chitoliro cha aluminiyamu

M'zaka zaposachedwapa, ndi chitukuko cha chuma cha padziko lonse komanso kupita patsogolo kwa sayansi ndi ukadaulo, makampani opanga aluminiyamu pang'onopang'ono akukhala gawo lofunika kwambiri pakukula kwachuma cha padziko lonse.

Malinga ndi zomwe mabungwe oyenerera akuneneratu, kukula kwa msika wa aluminiyamu padziko lonse lapansi kudzafika pafupifupi $260 biliyoni mu 2021, ndipo chiwongola dzanja cha pachaka cha kukula kwa aluminiyamu chikuyembekezeka kukhala pafupifupi 4%.

Aluminiyamu monga mtundu wa kulemera kopepuka, kukana dzimbiri, kosavuta kugwira ntchito ndi zina zomwe zili mu chitsulocho, imagwiritsidwa ntchito kwambiri m'magalimoto, zomangamanga, zamagetsi ndi zina. Pakati pawo, makampani a magalimoto ndi omwe amayimiraaluminiyamuMakampani opanga zinthu akukula mofulumira, ndipo mwayi wapadera ndi wakale.

Ndi kupititsa patsogolo chidziwitso cha chilengedwe padziko lonse lapansi, makampani opanga magalimoto akufulumizitsa kusintha kupita ku njira yopepuka, yosunga mphamvu komanso yochepetsa mpweya woipa, komanso kufunikira kwa kugwiritsa ntchitoaluminiyamuPang'onopang'ono zinthu zakhala zikukhudzidwa kwambiri. Pakadali pano, makampani opanga aluminiyamu ndi omwe amapanga magalimoto opepuka oposa 40% padziko lonse lapansi.

Pa nthawi yomweyo, ChinaaluminiyamuMakampani opanga magalimoto akhala amodzi mwa opanga magalimoto akuluakulu padziko lonse lapansi chifukwa msika wawo wamagalimoto wakula mofulumira. Kukwanira ndi kukhwima kwa unyolo wamakampani opanga aluminiyamu kumapereka zinthu zambiri zapamwamba za aluminiyamu pamsika wapadziko lonse lapansi.

Kuphatikiza apo, zinthu zopangidwa ndi aluminiyamu pa zomangamanga, zamagetsi ndi zina, kufunikira kwa msika kukukulirakulira. Zokongoletsa nyumba, zida zapakhomo, zinthu zamagetsi ndi zina, kuchuluka kwa aluminiyamu ndialuminiyamuzinthu. Chifukwa cha khalidwe lake lopepuka, losawonongeka komanso mtengo wotsika, zinthu zopangidwa ndi aluminiyamu zimakopa anthu ambiri.

Ponseponse, chiyembekezo cha chitukuko chaaluminiyamuMsika uli ndi chiyembekezo chachikulu. Pamene chuma cha padziko lonse chikulowa munthawi yatsopano ya chitukuko chofulumira, Chinalco idzachitanso gawo lofunika kwambiri pamsika wapadziko lonse lapansi. Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo komanso kupititsa patsogolo kwa mtundu wa zinthu, makampani opanga aluminiyamu adzabweretsa mwayi wabwino wopititsa patsogolo.
