Umufuka wapakira wangiritse bisobanura kwangirika, ariko igikapu cyo gupakira cyangiritse kigabanijwe muburyo bubiri: kwangirika no kwangirika rwose.Ibifuka bipfunyika bipfunyika bivuga kongeramo umubare munini winyongera (nka krahisi, ibinyamisogwe byahinduwe cyangwa izindi selile, fotosensiseri, ibinyabuzima, nibindi) bigenda byangirika.Imifuka yo gupakira yangiritse rwose yerekana imifuka ipakira plastike yangiritse rwose mumazi na karuboni ya dioxyde.Inkomoko nyamukuru yibi bikoresho byangirika rwose ni ugutunganya ibigori n imyumbati muri aside ya lactique, cyangwa PLA.
Acide Polylactique (PLA) ni matrike ya biologiya nibintu bishya bishobora kwangirika.Gukoresha ibinyamisogwe nkibikoresho fatizo, kwezwa kugirango ubone glucose, hanyuma uhindure glucose hamwe nubwoko bumwe na bumwe kugirango ubone aside irike yuzuye ya lactique, hanyuma ushiremo aside polylactique hamwe nuburemere bwa molekile runaka ukoresheje synthesis.Ifite ibinyabuzima byiza.Nyuma yo kuyikoresha, irashobora kwangizwa rwose na mikorobe miterere yabantu mubihe byihariye kugirango habeho dioxyde de carbone namazi, bidahumanya ibidukikije.Nibyiza cyane kurengera ibidukikije kandi nibikoresho byangiza ibidukikije kubakozi.
Kugeza ubu, ibikoresho nyamukuru bishingiye kuri bio yumufuka wuzuye wapakiye ugizwe na PLA + PBAT, ishobora kubora burundu mumazi na dioxyde de carbone mumezi 3-6 mugihe ifumbire mvaruganda (dogere 60-70), itanduye umwanda ibidukikije.Kuki wongeyeho PBAT, uruganda rukora umwuga wo gupakira ibintu byoroshye, ibisobanuro bikurikira ni uko PBAT adipic acide, 1,4-butanediol, acide terephthalic acide copolymer, cyane cyane ni biodegradable synthèque alifatique na aromatic polymer Tayiwani, PBAT ifite ibintu byoroshye guhinduka, irashobora gukora gukuramo firime, kuvuza gutunganya, gutwikira nibindi gutunganya.Intego yo guhuza PLA na PBAT ni ukunoza ubukana, ibinyabuzima ndetse no guhinduka kwa PLA.PLA na PBAT ntibishobora kubangikanya, guhitamo rero guhuza neza birashobora kunoza imikorere ya PLA.
