Ko te rauropi he mea nui rawa atu e āhei ai mātau ki te hanga i ngā mea nui o tō tātou ao kotidien. Kei te kite koe i ōu taiao, me te whakaaro kia mea atu kē kua hanga mai i hea? Ināianei ka ako mātau i te PP, PE, me te HDPE - ko ngā tohu matua e toru o te rauropi. Kērē kē ēnei kupu, engari ko ēnei te mea pai rawa!
PP ( ) Ko tēnā he mīhini whakatupu nui rawa atu e āhei ana ki te whakamutu huarere hoki. PP (poriporipileni) PP: polipropilēne. Whakaarohia ngā wāhi mīhini e whai ake nei i a koe hei kawe moa nui (kaore ia e whekewheke). Kua whakamahia te PP mō ngā mea katoa, mai i ngā wāhi kai ki ngā pūtiki poaka ki ngā mea nui o aua mea e whai ake nei i a koe i roto i te kāhui kai. He mīhini toa, ka rongo tonu ai tō kai i ngā kino.
Kei muri nei, kei te PE, e hiahia ana ki te polieitene. Ki te tika i te PP, kei te malo me te kaweke te PE. Ko te mea matua e kitea ana kei roto i te nuinga o nga pouaka pākē i te marae kai, ko te PE! He momo kawekaweke tonu ia, kaore he papatea. Ka pai te PE mo nga poaka wai, ngaa pouaka pākē me ngaa kawekawe kai. Whakaaro atu he hoa kawekawe: ka taea e ia te kawekawe me te tiaki i nga mea.
Ko te HDPE (high-density polyethylene) te tuatoru o ngā motutōtara. Ko tēnei he motu whakapuakatanga nui hoki, e āhei ana ki te tahuri i ngā wāhi iti me ngā wāhi māuiui. Mēnā ka whakamahi i te HDPE mo ngā pīpu, ngā takoto nui, ā, ākona, mo ngā kete para. He mea māhea tēnei, e ora tonu ana i runga i te mate. Ka taea e koe te whakaatu i te HDPE hei pīpu e tuku wai ana, engari e kore e mohio, rānei ko te kete para e taea ana te noho i te rā, i te ua.
He motu e whakaae nei i a tātou ki te hanga i te maha o ngā mea e pāngia ana e tātou i ia rangi. Nō reira, mai i ngā tākaro e whakanui nei ki ngā pūhā e inu ai tātou, kei tērā ngā motu tino whakapuakitanga e whakawheawehea nei i a tātou. He mea nui ake hoki rātou i te hanga i ngā mea e hiahiatia ana, e haumaru ana, me te pai hoki. Nā ngā whakangao pērā i Yuezheng ka mahi ki te hanga i ēnei motu, ka whakarerekētia hei tapa mahi e hiahiatia nei e tātou.
Kīhai ngā pēpeke i whakaaro kē ki te whiwhi i tētahi maha o ngā rauropi, ka whakaaro he aha te hātepe e hiahiatia ana hei whakamahinga. Kei te hiahia ia ki tētahi nui? Kei te hiahia ia ki tētahi e taea ana te tahutahu? Me pēhea te rauropi e āhei ana ki te mahi i ngā mea whakataka, me ngā mea whakamā? He nuinga nō ngā rauropi, ināianei he whakamahi tūmatawhānui.
He nui ngā rauropi e pai ana ki te kawe kai, ko ētahi pai ki te hanga kete, ko ētahi pai ki ngā mea e hiahiatia ana kia mana. Whakaarohia ko te pouaka taputeranga, kei reira ngā momo tapu hoki, engari ka mutu te mahi i te tautoko i te takiuru pai, ināianei he takiuru e hangaia nei ki te wā e hiahiatia ai.
