Mu gihe za leta n'inganda ku isi yose zihutisha ingamba zo kugera ku ntego z'iterambere rirambye, alumina irimo gukoreshwa irimo kumenyekana nk'ikintu cy'ingenzi cyane mu kurengera ibidukikije no guteza imbere inganda. Ubwoko bwa okiside ya aluminiyumu ifite imyenge myinshi kandi igaragara ku buso burebure burimo gukenerwa cyane mu nzego nyinshi, kuva ku nganda zitunganya amazi zo mu mujyi kugeza ku nganda zitunganya peteroli.
Gusukura amazi bikomeje kuba ingenzi mu iterambere
Igice cyo gutunganya amazi gikomeje kwibanda ku ikoreshwa rya alumina ikoreshwa mu mazi, kikaba ari cyo gifite umugabane munini ku isoko mu 2026. Kubera ko abantu bagera kuri miliyari 2 ku isi badafite amazi meza yo kunywa, nk'uko raporo ziherutse gutangazwa na 联合国 zibigaragaza, gukenera imashini ziyungurura amazi neza ntibyigeze biba ibyihutirwa cyane kurusha uko byari bimeze mbere.
Ubushobozi budasanzwe bwa alumina ikora mu gukurura imyanda nka fluoride, arsenic, na selenium butuma igira akamaro kanini mu turere duhura n’ubwandu bw’amazi yo mu butaka. Mu ntara za Rajasthan na Gujarat mu Buhinde, aho fluorosis ikomeje kuba ikibazo cy’ubuzima rusange, sisitemu nini zo gutunganya amazi zishingiye kuri alumina ikora mu baturage zaraguwe muri uyu mwaka. Mu buryo nk’ubwo, imishinga yo mu karere ka Rift Valley muri Afurika y’Iburasirazuba irimo gukoresha ibyo bikoresho mu gukemura ikibazo cya fluoride iboneka mu mazi yo kunywa.
Uturere two mu bihugu byateye imbere na two turimo gukoresha alumina ikora mu gutunganya amazi yanduye no gukuraho imyanda ihumanya. Amabwiriza mashya yo muri California yo gukoresha amazi mu buryo bushya, yashyizwe mu bikorwa mu ntangiriro za 2026, yatumye habaho ishoramari mu ikoranabuhanga rigezweho ryo kuyungurura amazi rikoresha alumina ikora.
Gukoresha "Catalyst" biriyongera mu rwego rwa peteroli
Uretse gutunganya amazi, uruhare rw'ibikoresho nk'umusemburo n'inkunga mu nganda za peteroli rukomeje kwiyongera. Ubushyuhe bwa alumina bushobora guhagarara neza hamwe n'ubushyuhe bugenzurwa bituma biba byiza cyane mu bikorwa birimo na catalysts za Claus zo kugarura sulfur, gukora polyethylene, no gukora hydrogenation mu buryo bw'umwihariko.
Kubera ko ingufu zikenewe ku isi zikomeje kwiyongera, inganda zitunganya ifumbire zirimo kunoza imikorere yazo kugira ngo zirusheho gukora neza kandi zihuze n’amahame agenga ibidukikije. Katalysts zishingiye kuri alumina zikoreshwa mu gukuraho neza ibintu bya sulfur mu bikomoka kuri peteroli, bigafasha abatunganya ifumbire kubahiriza amabwiriza agenga lisansi nkeya muri Amerika ya Ruguru, i Burayi na Aziya.
Aziya na Pasifika ni byo byazamuye ikoreshwa ry'ibicuruzwa
Mu rwego rw'ubutaka, akarere ka Aziya na Pasifika gakomeje kuba akarande ka mbere mu gutanga no gukoresha alumina nyinshi. Gukomeza kwagura inganda no gutunganya ibidukikije mu Bushinwa bituma habaho ubusabe bunini, mu gihe urwego rw'inganda rukura vuba mu Buhinde ndetse n'iterambere ry'ibikorwa remezo by'imijyi bitanga amahirwe mashya.
