I tēnei wā, ko ngā whakamahinga matua o muri mai opolyethylenei tōku whenua ko te kiriata, te whakakoi werohanga, te paipa, te tuwhera, te tuhi waea, te taura, te metallocene, te paninga me ētahi atu momo matua.
Ko te tuatahi ki te pikau i te taumaha, ko te nui rawa o te kai o raro ko te kiriata. Mō te umanga hua kiriata, ko te kiriata ahuwhenua, te kiriata ahumahi me te kiriata tākai hua te mea matua. Heoi, i ngā tau tata nei, ko ngā āhuatanga pēnei i te here i runga i ngā putea kirihou me te ngoikore haere tonu o te tono nā te mate urutā kua maha tonu te whakararuraru i a rātou, ā, kei te anga atu rātou ki tētahi āhuatanga whakama. Ka whakakapia mārire te tono mō ngā hua kiriata kirihou tuku iho me te rongonui o ngā kirihou pirau. He maha ngā kaihanga kiriata kei te anga atu hoki ki ngā auahatanga hangarau ahumahi, ā, kei te whanake haere ki ngā kiriata ahumahi hangarua me te kounga me te mahi kaha ake. Heoi, nā te pirau o ngā kiriata kirihou pirau, he kaha ngā whakaritenga mō te tākai o waho, te tono rānei mō ngā kiriata tākai o waho me penapena mō te wā roa i tua atu i te wā pirau, ā, kāore tonu e taea te whakakapi i ngā kiriata ahumahi me ētahi atu mara, nō reira ka whakamahia tonutia ngā hua kiriata. Kua roa nei hei hua matua o raro i te polyethylene, engari tera pea ka puhoi te tipu o te kai me te heke o te ōwehenga.
Hei tāpiritanga, ko ngā ahumahi pēnei i te werohanga whakarewa, ngā paipa, me ngā kōhao e pā tata ana ki te hanga me te oranga ka noho tonu hei hua kaihoko matua i muri i te polyethylene i ngā tau torutoru e whai ake nei, ā, ka noho tonu te mana o ngā hanganga, ngā mea e hiahiatia ana i ia rā, me ngā taputapu me ngā taputapu ā-iwi. Ko te oranga o te tangata e pā ana ki ngā taonga pumau, ā, kua whakaitihia te hiahia mō te pirau hua. Ko te raruraru matua e pā ana ki ngā ahumahi o runga ake nei i tēnei wā ko te tere tipu o te rāngai hoko whenua kua kore e tupu i ngā tau tata nei. Nā ngā āhuatanga pēnei i te urupare kino ki te whakaaro kai a ngā kainoho i puta mai i ngā mate urutā maha, kei te anga atu te whanaketanga o te ahumahi hua ki te ātete tipu. Nō reira, he iti noa te huringa o te ōwehenga wā poto, he iti ake te pānga o ngā hua pirau, he nui ake te tūponotanga o te ahumahi paipa ki te pāngia e ngā kaupapa here, ko te werohanga whakarewa me ngā hua kōhao he nui ake te pānga o te whakaaro kai a ngā kainoho, ā, ka puhoi te tere tipu mō tētahi wā i roto i te wā e heke mai nei.
I te whanaketanga tonu o te pūtaiao me te hangarau, kei te whanake tonu te auahatanga takitahi me te auahatanga tangata o ngā hua kirihou, me te auahatanga kounga hua me ngā whakaritenga whakaputa ritenga. Nō reira, i te heke mai, ka piki ake te tono mō ētahi rauemi mata e whakapai ake ana i te mahi a ngā hua kirihou i roto i te umanga hua kirihou, pērā i te metallocenes, te kirihou hurihuri, ngā rauemi paninga me ētahi atu hua uara-tāpiri teitei, ngā hua rānei he whakaritenga ahurei i roto i ngā mara motuhake. Hei tāpiri, nā te kaha o te whakaputanga o ngā umanga whakaputa polyethylene i ngā tau tata nei, i hua ake ai he hurihanga hua nui, me te pakanga i waenganui i a Rūhia me Ukraine i te tau i hua ake ai te utu hinu teitei ki te pana i ngā hua o te ethylene i raro iho, ā, nā te pikinga o te utu me te tuku i hua ake ai te ōritetanga o te hua. I raro i te āhuatanga o nāianei, kei te kaha ake te mahi a ngā Kaihanga polyethylene ki te whakaputa i ngā hua uara-tāpiri teitei pērā i te metallocenes, te hanga hurihuri, me ngā paninga, i runga anō i te whanaketanga o ngā umanga o raro iho. Nō reira, ka piki ake pea te tere tipu o ngā hua ki tētahi taumata i te heke mai.
Hei tāpiritanga, i te haere tonu o te mate urutā, me te rangahau me te whakawhanake i ngā waitohu hou e ngā kaihanga, ka āta whaihia, ka whakawhanakehia hoki ngā muka polyethylene, ngā rauemi motuhake mō ngā hua hauora me te tiaki, ā, ka piki haere tonu te hiahia mō ngā rā kei te heke mai.
