Biobased plastics are made in whole or in part from renewable sources such as corn, potato skins, sugar cane, PLA, Bio PE, and nylon.
According to the U.S. Federal Trade Commission, a plastic can only be labeled as biobased if it meets the ASTM D6866 standard, which is the standard test method for determining the biobased content of a solid, liquid, or gaseous sample using radiocarbon analysis. Similar standards are in effect in other regions of the world.
