Natural plastics are Rubber is a natural occurring polymer. The problems associated with plastics - For years we've filled our landfills with plastics and storage containers that will, in essence, sit and not rot. The scientific word for "rotting" is biodegradation, the process by which organic materials are broken down by other living things. Name one positive move that supermarkets and chains stores have done to reduce the use of plastics These applesauce cups are made out of cornstarch, which means they can biodegrade in soil, compost or waste-treatment facilities within a few months.
