With the rising energy prices and ecological and environmental problems, the pace of bio-dissolved biomaterials replacing traditional petroleum products shows a gradually accelerating development trend around the world. It is expected that government agencies will also implement corresponding preferential policies and related policies. Relevant laws and regulations encourage application fields, and the large-scale application prospects of bio-melting materials are very optimistic.Bio-melting materials include biotechnologically manufactured high-polymer materials such as polyhydroxyalkanoates; biotechnologically manufactured raw materials such as polylactic acid, polybutylene succinate, and polysaccharides; in addition, some starch-based biological Degradable plastics, carbon dioxide prepolymer alicyclic polypropylene, etc.Starch-based biodegradable plastic is an injection molding product produced by blending starch with other polymers after undergoing modified materials and thermal polymerization. It can replace general plastic raw materials in industrial production and can be used as packaging materials. , Seismic grade materials, agricultural films, food packaging materials, toys, etc. PLAIt is a polymer material material that is aggregated and converted from lactic acid bacteria beverage as raw material. It has the characteristics of non-toxicity, high tensile strength, easy processing and high-quality biocompatibility, etc. The product can be melted after use. Therefore,PLAIt is a bio-ecological environmental protection material that can truly guarantee the dual effects of ecological environmental protection and social and economic development.Butylene succinate is obtained from succinic acid and butanediol according to the shrinkage reaction, and is now recognized as a biodegradable plastic with good comprehensive performance. becausePBSExcellent comprehensive performance, high cost performance and reasonable, wide range of applications, can be used in packaging, kitchen supplies, cosmetic bottles and medicine bottles, agricultural machinery plastic film, organic fertilizer and organic fertilizer initial coagulation materials, biological diagnosis and treatment polymer materials and other fields .Polyhydroxyalkanoates are high molecular polyesters, which are intracellular polyesters produced by many pathogenic bacteria under special circumstances. Currently more than90genus of pathogens were found to transform into more than150more than one structurePHA. already commercializedPHAThe main products are polyhydroxybutyric acid, prepolymer of hydroxybutyric acid and hydroxyvaleric acid, and prepolymer of hydroxybutyric acid and hydroxycaproic acid.
