Abstract Plastics play an important role as a result of their many applications such as packaging, building materials and commodity as well as hygienic products. However, because of their persistence in the environment, the increased costs of solid waste disposal waste disposal due to the reductions in available landfill space as well as the potential hazards from waste incineration, polymers became a waste deposit problem. Thus, biodegradable as a potential partial solution of these problems were developed during the last decade. The bacterial polyesters, p(3HB) as well as its copolymers p (3HB-co-10%HV) possess properties similar to petrochemical based thermoplastics and are completely degradable and also compatible. |
