Manaʻo ʻia e hoʻomau kēia ʻano iho, ma muli o ka emi ʻana o ke koi, ka emi ʻana o nā kumukūʻai maka a me ka lawa ʻana o ka lako. #revaluation
I ke komo ʻana i ka hapaha ʻehā, ua hoʻomau ka hāʻule ʻana o nā kumukūʻai PE, PP, PS, PVC a me PET mai Iulai mai, i hoʻokele ʻia e ka lohi o ke koi, ka lako lawa, ka emi ʻana o nā kumukūʻai maka a me ka maopopo ʻole o ka hoʻokele waiwai honua. I ke ʻano o ka polyethylene a me ka polypropylene, ʻo ke kauoha ʻana i kahi mana hou koʻikoʻi kekahi kumu ʻē aʻe, ʻoiai ʻo nā mea lawe mai me ke kumukūʻai hoʻokūkū he pilikia ia no PET a me ka polystyrene paha.
Eia ka manaʻo o Michael Greenberg, Luna Kūkākūkā Kūʻai ma Resin Technology, Inc. (RTi), Luna Hoʻoponopono Kiʻekiʻe ma PetroChemWire (PCW), Luna Nui o The Plastics Exchange, a me Scott Newell, EVP Polyolefins ma ka mea hoʻolaha resin a me ka mea hoʻohuihui Spartan Polymers.
ʻOiai ua hoʻolaha nā mea hoʻolako polyethylene i ka hoʻonui ʻia ʻana o ke kumukūʻai o 5-7 keneta no ka paona i Kepakemapa-ʻOkakopa, ua hāʻule nā ​​​​kumukūʻai polyethylene ma ka liʻiliʻi he 4 keneta a i 6 keneta no ka paona i ʻAukake a ke manaʻo ʻia nei e hāʻule hou aʻe i Kepakemapa, wahi a David Barry. . Luna Hoʻokele Hope o PCW o Polyethylene, Polystyrene, a me Polystyrene ʻo Robin Chesshire, Hope Pelekikena RTi o Polyethylene, Polystyrene, a me Nylon-6 Markets, a me Greenberg o Plastics Exchange. Akā, manaʻoʻiʻo kēia mau kumu e hāʻule iki nā kumukūʻai i ʻOkakopa a me kēia mahina.
Ua ʻōlelo ʻo Chesshire o RTi ua ikaika mau ke koi no ka polyethylene no ka hapa nui o ka makahiki, akā i ka hopena o Kepakemapa ua emi iho ia ma ka hapa nui o nā ʻāpana mākeke. Ua ʻōlelo ʻo Barry o PCW ʻaʻole e hoʻokiʻekiʻe ke kumukūʻai o nā mea maka, ʻaʻohe hōʻailona o ka piʻi ʻana o ke koi a me ka wehe ʻana o kahi mana nui hou mai Shell. Ua ʻōlelo pū ʻo ia ua hāʻule nā ​​​​kumukūʻai kiko polyethylene i 4 keneta a i 7 keneta i ka paona e like me Kepakemapa: "Ke nāwaliwali nei ke koi hoʻokuʻu aku, he nui nā waihona o nā mea kālepa, a aia ka kānalua e pili ana i nā neʻe kumukūʻai i ka mahina e hiki mai ana. ʻaneʻane paʻa iki ia i ka wā e manaʻo ai nā mea kūʻai aku i nā hōʻemi kumukūʻai e hiki mai ana."
Ua ʻike pū nā kumu ua hoʻemi nā mea hoʻolako i ka hana ʻana. I ʻOkakopa, ua wehewehe ʻo Greenberg i ka mākeke kiko: "Ke kūʻai mau nei ka hapa nui o nā mea hana i ka resin e like me ka mea e pono ai, a ke hoʻomaka nei kekahi mau mea hana e kūʻai hou aku i ka resin i ka wā e kūpono ai nā kumukūʻai, ʻoiai ua lohi ka noi o nā mea kūʻai aku ma nā ʻoihana ma lalo o ka nui ma muli o nā kūlana hoʻokele waiwai a me ka hoʻokele waiwai. Hopohopo ka inflation Ke hoʻomau nei nā mea hana a me nā mea hoʻolako resin nui ʻē aʻe i ka hoʻowahāwahā i nā kumukūʻai haʻahaʻa i ka wā e hoʻohuli ai ke ʻano bearish, me nā helu hana haʻahaʻa a me nā kumukūʻai kiʻekiʻe ma Asia, ma ke kuhi ʻana ua kōkua kēia i ka hoʻomaikaʻi ʻana i ka noi kūloko i ka wā i hōʻike ai kekahi poʻe kūʻai i ka hopohopo e pili ana i nā loaʻa kālā i nalowale. nā kuʻikahi nui a me nā kumukūʻai mālama haʻahaʻa."
