Litre of<br />

Granarolo “Piacere Leggero” Milk packaged in PET bottles (1.5<br />

litres, 1-litre and ½-litre bottles).<br />

6. <strong>System</strong> Limits and Main Hypotheses<br />

<strong>The</strong> limits of the system studied include the entire High Quality<br />

Milk production process handled by Granarolo and, to be more<br />

precise, the production of <strong>milk</strong> at the farms, the pasteurization<br />

and packaging at the Granarolo Group and Assolac Castrovillari<br />

plants, the transport to the preliminary storage platforms and<br />

then to the Transit Points.<br />

A detailed diagram of the system analysed is shown in Figure<br />

4, which illustrates three different levels or subsystems for the<br />

following production activities:<br />

Upstream processes<br />

• “farms” raw <strong>milk</strong> production at the cowsheds;<br />

• “production of packaging materials” production of the PET<br />

preforms, of the packaging indicated on the bill of materials of<br />

the bottled Piacere Leggero <strong>milk</strong> and of the auxiliary materials<br />

for the pasteurization process.<br />

Core processes<br />

• “Granarolo process” <strong>milk</strong> pasteurization and packaging<br />

activities.<br />

Downstream processes<br />

• “transport of finished product” the transport of the PETpackaged<br />

Piacere Leggero <strong>milk</strong> to the distribution platforms<br />

and the transit points.<br />

7. Environmental Performance<br />

In accordance with the rules of the <strong>EPD</strong> system, below<br />

are shown the environmental performances referred per<br />

litre of <strong>milk</strong>. As the <strong>milk</strong> is distributed in 1.5, 1 and 0.5 litres<br />

containers, the results will be presented in such a way as<br />

to compare the impacts associated with the use of the two<br />

containers, keeping the functional unit fixed (i.e, the results of<br />

the half-litre container are simply twice those of the impacts of<br />

the one-litre container).<br />

Resources consumption<br />

<strong>The</strong> need for resources is indicated in two separate sections:<br />

renewable resources (Table 3) non-renewable resources (Table<br />

4) and water consumption (Table 5).<br />

Production of waste<br />

Another important data item in the description of the<br />

environmental impacts of the system is the production of<br />

waste. Table 6 shows the total amount of waste produced in<br />

order to produce one litre of “Piacere Leggero” <strong>milk</strong>.<br />

Emissions into the air and water<br />

With regard to the emission of pollutants, the <strong>EPD</strong><br />

<strong>International</strong> <strong>System</strong> lays down that they must be presented<br />

in “aggregate” form, assessing them through indicators that<br />

refer to different types of environmental impact expressed in<br />

terms of appropriate equivalent substances 9 on the basis of the<br />

criteria and specifications present in the system rules.<br />

<strong>The</strong> results of this classification are given in Table 7 below in<br />

which the values refer to one litre of “Piacere Leggero” <strong>milk</strong>.<br />

9<br />

the phases of an lca classification and characterization study entail<br />

identifying a series of potential environmental effects and then<br />

determining which of the impacts identified during the inventory phase<br />

contributes to a given effect (classification). for example, co 2<br />

, co and<br />

hydrocarbons all contribute to the greenhouse effect. another aim of<br />

this phase is to assign a numeric value to the degree to which the process<br />

examined contributes to the potential impacts identified by determining<br />

given environmental indicators (characterization) expressed in quantities<br />

of suitable equivalent substances.<br />

8. Additional Information<br />

Representativeness of the farms<br />

Granarolo acquires the raw material from a large number of<br />

farms, all situated in Italy, which are divided into classes, not<br />

only on the basis of the number of animals but also in terms of<br />

the quantity of <strong>milk</strong> produced per day (expressed in litres/day).<br />

