Biodegradable plastics are plastics that decompose by the action of living organisms, usually bacteria. Two basic classes of biodegradable plastics exist: Bioplastics, whose components are derived from renewable raw materials and plastics made from petrochemicals containing biodegradable additives which enhance biodegradation. == Examples of biodegradable plastics == * While aromatic polyesters are almost totally resistant to microbial attack, most aliphatic polyesters are biodegradable due to their potentially hydrolysable ester bonds: * * Naturally Produced: Polyhydroxyalkanoates (PHAs) like the poly-3-hydroxybutyrate (PHB), polyhydroxyvalerate (PHV) and polyhydroxyhexanoate (PHH); * * Renewable Resource: Polylactic acid (PLA); * * Synthetic: Polybutylene succinate (PBS), polycaprolactone (PCL)... * Polyanhydrides * Polyvinyl alcohol * Most of the starch derivatives * Cellulose esters like cellulose acetate and nitrocellulose and their derivatives (celluloid). * Enhanced biodegradable plastic with additives.〔(【引用サイトリンク】title=Biodegradable plastic and additives. )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「biodegradable plastic」の詳細全文を読む スポンサード リンク
