He perehi iti nō te polieitana, e whai wāhi ana i te hanga i ngā taonga porositana. Nō reira, he mea nui ēnei perehi iti, nā te mea kei te whakaheke i te hanga i ngā hua whakatuturu, e whai wānga ana ki te oranga o te ao. Tae atu ki te ako i polyethylene pe me te polypropylene pp i tēnei tuhinga, ā, he aha ngā take e mahi ai ki te whakanuia i tō tātou ao.
Kei te whai pūtēa polietīhena i te momo pūnana e kī nei ko te polietīhena. Ko tēnei momo pūnana, nui rawa atu te mārō me te rangatiratanga, ā, ka taea te whakamahi ki te hanga o ngā mea katoa e pāngia ana e mātau i roto i ō mātau oranga kotidien. Nō reira, kei te hanga ngā pūtēa iti nei i te whakawehenga i te polietīhena, ka whakapuakea hei poitoitō iho. I te whakatūpū, ka hapainga ngā poitoitō nei, ka pakiponoa, ka whakaritea hei tūtohi, kia taea te whakamahi e ngā kāwanatanga me ngā rōpū kē ki te hanga i a rātou ake hua.
Kei ngā pūtē polyethylene te whakatupu i ngā mea e tata nei ki a mātou, mai i ngā kōkiri ki ngā pūwai wai ki ngā kāpiti kai. Nui rawa atu te huringa o ēnei mahi, nā rātau te wehi kei te maha, engari ko tō rātau mana he nui noa. Ka taea rātau te whakahē kia kaua te wai e kitea ana, e hē mihi ana — hei tauira, i ngā wāhi kai. Ko ngā pūtē polyethylene ka whai take ki te maha o ngā momo rongoā, ka whai ake tonu rātau i te whiuwhiu hei whakamahi i waenga i ngā tūranga katoa — mai i ngā mea whare kia puta noa ki ngā whakamahi pakihi.
Mehemea ka whakamahi ngā pūtē polyethylene mo ngā whakamahi katoa, kotahi anō he mea, ko te whakapakoko kai. Ka whai take anō hoki ngā pūtē kia whakatupu ai ngā kāpiti 100% tika kai, ka taea te whakamahia hei tiwhikete i te higiene me te haumanu o tō kai. Kei ngā kāpiti kēnei te whakarite i te kai kia ora ake i te wā e hāngai ana. Ko tēnā he mea pai, nā tērā ka heke i te mīhini kai, ka whakaora i ngā whanau moni, ka whakawhanake i te taiao ki te kore tangata e whakamahia ana i ngā rauemi.
Ko ngā wāhi kai hoki, ka whakamahi te polietilini i ngā pūhanga hei hanga i ngā poaka plastik, pērā i ēnei kei roto i ngā pakihi kai. Ka taea e rātou te whakahoki, he mea nui ake, he whanaketanga ki te kawe i ngā mea nui, pērā i ngā kai hoko me ēnei otinga kē, ki te kore e mohiotia ana. Ko tēnei manaakitanga he mea nui noa iho mo ngā hokohoko e hiahia ana kia kawe mai ō rātou hokohoko ki te kāinga mā whiwhi ora.
He whai hua nō te polietilini pūhanga, engari me whakaaro tonu mātou ki tana āhuatanga ki te taiao hoki. Kāore ngā pūhanga i whakamutu i te tika, e kī nei, ka puta ki ngā awa, ngā roto, me ngā moana. Ki te kitea, ka mate i te wai, ka mate hoki i te ao tangata, ā, i ngā manu me ngā ika, me ngā whenua o rātou e noho ai.
Ka mutu, ko te whai take hoki i whakamana rawa atu i tēnā low density polyethylene . Wētahi mea e whai wāhi ana ki te hanga i tēnā mea, tēnā mea nō te hanga pūhanga, inā ka noho ngā piipu, ngā rīpori whakawehi, me ngā matāpuna whakamamae. Nō reira, he mea mohio nei ēnei mahi i te hanga pūhanga, nā te mea he nui ake te mana o ēnei hua hei whakatika i ngā huarahi katoa, he whanake tonu, he whiuwhiu, he whakatuturu, ā, he whiuwhiu hoki i ēnei rerekē.
