I te haere tonu o te māramatanga ki te taiao, kua tīmatahia hoki e te umanga whakapaipai he huringa matomato i roto i ngā takai. Ehara i te mea ka pau noa te nui o ngā rauemi i roto i te tukanga whakaputa i ngā takai kirihou tuku iho, engari ka puta hoki he parahanga nui ki te taiao i te wā e tukatukahia ana i muri i te whakamahinga. Nō reira, kua noho ko te tūhura i ngā rauemi takai tauwhiro hei take nui i roto i te umanga whakapaipai.
Ngā kirihou kei runga i te hinu
Ko ngā kirihou hinu he momo kirihou i hangaia mai i ngā wahie pūmua pērā i te hinu. He pai tōna āhua kirihou me ōna āhuatanga miihini, nō reira he whānuitia te whakamahinga i roto i ngā momo mara. Ina koa, ko ngā momo kirihou hinu ēnei e whai ake nei:
Polyethylene (PE)
Polypropylene (PP)
Polyvinyl chloride (PVC)
Porotireini (PS)
Polycarbonate (PC)
Ko ngā kirihou hinu te mea nui rawa atu mō ngā takai whakapaipai nā te mea he mama, he roa, he iti hoki te utu. He kaha ake, he pakeke ake hoki ngā kirihou hinu, he pai ake te ātete ki ngā matū, ā, he pai ake te tukatuka i ngā kirihou tuku iho. Heoi, he nui ngā rauemi hinu e hiahiatia ana mō te hanga i tēnei rauemi, ā, ka nui ake te hekenga o ngā rauemi o te whenua. He nui ngā tukunga CO2 e puta ana i te wā o te tukanga hanga, ā, he pānga ki te taiao. I taua wā anō, he maha ngā wā ka maka noatia ngā takai kirihou i muri i te whakamahinga, ā, he uaua ki te pirau i muri i te urunga ki te taiao tūturu, ka kino rawa atu ki te oneone, ki ngā puna wai me ngā kararehe mohoao.
Ngā otinga hoahoa auaha mō te takai tauwhiro
Kirihou hangarua
He momo rauemi hou te kirihou hangarua i hangaia mai i ngā kirihou para mā roto i ngā tukanga pēnei i te kuru, te horoi, me te whakarewa. He rite ōna āhuatanga ki te kirihou tauhou, engari he iti ake ngā rauemi e whakamahia ana i roto i tana hanga. Mā te whakamahi i ngā kirihou hangarua hei rauemi takai whakapaipai, ehara i te mea ka taea anake te whakaiti i te whakawhirinaki ki ngā rauemi hinu, engari ka whakaiti hoki i ngā tukunga waro i te wā o te tukanga hanga.
Ngā kirihou koiora
Ko te kirihou koiora he rauemi kirihou i tukatukahia mai i ngā rauemi koiora (pēnei i te māngaro, te cellulose, me ētahi atu) mā te whakapūtanga koiora, te hanga me ētahi atu tukanga. He rite ōna āhuatanga ki ngā kirihou tuku iho, engari ka tere te pirau i roto i te taiao, ā, he pai hoki mō te taiao. Ko ngā rauemi mata o ngā kirihou koiora i ahu mai i te whānuitanga o ngā puna, tae atu ki te kakau witi, te para rakau, me ētahi atu, ā, he tino taea te whakahou.
Ngā rauemi takai rerekē
Haunga ngā kirihou hangarua me ngā kirihou koiora, he maha atu anō ngā rauemi tākai tauwhiro e wātea ana. Hei tauira, he māmā, he hangarua, he pirau hoki ngā painga o ngā rauemi tākai pepa, ā, he pai mō te whakamahi i roto i ngā tākai o roto o ngā mea whakapaipai. Ahakoa he taumaha ake ngā rauemi tākai karāhe, he tino pakari, he taea hoki te hangarua, ā, ka taea te whakamahi mō te tākai i ngā mea whakapaipai papai. Hei tāpiri, kei reira ētahi rauemi hiato koiora hou, ngā rauemi hiato whakarewa, me ētahi atu, e whakarato ana i ngā kōwhiringa maha atu mō ngā tākai whakapaipai.
Ka tutuki ngātahi ngā whanaketanga tauwhiro a ngā waitohu me ngā kaihoko
Ko te whakatutuki i te whanaketanga pumau o ngā takai whakapaipai me mahi tahi a ngā waitohu me ngā kaihoko. Mō ngā waitohu, me tūhuratia, me whakamahi hoki ngā rauemi me ngā hangarau takai pumau hei whakaiti i te pānga kino o ngā takai ki te taiao. I taua wā anō, me whakapakari anō hoki ngā waitohu i te mātauranga taiao mō ngā kaihoko, me te ārahi i ngā kaihoko ki te whakatū i ngā ariā kai matomato. Me aro nui ngā kaihoko ki ngā rauemi takai o ngā hua, me te whakanui i ngā hua he takai pumau. I te wā e whakamahia ana, me whakaiti te nui o ngā takai e whakamahia ana, ā, me whakarōpū tika, me whakakore hoki i ngā takai para.
I roto i te poto, ko te hurihanga matomato o ngā takai whakapaipai he huarahi nui mō te umanga whakapaipai ki te whakatutuki i te whanaketanga pumau. Mā te whakamahi i ngā rauemi me ngā hangarau takai pumau me te whakapakari i te mātauranga taiao, ka taea e ngā waitohu me ngā kaihoko te whai wāhi tahi ki te heke mai o te ao.
