Nānā i nā mea hoʻohui palaki

ʻO nā mea hoʻohui plastik he mau pūhui pono e hoʻohui ʻia i ka wā o ke kaʻina hana o nā polymers (synthetic resins) e hoʻomaikaʻi i kā lākou hana hana a i ʻole e hoʻomaikaʻi i nā waiwai ponoʻī o ka resin.

Pāʻani koʻikoʻi nā mea hoʻohui plastik i ka hana ʻana i ka plastic.ʻO nā mea hoʻohui maʻamau ka plasticizers, heat stabilizers, antioxidants, light stabilizers, flame retardants, foaming agents, anti-static agents, kala.nā ʻanuʻu, nā mea hoʻomālamalama maka, nā mea hoʻopihapiha, nā mea hoʻohui, nā lubricants, nā mea hoʻokuʻu, nā mea nucleating, etc.

Ke hoʻonui mau nei ka hoʻohana ʻana i nā mea hoʻohui plastik ma Kina, a ua piʻi nui nā ʻano huahana. Ua lilo ka ʻoihana additive plastic i ʻoihana koʻikoʻi me kahi ʻano piha piha o nā ʻano a me nā ʻano huahana like ʻole. Ua holomua nui ʻo ia ma ke ʻano o ka pae ʻenehana, ka hoʻolālā huahana, ka pae hana, a me ka maikaʻi o nā limahana ʻepekema a me ka ʻenehana, e hoʻokō pono ana i ka noi o ka ʻoihana o lalo no nā huahana additive plastic. Ke hele mālie nei ka waiwai o Kina i waho.

I kēia manawa, ʻo ke kumu nui o ka mākeke plastik o Kina ka piʻi ʻana o ka noi ma nā kahua o nā kaʻa ikehu hou (mau mea māmā), nā uila a me nā mea hana (nā ʻāpana kiʻekiʻe), ka pale biodegradable a pēlā aku. Eia nō naʻe, ʻo nā mea paʻa i ka plastic a me nā kulekele pāpā i nā mea hoʻohui ʻawaʻawa (e like me ke alakaʻi i loaʻa nā stabilizers) ma nā ʻāina like ʻole e hāpai i ka noiʻi a me ka hoʻomohala ʻana i nā ʻano ʻōmaʻomaʻo.

Hāʻawi kā mākou ʻoihana i nā pūʻulu piha o nā mea hoʻohui plastik, e pili ana i ka substrate o ka mea kūʻai aku a me ka ʻenehana hana. E leka uila iā mākou ma ka leka uila, a e pane mākou iā ʻoe i loko o 48 mau hola.
