With the rise of energy prices and the increasingly prominent environmental problems, the pace of replacing traditional petroleum products with biodegradable biomaterials is gradually accelerating in the world. It is hoped that the government will issue relevant preferential policies, laws and regulations to encourage market application. The prospect of large-scale application of biodegradable materials is very optimistic.
Biodegradable materials include polymer materials directly prepared by biotechnology, such as polyhydroxyfatty acid esters (PHA). A class of materials prepared and polymerized by biotechnology, such as polylactic acid, PBS, polyamino acid, etc. In addition, starch based biodegradable plastics, carbon dioxide copolymer aliphatic polycarbonate (APC), etc.
Starch based biodegradable plastic is a kind of plastic product which is made of starch and other polymer by modification and grafting reaction. It can be used as packing material, shockproof material, plastic film, food container, toy, etc.
PLA lactic acid is polymerized as raw material to produce polymer material, which is non-toxic, non irritant, high strength, easy to process, shaping and good biocompatibility. The product can be completely degraded after use. Therefore, PLA is a kind of bio environmental protection material that can truly achieve ecological and economic impact, and is the most active and fastest-growing biodegradable plastic developed in recent years.
Polybutylene glycol succinate is a kind of biodegradable plastics with the best comprehensive properties. PBS is widely used in packaging, tableware, cosmetics, medicine bottles, disposable medical supplies, agricultural films, pesticide and chemical fertilizer slow-release materials, biomedical polymer materials and other fields due to its excellent comprehensive performance and reasonable cost performance.
Polyhydroxy fatty acid ester is a kind of intracellular polyester synthesized by a variety of bacteria under specific conditions. More than 90 genera of bacteria can synthesize more than 150 different forms of PHA. At present, the main commercial PHA products are PHB, PHBV and PHBHHx.
