PCR, post consumer recycled resin, is made by plastic products. By collecting plastic products and remaking them into resins for plastic industries to manufacture new products. With the recycling system, many environment issues can be solved.
Polylactic acid(PLA) is a thermoplastic aliphatic polyester. The lactic acid or lactide required for the production of polylactic acid can be obtained by fermentation, dehydration and purification of renewable resources. The polylactic acid obtained generally has good mechanical and processing properties, and the polylactic acid products can be rapidly degraded in various ways after being discarded.
