I-Polylactic acid (PLA) iyinto entsha ebolayo, eyenziwe ngezinto ezingavuthiwe zesitashi ezihlongozwe izinsiza zezitshalo ezivuselelekayo (njengommbila). I-glucose itholakala ku-starch impahla eluhlaza ngokusebenzisa i-saccharification, bese i-lactic acid ene-high-purity ikhiqizwa ngokuvutshelwa kwe-glucose namagciwane athile, bese i-polylactic acid enesisindo esithile samangqamuzana ihlanganiswa ngendlela yamakhemikhali.
Ine-biodegradability enhle. Ngemuva kokusetshenziswa, kungonakalisa ngokuphelele ama-microorganisms emvelweni, futhi ekugcineni kukhiqize i-carbon dioxide namanzi, okungangcolisi imvelo, okuzuzisa kakhulu ekuvikelweni kwemvelo. Kubhekwa njengento evumelana nemvelo.
Indlela yokwelapha yamapulasitiki ajwayelekile isashiswa kanye nokushiswa kwesidumbu, okuholela ekutheni inani elikhulu lamagesi abamba ukushisa akhishelwe emoyeni, kuyilapho amapulasitiki e-polylactic acid engcwatshwa enhlabathini ukuze acekelwe phansi, futhi isikhutha esikhiqiziwe singena ngqo enhlabathini noma i-organic matter. amuncwa izitshalo, ezingeke zikhishwe emoyeni futhi ngeke zibangele umphumela we-greenhouse.
