Umufuka wo gupakira wangiritse, ibisobanuro birasuzuguritse, ariko ibipfunyika byangirika bigabanijwemo "kwangirika" na "kwangirika rwose" ubwoko bubiri.
Umufuka wa pulasitiki ushobora kwangirika bikozwe mu byatsi by’ibimera n’ibindi byangiza umubiri w’umuntu n’ibidukikije, bitandukanye na plastiki eshatu zikorana buhanga, nyuma y’imyanda, bitewe n’ibidukikije by’ibinyabuzima, irashobora kubora ubwayo, bititaye ku bantu cyangwa ku bidukikije. ntacyo bitwaye, ni icyatsi kibisi.Umufuka wa pulasitiki wangiritse ni ubwoko bwimifuka yo kugura ishobora guteshwa agaciro kandi byoroshye.
Imifuka ya pulasitike yangirika irashobora kugabanywamo ubwoko bubiri uhereye kubitandukanya ibikoresho fatizo nibintu byangirika:
• Umufuka wa pulasitike ukorwa cyane cyane muri plastiki ya polyethylene, ivanze na krahisi hamwe n’ibindi bintu byangiza ibinyabuzima, bizwi kandi ko ari umufuka wa pulasitiki wangiza.Ubu bwoko bwimifuka ya pulasitike ibora cyane cyane kubikorwa bya mikorobe.
• Ubundi bwoko bugizwe ahanini na plastike ya polyethylene, ivanze nifu ya minerval nka agent desorption agent na calcium karubone, nayo bita umufuka wa plastike yoroheje.Ubu bwoko bwimifuka ya pulasitike buravunika munsi yizuba.
Umufuka wangiritse rwose bivuze ko imifuka ya pulasitike yose yangiritse mumazi na karuboni ya dioxyde.Inkomoko nyamukuru yibi bikoresho byangirika bitunganyirizwa mu bigori, imyumbati nibindi bikoresho muri acide lactique, izwi kandi nka PLA.Acide Poly Lactic Acide (PLA) nubwoko bushya bwibinyabuzima byangiza kandi byongera ibinyabuzima bishobora kwangirika.Ibikoresho fatizo bya krahisi byeguriwe kubona glucose, hanyuma glucose hamwe nubwoko bumwebumwe bisembuwe kugirango bibyare aside irike ya lactique, hanyuma PLA ifite uburemere buke bwa molekile ikomatanyirizwa hamwe nuburyo bwo guhuza imiti.Ifite ibinyabuzima byiza.Nyuma yo kuyikoresha, irashobora kwangirika rwose na mikorobe miterere yabantu mubihe byihariye, hanyuma ikabyara karuboni n'amazi.Ntabwo yangiza ibidukikije, bifite akamaro kanini mu kurengera ibidukikije kandi ni ibikoresho byangiza ibidukikije ku bakozi.
