Description
A biodegradable a thermoplactic polyester made from renewable resources, such as corn starch, cassava roots, or surgarcane. Polylactic acid was first developed in the 1980s in Japan. By 2010 it was the second most used bioplastic in the world. Polylactic acid is made by the polymerization of lactic acid and the ester lactide. The resultant polyester can be formed into fibers, sheets, and molded products. Early uses included absorbable sutures and dissolvable medical implants, but the product quickly expanded into the area of biodegradable consumer products such as cups, bottles, bags, and containers. It is also used for 3d printing.
