Indabyo zishobora kwangirika zishobora guhindura urwego rw'ubwiza.

Ubuzima bwuzuyemo amapaki meza, amacupa yo kwisiga, amabakure y'imbuto n'ibindi byinshi, ariko byinshi muri byo bikozwe mu bikoresho by'uburozi kandi bidakomeye bigira uruhare mu kwanduzanya kwa pulasitiki.

Vuba aha, abashakashatsi bo muri Kaminuza ya Cambridge mu Bwongereza babonye uburyo bwo gukora ubwiza burambye, budahumanya kandi bushobora kubora buva muri selulose, inkingi ikomeye y’inkuta z’uturemangingo tw’ibimera, imbuto n’imboga. Inyandiko zijyanye na byo zasohotse mu kinyamakuru Nature Materials on the 11th.

Iyi filime ikoze muri nanocrystals za cellulose, ikoresha amabara y’imiterere yayo kugira ngo ihindure urumuri kugira ngo itange amabara meza. Urugero, muri kamere, amababa y’ibinyugunyugu n’ubwoya bw’ingwe ni ibihangano by’ubukorikori bifite amabara y’imiterere, bitazashira nyuma y’ikinyejana.

Abashakashatsi bavuga ko bakoresheje uburyo bwo kwihuza, cellulose ishobora gukora filime z'amabara meza. Mu kunoza uburyo cellulose ikoreshwa mu gusiga no gusiga, itsinda ry'abashakashatsi ryashoboye kugenzura byimazeyo uburyo bwo kwihuza, bituma ibikoresho bikorerwa mu buryo bwinshi mu mibumbe. Uburyo bwabo bujyanye n'imashini zisanzwe zikoreshwa mu nganda. Hakoreshejwe ibikoresho bya cellulose biboneka ku isoko, bifata intambwe nke gusa kugira ngo bihinduke icyuma kirimo iyi glitter.

Nyuma yo gukora filime za cellulose ku rugero runini, abashakashatsi bazisya mu duce duto twazo dukoreshwa mu gukora irangi cyangwa ibara ry’umutuku. Utwo duce turabora, nta plastiki irimo, kandi ntabwo tugira uburozi. Byongeye kandi, inzira ikoresha ingufu nke cyane ugereranyije n’uburyo busanzwe.

Ibikoresho byabo bishobora gukoreshwa mu gusimbuza uduce twa pulasitiki tw’umutuku n’uduce duto tw’imyunyu ngugu dukoreshwa cyane mu kwisiga. Amabara gakondo, nk’ifu y’umutuku ikoreshwa mu buzima bwa buri munsi, ni ibikoresho bidahoraho kandi byangiza ubutaka n’inyanja. Muri rusange, imyunyu ngugu igomba gushyushywa ku bushyuhe bwinshi bwa 800°C kugira ngo ikore uduce twa piramidi, kandi ntabwo bifasha ibidukikije.

Filimi ya cellulose nanocrystal yateguwe n'itsinda ishobora gukorwa ku rwego runini hakoreshejwe uburyo bwa "roll-to-roll", nk'uko impapuro zikorwa mu giti, bigatuma iki gikoresho kiba icyambere mu nganda.

Mu Burayi, inganda z’ubwiza zikoresha toni zigera ku 5.500 za microplastic buri mwaka. Umwanditsi mukuru w’iyi nyandiko, Porofeseri Silvia Vignolini, wo mu ishami rya chimie rya Yusuf Hamid muri Kaminuza ya Cambridge, yavuze ko bizera ko iki gicuruzwa gishobora guhindura urwego rw’ubwiza.
