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

I Kepakemapa 2023, ua emi nā kumukūʻai hale hana o nā mea hana ʻoihana ma ka ʻāina holoʻokoʻa ma 2.5% makahiki-ma-makahiki a piʻi aʻe ma 0.4% mahina ma ka mahina; Ua emi nā kumukūʻai kūʻai o nā mea hana ʻoihana ma 3.6% makahiki-ma-makahiki a piʻi aʻe ma 0.6% mahina ma ka mahina. Mai Ianuali a Kepakemapa, ma ka awelika, ua emi ke kumukūʻai hale hana o nā mea hana ʻoihana ma 3.1% i hoʻohālikelike ʻia me ka manawa like i ka makahiki i hala, ʻoiai ua emi ke kumukūʻai kūʻai o nā mea hana ʻoihana ma 3.6%. Ma waena o nā kumukūʻai ex-hale hana o nā mea hana ʻoihana, ua emi ke kumukūʻai o nā mea hana ma 3.0%, e hoʻopilikia ana i ka pae holoʻokoʻa o nā kumukūʻai ex-hale hana o nā mea hana ʻoihana ma kahi o 2.45 mau helu pakeneka. Ma waena o lākou, ua emi nā kumukūʻai o ka ʻoihana mining ma 7.4%, ʻoiai ua emi nā kumukūʻai o ka ʻoihana mea maka a me ka ʻoihana hana ʻana ma 2.8%. Ma waena o nā kumukūʻai kūʻai o nā mea hana ʻoihana, ua emi nā kumukūʻai o nā mea maka kemika ma 7.3%, ua emi nā kumukūʻai o ka wahie a me nā huahana mana ma 7.0%, a ua emi ka ʻoihana huahana laholio a me ka palakiko ma 3.4%.
Ua hoʻomau ka emi ʻana o nā kumukūʻai o ka ʻoihana hana a me ka ʻoihana mea 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 hoʻohālikelike ʻia me ka mahina i hala. Mai ka manaʻo o nā ʻoihana i māhele ʻia, ua emi pū nā kumukūʻai o nā huahana plastik a me nā mea synthetic, a ua emi pū ka ʻokoʻa ma waena o nā mea ʻelua i hoʻohālikelike ʻia me ka mahina i hala. E like me ka nānā ʻana i nā wā i hala, ua hōʻea nā loaʻa ma hope i kahi kiʻekiʻe manawa a laila hoʻomaka e emi, e hōʻike ana ua hoʻomaka ka piʻi ʻana o nā kumukūʻai mea maka a me nā huahana, a ua lohi ke kaʻina hana hoʻōla o nā kumukūʻai huahana ma mua o nā mea maka. ʻO ke kumukūʻai o nā mea maka polyolefin e like me kēia. ʻO ka helu haʻahaʻa i ka hapa mua o ka makahiki e like paha me ka lalo o ka makahiki, a ma hope o kahi manawa hoʻonui, hoʻomaka ia e loli i kēlā me kēia manawa.
