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 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 thaum pib tsim khoom, thiab isn'
Polybutylene succinate (PBS) yog aliphatic polyester nrog cov yam ntxwv piv nrog polypropylene. Ib qho kev sib txawv loj yog PBS yuav thim tawm lub ntuj thiab ua rau dej thiab CO2 tau tshaj tawm rau hauv ib puag ncig. PBS yog tsim los ntawm succinic acid, uas yog cov tshuaj lom neeg organic rau cov muaj sia nyob ntau yam. PBS nquag siv hauv cov zaub mov ntim khoom, ntim khoom rau cov khoom lag luam kom zoo nkauj, kev kho mob, thiab yaj tshuaj tuaj yeem hloov kho. PBS feem ntau kuj tau sib xyaw nrog Polyactic acids (PLAs) txhawm rau hloov cov yam ntxwv ntsig txog qhov muaj zog thiab cuam tshuam tsis hloov pauv hloov rau cov yam ntxwv ntawm thermal lossis tensile.
