Bioplastics are not a single kind of plastic, but rather a family of materials that vary considerably from one another.
Bioplastics in general are partially or completely based on natural resources. The biomass used for biobased plastics today comes mostly from grain (corn), sugar cane, potatoes or castor oil. Other natural resources, such as cellulose and crop residues (corn stover, straw) will grow more important in the future.