<strong>The</strong> distribution of <strong>milk</strong> producers according to the distinction<br />

made by Granarolo is illustrated in Figure 5, from which it<br />

emerges that most of the <strong>milk</strong> (about 81%) comes from the<br />

cowsheds with a daily production of over 3,000 litres/day.<br />

Primary <strong>milk</strong> production data<br />

<strong>The</strong> primary <strong>milk</strong> production data used for the LCA and to draw<br />

up this Environmental Product Declaration refers to a sample<br />

of 8 farms; in quantitative terms, the production of these<br />

companies was equivalent to 12% of the Piacere Leggero <strong>milk</strong><br />

produced by Granarolo in 2011.<br />

As regards their production, the sample cowsheds belong<br />

to the main categories shown in Figure 5 (> 300 l/g), so as to<br />

guarantee that 99,8% of the Piacere Leggero <strong>milk</strong> produced<br />

and delivered to Granarolo is represented (the cowsheds with a<br />

productivity of less than 300 litres/day, which account for 0,2%<br />

of the <strong>milk</strong> were left out of the sample).<br />

Primary <strong>milk</strong> processing data<br />

<strong>The</strong> primary <strong>milk</strong> processing and packaging data refers to all<br />

the 5 plants indicated in Figure 1 and accounts for 100% of the<br />

production of Granarolo Piacere Leggero <strong>milk</strong> packaged in 1.5,<br />

1 and 0.5 litre PET containers.<br />

Use and end of life of the bottle<br />

<strong>The</strong> impacts associated with the use of the <strong>milk</strong> and<br />

management of the primary packaging after use are closely<br />

correlated with the consumer’s behaviour.<br />

Consumption of Piacere Leggero Milk<br />

As regards the use phase, the main environmental impact<br />

is associated with the storage of the fresh product in the<br />

refrigerator considering that the Piacere Leggero <strong>milk</strong> has a life<br />

of 6 days following pasteurization.<br />

End of life of the primary packaging<br />

<strong>The</strong> white 1-litre PET bottle is a modern remake of the glass<br />

bottle (used in Italy until the seventies); the new container was<br />

designed with a view to combining the value of tradition with<br />

respect for the environment and the need for a more practical<br />

container.<br />

In fact, this container is highly practical, light and ensures<br />

that the product remains fresh; the PET bottle is not just<br />

unbreakable and lighter than the glass bottle, even after it has<br />

been opened it can be set horizontally in the refrigerator as it<br />

has a liquid-proof cap.<br />

Over the past few years, in order to reduce the consumption<br />

of raw materials, Granarolo has gradually reduced the weight of<br />

the bottle, by undertaking a project to this aim in 2001, starting<br />

from a PET bottle weight of 29 g in 2007, reaching 25 g in 2008<br />

and 23.5 g in 2009-2010, these bottles maintaining their shape<br />

and technical characteristics at the same time.<br />

<strong>The</strong> information given in this document refers to all the<br />

phases that can be controlled directly by Granarolo so the end<br />

of life management of the package (waste disposal) lies outside<br />

the limits of the system assessed in the LCA analysis and the<br />

<strong>EPD</strong>, as indicated in the reference PCR.<br />

Nevertheless, in relation to the handling of PET bottles at the<br />

end of their life, it should be pointed out that the environmental<br />

impacts depend mainly on the behaviour of the end user<br />

and the local availability of efficient separate waste collection<br />

services; according to the statistics, on average, PET waste in<br />

Italy 13 is disposed of as follows:<br />

• recycling 41%;<br />

• waste to energy systems 30%;<br />

• delivery to dump 29%.<br />

<strong>The</strong>re are two ways of recycling PET: it can be transformed into<br />

