Nā te tere o te tipu o te hiahia mō te pūngao o te ao kua whakatakoto i te ara mō te whanaketanga o ngā rauemi taiao rerekē. Heoi, he mea nui tonu te waro i roto i te puna pūngao matua o te ao. Ko te waro te 29% o te tuku pūngao o te ao i te tau 2015, ā, e kiia ana i te tau 2035, ka 24% tonu te waro o te pūngao. Hei hua ā-ahumahi o ngā tipu hiko waro, ka noho teitei tonu te nui o te pungarehu rere waro mō te wā roa.Pungarehu rere waro kua waiho hei kaupapa matua mō te taiao nā te mea he uaua te hanganga me te koretake o te maimoatanga. I taua wā anō, he rauemi pea te pungarehu rere waro, me tere te whakamahi tika. I tēnei wā, he whānuitia ngā mara e whakamahia ana te pungarehu rere waro, engari he iti te tere whakamahinga uara teitei. Ko te kaupapa matua o te whakamahinga uara teitei ko te ako i ngā āhuatanga o te pungarehu rere waro. He mea tito te pungarehu rere waro i ngā matūriki porowhita totoka, koretake rānei, ngā matūriki waro kāore i tahuna, me ngā matūriki kohuke pērā i te mullite, te quartz, te hematite, me ētahi atu. He rerekētanga kei roto i ngā āhuatanga ā-tinana, te hanganga matū me te hanganga kohuke o te pungarehu rere waro i ngā rohe whakaputa rerekē. Kāore hoki i te ōrite te huarahi whakamahinga me te kaupapa. Ko te hanganga matatini o te pungarehu rere waro he arai nui ki te whakamahinga uara teitei. Heoi, ka taea te wehe i ngā wāhanga whai hua, pērā i ngā moroiti tuwhera, te waro kāore i tahuna, ngā rauemi aukume, me ētahi atu, mai i ngā wāhanga uaua mā ngā tikanga wehewehe tika. Ko te hanganga matū me te hanganga kohuke o te pungarehu rere he rauemi mata iti te utu mō ngā hua uara nui tāpiri pērā i ngā geopolymers, ngā karāhe-uku me ngā... Ngā zeolite. He nui te awe o te hanganga matū me te rahi o te matūriki taketake o te pungarehu rere waro ki te kaha o ngā geopolymer. Me whakatau ngā āhuatanga hangarau tino pai i runga i te whakaaro nui ki ngā āhuatanga taketake o te pungarehu rere waro i te wā e whakarite ana i ngā geopolymer. E ai ki te hanganga matū o te pungarehu rere waro, ko ngā uku-karaehe i hangaia mai i te pungarehu rere waro he rua ngā pūnaha matua: CaO-Al2O3-SiO2 me MgO-Al2O3-SiO2, engari he nui te whakapaunga pūngao o te tikanga whakarite. Me ako tonu, me whakatairanga hoki te tikanga sintering tika me te iti o te whakapaunga pūngao. He maha ngā whakamātautau tono o te zeolite i hangaia mai i te pungarehu rere waro, engari he iti noa ngā whakamātautau ahumahi e mahia ana. Kāore i te tino mārama te rangahau ariā mō te whakarite i ngā whakamātautau silica mesoporous me te silica aerosol, he uaua ki te whakahaere i ngā āhuatanga, ā, he roa tonu te ara i mua i te hanga ahumahi.
