Abacondoozi kuruga omu yunivasite ya Chung-Ang omuri South Korea nibeega aha miringo y’okukwaata n’okukoresa omuyaga gwa kaboni barikukoresa ebisasiro nari eby’obugaiga by’omu itaka nk’eby’okurya. Eki nikihamya ngu tekinologiya neebaasa kutunga eby’entaasya.
Omu kucondooza oku okusya, ekibiina ekirikwebemberwa Purofeesa Sungho Yoon hamwe na Purofeesa omuhwezi we Chul-Jin Lee bakacondooza aha kukoresa omuyaga gw’omu itaka ogwa dolomite omu makorero kukora ebintu bibiri ebirikubaasa kuguzibwa: calcium formate na magnesium oxide.
Okucondooza oku, “Okuhindura kw’amaani kw’ebintu bya Dolomite Magnesium na Calcium Ions kuba ebintu by’omugasho ebirikwongera omuhendo orikukoresa omuyaga gwa Carbon Dioxide,” kukashohozibwa omu katabo akarikucondooza aha by’emibazi.
Empindahinduka y‘obwire n‘enshonga y‘amaani erikwetenga kuheebwa omutima gw‘okubanza. Ekirugiremu, amahanga omu nsi yoona nigakora enkora z’okukyendeeza aha kabi akarikureeta.
Nk’eky’okureeberaho, ekibiina ky’omukago gwa Buraaya nikiha enteekateeka y’ebiragiro bingi eby’okuhikiiriza obutagira rubaju omu mbeera y’obwire omu mwaka 2050. Ekibiina kya European Green Deal nakyo nikihamya obukuru bw’okukyendeeza aha nshaho z’omuyaga.
Ekirugiremu, abanyasayansi bariyo nibacondooza aha tekinologiya y’okukwata n’okukozesa omuyaga gwa kaboni nk’omuringo ogurikuraganisa ogw’okujanjaaza okubiika n’okukora omuyaga gwa kaboni aha sente nkye.
Kwonka okucondooza okukozirwe omu nsi yoona aha kukwaata n’okukozesa kaboni nikugarukira aha birungo by’okuhindura ebirikuhika 20.
Ahakuba enshonga z‘okushohoza CO2 zitari zimwe na zimwe, okugira ebirungo bingi ni kikuru munonga.
Eki nikyoreka obukuru bw’okwega omu bwijwire aha miringo y’okuhindura omuyaga ogurikwetwa carbon dioxide ogurimu ebiriisa bikye.
Omu kucondooza oku okusya, ekibiina eki kikozeise ekirungo (Ru/bpyTN-30-CTF) kwongyera aha muyaga gwa kaboni. Ekirugiremu n’ebintu bibiri ebyabaire biri eby’omuhendo: ebiriisa bya calcium formate na magnesium oxide.
Calcium formate neekoresibwa nk’ekintu ekirikugaita sementi, ekirungo ky’okukyendeeza omuyaga, n’ekirungo ky’okugaita eby’okurya by’enyamaishwa, hamwe n’ebindi nk’okushemeza oruhu.
Enkora ya tiimu egi terikubaasika kwonka, kureka n’okurahuka munonga, neereetaho ekintu omu dakiika itaano zonka aha butagasi bw’omu kishengye.
Omuri ebyo, abacondoozi nibateekateeka ngu omuringo ogu nigubaasa kukyendeeza aha butagatsi bw’ensi n’ebicweka 20% waagyeragyeranisa n’emiringo y’obuhangwa ey’okukora calcium formate.
“Hariho okweyongyera kw’okwenda kukoresa omuyaga gwa carbon dioxide kuhanga ebintu by’omuhendo ebirikubaasa kuhwera kukyendeeza aha kabi akarikuruga omu mpindahinduka y’obwire obwo barikureetaho eby’entaasya.
Purofeesa Yoon akagira ati: “Omu kugaita ebiriisa bya carbon dioxide n’ebiriisa ebirikuhindura ebiriisa bya cation, hakabaho omuringo gw’okushemeza eby’ekyoma omu bwire bumwe kandi bikareetaho formate ey’omuhendo.”
Abacondoozi bakashwijuma yaaba omuringo gwabo nigubaasa kuza omu mwanya gw’emiringo y’okukora ebintu eriho hati. Okubaasa kukora eki, bakacondooza aha nkora y‘okuhindura CO2 erikugumizamu n‘eby‘obuhangwa n‘eby‘entasya.
Purofeesa Yin akashoboorora ati: “Kurugiirira aha byarugamu, nitubaasa kugira ngu omuringo gwaitu n’omuringo ogundi ogutarikushiisha eby’obuhangwa ogurikubaasa kuza omu mwanya gw’emiringo y’obuhangwa kandi gukahwera kukyendeeza aha nshaho ezirikuruga omu makorero.”
N‘obu amatsiko g‘okuhindura omuyaga gwa kaboni kuba ebintu omu muringo ogutarimu kugaruka enyima garikuraganisa, emiringo egi terikuba eyorobi kugyezesa.
Tekinologiya za CCU ezirikukira obwingi tizikatandikire kukora eby‘obushuubuzi ahabw‘okuba obushoboorozi bwazo omu by‘entasya buri ahansi waagyeragyeranisa n‘emiringo y‘obushuubuzi ey‘obuhangwa.
"Twine kugaita enkora ya CCU n'okugaruzaho kasasiro kubaasa kugihindura ey'omugasho omu by'obuhangwa n'eby'entaasya. Eki nikibaasa kuhwera okuhikiiriza ebigyendererwa by'okukyendeeza aha nshaho omu biro by'omumaisho," Dr Lee nikwo yaahendera.
Innovation News Network neekureetera amakuru g'okucondooza n'okukora ebintu bisya omu bya sayansi, eby'obuhangwa, amaani, ebintu ebikuru ebikuru, tekinologiya n'emotoka z'amashanyarazi.
Okwetonganira: Webusayiti egi n’ey’okwetongora kandi teine ​​bujunaanizibwa aha biri aha mikura y’aheeru. Yetegyereze ngu esimu nizibaasa kuhandiikwa ahabw‘okutendeka n‘okureeberera. © Emikutu ya Buraaya yoona Ltd.
