He wāhanga nui ngā mekameka roera i roto i ngā momo mahi ahumahi me ngā mahi mīhini, tae atu ki ngā mahi motuka, te hanga me te ahuwhenua. Ka whakamahia ēnei hei tuku hiko me te kawe rauemi. Heoi, ka pā nui ngā rauemi e whakamahia ana i roto i ngā mekameka roera ki te taiao. He mea nui te mārama ki te pānga taiao o ngā rauemi mekameka roera ki te whakatau whai whakaaro mō te whakamahinga me te whakakorenga atu.
Ko ngā rauemi e whakamahia whānuitia ana mō ngā mekameka roera ko te rino, te kowiri tira, me te maitai waro. Mai i te tango rauemi mata ki te tukanga hanga me te whakakorenga whakamutunga, he pānga taiao tō ia rauemi.
Ko te rino te rauemi e whakamahia whānuitia ana i roto i ngā mekameka hurihuri, ā, ko te nuinga o te wā he mea hanga mai i te rino me te waro. Ko te tango i ēnei rauemi mata he nui te whakapaunga pūngao me te whakararuraru i te taiao. Ko te tukanga whakarewa rino hei hanga rino ka tukuna hoki te hauhā waro me ētahi atu hau kati kōtuhi ki te āhuarangi, ka whai wāhi atu ki te huringa āhuarangi. Hei tāpiri, ko te hanga rino he whakamahi i ngā momo matū me te whakaputa para ka poke i te wai me te oneone.
He rino koranu ātete-waikura te maitai kore waikura, kei roto ko te chromium, te nickel me ētahi atu huānga. Ahakoa he roa te ora o te maitai kore waikura, ka pā kino pea te tango me te tukatuka i ōna rauemi mata, inā koa ko te chromium me te nickel, ki te taiao. Ka taea e te keri me te whakamahine i ēnei konganuku te arahi ki te whakangaromanga o ngā nohoanga, te horo o te oneone me te parahanga wai. Hei tāpiri, me nui te whakauru pūngao ki te hanga maitai kore waikura, ka hua ake he tukunga waro me te whakaiti rauemi.
Ko te maitai waro tētahi atu rauemi noa e kitea ana i roto i ngā mekameka roera, ā, ko te nuinga he rino me te waro. He rite tonu ngā āwangawanga taiao ki te hanga maitai waro ki te maitai tuku iho, tae atu ki te keri i te rino me te waro, me te tukunga o ngā hau kati kōtuhi i te wā o te tukanga hanga. Hei tāpiri, ko te nui o te waro i roto i te maitai waro ka ngawari ki te waikura, ka arahi pea ki te pakaru wawe me te whakakapinga, ka pā kino atu ki te taiao.
I ngā tau tata nei, kua piki haere te hiahia ki te tūhura i ngā rauemi rerekē mō ngā mekameka roera hei whakapai ake i te mahi taiao. Ko tētahi o aua rauemi ko te kirihou, he kaha ki te whakaiti i te pānga taiao o ngā mekameka roera. Ka taea te hanga mekameka kirihou mai i ngā rauemi hangarua, ka whakaiti i te hiahia mō ngā rauemi hou, ka huri i ngā para mai i ngā whenua ururua. Hei tāpiri, he māmā ngā mekameka kirihou, he ātete ki te waikura, ā, he iti ake te kaha e hiahiatia ana hei hanga i ngā mekameka whakarewa.
Ko tētahi atu huarahi whai hua ko te whakamahinga o ngā rauemi koiora, pērā i ngā kirihou koiora, i roto i te hanga mekameka roera. Ka ahu mai ngā kirihou koiora i ngā rauemi whakahou pērā i te māngaro witi, te tō huka, te cellulose rānei, ā, he huarahi pumau ake ki ngā kirihou tuku iho. Ko te hanga kirihou koiora he iti ake te tapuwae waro, ā, he iti ake te pānga ki te taiao i ngā kirihou hinu.
Hei tāpiritanga, ko ngā whanaketanga o ngā rauemi hiato pēnei i ngā pūmua kua whakapakarihia ki te muka waro ka taea te whakapai ake i te mahi taiao o ngā mekameka roera. He mama ēnei rauemi, he pakari, ā, he nui te ōwehenga kaha-ki-taumaha, ka whakaiti i te whakapaunga pūngao i te wā e whakamahia ana, ā, ka whakaiti i te hiahia mō te whakakapinga pinepine.
Haunga te tūhura i ngā rauemi rerekē, ka pā anō hoki te hoahoa me te tiaki i tētahi mekameka roera ki tōna pānga ki te taiao. Mā te whakahinuhinu me te tiaki tika ka roa ake te ora o ngā mekameka roera, ka whakaiti i te auau whakakapinga me te tapuwae taiao e pā ana. Hei tāpiri, mā te whakawhanake i ngā hoahoa mekameka whai hua me te pakari ka āwhina i te tiaki rauemi me te whakaiti i te para.
Ina tae te mekameka roera ki te mutunga o tōna oranga whai hua, he mea nui ngā tikanga whakakore me te hangarua tika hei whakaiti i tōna pānga ki te taiao. Mā te hangarua i ngā mekameka whakarewa ka āwhina i te tiaki i ngā rauemi taiao me te whakaiti i te pūngao e hiahiatia ana hei hanga mekameka hou. Hei tāpiri, mā te hangarua i ngā kirihou me ngā mekameka koiora ka whai wāhi ki tētahi ōhanga porowhita, ka taea ai te whakamahi anō me te whakamahi anō i ngā rauemi, ā, ka whakaitihia te taumahatanga taiao whānui.
Hei whakarāpopototanga, he pānga nui tō ngā rauemi e whakamahia ana i roto i ngā mekameka roera ki te taiao mai i te tangohanga me te hanga tae noa ki te whakakorenga whakamutunga. Ahakoa kua roa ngā rauemi tuku iho pēnei i te maitai me te kowiri tira hei rauemi whiriwhiri mō te hanga mekameka roera, kei te piki haere te hiahia ki te tūhura i ngā rauemi rerekē hei whakapai ake i te mahi taiao. Mā te whakaaro ki te pānga taiao o ngā rauemi mekameka roera me te tango i ngā huarahi kē atu e pumau ana, ka taea e ngā ahumahi te whakaiti i ō rātou tapuwae taiao me te whai wāhi ki tētahi heke mai matomato.
