生物降解塑料是指一类由自然界存在的微生物如细菌、霉菌(真菌)和藻类的作用而引起降解的塑料。理想的生物降解塑料是一种具有优良的使用性能、废弃后可被环境微生物完全分解、更终被无机化而成为自然界中碳素循环的一个组成部分的高分子材料。“  

Biodegradable plastics are a kind of plastics which are degraded by the action of microorganisms such as bacteria, fungi and algae. The ideal biodegradable plastic is a kind of polymer material with excellent performance, which can be completely decomposed by environmental microorganisms after being discarded, and finally be inorganic to become a part of carbon cycle in nature. "
纸”是一种典型的生物降解材料,而“合成塑料”则是典型的高分子材料。因此,生物降解塑料是兼有“纸”和“合成塑料”这两种材料性质的高分子材料。生物降解塑料又可分为完全生物降解塑料和破坏性生物降解塑料两种。
Paper is a typical biodegradable material, while synthetic plastic is a typical polymer material. Therefore, biodegradable plastic is a kind of polymer material with the properties of "paper" and "synthetic plastic". Biodegradable plastics can be divided into complete biodegradable plastics and destructive biodegradable plastics.
破坏性生物降解塑料:破坏性生物降解塑料当前主要包括淀粉改性(或填充)聚乙烯PE、聚丙烯PP、聚氯乙烯PVC、聚苯乙烯PS等。
Destructive biodegradable plastics: at present, destructive biodegradable plastics mainly include starch modified (or filled) PE, PP, PVC, PS, etc.
完全生物降解塑料:完全生物降解塑料主要是由天然高分子(如淀粉、纤维素、甲壳质)或农副产品经微生物发酵或合成具有生物降解性的高分子制得,如热塑性淀粉塑料、脂肪族聚酯、聚乳酸、淀粉/聚乙烯醇等均属这类塑料。
Fully biodegradable plastics: fully biodegradable plastics are mainly made from natural polymers (such as starch, cellulose, chitin) or agricultural and sideline products through microbial fermentation or synthesis of biodegradable polymers, such as thermoplastic starch plastics, aliphatic polyester, polylactic acid, starch / polyvinyl alcohol, etc.
