Diemen, the Netherlands – 8 September 2008 – CSM nv subsidiary PURAC and Sulzer Chemtech have jointly
developed a new cost effective polymerization process to produce high quality Poly-Lactic Acid (PLA). The
new process relies upon proprietary and jointly developed polymerization and devolatilization technology to
efficiently produce a range of PLA products from the specialty Lactides supplied by PURAC. PURAC and
Sulzer Chemtec signed a joint cooperation agreement for the development and sharing of this technology.
Poly-Lactic Acid is a bioplastic made from biorenewable raw materials like carbo-hydrates. PURAC offers
the lactide monomers as polymerization feedstock and in cooperation with Sulzer the polymerization
technology to make PLA.
This offering will significantly reduce the process and product development time thereby enabling faster and
more reliable market entry for PLA producers. The new process requires substantially less investment and
has unmatched potential for economic scale-up to high volumes.
The first plant to use this new technology will be built by Synbra in the Netherlands for the production of
BIOFOAM®, a foamed product made from this PLA, complementary to their wide range of polystyrene foam products offered today. The new plant with a capacity of 5,000 ton/year is targeted to be operational by
the end of 2009. Synbra intends to assume a leading position in Europe as supplier of biologically degradable
polymers from renewable sources and plans to expand the PLA capacity to 50,000 ton/year.
By the end of 2008, a demonstration and product development plant will be available exclusively to partners
of PURAC, to facilitate both product and process development to meet various application and customer
demands. The demonstration plant will be located at Sulzer Chemtec in Winterthur, Switzerland.
