I tēnei wā, he nui te rahinga o te polyethylene e whakamahia ana i tōku whenua, ā, he uaua te whakarōpūtanga o ngā momo o raro iho, ā, ko te nuinga ka hokona tika ki ngā kaihanga hua kirihou. Nō roto i te mekameka ahumahi o raro iho o te ethylene tēnei hua whakamutunga. I te taha o te pānga o te kukū o te kai ā-rohe, kāore i te taurite te rerekētanga o te tuku me te tono ā-rohe.
I te mea kua whānui haere te kaha whakaputa o ngā umanga whakaputa polyethylene o tōku whenua i ngā tau tata nei, kua tino piki ake te taha tuku. I taua wā anō, nā te whakapai tonu o te hanga me te paerewa oranga o ngā kainoho, kua piki haere tonu te hiahia mō rātou i ngā tau tata nei. Heoi, mai i te haurua tuarua o te tau 2021, kua kino, kua rerekē hoki te āhua o te ao. Nā te horapa o te mate urutā me ngā pakanga ā-rohe kua puta he kore taurite i roto i te pūnaha pūngao-pūtea o te ao. Ko te hinganga. Nā te piki haere o ngā āwangawanga i roto i te ōhanga whānui kua akiaki i ngā kare ā-roto o te kai a ngā kainoho ki tētahi taumata tupato. I raro i te āhua o nāianei, he nui ake ngā mōrearea me ngā wero e pā ana ki te whanaketanga o ngā hua polyethylene.
Ko te taupori me te whanaketanga ōhanga te mea e whakatau ana i te tohatoha o te kai PE. Mai i te tirohanga a ngā rohe kai o raro, ko Haina ki te Rawhiti, Haina ki te Tonga, me Haina ki te Raki ngā rohe kai matua mō te kai o raro o te polyethylene i tōku whenua, ā, ka noho tonu hei tuatoru o ngā rohe kai mō ngā wā roa e haere ake nei. Heoi, me te whakarewatanga tonu o ngā taputapu whakaputa hou a meake nei, e matapaetia ana ka whakaitihia te rerekētanga kai i roto i ngā rohe kai nui e toru ki tētahi taumata. E matapaetia ana ka pā nui tēnei ki te tauira tuku me te tono ā meake nei me te rere o ngā hua i roto i ngā rohe nui. He mea tika hoki kia whakahuatia ahakoa he iti ake te ōwehenga o te hiahia o raro i te rohe ki te hauauru i tō Haina ki te Rawhiti, Haina ki te Tonga, me Haina ki te Raki, e peia ana e ngā kaupapa here ā-rohe pēnei i te "One Belt, One Road" me te "Western Development", ka piki ake te kai o raro o te polyethylene i te rohe ki te hauauru a meake nei. He pikinga ake te tumanako, inā koa mō ngā hua tono hanganga e arahina ana e ngā paipa, ā, he mārama ake te hiahia mō ngā hua hanga werohanga me ngā hua hanga hurihuri i puta mai i te whakapai tonu i te kounga o te oranga.
Kātahi, mō ngā momo kai o te heke mai, he aha ngā tumanakohanga whanaketanga mō ngā momo polyethylene matua e hiahiatia ana i te heke mai?
I tēnei wā, ko ngā whakamahinga matua o te polyethylene i tōku whenua ko te kiriata, te whakakoi werohanga, te paipa, te hanga kōhao, te kukume waea, te taura, te hanga 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 āta whakakapia te tono mō ngā hua kiriata kirihou tuku iho ki te rongonui o ngā kirihou pirau. He maha ngā kaihanga kiriata kei te anga atu hoki ki ngā auahatanga hangarau ahumahi, ā, kei te āta 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. E hono ana te oranga o te tangata ki ngā taonga pumau, ā, kua heke te hiahia mō te pirau o ngā hua. I tēnei wā, ko te raruraru matua e pā ana ki ngā ahumahi o runga ake nei ko te tere tipu o te rāngai hoko whenua kua noho pūmau 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, ā, he iti ake te pānga o ngā hua pirau. He nui ake te tūponotanga ka pāngia te ahumahi paipa 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 a meake 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.
