Te whakaputa hauwai me te hau māori He iti te utu me te pānga tauine. Ko te rangahau me te whakawhanake i ngā hangarau tukanga hou matatau ake mō te hanga hauwai mai i te hau māori he taurangi nui hei whakaoti rapanga o te pūtake hauwai iti te utu. Hei pūngao ahumahi kounga teitei, ma hoki, he rauemi mata rautaki nui te hau māori i roto i te tukanga whakawhanaketanga pūngao o Haina. I taua wā anō, koia anō hoki te rauemi mata taketake o te maha o ngā hua matū tuarua.
Hei hua matū tuarua, he whānui te whakamahinga o te hauwai i roto i ngā ahumahi rongoā, matū pai, hikohiko me te hiko. Ina koa, ko te hauwai, hei wahie pai mō ngā pūtau wahie, ka whānui ngā tirohanga mākete i roto i te mara o te kawe waka me te whakaputa hiko a meake nei, ā, ka nohoia e ia tētahi tūranga nui ake i roto i te hanganga pūngao a meake nei. Kua tino pakari ngā tikanga whakaputa hauwai tuku iho, pērā i te hurihanga mamaoa hauwai māmā, te hikohiko wai, te pakaru methanol, te whakapūnga waro me te wehewehenga haukini. Heoi, kei reira ētahi raruraru, pērā i te utu nui, te tere whakaputa iti, te iti o te whai huatanga o te mahi, kotahi te teitei me te rua te iti. I roto i te tukanga whakaputa hinu me te hau i te Marae Hinu o Liaohe, kei reira ngā rauemi hauwai pērā i te hau maroke me te naphtha. Ka taea e te whakaputa hauwai mā tēnei tikanga te whakanui ake i te whakamahinga o ngā rauemi. Hei tāpiri, ko te wāhanga matua o te hau maori e pā ana ko te methane, ka taea te huri hei hauwai mā te mamaoa hauwai, me te parakore whakaputa teitei me te whai huatanga whakaputa teitei.
Ko ngā tukanga tukatuka matua o te hau māori ko te whakatōtō hau me te korehau, te pakaru whakakorikori, te whakahou whakakorikori me te whakaputa kakara. I taua wā anō, tae atu ki te whakamahi, te kohikohi me te purenga o te hau māori, ka tauhohe ngā alkane me te mamaoa i roto i te hau māori i raro i tētahi pēhanga, pāmahana teitei me te whakakorikori.
I muri i te whakawhiti wera i roto i te poihau utu, ka tomo te hau kua hurihia ki te oumu nekehanga hei huri i te Co ki te H2 me te CO2. Kātahi, i muri i te whakawhiti wera, te whakatōtō me te wehenga wai mamaoa, ka tukuna te hau i roto i te pourewa mimiti e toru ngā mea mimiti motuhake mā te whakahaere kaupapa, ā, ka pēhia te N2co CH4 CO2 ka mimitihia mā te pēhanga me te mimiti i te pēhanga hurihuri (PSA) hei tango i te hauwai hua, hei whakaiti i te pēhanga me te tātari hei tuku i ngā poke me te hanga anō i te mea mimiti.
