The resulting bioplastics are chemically identical to their fossil counterparts. įor some plastics, the same polymer chains can be made from renewable sources. "There are a lot of bioplastics or materials that are called bioplastics that are not biodegradable," says Constance Ißbrücker, head of environmental affairs at the industry association European Bioplastics. And even biodegradable plastics might not biodegrade in every environment. Not all bio-based plastics are biodegradable, and not all biodegradable plastics are bio-based. The term "bioplastics" is actually used for two things: bio-based plastics (plastics made at least partly from biological matter) and biodegradable plastics (plastics that can be completely broken down by microbes in a reasonable timeframe, given specific conditions). Have you ever stood in front of a supermarket shelf and wondered if you should buy that product made from bioplastics rather than the conventional kind? Many people assume all bioplastics are made from plants and can break down completely in the environment.
