Ko ngā pounamu me ngā ipu e hangaia ana mā te whakamahi i te Post-Consumer Resin (PCR) he ia e tipu haere ana i roto i te umanga tākai – ā, ko ngā ipu PET kei mua i taua ia. Ko te PET (Polyethylene terephthalate rānei), e hangaia ana mai i ngā wahie pūmua, tētahi o ngā kirihou tino noa o te ao – ā, ko tētahi o ngā kirihou ngāwari ki te hangarua. Nā tēnei ka waiho te hanga Polyethylene terephthalate (PET) me te ihirangi PCR hei kaupapa matua mā ngā Rangatira Waitohu. Ka taea te hanga i ēnei pounamu me te ihirangi PCR i waenga i te 10 ōrau me te 100 ōrau – ahakoa me hiahia ngā Rangatira Waitohu ki te whakaiti i te māramatanga me te ataahua o te tae mō ngā ōrau ihirangi piki haere.
● He aha te PCR?
Ko ngā mea hangarua o muri i te kaihoko, e mōhiotia whānuitia ana ko te PCR, he mea hanga mai i ngā taonga e hangarua ana e ngā kaihoko i ia rā, pērā i te konumohe, ngā pouaka kātene, te pepa, me ngā pounamu kirihou. Ko te tikanga ka kohia ēnei rauemi e ngā kaupapa hangarua ā-rohe, ka tukuna ki ngā whare hangarua kia wehewehea hei pēra, i runga i te rauemi. Kātahi ka hokona ngā pēra, ka rewahia (ka hurihia rānei) hei pire iti, ka hangaia hei taonga hou. Kātahi ka taea te whakamahi i te rauemi kirihou PCR hou mō ngā momo hua kua oti, tae atu ki te takai.
● Ngā Painga o te PCR
Ko te whakamahinga o ngā rauemi PCR he urupare a te kamupene takai ki te oranga tonutanga o te taiao me tōna kawenga mō te tiaki taiao. Mā te whakamahinga o ngā rauemi PCR ka taea te whakaiti i te kohikohinga o ngā para kirihou taketake, te whakatutuki i te hangarua tuarua, me te penapena rauemi. Ka rite hoki te takai PCR ki tekoungao ngā takai ngāwari noa. Ka taea e te kiriata PCR te tuku i te taumata tiaki, te mahi ārai, me te kaha rite tonu ki te kiriata kirihou noa.
● Te Pānga o te Ōwehenga PCR ki te Tākai
Ka pā nui te tāpiritanga o ngā momo ihirangi o ngā rauemi PCR ki te tae me te māramatanga o te takai. Ka kitea i te pikitia i raro nei, i te pikinga ake o te kukū PCR, ka pōuri haere te tae. Ā, i ētahi wā, mā te tāpiri nui rawa o te PCR ka pā ki ngā āhuatanga matū o te takai. Nō reira, i muri i te tāpiri i tētahi ōwehenga o te PCR, me mahi he whakamātautau hototahi hei kite mēnā ka pāngia te takai e te tauhohenga matū ki ngā ihirangi.
