Bio-based plastics are plastics partly produced from biomass. The raw materials are usually provided by plants rich in starch and cellulose such as wood, corn, wheat, sugar cane, vegetable oil, algae or biological waste from households, animal husbandry and food production. Bio-based materials can be procured continuously. This means that use and consumption cannot exceed nature’s ability to reproduce these types of materials. The term "renewable" is slightly different to "bio-based": The term renewable refers to resources of energy, food and stock that are available continuously as nature is able to reproduce them. The term renewable is contrasted with those resources that are based on fossils fuel and thus only possess limited stocks.
