He pai mō te taiao te putea PE?

I ngā tau tata nei, kua noho te oranga tonutanga hei whakaaro nui mā ngā kaihoko me ngā ahumahi. Nā te piki haere o te āwangawanga mō te parahanga kirihou, kua tirotirohia ngā putea polyethylene (PE). I roto i tēnei tuhinga, ka tūhuratia e mātou te pai o ngā putea PE ki te taiao, ōna pānga ki te taiao, me te mea ka taea te kī he kōwhiringa oranga tonutanga.

He aha te putea PE?
He mea hanga ngā putea PE mai i te polyethylene, te kirihou e whakamahia whānuitia ana puta noa i te ao. E mōhiotia ana mō tōna pakari, tōna ngāwari, me tōna ātete ki te makuku, ā, e rongonui ai rātou i roto i ngā takai, hokohoko, me te rokiroki. He maha ngā āhua o ngā putea PE, tae atu ki ngā putea ziplock, ngā putea hoko kai, me ngā rauemi takai, ā, e paingia ana mō tōna utu whai hua me te watea.

Ngā Pānga ki te Taiao o ngā Pēke PE

Ka tīmata te pānga ki te taiao o ngā putea PE i te hanga. Ko te polyethylene i ahu mai i ngā wahie pūmua kore-whakahou, ko te hinu mata, ko te hau māori rānei te nuinga. He nui te pūngao e pau ana i te tukanga hanga, ā, ka puta he tukunga waro, ka whai wāhi ki te mahana o te ao. Heoi, he mama ake ngā putea PE, ā, he iti ake ngā rauemi e hiahiatia ana i te nuinga o ngā momo kē atu, ka whakaiti i te whakapaunga pūngao whānui ki te whakataurite ki ngā hua matotoru, taumaha ake pērā i ngā putea pepa, ngā putea kakahu rānei ka taea te whakamahi anō.

Te Reiti Pirau me te Pānga ki te Pūnaha Rauropi
Ko tētahi o ngā āwangawanga matua mō ngā putea PE ko tōna roa ki te taiao. Kāore e tere te pirau o ngā putea PE; i roto i ngā whenua ururua, ka roa pea ngā rau tau ka pakaru nā te kore o te rā me te hāora. I roto i ngā taiao tūturu, pērā i ngā moana me ngā ngahere, ka taea e rātou te pakaru hei kirihou moroiti, ka tū hei mōrearea ki ngā kararehe mohoao ka horomia, ka mau rānei ki roto i te rauemi. Ka whai wāhi tēnei pirau puhoi ki te parahanga kirihou, he take nui tēnei mō te taiao.

Te āheinga ki te hangarua i ngā putea PE
Ka taea te hangarua anō i ngā putea PE, engari he iti noa iho te auau hangarua ki te whakataurite ki ētahi atu rauemi. He maha ngā kaupapa hangarua taha-rori kāore e whakaae ana ki ngā putea PE nā te mea ka ārai i ngā mīhini whakarōpū. Heoi, he maha ngā toa me ngā pokapū hangarua motuhake e whakaae ana ki ēnei putea hei hangarua, ka taea ai te whakamahi anō hei hua kirihou hou pēnei i te rakau hiato, i ngā putea hou rānei. Mā te whakapiki ake i te mōhiotanga me ngā whakapainga ki ngā hanganga hangarua ka taea te whakaiti i te taumahatanga taiao o ngā putea PE.

He aha te whakataurite o ngā putea PE ki ētahi atu putea?
Ina whakatauritea te pānga taiao o ngā putea PE ki ngā momo kirihou rerekē pērā i te pepa, i ētahi atu momo kirihou rānei, he rerekē ngā hua. Ahakoa he pirau ngā putea pepa, me nui ake te pūngao me te wai hei whakaputa. E whakaatu ana ngā rangahau he nui ake te tapuwae waro o ngā putea pepa nā ngā rauemi e hiahiatia ana mō te whakatipu rākau, te hanga, me te kawe waka. I tētahi atu taha, ko ngā putea kirihou matotoru ake ka taea te whakamahi anō (he maha ngā wā ka hangaia mai i te polypropylene) me ngā putea kakahu me maha ngā whakamahinga hei whakakore i ō rātou pānga whakaputa nui ake. Ahakoa ō rātou ngoikoretanga, he iti ake te tapuwae tīmatanga o ngā putea PE engari kāore i te tino pai ki te taiao mena ka mutu ki te taiao kaua ki te hangarua.

Rangahau me ngā Tatauranga
I roto i tētahi rangahau i te tau 2018 a te Manatū Taiao me te Kai o Tenemāka, i whakaritea ngā aromatawai huringa ora o ngā momo putea hokohoko rerekē. I kitea ko ngā putea PE te iti rawa o te pānga ki te taiao e pā ana ki te whakamahinga wai, te whakamahinga pūngao, me ngā tukunga hau kati kōtuhi ina whakamahia anōtia i ngā wā maha, ina hangarua rānei. Heoi, i whakanuia anō hoki e te rangahau te hiranga o te whakakorenga tika hei whakaiti i te tūponotanga o te parahanga. E whakaatu ana ēnei raraunga ahakoa kāore ngā putea PE i te kore utu taiao, he kōwhiringa pumau ake pea i ētahi atu momo putea i roto i ētahi horopaki, inā koa ka hangarua.

Whakamutunga
He pai, he kino hoki ngā putea PE mō te taiao, pērā i ngā hua kirihou katoa. Nā te iti o te utu whakaputa, te ngāwari ki te hangarua, me te maha o ngā whakamahinga, he mea whai hua ēnei putea, engari he āwangawanga nui te roa o te pirau me te whai wāhi pea ki te parahanga kirihou. Mā te whakanui ake i ngā tere hangarua, te whakatenatena i te whakakorenga tika, me te whiriwhiri i ngā huarahi pai mō te taiao i ngā wā e taea ai, ka taea e ngā kaihoko te āwhina ki te whakaiti i te pānga taiao o ngā putea PE. Pērā i ngā rauemi katoa, ko te kī ki te pumau kei roto i te mārama ki te huringa ora katoa me te whakatau whai whakaaro.

Mō ētahi atu kōrero mō te pānga o ngā kirihou ki te taiao, me pēhea hoki te whakaiti i ngā para kirihou, whakaarohia te pānui i ngā rauemi mai i teTe Tari Tiaki Taiao.
