Ma hea e hele ai nā kumukūʻai polyolefin ke emi ka loaʻa kālā o ka ʻoihana huahana plastik?

I Kepakemapa 2023, ua hoʻemi ʻia nā kumukūʻai hale hana o nā mea hana ʻenehana ma ka ʻāina e 2.5% i kēlā me kēia makahiki a hoʻonui ʻia e 0.4% mahina ma ka mahina; Ua ho'ēmi nā kumukūʻai kūʻai o nā mea hana ʻoihana e 3.6% makahiki a hoʻonui ʻia e 0.6% mahina ma ka mahina. Mai Ianuali a Sepatemaba, ma ka awelika, ua emi ke kumukūʻai o ka hale hana o nā mea hana ʻoihana e 3.1% i hoʻohālikelike ʻia i ka manawa like o ka makahiki i hala, ʻoiai ke kumukūʻai kūʻai o nā mea hana ʻoihana i emi iho e 3,6%. Ma waena o nā kumukūʻai ex factory o nā mea hana ʻenehana, ua emi ke kumukūʻai o ke ʻano hana e 3.0%, e pili ana i ka pae holoʻokoʻa o nā kumukūʻai ex factory o nā mea hana ʻenehana ma kahi o 2.45 pakeneka. Ma waena o lākou, ua emi nā kumukūʻai o ka ʻoihana mining e 7.4%, aʻo nā kumukūʻai o ka ʻoihana maka a me ka ʻoihana hana i emi iho e 2.8%. Ma waena o nā kumukūʻai kūʻai o nā mea hana ʻenehana, ua emi nā kumukūʻai o nā mea kemika i ka 7.3%, nā kumukūʻai o ka wahie a me nā huahana mana i hoʻemi ʻia e 7.0%, a ua hoʻemi ʻia ka ʻoihana kaila a me ka plastic i ka 3.4%.
Ua emi iho ke kumukūʻai o ka ʻoihana hana a me ka ʻoihana maka i kēlā me kēia makahiki, a ua emi ka ʻokoʻa ma waena o nā mea ʻelua, me ka emi ʻana o nā mea ʻelua i ka mahina i hala. Mai ka hiʻohiʻona o nā ʻoihana i hoʻokaʻawale ʻia, ua emi pū nā kumukūʻai o nā huahana plastik a me nā mea synthetic, a ua hōʻemi pū ka ʻokoʻa ma waena o nā mea ʻelua i ka mahina i hala. E like me ka nānā ʻana i nā wā ma mua, ua hōʻea ka waiwai o lalo i kahi kiʻekiʻe o ka manawa a laila hoʻomaka ka emi ʻana, e hōʻike ana ua hoʻomaka ka piʻi ʻana o nā kumukūʻai maka a me nā huahana, a ʻoi aku ka lohi o ka hoʻihoʻi ʻana i nā kumukūʻai o nā huahana. ʻO ke kumukūʻai o nā mea waiwai polyolefin e like me kēia. ʻO ka haʻahaʻa haʻahaʻa i ka hapa mua o ka makahiki ʻo ia paha ka lalo o ka makahiki, a ma hope o ka manawa o ka hoʻonui, hoʻomaka ka fluctuate i kēlā me kēia manawa.
