Tauira Pātai Kōrero: Ngā Tauira o ngā Kirihou
Ko te kirihou tētahi o ngā rauemi e whakamahia whānuitia ana i roto i te oranga o ia rā. He maha ngā whakamahinga e whakamahia ana, mai i ngā takai kai ki ngā wāhanga waka. I roto i tēnei tuhinga, ka tirohia e mātou ngā tauira raruraru e matapaki ana i ngā momo kirihou, ō rātou āhuatanga, me te whakamahinga whānuitia i roto i te oranga o ia rā.
He aha te Kirihou?
He rauemi te kirihou i hangaia mai i ngā mekameka pūmua roa i hangaia mai i ngā momo monomer. Ka taea te tango mai i ēnei monomer mai i ngā pūtake taiao, i ngā pūtake hangai rānei. He maha ngā wā ka whakamahia te kirihou nā te mea he māmā, he pakari, he ngāwari hoki ōna āhuatanga. Heoi, kāore i te rite te hanga o ngā kirihou katoa; he maha ngā momo me ngā āhuatanga me ngā whakamahinga rerekē.
Ngā momo kirihou
I mua i tā tātou haere tonu, kia mōhio tātou ki ētahi o ngā momo kirihou e kitea whānuitia ana:
1. Polyethylene (PE)
– Kōrero: Ko te polyethylene tētahi o ngā momo kirihou e tino whānuitia ana te hanga puta noa i te ao. E rua ngā momo matua o te polyethylene: te Polyethylene Kiato-Teitei (HDPE) me te Polyethylene Kiato-Iti (LDPE).
- Tauira raruraru:
– He aha ngā rerekētanga matua i waenga i te HDPE me te LDPE e pā ana ki te hanganga matū me ngā whakamahinga?
2. Polypropylene (PP)
– Kōrero: He kirihou te polypropylene he ātete ki te wera, ā, he maha ngā wā ka whakamahia mō ngā momo hua tae atu ki ngā ipu kai me ngā wāhanga motuka.
- Tauira raruraru:
– He aha i whakamahia pinepine ai te polypropylene i roto i te umanga kai?
3. Polyvinyl Chloride (PVC)
– Kōrero: He momo kirihou maha ngā whakamahinga o te PVC, e whakamahia ana i roto i te hanganga mō ngā paipa, ngā anga matapihi, me ngā papa.
- Tauira raruraru:
– Whakahuatia ngā whakamahinga o te PVC i roto i te oranga o ia rā, ehara i te mea hei paipa.
4. Porotireini (PS)
– Kōrero: He kirihou te polystyrene e whakamahia whānuitia ana i roto i ngā takai kai me ngā taputapu tēpu whakakorekore.
- Tauira raruraru:
– He aha te mea e pai ai te whakamahi i te polystyrene hei rauemi takai kai?
5. Polyethylene Terephthalate (PET)
– Kōrero: He momo kirihou te PET e whakamahia whānuitia ana i roto i ngā pounamu inu me ngā takai kai.
- Tauira raruraru:
– He aha i whakamahia ai te PET mō ngā pounamu inu?
Kōrero mō ngā Tauira Pātai
Kia matapakihia e tātou ētahi o ngā pātai i runga ake nei kia hohonu ake:
Pātai 1: Ngā Rerekētanga Matua i waenga i te HDPE me te LDPE
Whakautu:
Ko te rerekētanga matua i waenga i te HDPE me te LDPE kei roto i ō rāua hanganga matū:
– HDPE: He hanganga ngota ngota he rārangi ake, he iti ake te peka. Nā tēnei ka kaha ake, ka pakari ake, ka ātete ake hoki te HDPE ki te wera. Ka whakamahia te HDPE i roto i te hanga taonga pēnei i ngā pounamu wai, ngā paipa, me ngā taonga takaro.
– LDPE: He hanganga manga nui. Nā tēnei ka ngāwari ake te LDPE, ā, ka ātete hoki ki te pēhanga iti. He maha ngā wā ka whakamahia te LDPE i roto i te hanga putea kirihou, takai kirihou, me ngā ipu kai.
