"Kubaho karubone nkeya" byahindutse ingingo nyamukuru mugihe gishya.Mu myaka yashize, kurengera ibidukikije, kubungabunga ingufu, no kugabanya ibyuka bihumanya ikirere byinjiye buhoro buhoro mu cyerekezo cy’abaturage, kandi na byo byabaye inzira nshya ishyigikiwe kandi igenda ikundwa muri sosiyete.Mugihe cyicyatsi na karubone nkeya, ikoreshwa ryibicuruzwa byangirika bifatwa nkikimenyetso cyingenzi cyubuzima buke bwa karubone, kandi cyubahwa cyane kandi kigakwirakwizwa.

Hamwe no kwihuta k'umuvuduko w'ubuzima, udusanduku twa sasita twa pulasitike twa pulasitike, imifuka ya pulasitike, amacupa, ibikombe by'amazi n'ibindi bintu byabaye hose mu buzima.Bitandukanye nimpapuro, imyenda nibindi bikoresho, ibicuruzwa bya pulasitike birajugunywa muri kamere kandi bigoye guteshwa agaciro.Mugihe bizana ubuzima bwabantu, gukoresha cyane birashobora no gutera "umwanda wera".Ni muri urwo rwego, ibinyabuzima byangiza ibinyabuzima byagaragaye.Ibikoresho bishobora kwangirika ni ibintu bigenda bigaragara bifite inyungu zikomeye mubijyanye n’imikorere y’ibidukikije ugereranije n’ibicuruzwa gakondo byajugunywe.Ibicuruzwa byakozwe hifashishijwe ibinyabuzima bishobora kwangirika nkibikoresho fatizo bifite umwanya munini wamasoko kandi bigahinduka ikintu cyingenzi cyimyumvire yubuzima bwa karubone nkeya.

Hariho ubwoko bwinshi bwibikoresho bishobora kwangirika, harimoPCL, PBS, PBAT, PBSA, PHA,PLGA, PLA, nibindi Uyu munsi tuzibanda kubintu bigaragara biodegradable material PLA.

PLA, bizwi kandi nkaacid, CAS 26023-30-3ni ibikoresho fatizo bya krahisi byasembuwe kugirango bitange aside ya lactique, hanyuma igahinduka aside polylactique ikoresheje synthesis ya chimique kandi ikagira ibinyabuzima byiza.Nyuma yo kuyikoresha, irashobora kwangizwa rwose na mikorobe miterere yabantu, amaherezo ikabyara karuboni n'amazi bitanduye ibidukikije.Ibidukikije ni byiza cyane, kandi PLA izwi nkibikoresho bitangiza ibidukikije bifite imiterere y’ibinyabuzima nziza.

Ibikoresho nyamukuru bya PLA ni fibre yibihingwa, ibigori nibindi bicuruzwa byubuhinzi n’uruhande, kandi PLA nishami ryingenzi ryibinyabuzima bigenda byangirika.PLA ifite imitungo idasanzwe mubijyanye no gukomera no gukorera mu mucyo.Ifite biocompatibilité ikomeye, porogaramu yagutse, imiterere ikomeye yumubiri nubukanishi, kandi yujuje ibisabwa bitandukanye.Irashobora gukoreshwa muburyo butandukanye bwo kubyara umusaruro munini, hamwe na antibacterial igipimo cya 99.9%, bigatuma iba ibintu byangirika cyane.

Acide polylactique (PLA)ni ikintu gishya cyangiza ibidukikije kandi kibisi kibora ibinyabuzima biva muri acide lactique nkibikoresho fatizo;Mu myaka yashize, PLA yakoreshejwe mubicuruzwa nimirima nkibyatsi, ibikoresho byo kumeza, ibikoresho byo gupakira firime, fibre, ibitambara, ibikoresho byo gucapa 3D, nibindi. PLA nayo ifite imbaraga ziterambere cyane mubice nkibikoresho byubuvuzi, ibice byimodoka, ubuhinzi , amashyamba, no kurengera ibidukikije.

PLA yakozwe naIngandani ntangarugero muri acide polylactique yose "agace".Binyuze mu gutoranya cyane ibikoresho fatizo bya aside irike ya polylactique, plastike ya PLA polylactique na fibre ya PLA polylactique ikoreshwa mugutanga umusaruro mwiza, wangiza uruhu, ubuziranenge, kandi bukomeye bwa peteroli ya antibacterial ishingiye kuri plastike.Ibicuruzwa byayo byingenzi birimo imyenda igezweho, inkweto n'ingofero, ibikoresho byo kumeza, ibikombe n'amasafuriya, ibikoresho byo mu gikapu, ibikinisho, imyenda yo mu rugo, gufunga imyenda n'amapantaro, ibikoresho byo mu rugo, guhanagura no guhanagura, hamwe n'indi mirima ifitanye isano rya bugufi n'ubuzima bwacu bwa buri munsi.

Kugaragara kwaPLAIrashobora gufasha abantu kwirinda umwanda wera, kugabanya kwangirika kwa plastike, no guteza imbere kumenya neza impinga ya karubone no kutabogama kwa karubone.Intego y'inganda Unilong ni "kugendana n'umuvuduko w'ibihe, kuyobora ubuzima bwangiza ibidukikije", guteza imbere cyane ibicuruzwa byangiza ibidukikije, gutuma abantu barya ubuzima bwiza kandi bakagira ubuzima buzira umuze, reka ibinyabuzima byinjira mu ngo ibihumbi, bikayobora inzira nshya icyatsi na karubone ubuzima, kandi byuzuye byinjira mubuzima buke bwa karubone.
