Examples of bioplastic polymers are polylactic acid (PLA), polycaprolactone (PCL), polyhydroxybutyrate-covalerate (PHBV), and polyesteramide. They can be made from plants such as canola, soybean, corn and potatoes. Like biomass plastics, bioplastics can also be made from wastes of the food industry, making food production processes more sustainable. Bioplastics are also used to make many different commercial products. Because they eventually degrade, the biopolymers used to make bioplastics have a special role in medicine, as they are used to make sutures (eg. polyesteramide).
