ʻOmole plastik HDPE
ʻO nā ʻōmole plastik kiʻekiʻe kiʻekiʻe (HDPE) kahi koho hoʻopili kaulana no ka mākeke waiū a me nā wai wai hou.Ma UK, no ka laʻana, ma kahi o 4 biliona mau ʻōmole hānai HDPE i hana ʻia a kūʻai ʻia i kēlā me kēia makahiki.

Hāʻawi ʻo HDPE i nā pono he nui i nā mea hana, nā mea kūʻai aku a me nā mea kūʻai aku.

Nā pōmaikaʻi o nā ʻōmole HDPE
Hiki ke hoʻohana hou ʻia: ʻO nā hue HDPE he 100% recyclable, no laila hiki ke hoʻohana hou ʻia ka mea

Hoʻomau: Hāʻawi ʻo HDPE i ka manawa e hoʻohui hou i nā mea hana hou i loko o ke kaulahao lako

Māmā Māmā: Hāʻawi nā ʻOmole HDPE i nā manawa māmā

Hiki ke hoʻololi ʻia: ʻo ka hue plastik wale nō i hiki ke hoʻohana ʻia e like me ka monolayer waiū pasteurized, a i ʻole he UHT a i ʻole ka waiu waiu sterilized co-extruded bottle

ʻO ka maʻalahi o ka hoʻohana ʻana: ʻO ke ʻano wale nō o ka puʻupuʻu e hiki ai i nā lima i hoʻohui ʻia a ninini i nā lua no ka hoʻopaʻa ʻia ʻana a me ka ninini ʻana

ʻO nā hue pēpē HDPE kekahi o nā mea hoʻopihapiha hoʻopihapiha nui loa ma UK, me ka ʻikepili mai Recoup e hōʻike ana ma kahi o 79% o nā hue pēpē HDPE e hana hou ʻia.
Ma ka awelika,Nā ʻōmole HDPEma UK i kēia manawa he 15% māmā ma mua o ʻekolu makahiki i hala

Eia nō naʻe, ʻo nā hoʻolālā hou e like me ka ʻōmole Infini lanakila i ka makana i kēia manawa hiki ke hoʻemi i ke kaumaha o nā hue maʻamau a hiki i ka 25% (ma muli o ka nui)

Ma ka awelika, loaʻa nā hue HDPE ma UK a hiki i ka 15% mea hana hou

Eia nō naʻe, ʻo ka holomua o ka ʻenehana a me nā hoʻolālā hou o nā huahana ke manaʻo nei ua hiki i nā hoʻokō hou.No ka laʻana, i ka makahiki 2013, ua hoʻohui ʻo Nampak i 30 pākēneka i hoʻohana hou ʻia HDPE i kāna mau hue waiu Infini, kahi honua mua-ʻelua makahiki ma mua o ka pahuhopu ʻoihana.