secondary raw material or it can be converted into energy as<br />

illustrated in Figure 6.<br />

Recycling<br />

PET recycling eliminates the need to<br />

produce granules from natural raw<br />

materials.<br />

Waste of energy<br />

One PET bottle has a calorific power<br />

(feedstock energy) of about 1 MJ, which<br />

may be converted into usable energy.<br />

8. Additional<br />

Information<br />

<strong>The</strong> production of 23.5 g of virgin PET<br />

granules uses up about 40 g of energy<br />

resources (oil, gas and coal) and an<br />

equivalent amount of about 80 g of CO 2<br />

is<br />

emitted. Source: Plastics Europe<br />

1 bottle =<br />

23.5 grams of PET<br />

1 MJ of energy corresponds to about 0.025<br />

Nm³ of natural gas or 0.026 litres of diesel<br />

oil and is sufficient for an average-engine<br />

car to travel about 400 m.<br />

Acidification Potential (AP)<br />

Ozone Depletion Potential<br />

(ODP)<br />

Global Warming Potential<br />

(GWP)<br />

Gross Energy Requirements<br />

(GER)<br />

Eutrophication Potential (EP)<br />

<strong>The</strong> characteristic of rain or<br />

other form of precipitation<br />

having a lower than normal<br />

pH, it may have harmful effects<br />

on forests, crops, aquatic<br />

animals and infrastructure.<br />

It is caused by SO 2<br />

, NO x<br />

and<br />

NH 3<br />

emissions, which are thus<br />

included in the Acidification<br />

Potential (AP) indicator,<br />

expressed in moles of H +<br />

produced.<br />

Amount of degradation<br />

caused to the ozone layer,<br />

which performs the function<br />

of blocking ultraviolet light,<br />

by particularly reactive<br />

compounds that derive from<br />

chlorofluorocarbons (CFC)<br />

or chlorofluoromethanes<br />

(CFM). <strong>The</strong> substance used<br />

as a reference for the ODP is<br />

trichlorofluoromethane, or<br />

CFC-11.<br />

Amount by which the infrared<br />

radiation emitted by the<br />

Earth’s surface following<br />

solar radiation is absorbed<br />

by molecules present in the<br />

atmosphere and re-emitted in<br />

the form of heat, thus warming<br />

the entire atmosphere. This<br />

GWP indicator measures above<br />

all the emissions of carbon<br />

dioxide, the main greenhouse<br />

gas, but also other gases with<br />

lower degrees of infrared ray<br />

absorption, such as methane<br />

(CH 4<br />

), nitrogen protoxide<br />

(N 2<br />

O) and chlorofluorocarbons<br />

(CFC), and is expressed as<br />

the equivalent amount of CO 2<br />

absorbed (g CO 2<br />

).<br />

<strong>The</strong> total amount of energy<br />

required by a production<br />

system and made up of the<br />

sum of the energy values<br />

corresponding to all the<br />

operations from which it is<br />

derived, starting from the<br />

extraction of raw materials.<br />

Gross energy may be divided<br />

into at least five types: direct<br />

energy or energy content<br />

of fuel, feedstock energy,<br />

production & delivery energy,<br />

transport energy and biomass<br />

energy.<br />

<strong>The</strong> potential of nutrients<br />

to cause overfertilization of<br />

water, which may in turn cause<br />

increased growth of biomass<br />

due to the lack of nutrient<br />

limitation. <strong>The</strong> Eutrophication<br />

Potential (EP) depends mainly<br />

on the phosphorus and<br />

nitrogen salts present and is<br />

expressed as an equivalent<br />

amount of oxygen (g O 2<br />

).<br />

Photochemical Oxidants<br />

Creation Potential (POCP)<br />

Downstream processes<br />

Core processes<br />

Upstream processes<br />

<strong>The</strong> potential to produce<br />

compounds that, in the<br />

presence of light, trigger an<br />

oxidation reaction that leads<br />

to the production of ozone in<br />

the troposphere. <strong>The</strong> POCP<br />

indicator concerns above<br />

all VOC (volatile organic<br />

compounds) and is expressed<br />

as an equivalent amount of<br />

ethylene (g C 2<br />

Phases subsequent to the main<br />

production process concerning<br />

the transport of the product<br />

to the point of sale/end<br />

user, the use of the product,<br />

the maintenance activities<br />

(defined in the instructions<br />

booklet, if provided) and<br />

the end of its life. For<br />

services (Core Process),<br />

no Downstream Processes<br />

are normally identified<br />

(e.g. waste management is<br />

already included in the Core<br />

Processes).<br />

Phases of the process<br />

directly associated with the<br />

construction/provision of the<br />

product/service concerned<br />

by the <strong>EPD</strong> (these phases<br />

include the transport of<br />

main components by the<br />

supplier to the production<br />

plant and the handling of the<br />

waste produced). Normally,<br />

the construction of the<br />

structures/infrastructure/<br />

plants/equipment and the staff<br />

activities associated with the<br />

product are not included 14 .<br />

Phases prior to the main<br />

process such as the extraction<br />

and processing of raw<br />

materials, the production of<br />

semifinished products and the<br />

transport of components/parts<br />

of products along the supply<br />

chain to the distribution points.<br />

14<br />

if a significant part of the total impact is associated with the construction of the production site/equipment (e.g.<br />

photovoltaic panels for the production of energy), the significant facility/infrastructure construction and disposal<br />

phases must be considered applying specific cut-off rules.<br />