Pātai 2: Te Polypropylene i roto i te Ahumahi Kai
Whakautu:
He maha ngā take e whakamahia ai te polypropylene (PP) i roto i te umanga kai:
– Ātete Wera: Ka taea e te PP te tu atu i ngā pāmahana teitei i te wā o te tukanga whakahoromata.
– Kāore e Tauhohe ki te Kai: Kāore te PP e tauhohe ki te maha o ngā matū, ā, kāore hoki e kino te kounga o te kai.
– Māmā: Mā tēnei ka māmā te kawe me te tukatuka.
Pātai 3: Te Whakamahinga o ngā Paipa PVC o Waho
Whakautu:
Haunga te whakamahinga hei paipa, ka whakamahia anō hoki te PVC mō:
– Ngā anga matapihi me ngā tatau: Nā te mea he ātete pai ki te huarere me te whakamarumaru wera.
– Papa winīri: Nā te mea he ngāwari ki te horoi, he pakari hoki.
– Ngā taonga tākaro a ngā tamariki: Nā te ngāwari me te pakari.
Pātai 4: Te Whaihua o te Polystyrene hei Rauemi Tākai Kai
Whakautu:
He pai te whakamahi i te polystyrene hei rauemi takai kai nā ēnei āhuatanga e whai ake nei:
– Ngāwari: Ka māmā ake te tuku me te rokiroki.
– Pūmautanga Wera: Ka taea te ātete i ngā pāmahana kai, ahakoa makariri, ahakoa wera.
– Te Āhua Matū Korekore: Kāore e tauhohe ki ngā kai kua takaihia, nō reira he haumaru te whakamahi.
Pātai 5: Te Whakamahinga o te PET mō ngā Pounamu Inu
Whakautu:
He maha ngā whakamahinga o te PET mō ngā pounamu inu nā te mea:
– Kaha: He kirihou kaha, he kirihou mama hoki te PET.
– Kore-paitini: Haumaru hei whakamahi mō ngā takai kai me ngā inu.
– Mārama: He mārama ngā pounamu PET kia kite mārama ai ngā kaihoko i ngā mea kei roto i te hua.
Te Pānga o te Kirihou ki te Taiao
Ahakoa he maha ngā painga o te kirihou i roto i te oranga o ia rā, he pānga kino anō hoki tōna whakamahinga ki te taiao. Ka pāngia te oneone, te wai, me te moana e te kirihou kāore i te whakahaeretia tika. Kua kitea anō hoki ngā kirihou moroiti i roto i ngā momo rauropi, e whakaatu ana i ngā wero o te whakahaere i ngā para kirihou.
Ngā Mahi Whakaiti me te Whakahaere Kirihou
Hei whakaiti i ngā pānga kino o te kirihou, he maha ngā mahi ka taea te mahi:
– Te hangarua: Whakapai ake i ngā mahi hangarua kia taea ai te whakamahi anō i ngā kirihou.
– Ngā Rauemi Rerekē: Te whakawhanake i ngā rauemi rerekē e pai ake ana mō te taiao.
– Te Whakaiti i te Whakamahinga o ngā Kirihou Kotahi-Whakamahinga: Whakaitihia te whakamahinga o ngā kirihou kotahi-whakamahinga mā te huri ki ngā rauemi ka taea te whakamahi anō.
Whakamutunga
He rauemi tino whai hua te kirihou i roto i ngā momo mahi maha nā te mea he māmā, he ngāwari, he pakari hoki ōna āhuatanga. Heoi, he rerekē ngā momo kirihou me ōna āhuatanga me ōna whakamahinga. Mā te mārama ki ēnei rerekētanga me te mahi i ngā mahi hei whakaiti i te pānga ki te taiao, ka taea e tātou te whakamahi i te kirihou me te whakaaro nui ake.
Kua kapi i tēnei tuhinga ētahi tauira pātai me ngā kōrero mō ngā momo kirihou. Ko te tumanako ka āwhina tēnei ki te whakanui ake i te mōhiotanga me te māramatanga ki te hiranga o te mārama ki ngā āhuatanga o ngā momo kirihou me te whakamahi pai me te whai kawenga.
