Ua ʻōlelo ʻo Joerg Auffermann, ke poʻo o ka hui hoʻomohala pāʻoihana honua o BASF biopolymers: "ʻO nā pono kaiaola nui o nā plastic compostable e hiki mai i ka hopena o ko lākou ola ʻana, no ka mea, kōkua kēia mau huahana i ka hoʻololi ʻana i nā ʻōpala meaʻai mai nā pae ʻāina a i ʻole nā mea puhi ahi i loko o ka hana hou.
I nā makahiki, ua komo ka ʻoihana polyester biodegradable i nā noi ʻē aʻe ma mua o nā kiʻiʻoniʻoni lahilahi. I ka makahiki 2013, no ka laʻana, ua hoʻolauna ka hui kofe Swiss i nā capsules kofe i hana ʻia mai ka resin Basf Ecovio.
ʻO kahi mākeke e puka mai ana no nā mea Novamont he papa ʻaina biodegradable, hiki ke hoʻopili ʻia me nā mea olaola ʻē aʻe. Ua ʻōlelo ʻo Facco, ke hopu nei ka ʻoki ʻoki ma nā wahi e like me ʻEulopa i hala i nā lula e kaupalena ana i ka hoʻohana ʻana i nā plastics hoʻohana hoʻokahi.
Ke komo nei nā mea pāʻani PBAT hou o ʻAsia i ka mākeke i ka manaʻo o ka ulu ʻana o ke kaiapuni. Ma South Korea, ke kūkulu nei ʻo LG Chem i kahi mea kanu PBAT 50,000-tonne-per-year e hoʻomaka i ka hana ʻana ma 2024 ma ke ʻano he $2.2bn hoʻolālā hoʻokele waiwai ma Seosan. Ke hui nei ʻo SK Geo Centric (ʻo SK Global Chemical ma mua) a me Kolon Industries e kūkulu i kahi mea kanu PBAT 50,000-ton ma Seoul. Hāʻawi ʻo Kolon, kahi mea hana nylon a me polyester, i ka ʻenehana hana, ʻoiai ʻo SK e hoʻolako i nā mea maka.
ʻO ka holo gula PBAT ka mea nui loa ma Kina. ʻO OKCHEM, kahi mea hoʻolaha kemika Kina, ke manaʻo nei e piʻi ka hana PBAT ma Kina mai 150,000 tonnes i 2020 a i kahi 400,000 tonnes i 2022.
ʻIke ʻo Verbruggen i kekahi mau mea hoʻokele waiwai. Ma kekahi ʻaoʻao, ua piʻi hou ka noi no nā ʻano biopolymers āpau. Paʻa ka lako, no laila ke kiʻekiʻe ke kumukūʻai o PBAT a me PLA.
Eia kekahi, ua ʻōlelo ʻo Verbruggen, ua koi ke aupuni Kina i ka ʻāina e "ʻoi aku ka nui a me ka ikaika" i nā bioplastics. Ma mua o kēia makahiki, ua hoʻoholo ʻia ke kānāwai e pāpā ana i nā ʻeke kūʻai non-biodegradable, mauʻu a me nā ʻoki ʻoki.
Ua ʻōlelo ʻo Verbruggen he nani ka mākeke PBAT i nā mea hana kemika Kina. ʻAʻole paʻakikī ka ʻenehana, ʻoi loa no nā hui me ka ʻike i ka polyester.
ʻO ka hoʻohālikelike, ʻoi aku ka nui o ka PLA. Ma mua o ka hana ʻana i ka polymer, pono ka hui e ferment i ka lactic acid mai kahi kumu kō. Ua ʻike ʻo Verbruggen he "ke kōpaʻa" ʻo Kina a pono e lawe mai i nā kalapona. "ʻAʻole ʻo Kina kahi wahi maikaʻi e kūkulu ai i ka nui o ka hiki," wahi āna.
Ke mālama nei nā mea hana PBAT i kēia manawa me nā mea pāʻani Asia hou. Ma 2018, ua hoʻopau ʻo Novamont i kahi papahana e hoʻihoʻi hou i kahi hale hana PET ma Patrika, Italia, e hana i ka polyester biodegradable. Ua pālua ka papahana i kāna hana ʻana i ka polyester biodegradable i 100,000 tons i kēlā me kēia makahiki.
A ma 2016, wehe ʻo Novamont i kahi mea kanu e hana ai i ka butanediol mai ke kō me ka hoʻohana ʻana i ka ʻenehana fermentation i hoʻomohala ʻia e Genomatica. ʻO ka mea kanu 30,000 ton-a-makahiki ma Italia ʻo ia wale nō ke ʻano o ka honua.
Wahi a Facco, hiki i nā mea hana PBAT hou o Asia ke hana i kahi helu palena o nā lepili huahana no nā noi nui. "ʻAʻole paʻakikī." Ua ʻōlelo ʻo ia. ʻO Novamont, ma ka ʻokoʻa, e mālama i kāna hoʻolālā no ka lawelawe ʻana i nā mākeke loea.
Ua pane aku ʻo Basf i ke ʻano hana kūkulu PBAT ʻĀsia ma ke kūkulu ʻana i kahi mea kanu hou ma Kina, me ka laikini ʻana i kāna ʻenehana PBAT i ka hui Kina ʻo Tongcheng New Materials, e hoʻolālā ana e kūkulu i kahi hale hana 60,000-ton/makahiki ma Shanghai e 2022. E kūʻai aku ʻo Basf i ka mea kanu. huahana.
"Ke manaʻo ʻia nei ka hoʻomohala ʻana o ka mākeke maikaʻi me nā kānāwai hou e hiki mai ana a me nā lula e pili ana i ka hoʻohana ʻana i nā mea bioplastic i ka hoʻopili ʻana, mulling a me nā ʻeke," wahi a Auffermann. E ʻae ka mea kanu hou iā BASF e "hoʻokō i nā pono ulu o ka ʻāina mai ka pae kūloko."
"Ke manaʻo nei ka mākeke e hoʻomau i ka hoʻomohala maikaʻi ʻana me nā kānāwai hou e hiki mai ana a me nā lula e pili ana i ka hoʻohana ʻana i nā mea bioplastic i ka hoʻopili ʻana, mulling a me nā noi ʻeke," wahi a Auffermann. E ʻae ka hale hou i ka BASF e "hoʻokō i ka koi ulu ma ka ʻāina".
I nā huaʻōlelo ʻē aʻe, ʻo BASF, ka mea i hoʻokumu i ka PBAT ma kahi o ka hapahā o ke kenekulia i hala aku nei, e hopu ana i ka ulu ʻana o ka ʻoihana hou i ka lilo ʻana o ka polymer i mea waiwai nui.
