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.
The mankhwala njira mapulasitiki wamba akadali incineration ndi kutentha mtembo, chifukwa mu kuchuluka kwa mpweya wowonjezera kutentha kutulutsidwa mu mlengalenga, pamene polylactic asidi mapulasitiki m'manda m'nthaka kuwonongeka, ndi kwaiye mpweya woipa amalowa mwachindunji nthaka organic kanthu kapena ndi kutengeka ndi zomera, zomwe sizidzatulutsidwa mumlengalenga ndipo sizimayambitsa kutentha kwa thupi.
