Bioplastics are biopolymers, derived from renewable biomass sources such as corn starch or vegetable oil. Polyactic acid (PLA) is one form of bioplastic, produced from glucose.
Bio-based plastics are often touted as “biodegradable.” But this term has several stipulations behind it. While these products may in fact have components that are capable of degrading, this process only occurs under specific conditions and biodegradable plastics cannot be composted in a backyard compost pile. Because the material requires very high heat, these plastics can only degrade in a commercial composting facility.
