What is "natureworks"

NatureWorks LLC is a U.S. company that manufactures bioplastics— polymers derived entirely from plant resources—as an alternative to conventional plastic, which is made from petroleum. The commercial quality polymer is made from the carbon found in simple plant sugars such as corn starch to create a proprietary polylactic acid polymer (PLA) which is marketed under the brand name Ingeo. Headquartered in Minnetonka, Minnesota, NatureWorks is jointly owned by Cargill and PTT Global Chemical, a Thai state-owned company.
