Biodegradable PLA

In order to decrease human consumption of petroleum, chemists have investigated methods for producing polymers from renewable resources such as biomass. Nature Works polylactic acid (PLA) is a polymer of naturally occurring lactic acid (LA), and LA can be produced from the fermentation of corn. The goal is to eventually manufacture this polymer from waste biomass. Another advantage of PLA is that, unlike most synthetic polymers which litter the landscape and pack landfills, it is biodegradable. PLA can also be easily recycled by conversion back into LA. It can replace many petroleum-based polymers in products such as carpets, bags, cups, and textile fibers. [Pg.181]

Over the past few years, the production of polymers from renewable resources has rapidly increased at the industrial scale. Cargill-Dow has an industrial plant for the production of biodegradable PLA, which has a high-molar mass PRU 00]. Major chemical companies and downstream industries are all preparing for these changes [MAS 06]. [Pg.264]

Starch, cellulose and sugars quickly biodegrade (several days or weeks). (Co)polyesters (PBAT, PBAT-stareh, PHA, PBS, PBSA) biodegrade less easily (several months). However, some materials almost do not biodegrade this is the case for PET, polyolefins (PE, PP) and PVC which take several hundred years to biodegrade. PLA degrades very quickly in compost (several weeks) but a lot longer at room temperature (several years). [Pg.314]
