I nā makahiki i hala iho nei, me ka hoʻomohala ʻana o ka hoʻokele honua a me ka holomua o ka ʻepekema a me ka ʻenehana, ua lilo ka ʻoihana alumini i mea nui o ka hoʻokele waiwai honua.

Wahi a ka wānana o nā hui kūpono, e piʻi ka nui o ka mākeke alumini honua ma kahi o $ 260 biliona ma 2021, ʻo ka nui o ka ulu ʻana o ka makahiki he 4%.

ʻO ka alumini e like me keʻano o ke kaumaha māmā, ka paleʻana i ka corrosion, maʻalahi ka hana a me nāʻano'ē aʻe o ka metala, hoʻohana nuiʻia i nā kaʻa kaʻa, ke kūkuluʻana, nā mea uila a me nāʻoihana'ē aʻe.Ma waena o lākou, ʻo ka ʻoihana kaʻa ma ke ʻano he ʻelele oaluminikaKe ʻike nei ka ʻoihana huahana i ka hoʻomohala wikiwiki ʻana, i lawe ʻia i kahi manawa kūpono.

Me ka hoʻomau mau ʻana o ka ʻike kaiapuni honua, ke wikiwiki nei ka ʻoihana hana kaʻa i ka hoʻololi ʻana i ke kuhikuhi o ka māmā, mālama i ka ikehu a me ka carbonization haʻahaʻa, a me ka noi noi oaluminikaUa hopohopo nui ʻia nā huahana.I kēia manawa, ʻoi aku ka ʻoihana alumini ma mua o 40% o nā kaʻa māmā o ka honua.

I ka manawa like, ʻo Kinaaluminikaua lilo ka ʻoihana i kekahi o nā mea hana nui loa o ka honua no ka mea ua hoʻonui wikiwiki ʻia kāna mākeke kaʻa kūloko.ʻO ka maikaʻi a me ke oʻo ʻana o ke kaulahao ʻoihana alumini e hāʻawi i ka nui o nā huahana alumini kiʻekiʻe no ka mākeke honua.

Eia kekahi, nā huahana alumini i ke kūkulu ʻana, nā mea uila a me nā māla ʻē aʻe, ke ulu nei ka makemake o ka mākeke.ʻO ka hoʻonani hale, nā mea hana hale, nā huahana uila a me nā mea ʻē aʻe, ka nui o ka alumini aaluminikahuahana.Ma muli o kona ʻano māmā, ʻaʻahu kūʻokoʻa a me ke kumukūʻai haʻahaʻa, nā huahana alumini e huki i ka nui o nā mea kūʻai.

ʻO ka holoʻokoʻa, nā manaʻo hoʻomohala oaluminikamakeke ua hoohiki loa.Ke komo nei ka hoʻokele waiwai o ka honua i kahi manawa hou o ka hoʻomohala wikiwiki ʻana, e pāʻani ana ʻo Chinalco i kahi kuleana nui i ka mākeke honua.Me ka holomua mau o ka ʻepekema a me ka ʻenehana a me ka hoʻomaikaʻi mau ʻana i ka maikaʻi o ka huahana, ua paʻa ka ʻoihana alumini e hoʻolauna i nā manawa hoʻomohala ʻoi aku ka maikaʻi.
