生物（wù）降解顆粒在生產後可分類哪些類型？
生物降解塑料是指一（yī）類（lèi）由自然界存在的微生物如細菌、黴菌（真菌）和藻類的作用而引起降解的塑料。理想的生物降解塑料是一種具有（yǒu）優良的使用性（xìng）能、廢棄後可被環境微生物完全（quán）分解（jiě）、Z終被無機化而成為自然界（jiè）中碳素循環的一個組成部分的高分子材料。“紙”是一種典型的生物降解材料，而“合成塑料”則是典（diǎn）型的高分子材料。因（yīn）此，生物降解塑料是兼（jiān）有“紙”和“合成塑料”這兩種材料性質的高分子材料。
Biodegradable plastics refer to a class of plastics that are degraded by the action of naturally occurring microorganisms such as bacteria, molds (fungi), and algae. The ideal biodegradable plastic is a polymer material with excellent performance, which can be completely decomposed by environmental microorganisms after being discarded, and Z is eventually inorganic to become a component of the carbon cycle in nature. "Paper" is a typical biodegradable material, while "synthetic plastic" is a typical polymer material. Therefore, biodegradable plastics are polymer materials that have both the properties of "paper" and "synthetic plastics".
生物降解（jiě）塑料又稱生物分（fèn）解塑料，指在自然界如土壤和/或沙土等條（tiáo）件下，和/或特（tè）定條件如堆肥化條（tiáo）件下或厭氧消化條件下（xià）或水性培養液中，由自然（rán）界存在的微生物作用引起降解，並Z終完全降解變成二氧化碳（CO? ）或/和甲烷（wán）（CH?）、水（H?O）及其所含（hán）元素（sù）的礦化無機鹽以及（jí）新的生物質的塑料。
Biodegradable plastics, also known as biodegradable plastics, refer to plastics that are degraded by natural microorganisms under natural conditions such as soil and/or sandy soil, and/or specific conditions such as composting or anaerobic digestion, or in aqueous culture solutions, and ultimately completely degrade into carbon dioxide (CO?) or/and methane (CH?), water (H? O), and mineralized inorganic salts of the elements contained therein, as well as new biomass.
按原料成（chéng）分來源分類，生物降解塑料可分為生物基生物降解塑料及石化基生物降解塑料兩類。
According to the source classification of raw materials, biodegradable plastics can be divided into two categories: bio-based biodegradable plastics and petrochemicals based biodegradable plastics.
生物基生物降解塑料主要可分為（wéi）四類：一類為天然（rán）材料直接加工得到的塑料；第二類為微生物（wù）發酵和化學合成共同參與得（dé）到的聚合物；第三類為由微生物直接合成的聚合物；第四類為（wéi）以上這些材料共混加工得到（dào）的或這些材料和其他化學合成（chéng）的（de）生（shēng）物（wù）降解塑料共混加工得到的（de）生物降解塑料。
Biodegradable plastics based on biological materials can be divided into four categories: one is plastics directly processed from natural materials; The second category is polymers obtained through microbial fermentation and chemical synthesis; The third category is polymers directly synthesized by microorganisms; The fourth category is biodegradable plastics obtained by blending these materials or by blending these materials with other chemically synthesized biodegradable plastics.
石化基生物降解塑料是指以化學合成的（de）方法將石化產品單（dān）體聚合而得的塑料，如PBAT、聚丁 二酸丁二（èr）醇酯（PBS）、二氧化碳（tàn）共聚物（wù）（PPC）等。
Petrochemical based biodegradable plastics refer to plastics obtained by polymerization of petrochemical product monomers using chemical synthesis methods, such as PBAT, polybutylene succinate (PBS), carbon dioxide copolymer (PPC), etc.
