In the report “Biodegradable Polylactic Acid and Membrane from Corn†published by the Eldib Engineering and Research Corporation of the United States, several large Japanese companies were reported to actively implement the industrialization of polylactic acid (PLA) from corn and further production of plastics. Process, product application packaging film, fiber and a variety of injection products.
At present, global plastic production is about 124 million tons, of which about 231,000 tons can be replaced with PlA and other biodegradable plastics, less than 0.2% of the total. Biodegradable plastics come from two sources: one is Cargill's PLA and thermoplastic starch and its blends are renewable resources; the other is from oil and gas synthesis, such as Eastman Chemical Copolyester with DuPont. Recently, the price of natural gas in the world has risen sharply, so more consideration will be given to the production of biodegradable plastics from petroleum development. â—†