Ua hāʻule nā ​​kumukūʻai Polypropylene i 1 keneta/lb i ʻAukake, ʻoiai ua piʻi aʻe nā kumukūʻai propylene monomer i 2 keneta/lb, akā ua hāʻule nā ​​​​​​ka palena o nā mea hoʻolako i 3 keneta. Wahi a Barry o PCW, ʻo Newell o Spartan Polymers lāua ʻo The Plastic Exchange, ua hāʻule nā ​​​​kumukūʻai o Kepakemapa no ka polypropylene i ka huina o 8 keneta i ka paona, ua hāʻule nā ​​​​kumukūʻai hoʻonā no nā ʻaelike monomer i 5 keneta i ka paona, a ua nalowale nā ​​​​​​mea hoʻolako i 3 keneta hou aʻe ma muli o nā palena haʻahaʻa. lb. Greenberg. Eia kekahi, manaʻoʻiʻo kēia mau kumu e hāʻule hou paha nā kumukūʻai i ʻOkakopa, ʻoiai ʻaʻole i loli a emi paha nā kumukūʻai i kēia mahina.
ʻIke ʻo Barry i kahi emi ʻana o ka helu pālua i ʻOkakopa, e hōʻike ana i ka emi ʻana o ke koi a me ka lako nui. No kēia mahina, ʻike ʻo ia i ka hiki ke emi hou aku i ka wā e hoʻomaka ai ʻo Exxon Mobil i kahi hale hana polypropylene hou a hoʻonui ʻo Heartland Polymer i ka hana ʻana ma kāna hale hana hou. Manaʻo ʻo Newell e hāʻule nā ​​​​kumukūʻai propylene monomer i 5 keneta a i 8 keneta i ka paona ma muli o ka haʻahaʻa o nā kumukūʻai kiko honua. Hoʻoweliweli ʻo ia i kahi emi hou ʻana o ka loaʻa kālā. Ua ʻōlelo ʻo ia e manaʻo ʻia nā mea hoʻolako polypropylene e hōʻemi i ka hana ma muli o kahi keu £175m i Iulai-ʻAukake i ka wā e emi ai ke koi. Ua piʻi ka nui o nā lā lawe i 40 mau lā i Kepakemapa i hoʻohālikelike ʻia me nā lā 30-31 maʻamau i kahi mākeke kaulike. Ua hōʻike kēia mau kumu i nā uku hoʻēmi o 10 a 20 keneta no ka paona i hoʻohālikelike ʻia me nā kumukūʻai mākeke kiko.
Ua wehewehe ʻo Greenberg i ka mākeke kiko PP he lohi i ka hoʻomau ʻana o ke koi nāwaliwali i ʻOkakopa a ua hoʻopili ʻo ia i kēia i ka lohi o ka hoʻokele waiwai honua, ka maopopo ʻole o ka hoʻokele waiwai pōkole, ka nui o ka hana resin a me nā mea kūʻai aku e hoʻoikaika ana i ko lākou mau ʻiʻo i nā kūkākūkā. "Inā hoʻomau nā mea hana e alakaʻi a lanakila i nā kauoha ma o nā hoʻololi kaulike, ma mua o ka hoʻolohi wale ʻana i ka hana e kaulike i ka lako a me ke koi, e ʻike paha mākou i nā emi ʻana o ka margin i ka wā e hiki mai ana."
Ma hope o ka hāʻule ʻana o 22 keneta i 25 keneta i ka paona i ʻAukake, ua hāʻule nā ​​​​kumukūʻai polystyrene he 11 keneta i ka paona i Kepakemapa, me Barry o PCW a me Chesshire o RTi e manaʻo nei e emi hou aʻe i ʻOkakopa a me ka mahina hoʻokahi. Ua ʻōlelo ka mea hope ua emi ka emi ʻana o PS i Kepakemapa ma mua o ka emi ʻana o 14c/lb i nā kumukūʻai o nā mea maka, a kuhikuhi i ka hoʻomau ʻana o ka lohi o ke koi a me ka emi ʻana o nā kumukūʻai o nā mea maka e kākoʻo ana i nā emi hou aʻe, me ka pale ʻana i nā hoʻopilikia nui o ka hana ʻana.
