Poly-3-hydroxybutyrate<br />
The biopolymer poly-3-hydroxybutyrate (PHB) is a<br />
polyester produced by certa<strong>in</strong> bacteria as they<br />
process glucose or starch. Its characteristics are<br />
similar to those of petroplastic polypropylene.<br />
The South Americ<strong>an</strong> sugar <strong>in</strong>dustry has decided<br />
to exp<strong>an</strong>d PHB production to <strong>an</strong> <strong>in</strong>dustrial scale.<br />
PHB c<strong>an</strong> be used for production of tr<strong>an</strong>sparent<br />
film that is biodegradable without residue.<br />
Polyamide 11<br />
Polyamide 11 (PA 11) is a biopolymer derived<br />
from natural oil. It is also known by the trade<br />
name Rils<strong>an</strong> B, commercialised by Arkema. PA 11<br />
belongs to the technical polymers family <strong>an</strong>d is<br />
not biodegradable. PA 11 is used <strong>in</strong> high<br />
perform<strong>an</strong>ce applications such as automotive fuel<br />
l<strong>in</strong>es, pneumatic airbrake tub<strong>in</strong>g, electrical <strong>an</strong>titermite<br />
cable sheath<strong>in</strong>g, oil <strong>an</strong>d gas flexible<br />
pipes, sports shoes, electronic device<br />
components <strong>an</strong>d catheters.<br />
Genetically modified bioplastics<br />
Look<strong>in</strong>g further ahead, some of the second<br />
generation bioplastics m<strong>an</strong>ufactur<strong>in</strong>g<br />
technologies under development adopt a "pl<strong>an</strong>t<br />
factory" model <strong>in</strong> which they use genetically<br />
modified (GM) crops or genetically modified<br />
bacteria to optimise efficiency. A ch<strong>an</strong>ge <strong>in</strong> the<br />
consumer perception of GM technology <strong>in</strong> Europe<br />
will be required for these to be widely accepted.<br />
iii. Bio Build<strong>in</strong>g Blocks<br />
Hydrolysis pl<strong>an</strong>ts, based on a r<strong>an</strong>ge of processes,<br />
are already operat<strong>in</strong>g commercially.The Biof<strong>in</strong>e<br />
process, is a commercialised technology that<br />
uses two-step dilute m<strong>in</strong>eral acid hydrolysis to<br />
break down biomass conta<strong>in</strong><strong>in</strong>g lignocellulose<br />
<strong>in</strong>to <strong>in</strong>termediate chemicals that c<strong>an</strong> be further<br />
tr<strong>an</strong>sformed <strong>in</strong>to 2-Methyltetrahydrofur<strong>an</strong> (MeTHF)<br />
<strong>an</strong>d other chemical products. The Biof<strong>in</strong>e process<br />
was developed by BioMetics Inc with fund<strong>in</strong>g<br />
from the United States Department of <strong>Energy</strong>.<br />
A pilot pl<strong>an</strong>t produc<strong>in</strong>g 1 t/day of <strong>in</strong>termediate<br />
chemicals has been operat<strong>in</strong>g <strong>in</strong> South Glens<br />
Falls, New York s<strong>in</strong>ce 1998. The first commercialscale<br />
biomass-based pl<strong>an</strong>t, which produces 10<br />
t/day of levul<strong>in</strong>ic acid from local tobacco bagasse<br />
<strong>an</strong>d paper mill sludge, has been built <strong>in</strong> Caserta,<br />
Italy, by Le Calorie. This started operation <strong>in</strong><br />
2006.<br />
Levul<strong>in</strong>ic acid c<strong>an</strong> be produced <strong>in</strong> yields of up to<br />
70%, or about 0.5 kg per kg of cellulose, along<br />
with formic acid <strong>an</strong>d furfural as valuable by<br />
products. Used for years <strong>in</strong> food, fragr<strong>an</strong>ce, <strong>an</strong>d<br />
specialty chemical applications, levul<strong>in</strong>ic acid is a<br />
precursor for methyltetrahydrofur<strong>an</strong>,<br />
v-valerolactone, <strong>an</strong>d ethyl levul<strong>in</strong>ate, which c<strong>an</strong><br />
all be blended with diesel or gasol<strong>in</strong>e to create<br />
cle<strong>an</strong>er-burn<strong>in</strong>g fuels. Another derivative,<br />
diphenolic acid, is a potential replacement for<br />
bisphenol which is suspected to be <strong>an</strong> endocr<strong>in</strong>e<br />
disrupter.<br />
iv. Wood Board <strong>an</strong>d Eng<strong>in</strong>eered Wood Materials<br />
Wood board materials are made from th<strong>in</strong><br />
sheets (plywood), particles (particle board) <strong>an</strong>d<br />
oriented str<strong>an</strong>d board or fibers (fibreboard).<br />
Eng<strong>in</strong>eered wood <strong>in</strong>cludes a r<strong>an</strong>ge of derivative<br />
wood products which are m<strong>an</strong>ufactured by us<strong>in</strong>g<br />
adhesives to b<strong>in</strong>d together the str<strong>an</strong>ds,<br />
particles, fibers, or veneers of wood to form<br />
composite materials. These products are<br />
eng<strong>in</strong>eered to precise design specifications<br />
which are tested to meet national or<br />
<strong>in</strong>ternational st<strong>an</strong>dards.<br />
Typically, eng<strong>in</strong>eered wood products are made<br />
from the same hardwoods <strong>an</strong>d softwoods that<br />
are used to m<strong>an</strong>ufacture lumber. Sawmill scraps<br />
<strong>an</strong>d other wood waste c<strong>an</strong> be used for<br />
eng<strong>in</strong>eered wood composed of wood particles or<br />
