Ese ibikombe by’impapuro bitwikiriwe na PLA birengera ibidukikije kurusha ibikombe by’impapuro bitwikiriwe na PE? Si byo!

Mu buzima bwacu, ibikombe by’impapuro bikoreshwa mu gihe cyo gukoresha amafaranga ni ingenzi cyane. Byaba ari ukwakira abavandimwe, inshuti n’abakiriya, cyangwa nk’uburyo bwo kwamamaza, iki gikombe cy’impapuro kigomba gukoreshwa. Muri iki gihe, ibikombe by’impapuro bikoreshwa mu gihe cyo gukoresha amafaranga ku isoko bikunze gukoreshwa mu gihe cyo gukoresha amafaranga y’impapuro bikozwe muri PE n’ibikombe by’impapuro bikozwe muri PLA. Ni ikihe muri ibi bikoresho bibiri cyiza kandi kitangiza ibidukikije?

Ibikombe gakondo by’impapuro muri rusange bikoresha urwego rwa PE ku buso bw’impapuro zo hasi kugira ngo bibone ubushobozi bwo kwirinda amazi no kwirinda amavuta. Ibikombe by’impapuro byasizweho PE ntibibora, ntibishobora kwangirika, kandi biragoye kongera gukoreshwa. Ibikombe gakondo by’impapuro byasizweho PE biragoye kongera gukoreshwa kuko bigoye gutandukanya firime ya polyethylene iri ku buso bw’impapuro n’igikombe cy’impapuro.

Ibikoresho bya PLA ni ubwoko bushya bw’ibikoresho bishobora kubora. Ni ibikoresho bivanwa mu ifu y’ibigori. Iyo bimaze gukoreshwa, bishobora kubora na mikorobe ziri mu bidukikije mu bihe runaka, kandi kubora bishobora kuvamo dioxyde de carbone na amazi.

Ibikombe bya PLA bikunze kuvugwa nk’uburyo “buzira ibidukikije” aho gukoresha ibikombe bya PE bikozwe mu mpapuro, ikigaragara ni uko PLA ari pulasitiki kandi ifite ibibazo bimwe n’ibikombe bya PE bikozwe mu mpapuro. Uburyo PLA ibora bugomba kuzuza ibintu bibiri: ubushuhe buri hagati ya 50% na 60% n’ubushyuhe buri hagati ya dogere selisiyusi 50-70. Muri ibi bihe, birashoboka ko udukoko dushobora kubora buhoro buhoro PLA nyuma y’amezi menshi cyangwa arengaho. Ariko, biragoye ko ibidukikije karemano bigera ku bushyuhe bukenewe kugira ngo byangirike. Iyo ibicuruzwa bya PLA bitawe uko bishakiye, ntibishobora kwangirika by’ukuri. Kugira ngo PLA yonone, igomba gutunganywa mu nganda mu nganda zihariye zo gufumbira. Mu by’ukuri, ibihugu bike bifite izo nganda.

Byongeye kandi, ubushakashatsi bwagaragaje ko igipimo cya PLA cyo kwangirika kidatandukanye n’icya pulasitiki isanzwe mu mazi meza no mu mazi yo mu nyanja. Ishyirahamwe ry’ibihugu by’i Burayi rishinzwe pulasitiki ryavuze kandi ko pulasitiki zishobora kwangirika zidashobora gufatwa nk’izirinda ibidukikije kurusha pulasitiki gakondo zitabora. Iyo ibyangiritse bitagezweho, nta tandukaniro riri hagati ya “plastiki zishobora kwangirika” na plastiki zisanzwe.

Nubwo ibikombe by’impapuro bitwikiriwe na PLA bishobora kwangirika, igiciro cy’ibikoresho bya PLA kiri hejuru inshuro 2-3 ugereranyije n’icya PE, kandi ibiciro by’ibikoresho fatizo biri hejuru bituma ibiciro byiyongera. Kubwibyo, ibikombe by’impapuro bikoreshwa mu gukoresha rimwe ku isoko ni ibikombe by’impapuro bitwikiriwe na PE.
