Plastic decomposition

    Recent studies have highlighted several types of plastics that can be decomposed by bacteria.  One notable example is thermoplastic polyurethane, which has been developed to include bacterial spores that help it break down when exposed to compost conditions.  Another type is polyhydroxyalkanoates, which are produced by bacteria and degrade naturally in various environments, including compost, soil, and water.
