Corn-based plastic

Polylactic acid (PLA), a plastic substitute made from fermented plant starch (usually corn), is quickly becoming a popular alternative to traditional petroleum-based plastics.

Polylactic acid or polylactide (PLA) is a biodegradable, thermoplastic, aliphatic polyester derived from renewable resources, such as corn starch (in the U.S.) or sugarcanes (rest of world).

NatureWorks LLC (formerly Cargill, Inc.) is the main source for PLA corn-resin pellets
