Bioplastics are plastics that are bio-based (made from a renewable resource, like vegetables), biodegradable (able to break down naturally) or a combination of both. Bioplastics help to reduce our reliance on fossil fuels for plastic production and can be made from corn, soybeans, wood, used cooking oil, algae, sugarcane and more. One of the most commonly used bioplastics in packaging is PLA.
