Gukuramo aluminiyumu ni uburyo bukoreshwa cyane mu gukora burimo gukora aluminiyumu mu kuyihatira gufungura mu rupfu. Inzira irazwi cyane kubera aluminiyumu ihindagurika kandi irambye, kimwe na karuboni nkeya ugereranije nibindi bikoresho. Nyamara, umusaruro wa aluminiyumu uracyatanga umusaruro mwinshi w’ibyuka bihumanya ikirere, bigira ingaruka ku bidukikije.

Uwitekaumusaruro wa aluminiumbirimo gukuramo amabuye ya bauxite, hanyuma agatunganyirizwa muri alumina, hanyuma agashonga muri aluminium. Inzira ikoresha ingufu nyinshi kandi ikarekura karuboni ya dioxyde, ikongera inganda za karubone. Mubyukuri, inganda za aluminiyumu zisohora hafi 1% byangiza imyuka ya CO2 ku isi.

Mu rwego rwo gukemura ingaruka z’ibidukikije ku musaruro wa aluminiyumu, hashyizweho ingufu mu kugabanya inganda za karuboni. Uburyo bumwe nukwibanda mugutezimbere uburyo bwa karubone nkeya ya aluminium. Ibi bikubiyemo gukoresha ingufu zishobora kuvugururwa nka hydropower cyangwa ingufu z'izuba kugirango ingufu zogushonga, bityo bigabanye gushingira ku bicanwa biva mu kirere no kugabanya imyuka ihumanya ikirere.

Byongeye kandi, iterambere mu ikoranabuhanga ryongereye umusaruro wa aluminiyumu, bityo kugabanya ingufu no kugabanya imyuka ihumanya ikirere kuri toni ya aluminium. Kongera gukoresha aluminiyumu kandi bigira uruhare runini mu kugabanya ikirere cya karuboni, kubera ko gutunganya aluminiyumu bisaba ingufu nke ugereranije n’umusaruro w’ibanze, bigatuma igabanuka ry’ibyuka bihumanya ikirere.

Umusaruro wamateka kandi uteganijwe kubyazwa umusaruro wa aluminiyumu wongeye kwiyongera kandi uragenda wiyongera kuva 1950 kugeza 2050, kandi igipimo cya aluminiyumu itunganijwe cyiyongera (Inguzanyo: IAI Material Flow Update)

Byongeye kandi, gukoresha aluminiyumu mu nganda zinyuranye bitanga inyungu zirambye kuko zoroshye, ziramba kandi zishobora gukoreshwa neza. Ibi bigira uruhare mubukungu bwizunguruka mugutezimbere ikoreshwa ryibicuruzwa bya aluminiyumu no kugabanya ibikenerwa byibanze.

Mu gusoza, mugihe umusaruro wa aluminiyumu utanga imyuka ihumanya ikirere, inganda zakoze cyane kugirango zigabanye ikirere cyayo. Gutezimbere uburyo bwa karuboni nkeya ya aluminiyumu, kunoza imikorere yingufu no guteza imbere gutunganya aluminiyumu byose bigira uruhare mu iterambere rirambye no kubungabunga ibidukikije byinganda za aluminium. Mugukomeza gushyira imbere izo mbaraga, inganda zirashobora kurushaho kugabanya ingaruka z’ibidukikije no kugira uruhare mu bihe biri imbere.

Niba ushaka kumenya byinshi, cyangwa ufite ikibazo, wumve nezatwandikire!
