Composting

Composting is a new method of recovery for compostable plastics like NatureWorks® biopolymer (PLA – polylactic acid). NatureWorks® biopolymer is currently used to produce everyday packaging, food serviceware, fiber and plastic consumer items. Derived from a 100% annually renewable resource found in natural plant sugars, NatureWorks biopolymer offers a more sustainable solution as a material choice.

Global regulatory guidelines and standards for composting of plastics revolve around four basic criteria: material characteristics, biodegradation, disintegration and ecotoxicity (compost quality). In the United States, all required testing data for NatureWorks® biopolymer has been independently reviewed by the Biodegradable Products Institute (BPI) for certification according to ASTM 6400-99.

NatureWorks® biopolymer is listed on the BPI positive list for compostable materials. End products made with 100% NatureWorks® biopolymer will compost in municipal/industrial facilities according to ISO, ASTM, and EN regulations.  The number of these facilities are limited and may not be available near you.
