Bioplastic can be made from agricultural by-products and also from used plastic bottles and other containers using microorganisms. Some, but not all, bioplastics are designed to biodegrade. Biodegradable bioplastics can break down in either anaerobic or aerobic environments, depending on how they are manufactured.

Bioplastics can be composed of starches, cellulose, biopolymers, and a variety of other materials. Note 3: The use of the term “bioplastic” is discouraged.
