Cheaper, greener, route to bioplastic

http://www.tanmarket.com - Cheaper, greener, route to bioplastic INTRO: Belgian chemists have discovered a cheaper, cleaner, way of making polylactic acid (PLA). Their invention is to be developed by a petrochemical company. SHOWS: COSTA MESA, CALIFORNIA, UNITED STATES (FILE) (REUTERS - ACCESS ALL) 1. PLASTIC PELLETS BEING MADE 2.

Our process runs about 100 degrees centigrade lower in temperature and our productivities, which is kind of how much product can you make per volume of reactor per hour are much higher and our product is also much cleaner, so we don't make side products, for instance, caused by racemisation or other side reactions because we work at a lower temperature." 6.

(SOUNDBITE) (English) MICHIEL DUSSELIER, RESEARCHER AT UNIVERSITY OF LEUVEN, SAYING: "Our process is based on condensation reaction in which we will contact lactic acid with a zeolite and zeolites are famous catalysts from refinery and petrochemical industry, and these catalysts are micro porous materials - sort of nano sponges - so they have a huge internal surfaces and they also have limited space inside their voids, so it's kind of a reactive sponge." 11.

PLASTIC PENS STORY: Polylactic acid (PLA) plastic is an increasingly common, environmentally friendly, alternative to conventional petrochemical-based mass plastics. But it's a costly process. Researchers at the University of Leuven's Centre for Surface Chemistry and Catalysis have published research in the journal Science that suggests a new method of simplifying the PLA production process and making it waste-free. According to lead researcher Michiel Dusselier: "Instead of (the current) two-step process currently, it's a one-step process. Our process runs about 100 degrees centigrade lower in temperature and our productivities, which is kind of how much product can you make per volume of reactor per hour are much higher and our product is also much cleaner, so we don't make side products, for instance, caused by racemisation or other side reactions because we work at a lower temperature." Supervising professor Bert Sels expects the new patented method to be an industrial game-changer. "The impact, I think, will be very great in the sense that we now have a very competitive process, where there is a monopoly at the moment," said Sels. "I think there will now be much more players in the market giving you the product at much lower prices and I think this will maybe really be the start of the PLA into the bio-plastic business."
