Iterambere ry'ubuhinga bushasha bw'icatsi kibisi

Bishingiye ku ntego z'"dual carbon", hariho iterambere rikomeye ryashitsweko mu guhingura ibikoresho vy'ivyatsi mu gisata c'amabisi. Ishirahamwe ry’ubuhinga bushasha ryarashoboye gutegura neza ibikoresho vyo gukingira umuriro bishingiye ku binyabuzima (bio-) vy’imiyoboro y’amazi y’umuriro muto inyuma y’imyaka ibiri y’ubushakashatsi n’iterambere, rikoresheje aside polylactic (PLA) yahinduwe n’ibindi bikoresho bishingiye ku binyabuzima. Ivyo bitanga inzira nziza ku nganda zo kugabanya ivyuka bihumanya ikirere ku nzira y’ibikoresho.

Ivyo bikoresho bikomoka ku bihingwa bishobora gusubirwamwo nk’ibigori n’imyungu, bishobora gutuma ubushuhe bushobora guhangana n’ubushuhe burenze degre 130 kandi bikaba bitera imbere cane mu bijanye no gukingira umuriro biciye mu buryo buteye imbere bwo guhindura ibintu. Ivyagezwe n’ibigo vy’igerageza vy’abandi, ibimenyetso nyamukuru birimwo inkomezi z’ivyuma n’imiterere y’ivyuma bihuye n’ibisabwa vy’inganda, bikaba bishoboza gusubirira bimwe bishitse ibikoresho vy’ivyuma vya kera.

Ikizwi n’uko ivyo bikoresho biva mu mwuka w’ikirere mu gihe c’uguhingura biri hasi cane y’ivyo bikoresho vya kera. Igenzura ry’ingendo y’ubuzima (LCA) ryerekana ko gukoresha toni 1 y’ivyo bikoresho bishingiye ku binyabuzima-bishobora kugabanya ivyuka bihumanya ikirere n’amatoni nka 2,5. Vyongeye, ivyo bintu birashobora kwonona biciye ku gutera ivyatsi mu nganda iyo bimaze gukoreshwa, ivyo bikaba bituma bidakomeza guhumanya ibidukikije.

Ivyo bikoresho bishasha vyaronse ivyemezo vyinshi kandi vyatanguye igerageza ry'ibice bitobito-mu migambi y'agaciro kanini. Umuyobozi w’umugambi yari muri ivyo bigeragezo yavuze ko bitafashije gusa uwo mugambi kuronka amanota y’inyongera ku bijanye n’icemezo c’inyubako zidakoreshwa ivyatsi bitotahaye, ariko kandi ko vyasubije ivyo abashoramari n’abakoresha biteze ku bijanye n’ubuzima buramba. Kubera amategeko agenga ibidukikije agenda arushiriza gukomera be n’ivyo isoko risaba bigenda birahinduka, iki gikoresho co gukingira ibidukikije gishingiye ku binyabuzima-citezwe ko kizoba inzira nyamukuru y’ubuhinga ku bijanye n’ubuhinga bwo gukora amabisi kugira ngo haboneke ihinduka ry’ivyatsi bitotahaye.
