Would you mind providing some links to these biodegradeable plastics? The last time I checked bio-degradeable plastic was nothing more than a marketing sleight of hand: Essentially just micro plastic bound together with something biodegradeable like corn starch. The plastic still enters the environment, skips the part where it breaks down from large pieces to tiny ones, yet still contaminates the enviroment.
