Aluminiyamu extrusion ndi njira yopangira yomwe imagwiritsidwa ntchito kwambiri yomwe imaphatikizapo kupanga aluminiyamu poyikakamiza kudzera m'mitsempha yopangidwa ndi kufa. Njirayi ndi yotchuka chifukwa cha kusinthasintha kwa aluminiyumu komanso kukhazikika kwake, komanso kutsika kwa carbon footprint poyerekeza ndi zipangizo zina. Komabe, kupanga aluminiyamu kumatulutsabe mpweya wochuluka wa carbon dioxide, umene umakhudza chilengedwe.

Thekupanga aluminiyamuKumaphatikizapo kuchotsa mwala wa bauxite, womwe kenaka umayengedwa kukhala aluminiyamu, ndiyeno amasungunulidwa kukhala aluminiyamu. Njirayi ndi yogwiritsa ntchito mphamvu zambiri ndipo imatulutsa mpweya woipa, zomwe zimapangitsa kuti mafakitale azikhala ndi mpweya wambiri. M'malo mwake, makampani opanga aluminiyamu amatulutsa pafupifupi 1% ya mpweya wa CO2 padziko lonse lapansi.

Pofuna kuthana ndi kukhudzidwa kwa chilengedwe ndi kupanga aluminiyamu, kuyesayesa kukuchitika pofuna kuchepetsa kuchuluka kwa mpweya wamakampani. Njira imodzi ndiyo kuyang'ana kwambiri pakupanga njira zopangira ma aluminiyamu a carbon otsika. Izi zikuphatikizapo kugwiritsa ntchito mphamvu zongowonjezedwanso monga mphamvu ya hydropower kapena mphamvu ya solar kuti ipangitse mphamvu yosungunula, potero kuchepetsa kudalira mafuta oyambira pansi komanso kutsitsa mpweya wa CO2.

Kuphatikiza apo, kupita patsogolo kwaukadaulo kwakulitsa luso la kupanga aluminiyamu, motero kuchepetsa kugwiritsa ntchito mphamvu komanso kutsitsa mpweya wa CO2 pa toni ya aluminiyamu. Kubwezeretsanso aluminiyamu kumathandizanso kuchepetsa kuchuluka kwa kaboni m'makampani, popeza kukonzanso aluminiyamu kumafuna mphamvu zochepa poyerekeza ndi kupanga koyambirira, zomwe zimapangitsa kuti mpweya wa CO2 uchepe kwambiri.

Zakale komanso zomwe zikuyembekezeredwa kuti aluminiyamu yoyambira komanso yosinthidwanso yakula ndipo ikukula kuyambira 1950 mpaka 2050, ndipo gawo la aluminiyamu yosinthidwanso likuchulukirachulukira (Mawu: IAI Material Flow Update)

Kuphatikiza apo, kugwiritsa ntchito aluminiyumu extrusion m'mafakitale osiyanasiyana kumapereka mwayi wokhazikika chifukwa ndi wopepuka, wokhazikika komanso wosinthikanso. Izi zimathandizira ku chuma chozungulira polimbikitsa kugwiritsidwanso ntchito kwa zinthu za aluminiyamu ndikuchepetsa kufunika kopanga koyamba.

Pomaliza, pamene kupanga aluminiyamu kumatulutsa mpweya wa CO2, makampaniwa akhala akugwira ntchito mwakhama kuti achepetse mpweya wake. Kupanga njira zopangira ma aluminiyamu a carbon otsika, kupititsa patsogolo mphamvu zamagetsi komanso kulimbikitsa kukonzanso kwa aluminiyamu zonse zimathandizira pa chitukuko chokhazikika komanso kuyanjana kwa chilengedwe cha mafakitale a aluminiyamu. Popitiriza kuika patsogolo zoyesayesazi, makampaniwa amatha kuchepetsa kukhudzidwa kwa chilengedwe ndikuthandizira tsogolo labwino.

Ngati mukufuna kudziwa zambiri, kapena muli ndi mafunso, khalani omasukaLumikizanani nafe!
