Ko te āhua o te taiao o te ao e hiahia ana kia whakamahia e tātou ngā rauemi me ngā para i runga i te whakaaro nui me te kawenga. Kei te rongonui haere ngā putea PEVA hei whakakapi i ngā putea polyethylene me ngā putea pepa tuku iho. He mea nui ngā take e pā ana ki tōna pānga ki te taiao ki ngā tohunga me ngā kaihoko noa. I roto i tēnei tuhinga, ka whakaarohia e tātou te pānga o ngā putea PEVA ki te taiao, ōna painga me ōna ngoikoretanga, me ngā mahi ka taea te mahi hei whakaiti i ōna pānga kino. He mea nui ēnei āhuatanga hei mārama ki te tūranga o ngā putea PEVA i te ao hou, hei whakatau whai whakaaro hoki mō tōna whakamahinga.
He aha te PEVA, ā, he aha tōna hiranga?
Ko te PEVA (polyethylene vinyl acetate) he pūhui hangai e whakamahia ana i roto i te hanga o ngā hua maha, tae atu ki ngā putea. He maha ngā āhuatanga e ātaahua ai te whakamahi: te ngāwari, te ātete ki te wai me te kaha. Kāore i rite ki te PVC, kāore he haukini i roto i te PEVA, ā, he pai ake mō te hauora me te taiao. Nā tēnei, kei te piki haere te rongonui o ngā putea PEVA. Heoi, kei te tuwhera tonu te pātai mō tōna pānga ki te taiao.
Ko tētahi o ngā āhuatanga nui ko te korenga o ngā tāpiringa paitini i roto i te rauemi. E kiia ana he iti ake te kino o te PEVA ki te tangata me te taiao i te nuinga o ngā kirihou. He mea nui kia poto ake te wā e pakaru ai te rauemi PEVA me te kore e tukuna he matū paitini – nā tēnei ka pai ake te taiao hei whakakapi mō ngā putea kirihou.
Ngā Painga o te Whakamahi i te Kai PEVA
I roto i ngā painga matua o te whakamahi i ngā putea PEVA, ka taea e tātou te whakanui i tōna whakamahinga anō me tōna ātete ki ngā āhuatanga o waho. Mā te putea kai PEVA me te reti ka taea e koe te penapena kai me te haumaru nā tōna piripono, te ārai i te pirau me te whakaiti i te nui o ngā para kai. He mea tino nui tēnei hei whakaiti i te nui o ngā para o te whare, he pānga nui tēnei ki te taiao.
He pai ngā putea PEVA mō te penapena i ngā kai anake, tae atu ki ētahi atu taonga. Nā te kaha me te ngāwari o te whakamahi, ka taea te whakamahi i ngā wā maha, ā, ka whakaiti i te whakamahinga o ngā takai whakakorekore. Nā te ngāwari o te tiaki me te horoi, ka māmā ake, ka watea hoki te whakamahinga mō ngā kaihoko.
Ngā āhuatanga taiao o te whakaputa me te whakakorenga
He iti ake ngā tukunga o te tukanga hanga o ngā putea PEVA i te hanga o ngā hua kirihou rite. Nā te iti o te matū me te iti o ngā utu pūngao i puta ai tēnei. Heoi, ko te tukanga hangarua o ngā putea PEVA tonu ka raru pea nā te kore o ngā kaupapa me ngā hangarau motuhake mō te hangarua.
I te nuinga o te wā, ka mutu aua pēke ki ngā whenua ururua, ka pirau, ahakoa he tere ake i te kirihou noa. Mā te tautoko me te whakawhanake i ngā hanganga mō te hangarua ka āwhina i te whakaiti i te taumahatanga taiao. Ko te whakauru i tētahi kaupapa mō te kohikohi me te hangarua i ngā pēke PEVA ki roto i ngā kaupapa a te kāwanatanga he taahiraa nui pea ki tēnei huarahi.
Te kawenga pāpori me te whakapau kaha
Ko te whakamahi āta i ngā putea PEVA ka whai wāhi pea ki tētahi rautaki whānui hei whakaiti i te pānga ki te taiao. Ka taea e ngā kaihoko te āwhina ki te tiaki i te taiao mā te whakaiti i ngā para kore-pirau me te whiriwhiri i ngā huarahi pai mō te taiao.Te putea kai PEVA me te raka retitētahi o aua huarahi kē atu.
Mā te whakapiki i te mōhiotanga ki ngā kino o ngā kirihou whakamahi-kotahi, me te whakakapi i aua mea ki ngā putea PEVA, ka tino rerekē ngā huarahi e whakamahia ana. Hei wāhanga o ēnei kaupapa, me whakahaere ngā huihuinga mātauranga me ngā kaupapa e whakamōhio ana i te iwi ki ngā āheinga o ngā kōwhiringa e tika ana mō te taiao.
Ngā tūmanakohanga me ngā wero mō te heke mai
Ko te whanaketanga o ngā hangarau hangarua PEVA me te whakapai ake i te wātea o ngā ratonga e pā ana he mahi nui ki te whakapiki i te pumau o tēnei umanga. Me arotahi ngā mahi ki tēnei wāhanga ki te waihanga i ngā pūnaha hangarua pai ake hei whakaiti i te tapuwae taiao.
He mea nui te ako me te whakatinana i ngā hangarau rerekē hei hanga rauemi e pai ake ana mō te taiao, tae atu ki ngā kōwhiringa ka taea te whakawairakau. Mō te wā roa, ka whakaitihia te whakawhirinaki ki ngā pūmua hangai, ā, ka neke atu ki te whakamahinga rauemi pumau ake.
Kei te tipu haere te hiahia ki ngā putea PEVA, ā, nā reira kua waiho hei pūtake mō te rangahau me te auahatanga i roto i te mara o tā rātou whakamahinga. Ka taea e ngā rōpū ngaio me ngā umanga te whai wāhi nui ki te tautoko me te whakawhanake i tēnei ia āhua pai ki te taiao.
Whakamutunga
He taahiraa nui ngā putea PEVA ki te whakamahi i ngā mea e aro nui ana ki te taiao. Mā te whakakotahi i ngā āhuatanga pēnei i te whakamahinga anō, te haumaru me te pakari, ka taea e rātou te whakakapi i ngā momo kirihou maha e whakamahia ana.He putea kai PEVA me te retika taea te whakamahi hei taputapu hei whakaiti i te nui o ngā para me te whakaiti i te pānga kino ki te taiao. Heoi anō, me whakapau kaha tonu ki te whakawhanake i ngā hangarau hangarua me te tukatuka, me te whakapiki ake i te taumata kawenga a ngā kaihanga me ngā kaihoko.
