1. No ka ʻoihana hana ka ʻoihana kemika maikaʻi a he kiʻekiʻe kona pilina ʻoihana me nā ʻoihana ʻē aʻe
ʻO nā ʻoihana e pili loa ana i ka ʻoihana kemika maikaʻi, ʻo ia hoʻi: ka mahiʻai, ka lole, ke kūkulu ʻana, ka ʻoihana pepa, ka ʻoihana meaʻai, ka hana kemika o kēlā me kēia lā, nā lako uila, a pēlā aku. ʻO ka hoʻomohala ʻana o ka ʻoihana kemika maikaʻi e pili loa ana i kēia mau ʻoihana.
ʻO ka ʻaoʻao luna o ka ʻoihana kemika maikaʻi ka hana ʻana i nā mea maka kemika kumu; i ka manawa like, ʻo nā huahana i hāʻawi ʻia e ka ʻoihana kemika maikaʻi nā mea maka kumu no nā ʻoihana ʻē aʻe he nui, e like me ka mahiʻai, ke kūkulu ʻana, nā lole, nā lāʻau lapaʻau a me nā ʻoihana koʻikoʻi ʻē aʻe. ʻO ka hoʻomohala ʻana i ka mahiʻai, ke kūkulu ʻana, ka lole, nā lāʻau lapaʻau, nā mea uila a me nā ʻoihana pili ʻē aʻe e hāʻawi i nā manawa hoʻomohala no ka hoʻomohala ʻana i ka ʻoihana kemika maikaʻi; i ka manawa like, ʻo ka hoʻomohala ʻana i ka ʻoihana kemika maikaʻi e paipai pū i ka hoʻomohala ʻana o nā ʻoihana luna.
2. Loaʻa i ka ʻoihana kemika maikaʻi kekahi mau ʻano o nā hoʻokele waiwai o ka unahi
ʻOi aku ka nui o ka hana ʻana o nā ʻoihana hana kemika maikaʻi ma waho ma mua o 100,000 tone. I ka hapalua ʻelua o ke kenekulia 20, ua hōʻike ʻia nā ʻoihana hana kemika maikaʻi honua e ʻAmelika Hui Pū ʻIa a me Iapana, e hōʻike ana i nā ʻano o ka nui a me ka loea, i mea e hoʻemi mau ai i nā kumukūʻai hana. I kēia manawa, ua haʻahaʻa ka nui o ka ʻoihana kemika maikaʻi o koʻu ʻāina, me ka hapa nui o nā ʻoihana liʻiliʻi, ʻoiai ʻo ka hapa o nā ʻoihana waena a me nā ʻoihana nui, ʻoi aku ka nui o nā ʻoihana nui, ua haʻahaʻa.
3. ʻO ka ʻoihana kemika maikaʻi he ʻoihana me nā hoʻokuʻu kiʻekiʻe o nā mea haumia ʻoihana
Wahi a ka Hōʻike Makahiki ʻIkepili Kaiapuni 2012, ʻo ka hoʻokuʻu ʻana o ka wai ʻino o ka ʻoihana kemika he 16.3% o ka hoʻokuʻu ʻana o ka wai ʻino o ka ʻoihana aupuni, ʻo ia ka lua; ʻo ka hoʻokuʻu ʻana o ke kinoea hoʻopau he 6% o ka hoʻokuʻu ʻana o ka ʻoihana aupuni, ʻo ia ka hā; ʻo ka hoʻokuʻu ʻana o ka ʻōpala paʻa he 5% ia o ka hoʻokuʻu ʻana o ka ʻōpala paʻa o ka ʻāina, ʻo ia ka ʻelima; ʻO ka hoʻokuʻu ʻana o ka COD he 11.7% o ka huina o ka hoʻokuʻu ʻana o ka COD ʻoihana o ka ʻāina, ʻo ia ka ʻekolu.
4. Nā ʻano o ka ʻoihana i kēlā me kēia manawa
ʻO nā ʻoihana ma hope e kū nei i ka ʻoihana kemika maikaʻi e komo pū ana me nā plasticizers kaiapuni, nā uhi pauka, nā mea hoʻokaʻawale, nā mea hoʻōla wela kiʻekiʻe a me nā ʻoihana ʻē aʻe. Hoʻohana ʻia nā huahana hope loa i nā huahana plastik like ʻole, nā mea kūkulu hale, nā mea hoʻopili, nā lako hale, nā mīkini kaʻa, a me nā mea ʻē aʻe, e uhi ana i nā wahi he nui o ka hoʻokele waiwai aupuni, ʻaʻole ʻike ʻia nā ʻano cyclical o ka ʻoihana ponoʻī, akā ma muli o ka hopena o ka hoʻokele waiwai macro, e hōʻike ia i kekahi mau fluctuations i ka wā e loli ai ke kūlana hoʻokele waiwai holoʻokoʻa. ʻO ke kaʻina hana o ka ʻoihana ua like ia me ke kaʻina hana o ka hana macroeconomic holoʻokoʻa.
5. Nā ʻano ʻāpana o ka ʻoihana
Mai ka manaʻo o ka hoʻolaha ʻāina ʻana o nā ʻoihana ʻoihana kemika maikaʻi o koʻu ʻāina, ua maopopo ka ʻano ʻāina o nā ʻoihana i ka ʻoihana kemika maikaʻi, ʻo East China ka hapa nui loa a ʻo North China ka lua.
6. Nā ʻano kau o ka ʻoihana
He ākea loa nā kahua noi ma hope o ka ʻoihana kemika maikaʻi, a ʻaʻohe hiʻohiʻona kau maopopo ma ke ʻano laulā.
