Uko umuryango w’abantu ugenda utera imbere, ubwiyongere bw’ibicuruzwa bya pulasitiki mu buzima bwa buri munsi bw’abantu buri kwiyongera, nk’amasashe ya pulasitiki, amasahani ya pulasitiki, udusanduku twa pulasitiki n’ibindi. Hagati aho, iterambere ry’inganda zitanga ibiribwa ryongereye ubwiyongere bw’ibicuruzwa bya pulasitiki. Ubu bucuruzi kandi bugira ingaruka zikomeye ku bidukikije, kuko ibicuruzwa bya pulasitiki byangiza cyane ibidukikije.
Mu gihe habayeho ibibazo bikomeye by’ibidukikije, gushaka ibindi bisimbura plastiki byabaye ikintu gishimishije ku isi yose. Nyuma y’ubushakashatsi n’ivugurura rihoraho, ibicuruzwa bya PLA byagiye bizamuka buhoro buhoro mu mateka. Ibicuruzwa bya PLA bifite akazi ko kwangirika, bishobora kwangirika burundu mu minsi 90 ku bushyuhe bukwiye n’ibidukikije. Muri icyo gihe, kandi bimara igihe kirekire, bibitswe neza, agasanduku ka PLA n’agasanduku ka PLA n’ibindi bicuruzwa bishobora kubikwa mu gihe kirenze umwaka umwe.
Ibikoresho bishya bya PLA bidafite ingaruka ku bidukikije Amasahani n'ibikoresho byo gupakiramo Inyama z'imbuto Ibiryo
Aside lactic (poly) ifite ubushyuhe bwiza, ubushyuhe bwo gutunganya 170 ~ 230℃, irwanya solvent neza, ishobora gutunganywa mu buryo butandukanye, nko gusohora, kuzunguruka, kunanura biaxial, no gusya inshinge. Uretse kuba ishobora kubora, ibikomoka kuri aside lactic bifite ubushobozi bwo guhuza neza n'ibintu, kugaragara neza, kubonerana, kumva neza no kwihanganira ubushyuhe.
Aside Polylactic (PLA) ni ikintu gishya gishobora kubora gikozwe muri sitashi ikomoka ku bimera bishobora kongera gukoreshwa nk'ibigori. Isukari yavuye muri sitashi binyuze mu gusakaza, hanyuma aside lactic ifite ubuziranenge bwinshi ikarangizwa muri glucose n'ubwoko bumwe na bumwe, hanyuma aside polylactic ifite uburemere runaka bwa molekile ikorwa hakoreshejwe imiti. Ifite ubushobozi bwo kubora neza, kandi ishobora kwangirika burundu na mikorobe mu bidukikije nyuma yo kuyikoresha, amaherezo ikabyara dioxyde de carbone na amazi. Ntiyanduza ibidukikije, ibyo bikaba ingirakamaro cyane mu kurinda ibidukikije, kandi bizwi nk'ibikoresho bitangiza ibidukikije. Uburyo busanzwe bwo gutunganya pulasitiki ni ugutwika, bigatuma imyuka myinshi ihumanya ikirere isukurwa mu kirere, mu gihe aside POLylactic itwikwa mu kwangirika k'ubutaka, dioxyde de carbone ijya mu butaka cyangwa ikayinjizwamo n'ibimera, ntizava mu kirere, ntizizatera ingaruka mbi ku bushyuhe.
Aside poly (lactic acid) ifite akarusho gadasanzwe mu bijyanye n'ibikoresho byo gukoresha mu gihe runaka, ibikoresho byo gupfunyikamo ibiribwa n'ibindi bikoresho byo gukoresha mu gihe runaka kuko ntacyo bitwaye umubiri w'umuntu. Ishobora kwangirika burundu kandi ikujuje ibisabwa ku isi, cyane cyane Umuryango w'Ubumwe bw'u Burayi, Leta Zunze Ubumwe za Amerika n'u Buyapani mu kurengera ibidukikije. Byongeye kandi, nyuma y'iterambere ry'ikoranabuhanga, isoko ryahinduwe n'ibikoresho bya PLA, bishobora gutsinda neza inenge z'agace k'umwimerere, ndetse bimwe na bimwe birwanya ubushyuhe kugeza kuri dogere 120, bishobora gukoreshwa nk'ibikoresho byo mu ifuru ya mikoroonde.
Ariko, ukurikije isoko ririho ubu, ubushobozi bwo gushyushya no kongera ubushyuhe bw'ibicuruzwa bya PLA ntabwo bugereranywa n'ibindi bicuruzwa bishobora kwangirika, ariko igiciro cy'ibicuruzwa bya PLA kiri hejuru ugereranyije n'ibindi bicuruzwa bishobora kwangirika. Abantu benshi bahitamo kuba ibiryo bishobora kwangirika, ariko kuba ibiryo bishobora kwangirika bikura amavuta, bigakurura amazi, kandi bikagira ingaruka ku bicuruzwa bipfunyitse. Nanone kandi, amapaleti ya babase ashobora kwangirika iyo adahagije.
