He wāhi anō kei reira hei whakarerekētanga iho i ngā utu CPE?

I te haurua tuatahi o 2021-2022, i piki ake ngā utu CPE, ā, ko te mea tino teitei rawa atu tēnei i roto i te hītori. I te 22 o Hune, i heke iho ngā ota tuku iho, ā, i āta puta ake te pēhanga kaipuke o ngā kaihanga polyethylene chlorinated (CPE), ā, i paku whakarerekētia te utu. I te tīmatanga o Hūrae, ko te hekenga he 9.1%.

Mō te ia o te mākete i ngā wā o muri mai, he tokomaha ngā tāngata o roto i te umanga e whakapono ana tera pea ka heke te utu o te mākete CPE mō te wā poto i raro i te awe o ngā āhuatanga kino pēnei i te hekenga o te utu o ngā rauemi mata, te wai chlorine, te hekenga o te utu, te ngoikore o te tono ā-rohe me tāwāhi, me te kore e ranea ngā ota o muri mai hei whai ake, me te nui o ngā taonga a ngā kaihanga.

Ko tētahi o ngā tino take mō te tere o te hekenga o te polyethylene chlorinated (CPE) ko te panonitanga o te taha utu. Ko te chlorine wai te 30% o te utu o te CPE. Mai i te marama o Hune, kua rawaka ngā rahui o te chlorine wai, ā, kua ngoikore ngā utu o te nuinga o ngā hua o muri mai, ā, kua kore e pai te hua o ētahi hua, ā, kua heke te tono mō te chlorine wai, ā, kua heke tonu te utu o te chlorine wai, ā, kua heke haere tonu te utu o te CPE.

I te 22 o Hūrae, i whakamahere ngā umanga chlor-alkali ki te whakaiti i te tiaki, ā, kei te whakamahere ētahi kaha whakaputa hou ki te tīmata i te whakaputa. Heoi, kei te wā kore utu te whakamahinga chlorine i raro iho, ā, kāore i te tino kaha te hoko. Kei te heke tonu te mākete chlorine wai, ā, he uaua ki te whakapiki ake i ngā utu CPE i te taha utu.

He ngoikore te tono mō te CPE i raro i te whenua, he iti iho te tere whakahaere o ngā umanga i raro i te whenua, kua āraia hoki te tuku o ngā umanga PVC, kua roa te pupuri taonga, ā, kei te tere te heke o te utu o te mākete PVC. Kei te mau tonu te tono pakari a ngā kamupene PVC matua o raro i te whenua me ngā kamupene paipa PVC o te motu mō ngā hoko CPE, ā, he iti te hiahia ki te whakakī anō i ā rātou tūranga; kua heke anō hoki ngā ota kaweake ki tāwāhi i whakaritea ki tērā tau. Nā te ngoikore o te tono ā-roto, ā-waho hoki, kua puhoi te rere o te tuku CPE me te nui o ngā taonga.

I te nuinga o te wā, i raro i te taha ngoikore o te tono, kāore te pēhanga tuku CPE wā poto e heke. E matapaetia ana ka whakaatu te mākete i tētahi ia ngoikore haere, ā, tera pea ka heke tonu te utu.
