Polylactic acid (PLA) ndi chinthu chatsopano chomwe chimawola, chomwe chimapangidwa ndi zinthu zopangira starch zomwe zimapangidwa ndi zomera zongowonjezedwanso (monga chimanga). Shuga amapezeka kuchokera ku zinthu zopangira starch kudzera mu saccharification, kenako lactic acid yoyera kwambiri imapangidwa ndi kuwiritsa shuga ndi mabakiteriya ena, kenako polylactic acid yokhala ndi kulemera kwina kwa mamolekyu imapangidwa pogwiritsa ntchito njira yopangira mankhwala.
Ili ndi mphamvu yabwino yowola. Ikagwiritsidwa ntchito, imatha kuwonongeka kwathunthu ndi tizilombo toyambitsa matenda m'chilengedwe, ndipo pamapeto pake imapanga mpweya woipa ndi madzi, zomwe sizimaipitsa chilengedwe, zomwe zimathandiza kwambiri kuteteza chilengedwe. Imadziwika kuti ndi chinthu choteteza chilengedwe.
Njira yochiritsira mapulasitiki wamba ndiyo kuyatsa ndi kutentha thupi, zomwe zimapangitsa kuti mpweya wambiri wowonjezera kutentha utuluke mumlengalenga, pomwe mapulasitiki a polylactic acid amakwiriridwa m'nthaka kuti awonongeke, ndipo mpweya wa carbon dioxide wopangidwa umalowa mwachindunji mu nthaka kapena umatengedwa ndi zomera, zomwe sizidzatulutsidwa mumlengalenga ndipo sizingayambitse kutentha kwa dziko.
