I kēia manawa, ʻo ka hoʻohana nui ʻana o ka lalopolyethylenei loko o koʻu ʻāina he kiʻiʻoniʻoni, hoʻoheheʻe ʻia, paipu, hollow, kaha kiʻi uea, kaula, metallocene, uhi a me nā ʻano nui ʻē aʻe.
ʻO ka mea mua e lawe i ke kaumaha, ʻo ka hapa nui o ka hoʻohana ʻana i lalo he kiʻiʻoniʻoni.No ka ʻoihana huahana kiʻiʻoniʻoni, ʻo ke kumu nui ka kiʻiʻoniʻoni mahiʻai, kiʻiʻoniʻoni ʻenehana a me nā kiʻiʻoniʻoni hoʻopili huahana.Eia nō naʻe, i nā makahiki i hala iho nei, ua hoʻopilikia pinepine ʻia nā mea e like me ke kau ʻana i nā ʻeke plastik a me ka nāwaliwali mau ʻana o ka noi ma muli o ke ahulau, a ke kū nei lākou i kahi kūlana hilahila.E hoʻololi mālie ʻia ke koi no nā huahana kiʻiʻoniʻoni maʻamau me ka hoʻolaha ʻana o nā plastic degradable.Ke kū nei nā mea hana kiʻiʻoniʻoni he nui i nā hana ʻenehana ʻenehana, a ke ulu mālie nei lākou i nā kiʻi ʻoniʻoni recyclable me ka maikaʻi a me ka hana.Eia nō naʻe, ma muli o ka degradability o nā kiʻi ʻoniʻoni degradable, aia nā koi ikaika no ka ʻeke o waho, a i ʻole ke koi ʻana i nā kiʻi ʻoniʻoni waho e pono e mālama ʻia no ka manawa lōʻihi ma mua o ka wā degradation, a ʻaʻole hiki ke hoʻololi ʻia nā kiʻi ʻoniʻoni a me nā māla ʻē aʻe. no laila e hoʻohana mau ʻia nā huahana kiʻiʻoniʻoni.Ua noho ʻo ia ma ke ʻano he huahana nui ma lalo o ka polyethylene no ka manawa lōʻihi, akā hiki ke emi i ka ulu ʻai a me ka emi ʻana o ka hapa.
Eia kekahi, ʻo nā ʻoihana e like me ka hoʻoheheʻe ʻana, nā paipu, a me nā hollows e pili kokoke ana i ka hana ʻana a me ke ola e noho mau i nā huahana mea kūʻai nui ma lalo o ka polyethylene i nā makahiki e hiki mai ana, a e hoʻomau ʻia e nā ʻoihana, nā mea e pono ai i kēlā me kēia lā, a me nā mea hana kīwila. a me nā mea hana.Hoʻopili ʻia ke ola o ka poʻe i nā waiwai paʻa, a ua hoʻemi ʻia ke koi no ka hōʻemi ʻana i nā huahana.ʻO ka pilikia nui e kū nei i nā ʻoihana i luna aʻe i kēia manawa, ʻo ia ka piʻi ʻana o ka ulu ʻana o ka ʻoihana waiwai i nā makahiki i hala.Ma muli o nā kumu e like me nā manaʻo maikaʻi ʻole e pili ana i ka manaʻo ʻai o nā kamaʻāina i lawe ʻia e nā maʻi maʻi mau, ke kū nei ka hoʻomohala ʻana o ka ʻoihana huahana i kekahi kūʻē ulu.No laila, ʻoi aku ka liʻiliʻi o ka hoʻololi ʻana i ka manawa pōkole, ʻaʻole i hoʻopilikia ʻia e nā huahana degradation, ʻoi aku ka hopena o ka ʻoihana paipu e nā kulekele, ʻoiai ʻoi aku ka hopena o ka hoʻoheheʻe ʻana a me nā huahana hollow e ka manaʻo o ka poʻe noho, a me ka ulu ulu. e lohi ana no kekahi manawa i ka wā e hiki mai ana.
Me ka hoʻomau mau ʻana o ka ʻepekema a me ka ʻenehana, ʻo ka hoʻomohala ʻana a me ka hoʻomohala kanaka ʻana o nā huahana plastik, a me ka hoʻonui ʻana i ka maikaʻi o ka huahana a me nā koi hana maʻamau e ulu mau ana.No laila, i ka wā e hiki mai ana, e hoʻonui ka ʻoihana huahana plastic i ka noi no kekahi mau mea maka e hoʻomaikaʻi i ka hana o nā huahana plastic, e like me metallocenes, rolling plastics, coating material a me nā huahana kiʻekiʻe kiʻekiʻe a i ʻole nā huahana me nā koi kūikawā i nā kahua kūikawā. .Eia kekahi, ma muli o ka hana nui ʻana o nā ʻoihana hana polyethylene upstream i nā makahiki i hala iho nei, ka hopena i ka hoʻohuli ʻana o ka huahana koʻikoʻi, a me ka hakakā ma waena o Rūsia a me Ukraine i loko o ka makahiki i kumu ai ke kumukūʻai aila kiʻekiʻe e pana i ka waiwai o ka ethylene, a me ka piʻi ʻana o ke kumukūʻai. a ʻo ka hāʻawi ʻana i hopena i ka homogeneity huahana koʻikoʻi.Ma lalo o ke kūlana o kēia manawa, ua ʻoi aku ka ikaika o nā mea hana polyethylene i ka hana ʻana i nā huahana kiʻekiʻe e like me nā metallocenes, rotational molding, a me nā uhi, e like me ka hoʻomohala ʻana o nā ʻoihana o lalo.No laila, hiki ke hoʻonui ʻia ka ulu ʻana o nā huahana i kekahi ʻano i ka wā e hiki mai ana.
Eia kekahi, e like me ka hoʻomau pinepine ʻana o ka maʻi ahulau, a me ka noiʻi ʻana a me ka hoʻomohala ʻana i nā hōʻailona hou e nā mea hana, nā polyethylene fibers, nā lāʻau lapaʻau a me nā huahana pale i nā mea kūikawā hoʻi e hahai mālie ʻia a hoʻomohala ʻia, a e piʻi mau ka noi e hiki mai ana.
