I tēnei ao o nāianei, kua nui haere te hiranga o ngā mahi tauwhiro, ā, he pai hoki mō te taiao. Ko tētahi wāhanga e tino hira ana tēnei ko te umanga matū, e whakamahia whānuitia ana ngā whakarewa pēnei i te N-methyl-2-pyrrolidone (NMP). He whakarewa tino whai hua te NMP, engari ka pā kino pea tōna whakamahinga ki te taiao mēnā kāore e whakahaerea tika. Koinei te wāhi e whai wāhi mai ai te pūnaha whakaora NMP.

Ngā pūnaha whakaora NMPkua hangaia hei hopu me te whakaora i te NMP e whakamahia ana i roto i ngā momo tukanga ahumahi. Mā te pera, ehara i te mea ka whakaitihia e ēnei pūnaha te nui o te NMP e tukuna ana ki te taiao, engari ka āwhina hoki i ngā kamupene ki te penapena utu mā te whakamahi anō i ngā whakarewa. Nā tēnei painga rua ka waiho ngā pūnaha hangarua NMP hei wāhanga nui o te hanga matū pumau me te kawenga.

Ko tētahi o ngā painga matua o ngā pūnaha hangarua NMP ko te whakaiti i ngā para. Mā te hopu me te hangarua i te NMP, ka taea e ngā kamupene te whakaiti i te nui o te whakarewa e tukuna ana ki te taiao, ā, ka whakaitihia te tūponotanga o te poke me te parahanga. He mea nui tēnei i te mea he nui ngā tūponotanga kino ki te hauora me te taiao e pā ana ki te pānga o te NMP.

Hei tāpiritanga,Ngā pūnaha hangarua NMPwhai wāhi ki te tiaki rauemi. Mā te whakamahi anō i te NMP, ka taea e ngā kamupene te whakaiti i tō rātou whakawhirinaki ki ngā rauemi hou, ka whai hua ake te whakamahinga o ngā rauemi, ka whakaiti hoki i te hiahia mō ngā hua hou. Ehara i te mea he pai anake tēnei mō te taiao, engari ka āwhina anō hoki i ngā pakihi ki te whakaiti i ō rātou tapuwae taiao whānui.

Haunga ngā painga taiao, he painga ōhanga anō hoki ngā pūnaha hangarua NMP. Mā te whakamahi anō i te NMP, ka taea e ngā kamupene te whakaiti i te hiahia ki te hoko i ngā whakarewa hou, ā, ka whakaiti i ngā utu whakahaere. Ka taea e tēnei te hua ake he penapena utu nui i roto i te wā, ka waiho ngā pūnaha whakaora NMP hei haumitanga ōhanga pai mō ngā kaihanga matū.

Hei tāpiritanga, mā te whakatinana i tētahi pūnaha hangarua NMP ka taea te whakarei ake i te ingoa me te mana o tētahi kamupene i roto i te umanga. Mā te whakaatu i te whakapau kaha ki te oranga tonutanga taiao me ngā mahi hanga kawenga, ka taea e ngā kamupene te kukume mai i ngā kiritaki me ngā hoa mahi e aro ana ki te taiao, ā, i te mutunga ka whakapakari ake i tō rātou tūranga i roto i te mākete.

Hei whakamutunga,Ngā pūnaha hangarua NMPHe mea nui te mahi a ēnei pūnaha ki te whakatairanga i te oranga tonutanga o te taiao i roto i te umanga matū. Mā te hopu me te hangarua i te NMP, ka āwhina ēnei pūnaha ki te whakaiti i ngā para, ki te tiaki rauemi me te whakaiti i ngā utu whakahaere, me te whai wāhi atu ki tētahi taiao ma, hauora hoki. I te mea kei te piki haere tonu te hiahia mō ngā mahi oranga tonutanga, kāore e taea te whakanui rawa i te hiranga o ngā pūnaha hangarua NMP, ā, he wāhanga nui ēnei o te hanga matū kawenga.
