I-Polylactic acid (PLA) yinto entsha enokubola, eyenziwe nge-starch ekrwada ecetywayo yimithombo yezityalo ezivuselelekayo (ezifana nombona).I-glucose ifumaneka kwi-starch material ekrwada nge-saccharification, kwaye emva koko i-acid ye-lactic ephezulu iveliswa ngokubiliswa kwe-glucose kunye neebhaktheriya ezithile, kwaye emva koko i-polylactic acid enobunzima obuthile bemolekyuli idityaniswe yindlela yokudibanisa imichiza.
Inokonakala kwezinto eziphilayo.Emva kokusetyenziswa, inokutshatyalaliswa ngokupheleleyo yi-microorganisms kwindalo, kwaye ekugqibeleni ivelise i-carbon dioxide kunye namanzi, engayingcolisi indalo, enenzuzo kakhulu ekukhuselweni kwendalo.Yamkelwa njengesixhobo esivumelana nokusingqongileyo.
Indlela yonyango yeeplastiki eziqhelekileyo isatshisa kunye nokutshisa, okukhokelela kwinani elikhulu leegesi ze-greenhouse ezikhutshwa emoyeni, ngelixa iiplastiki ze-polylactic acid zingcwatyelwa emhlabeni ukuze zithotywe, kwaye i-carbon dioxide eveliswayo ingena ngokuthe ngqo kumhlaba we-organic or is. ukufunxwa zizityalo, ezingayi kukhutshwa emoyeni kwaye aziyi kubangela i-greenhouse effect.
