Kuhi ʻia ka mākeke HDPE honua ma US $ 63.5 biliona ma 2017 a ke manaʻo ʻia nei e hōʻea i ka US $ 87.5 biliona e 2026, me ka nui o ka ulu ʻana o ka makahiki ma kahi o 4.32% i ka wā wānana.
ʻO ka polyethylene kiʻekiʻe (HDPE) he polymer thermoplastic i hana ʻia mai ka monomer ethylene i hana ʻia mai ke kinoea maoli, naphtha, a me ka aila kinoea.
ʻO ka HDPE he plastik maʻalahi, ʻoi aku ka opaque, ʻoi aku ka paʻakikī a hiki ke kū i nā wela kiʻekiʻe.Hiki ke hoʻohana ʻia ka HDPE i nā noi he nui a me nā ʻoihana e koi ana i ke kūpaʻa hopena ikaika, ka ikaika tensile maikaʻi loa, ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka pale kemika.
Wahi a nā noi ʻoihana, hiki ke hoʻokaʻawale ʻia ka mākeke HDPE i loko o nā pāpale hue a me nā ʻeke ʻeke, geomembranes, tapes, cross-linked polyethylene a me nā pepa.Manaʻo ʻia e hōʻike ʻo HDPE i ka koi kiʻekiʻe i kāna mau noi.
Ma muli o kona ʻala haʻahaʻa a me ke kūpaʻa kemika maikaʻi loa, kūpono loa ke kiʻi HDPE no ka hoʻohana ʻana i ka meaʻai.He mea kaulana loa ia i ka ʻoihana hoʻopili no ka mea ua hoʻohana nui ʻia ia e hana i nā huahana like ʻole, e like me nā pāpale omole, nā waihona meaʻai, nā ʻeke, etc. Bale.
ʻO ka HDPE ka helu no ka lua o ka hapa nui o ka koi paipu plastik a manaʻo ʻia e ulu ikaika loa i ka wā wānana.
ʻAʻole hiki ke hoʻokuʻu wale ʻia nā ʻōpala ʻole biodegradable mai kā mākou pae ʻāina, akā mālama pū kekahi i ka ikehu.Hiki i ka hana hou ʻana o HDPE ke mālama i ʻelua manawa o ka ikehu i hoʻohana ʻia i ka hana ʻana i ka plastik puʻupaʻa.Ke hoʻomau nei ka piʻi ʻana o ka nui o ka plastic recycling i nā ʻāina i kūkulu ʻia e like me United Kingdom, United States a me Kelemania, e manaʻo ʻia e hoʻonui ʻia ka noi no ka hoʻihoʻi hou ʻana o HDPE.
ʻO ka ʻāina ʻo ʻAsia-Pākīpika ka mākeke HDPE nui loa ma 2017 ma muli o ka ʻoihana paʻi nui ma ka ʻāina.Eia kekahi, i nā ʻāina e kū mai ana me India a me Kina, hoʻonui ʻia ka hoʻolilo ʻana o ke aupuni no ke kūkulu ʻana i nā ʻoihana e manaʻo ʻia e hāpai i ka ulu ʻana o ka mākeke HDPE i ka wā wānana.
Hāʻawi ka hōʻike i kahi loiloi piha o nā mea hoʻokele mākeke nui, nā kaohi, nā manawa kūpono, nā pilikia a me nā pilikia koʻikoʻi i ka mākeke.
