Biodegradable plastics yuav degrade rau lub sijhawm thiab tig rov qab mus rau hauv cov khoom siv yam tsis muaj kev cuam tshuam ntxiv los ntawm cov tib neeg lossis cov pa oxygen. Piv nrog rau tsiaj plastics-plastics, lub ntsiab sib txawv ntawm cov yas biodegradable thiab petrochemical yas cuam tshuam nrog cov pa roj carbon. Petroleum based plastics tuav cov pa roj carbon monoxide tom qab tsim. Tom qab lawv tau muab pov tseg, cov roj carbon ntawd maj mam tso rov qab rau hauv qhov cua dhau los ntawm kev ua paug lossis yaj yuav tsum tau rov ua dua tshiab. Biodegradable plastics tsis tso cov carbon tawm rov qab rau hauv ib puag ncig tom qab siv. Cov pa roj carbon tsis tau siv nyob rau hauv kev tsim khoom thawj zaug, thiab tsis yog khoom tsim tawm vim tias nws degrades.
Cov kab mob polylactic acids (PLA) yog tsim los ntawm cov kab mob ntoo, cov qos ntoo, kab tsib, los yog pob kws. PLAs yog siv rau hauv kev tsim cov khoom lag luam coob ntawm cov khoom lag luam, xws li kev kho mob cog hniav ntawm pas nrig thiab screws. PLA tseem siv dav nyob hauv kev siv khob ib zaug, ntim khoom noj pov tseg, thiab siv tais diav ib zaug.
