pla最具大规模产业化优势（PLA the most large-scale industrialization advantages）

pla最具大规模产业化优势（PLA the most large-scale industrialization advantages） PLA: the most large-scale industrialization advantages 6-30 Biodegradation technology has been developed for 30 years, but the proportion of biodegradable materials in the production and utilization of plastic is still very low. Polylactic acid (PLA) as the industrialization of the most mature, the output of the largest and most widely used, the lowest price of the bio based plastics, is the future of the most promising biodegradable petroleum based plastics shake the traditional position, will become the main force of bio based plastics. At present, PLA plastic bags, tableware, golf nails and other products have been circulating in the market, into the tens of thousands of households. Unique advantages of industrialization According to Chen Xuesi, a researcher at the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, PLA materials have many advantages, and they are the most promising materials for large-scale commercial production in bio - based materials in the near future. As the only transparent biological material, PLA can replace traditional plastics in many fields with good performance, and can be composted or buried after waste, and 100% biodegradable into CO2 and water. A general manager of Greater China Zhen Guangming said that the best strategic position in the possession of lactic acid in the metabolic pathway. The theoretical yield of lactic acid produced by microorganisms can reach 100%, so polylactic acid has an obvious cost advantage over other biological materials. It is understood that the current price of PLA is about 20 thousand yuan / ton, cheaper than BASF aliphatic aromatic copolyester products such as Ecoflex and PHA and other biological plastics more than half. According to Zhen Guangming introduction, in 2010, China and foreign countries will have more than 1000 tons of polylactic acid plant operation, PLA industrialization process will speed up. It is
