Polylactic acid (PLA) ndi chinthu chatsopano chomwe chimatha kuwonongeka, chomwe chimapangidwa ndi zopangira zowuma zomwe zimaperekedwa ndi zomera zongowonjezedwanso (monga chimanga). Glucose amatengedwa kuchokera ku wowuma zopangira kudzera pa saccharification, ndiyeno lactic acid yoyera kwambiri imapangidwa ndi nayonso mphamvu ya shuga ndi mabakiteriya ena, kenako polylactic acid yokhala ndi kulemera kwina kwa maselo amapangidwa ndi njira yopangira mankhwala.
Ili ndi biodegradability yabwino. Pambuyo ntchito, zikhoza kuonongeka kotheratu ndi tizilombo m'chilengedwe, ndipo potsiriza kutulutsa mpweya woipa ndi madzi, amene saipitsa chilengedwe, amene ali opindulitsa kwambiri kuteteza chilengedwe. Imazindikiridwa ngati zinthu zokomera chilengedwe.
Njira zochizira mapulasitiki wamba akadali kutentha ndi kutentha, zomwe zimapangitsa kuti mpweya wambiri wowonjezera kutentha utuluke mumlengalenga, pomwe mapulasitiki a polylactic acid amakwiriridwa m'nthaka kuti awonongeke, ndipo mpweya wopangidwa ndi kaboni dayokisaidi umalowa mwachindunji m'nthaka kapena kutengeka ndi zomera, zomwe sizidzatulutsidwa mumlengalenga ndipo sizimayambitsa wowonjezera kutentha.