Ibihugu byo muri Aziya y'Amajyepfo y'Uburasirazuba, cyane cyane Vietnam na Indoneziya, birimo kuzamuka nk'amasoko mu iterambere mu gihe birimo gutera imbere mu nganda no gushyiraho amategeko akaze yo kubungabunga ibidukikije. Amasezerano aherutse gutangwa n'Ishyirahamwe ry'Ibihugu byo muri Aziya y'Amajyepfo y'Uburasirazuba ku birebana n'amahame y'ubuziranenge bw'amazi yatumye ibihugu bigize uyu muryango bivugurura ibikorwa remezo byo gutunganya amazi, bigafasha abatanga alumina babikora.
Ikoreshwa mu buvuzi no mu miti rirarushaho gukundwa
Icyerekezo kiri kugaragara muri 2026 ni ukwiyongera k’ikoreshwa rya alumina ikora ibikoresho by’ubuvuzi n’imiti. Ibi bikoresho bikora nk’uburyo bwiza bwo kongerera ubushobozi imiti mu gutunganya no gupima imiti. Ibigo bikora imiti n’inkingo byongereye imbaraga zabyo kuri alumina ikora ibikoresho mu gukuraho imyanda no kwemeza ko ibicuruzwa bifite umutekano.
Gukoresha amenyo nabyo bigaragaza isoko ryihariye ariko rigenda rikura. Alumina ikoreshwa muri sima zimwe na zimwe z'amenyo kandi ikoreshwa mu gusukura amenyo mu buryo bw'umwuga, bigatuma irushaho gukomera no kudakora neza.
Iterambere ry'uruhererekane rw'ibicuruzwa n'imigendekere y'ibikoresho fatizo
Uruhererekane rw'ibicuruzwa bya alumina rwagaragaje ko rushobora guhangana n'ibibazo bikomeye bya politiki bikomeje kugira ingaruka ku bucuruzi mpuzamahanga. Bauxite, ibikoresho by'ibanze bikoreshwa mu gukora alumina, iracyaboneka cyane, nubwo ibiciro by'ubwikorezi n'ibiciro by'ingufu bikomeje kugira ingaruka ku biciro bya nyuma by'ibicuruzwa.
Ibihugu bikomeye bitunganya, birimo Ositaraliya, Ubushinwa na Brezili, byakomeje gutanga umusaruro uhamye, mu gihe gahunda zo kongera gukoresha ibikoresho byo kongera gukoresha zigenda zitera imbere. Ibigo byinshi by’i Burayi byashyize imbere inzira zo kuvugurura alumina yakoreshejwe mu nganda, kugabanya imyanda no gutanga ubundi buryo buhendutse bwo gukoresha ibikoresho bidafite isuku.
Udushya mu bya tekiniki twongera imikorere
Inzego z’ubushakashatsi n’abakora ibikoresho bakomeje kunoza ibicuruzwa bya alumina bikoreshwa mu buryo bwihariye. Udushya duherutse gukorwa turimo ingano y’uduce tw’ibice byakozwe mu buryo bwa tekiniki butuma imiterere y’amazi anyura mu buryo buhamye, hamwe n’uburyo bwo guhindura ubuso hamwe n’uburyo bwo guhitamo ibintu byanduye byibandwaho.
Ibikoresho bya alumina bikozwe mu buryo bwa nanostructured, nubwo bikiri mu cyiciro cy’ubushakashatsi, bigaragaza icyizere ku bikorwa byihariye bisaba ubuso burebure cyane kandi byihuse mu kuyungurura amazi. Imishinga y’igerageza mu gutunganya amazi yanduye mu nganda irimo gusuzuma ubushobozi bw’ibi bikoresho bigezweho mu bucuruzi.
Gutegereza imbere
Abakurikirana inganda biteze ko alumina ikora izakomeza gutera imbere mu gihe iterambere ry’ibikorwa remezo, amategeko agenga ibidukikije, no kwaguka kw’inganda bihurira. Uburyo ibikoresho bikoreshwa mu buryo butandukanye, igiciro gito, n’imikorere yabyo bigaragara ko ari byiza mu gukomeza gukoreshwa mu bikorwa bisanzwe n’ibishya.
Kubera ko imihindagurikire y'ikirere ikomeje kwiyongera k'umuvuduko ku mutungo w'amazi no guteza imbere inganda bitera imbogamizi nshya mu kuvura, alumina ikora izagira uruhare runini mu kurinda ubuzima rusange no gutuma inganda zitera imbere ku isi hose.