He manaʻo like ko Barry mai PCW. Ua piʻi aʻe ke kumukūʻai o ka Polystyrene he 53 keneta i ka paona mai Pepeluali akā ua hāʻule he 36 keneta i ka paona i ka hoʻomaka ʻana o ka hapaha ʻehā, wahi āna. ʻIke ʻo ia i kahi ākea no nā hōʻemi hou aʻe, me ka ʻōlelo ʻana e pono paha nā mea hoʻolako e hōʻemi hou aku i ka hana ʻana o ka styrene monomer a me ka polystyrene resin.
Ua ʻōlelo pū ʻo ia ʻoiai ʻo ka lawe ʻana mai o ka polystyrene resin ma kahi o 5% o nā lako i loaʻa, ua neʻe aku nā mea lawe mai o ka polystyrene resin mai ʻĀsia mai i kēia ʻāpana o ka honua, ʻo ia hoʻi i ʻAmelika Latina, ʻoiai ua emi loa nā kumukūʻai ukana. "Inā he pilikia kēia no nā mea hoʻolako polystyrene ʻAmelika ʻĀkau, e ʻike ʻia ana," wahi āna.
Wahi a Mark Kallman, ka hope pelekikena o RTi o PVC a me nā resins ʻenekinia, a me Donna Todd, ka mea hoʻoponopono kiʻekiʻe ma PCW, ua hāʻule nā ​​​​kumukūʻai PVC he 5 keneta no ka paona i ʻAukake a me 5 keneta hou no ka paona i Kepakemapa, e lawe ana i ka huina o ka emi ʻana i 15 keneta no ka paona. i ka hapaha ʻekolu. . Ua ʻike paha ʻo Kalman i kahi emi like i ʻOkakopa a me kēia mahina. ʻO nā mea kōkua e pili ana i ka lohi mau o ke koi mai Mei, ka lako nui ma ka mākeke a me nā pālahalaha nui ma waena o nā kumukūʻai hoʻokuʻu aku a me nā kumukūʻai kūloko.
Ua ʻōlelo ʻo Todd o PCW ʻo ia emi nui ʻana o nā kumukūʻai i loko o ia manawa pōkole he mea i ʻike mua ʻole ʻia ma ka mākeke PVC, a ua manaʻolana ka nui o nā mea komo mākeke ʻaʻole e hāʻule nā ​​​​kumukūʻai PVC i ka hapaha mua o 2023, e like me ka wānana a kekahi loea mākeke. . . . I ka hoʻomaka ʻana o ʻOkakopa, ua hōʻike ʻo ia "ʻOiai makemake nā mea hana paipu PVC e ʻike i nā kumukūʻai resin haʻahaʻa, ʻo ka hāʻule ʻana o nā kumukūʻai PVC e like me ke kaʻaahi ukana holo e uku maoli iā lākou i ke kālā i ka wā e hoʻohaʻahaʻa ai nā kumukūʻai resin i nā kumukūʻai paipu. I kekahi mau hihia, ua hoʻemi ʻia nā kumukūʻai paipu. hāʻule wikiwiki ma mua o nā kumukūʻai resin. ʻO nā mea hana hou ma nā mākeke ʻē aʻe, e like me ka ʻaoʻao a me ka papahele, aia ma kēlā ʻaoʻao o ka hoʻohālikelike no ka mea ʻaʻole hiki i kēia mau mākeke ke hoʻouna i ka piʻi piha ʻana o nā kumukūʻai resin i kā lākou mea kūʻai aku. Ua hauʻoli lākou i ka ʻike ʻana i ka hāʻule ʻana o nā kumukūʻai i ka hikiwawe loa, no laila e hoʻihoʻi ana i kā lākou ʻoihana i kekahi pae o ka loaʻa kālā.
Ua hāʻule nā ​​kumukūʻai PET i 2 keneta a i 3 keneta/lb i Kepakemapa ma hope o ka hāʻule ʻana o 20 keneta/lb i Iulai-ʻAukake, ma muli o ka emi ʻana o nā kumukūʻai o nā mea maka. Manaʻo ʻo Cullman o RTi e hāʻule hou nā kumukūʻai i 2-3 keneta i ka paona i ʻOkakopa, me nā kumukūʻai paʻa a haʻahaʻa iki paha i ka mahina. Maikaʻi nō ke koi, akā ua lako pono ka mākeke kūloko a ke hoʻomau nei nā mea i hoʻokuʻu ʻia aku i ke kahe ʻana ma nā kumukūʻai hoihoi, wahi āna.
ʻO nā mea e pili ana i ke koi ikaika kūloko a/a i ʻole ke koi aku i waho, nā waihona mea hoʻolako palena a me ke kumukūʻai kiʻekiʻe o nā mea maka ma muli o nā hoʻopilikia hana ʻana.
