Hamwe niterambere ryibihe, abantu barushaho kwita kubidukikije, kandi iterambere ryicyatsi kibisi ryabaye inzira nshya. Kubwibyo, ibinyabuzima bishobora kwangirika ni ngombwa. None ibikoresho bishingiye kuri bio ni ibihe?

Ibikoresho bibogamye bivuga umutungo wa biomass ushobora kuvugururwa wakozwe binyuze muri fotosintezeza nkibikoresho fatizo, bigahinduka mubinyabuzima hakoreshejwe ikoranabuhanga rya fermentation biologiya, hanyuma bigasukurwa kandi bigahinduka polymer mubinyabuzima byangiza ibidukikije. Ibikoresho bishobora kwangirika birashobora kubora muri CO2 na H20 mugihe mikorobe ikora cyangwa ifumbire mvaruganda. Ugereranije n’ibikomoka kuri peteroli, ibikoresho bishingiye kuri bio birashobora kugabanya ibyuka bihumanya ikirere kugera kuri 67%.

Imyuka isanzwe ya karubone mugihe cyose cyakozwe na polymer zimwe (kg CO2 / kg ibicuruzwa):

Mubuzima bwa buri munsi, ntidushobora gukora tudafite ibicuruzwa bya pulasitike, ariko twese tuzi ko plastiki itangiza ibidukikije kandi nigicuruzwa nyamukuru cy "imyanda yera". Nyamara, ibicuruzwa bya pulasitike biragaragara hose mubuzima bwacu bwa buri munsi. Nkigisubizo, plastiki yangirika yagiye ihinduka buhoro buhoro.

Kugira ngo ibyo bishoboke, abahanga bakoze ibicuruzwa bibora -aside polylactique. Iyi plastiki ihindurwamo ibinyamisogwe by’ibimera, ifite ibinyabuzima byiza kandi byangiza ibidukikije kubera gahunda yo kuyitegura ikuraho ibikoresho fatizo bya peteroli bitangiza ibidukikije. Acide Polylactique (PLA) kuri ubu ni kimwe mu bikoresho bikoreshwa cyane, bitanga icyizere, kandi bidahenze cyane.

PLA ni iki?

Poly (acide lactique), mu magambo ahinnye nkaPLA, bizwi kandi nka aside polylactique,CAS 26100-51-6cyangwaCAS 26023-30-3. Acide polylactique ikozwe muri biomass nkibikoresho fatizo, bikomoka kuri kamere kandi ni ibya kamere. Igikorwa cyo guhindura PLA nuburyo bukurikira - abahanga mu bya shimi barashobora guhindura neza ibinyamisogwe byakuwe mubihingwa nkibigori muri LA binyuze muri hydrolysis hamwe na fermentation ya mikorobe, hanyuma bakayihindura muri PLA binyuze muri polymerisiyonike cyangwa gufungura impeta, kugera kuri "magic" yo guhinduka ibihingwa muri plastiki.

Ni ibihe bintu biranga aside polylactique?

Kwangirika rwose

Mugihe cyibikorwa bya mikorobe cyangwa ifumbire mvaruganda, irashobora kwangirika rwose muri CO2 na H2O, kandi igipimo cyibinyabuzima gishobora kugera kuri 90% nyuma yiminsi 180.

Imiterere ya antibacterial naturel

Ifite ubushobozi bwo kubuza Candida albicans, Escherichia coli na Staphylococcus aureus.

Ibinyabuzima

Acide yibikoresho bya lactique ni ibintu bya endogenous mumubiri wumuntu, naho PLA nikintu cyatewe mumuntu cyemejwe na FDA, yakoreshejwe cyane mubuvuzi.

Uburyo bwiza cyane

Ubushyuhe bwo gutunganya PLA ni 170 ~ 230 and, kandi uburyo butandukanye bwo gutunganya nko gukuramo, kurambura, kuzunguruka, kuvuza firime, gutera inshinge, guhumeka, no guhuha birashobora gukoreshwa.

Kudashya

Ntabwo yaka, hamwe na ogisijeni ntarengwa ya 21%, kubyara umwotsi muke, kandi nta mwotsi wirabura.

Ibikoresho fatizo bishobora kuvugururwa

Ibikoresho fatizo bya PLA biva muri biomass ya karubone ikorwa na fotosintezeza.

Hamwe nogukomeza buhoro buhoro imyumvire yabantu ku bidukikije, plastiki y’ibinyabuzima ishobora gusimbuza ibikoresho bya peteroli bitangiza ibidukikije bitangiza ibidukikije. Guhangana no kwiyongera kwa plastiki ibinyabuzima byangiza ibidukikije na societe,PLAbizagerwaho byinjira mubice byinshi byo hepfo ahazaza.
