I-Polylactic acid (PLA) iyisikhwama sepulasitiki esisha esibolayo esenziwe ngesitashi esikhishwe ezinsizeni zezitshalo ezivuselelekayo njengommbila.Ine-biodegradability enhle futhi ingacekelwa phansi ngokuphelele ama-microorganisms emvelweni ngemva kokusetshenziswa, ekugcineni ikhiqize i-carbon dioxide namanzi.Ayingcolisi imvelo, izuzisa kakhulu ekuvikelweni kwemvelo, ibhekwa njengempahla yokuvikela imvelo
Esikhwameni sepulasitiki esingaboli, i-polylactic acid (i-PLA) yaziwa njengenye yezinhlobonhlobo ezinamandla amakhulu okuthuthuka, nokuvumelana kwe-bio, ukubola kanye nekhono lokuvuselela izinsiza.Endaweni yemvelo, imfucuza ye-PLA ingehliswa ibe yi-CO2 ne-H2O ngochungechunge lwezinqubo ze-biological metabolic ezifana ne-hydrolysis (izinyanga ezingu-6-12).Le CO2 kanye ne-H2O ingasetshenziswa izitshalo ukukhiqiza isitashi ngesikhathi se-photosynthesis, engasetshenziswa ukukhiqiza i-polylactic acid futhi.Ngakho-ke, i-Polylactic acid ayiyona nje into engapheli, kodwa futhi inganciphisa ukungcola okumhlophe, isindise izinsiza zikawoyela, futhi iyinto engagcina "ibhalansi ye-carbon cycle" emvelweni.
Isikhathi esiqondile esisithathayo ukuze isikhwama esigaywe kabusha se-biodegradable sibole sincike ezintweni ezihlukahlukene, njengezinga lokushisa kanye nenani lomswakama.Izikhwama ezivundisiwe zingakwazi ukubola zingakapheli izinsuku ezingama-30 ezikhungweni zokwenza umquba wokuthengisa futhi zingakapheli izinsuku ezingama-90 ezinhlelweni zokuvundisa ekhaya.
Njengamanje sikhiqiza: izikhwama zekhofi ezingaboli, izikhwama zetiye ezingaboli.Izikhwama ezibolayo ezinezicaba, izikhwama ezigayiwe ezingaboli, ezipakishwayo zokudla ezingaboli, isikhwama soziphu esingaboli, esingaboli kahle esinezinhlangothi ezi-3 njll, imikhiqizo yethu idayisa amazwe angaphezu kuka-20 emhlabeni jikelele, maningi kakhulu amakesi namasampula, uma unawo. isidingo sezikhwama ezibolayo, sicela usithinte, sizokunikeza izixazululo eziphelele kakhulu zokupakisha, Vumela imikhiqizo yakho ibe nokuthengisa okungcono.Futhi usebenze nathi ukuvikela umhlaba.
