Byuzuye Bio-Yangirika Ibikoresho
Mugihe cyo kurema umuco ugezweho, ubwoko bwibicuruzwa bya pulasitike nabyo bizana umwanda wera.Ibikoresho byo kumeza, ibikoresho bya pulasitiki bikoreshwa hamwe na firime ya pulasitiki yubuhinzi biragoye kubitunganya, kandi uburyo bwo kubuvura ni ugutwika no gushyingura.Gutwika bizatanga imyuka myinshi yangiza kandi yanduze ibidukikije.Polimeri mu myanda ntishobora kwangirika na mikorobe mugihe gito kandi ihumanya ibidukikije.Filime isigaye ya plastike ibaho mubutaka, bubuza iterambere ryimizi yibihingwa no kwinjiza amazi nintungamubiri, bigabanya ubutaka bworoshye, kandi bigatuma umusaruro ugabanuka.Amatungo arashobora gupfa azize amara nyuma yo kurya igipfunyika cya plastiki.Urushundura rwo kuroba rwa fibre hamwe nimirongo yatakaye cyangwa yataye mu nyanja byangije byinshi mubuzima bwinyanja, bityo rero ni ngombwa gushyigikira ikoreshwa ryicyatsi no gushimangira kurengera ibidukikije.Ibinyabuzima bishobora kwangirika bihuye nicyerekezo nkibicuruzwa byubuhanga buhanitse nibicuruzwa byo kurengera ibidukikije bigenda bihinduka ubushakashatsi niterambere rishyushye.
Imwe muriyo ni ibikoresho bishobora kwangirika rwose, nka polymer naturelose isanzwe, polycaprolactone yubukorikori, nibindi, kubora kwayo guturuka ahanini: growthikura ryihuse rya mikorobe itera gusenyuka kumubiri kumiterere ya plastike;② Bitewe na mikorobe yibinyabuzima, catalizike ya enzyme cyangwa aside-fatizo ya hydrolysis itandukanye;Gutesha agaciro urunigi rwa radicals yubusa iterwa nizindi mpamvu.
Ikindi cyiciro ni ibikoresho bya biodisintegrating, nk'uruvange rwa krahisi na polyethylene, kubora kwayo guterwa ahanini no gusenya inyongeramusaruro no kugabanuka kw'urunigi rwa polymer, bigatuma uburemere bwa molekile ya polymer bugabanuka ku buryo ishobora guterwa na mikorobe, hanyuma amaherezo kuri dioxyde de carbone (CO2) namazi.
Bio-gusenya ibikoresho bivangwa na polyethylene na polystirene wongeyeho ibinyamisogwe na fotosensitizer.Ubushakashatsi bwerekanye ko imifuka ya pulasitiki ishingiye ku binyabuzima ishingiye ku binyabuzima amaherezo izarangirira mu myanda, bitatewe n’umucyo w’izuba, kabone niyo haba hari iyangirika ry’ibinyabuzima, iyangirika ahanini ni bio-gutesha agaciro.Ikizamini runaka cyerekana ko nta kwangirika kugaragara kwimifuka yimyanda, imifuka yimyanda nta byangiritse bisanzwe.
Kugira ngo ikibazo cy’ibidukikije gikemuke, nubwo plastiki ishingiye kuri krahisi ikora neza kuruta ibicuruzwa bya pulasitiki bikoreshwa, ariko ugakomeza gukoresha polyethylene cyangwa poliester idashobora kwangirika nkibikoresho fatizo, birashobora kuba ibikoresho byangirika gusa, usibye krike yongeyeho irashobora kwangirika, hasigaye umubare munini wa polyethylene cyangwa polyester bizakomeza kandi ntibishobora kwangirika rwose, byangirika mubice, ntibishobora gukoreshwa.Kubwibyo, ibikoresho byuzuye biodegradable bihinduka intumbero yubushakashatsi bwibikoresho byangirika.
