Bioplastic A bioplastic is a polymer structure based on processed biological materials rather than petrochemicals. Bioplastics are commonly made from renewable sources like starch, vegetable oil, and less commonly, chicken feathers. The idea behind bioplastic is to create a plastic that has the ability to biodegrade.[11] Bisphenol A (BPA): BPA is a synthetic compound that serves as a raw material in the manufacturing of such plastics as polycarbonates and epoxy resins.
