Mīhini te mīhini! Ka whakamanahia e tēnei i te maha o ngā mea e pāngia ana e mātou i ia rangi. He mīhini ētahi, he mīhini rereke, pērā i te pūruku; kaore ētahi, he pūmau noa, pērā i te papa. Ka ako tātou i te PE me te PP — e ai ki tēnā he momo mīhini.
Ko PE te ingoa mō Polyethylene. He mea e āhei ana ki te whakarerekē, ki te whakataki, ā, ka taea e ia te whakawhitinga me te whakapakaru ki te kawe i tana āhua anō hoki. Ko PE ko tētahi kete mīhini, ka taea e ia te whakapakaru hei poaka, ā, ka hoki mai ki tana āhua! Kei roto i ngā mea maha e pā ana ki tō whare. Ka whakamahi te PE ki te hanga i ngā kākahu wai, ā, i ētahi tāonga tamariki me ngā kete. Ko te mahi pai o te PE he whakamahia hei kawe i te haumaru me te kiriwhara, kāore i te āhei ki te kawe i te wai rānei.
PP e whai ana i te Polypropylene. Ko ia he rauropi pātata, kaha, e kore e mōhio ki te taumaro me te PE. Ko te PP pērā i tētahi mana whetū o ngā rauropi e āhei ana ki te hīkoi i ngā mahi nui! Ka whakamahia te MP hei hanga i ngā wāhi o ngā motokā, ngā rautaki oranga, me ēnei ka hiahia kia noho kaha. Ko tēnā he mea kē ki te PP, kei utu pai ai ki te huringa o te wera engari kāore i te PE. Ki te hiahia koe ki tētahi mea e kore e whatiwhati, e kore e takiri i tana rite ki te uru whenua, ko te PP ka mahi pai mōu.
Ko tēnei ka aro atu mātau ki ngā whakaaro mō tētahi mea e hiahia nei tātau ki te hanga, i te waekura i te PE rānei, te PP rānei. Kei te hiahia tātau ki tētahi mea e māku, e rokohanga? Rānei kei te hiahia tātau ki tētahi mea tuwhera, e āhei ana ki te tahuri i te wera? Nā ēnei pātai ka whakaae mai ki te whiriwhiringa i te rauropi tika mō tā tātau mahi.
“He mea nui tēnei te whiriwhiringa i te rauropi, pērā i te whiriwhiringa i te take pai hei whakatū i tētahi mahi. Ko te PE he materiana pai rawa mā te hanga i ētahi mea e hiahia ana kia taurombopū. Ko te PP te mea e kitea nei mā te hanga i ētahi mea e hiahia ana kia kaha me te taea te tahuri i te wera.
