Ko te umanga hanga pepa tētahi o ngā pūtake parahanga ahumahi matua e ono o te ao. Ko te nuinga o ngā wai parahanga hanga pepa e ahu mai ana i te wai whakapūkara (waipiro pango), te wai takawaenga, me te wai mā o te mīhini pepa. Ka taea e te wai parahanga mai i ngā whare hanga pepa te whakapoke nui i ngā puna wai e karapoti ana, ā, ka nui hoki te kino ki te taiao. Nā tēnei āhuatanga i aro atu ai ngā kaitiaki taiao puta noa i te ao.
I te mea e piki haere ana te mōhiotanga ki ngā kawenga taiao, he mea tino nui te aro atu ki te parahanga taiao e puta mai ana i ngā wai para hanga pepa. Ka taea e te mīhini tātari whitiki te whai wāhi nui ki ngā mahi whakakore paru, ki te whakaora paru rānei i roto i te umanga hanga pepa.
He mira pepa rongonui i Danyang, Jiangsu
I te Porowini o Jiangsu, he mira pepa rongonui e kaha ana ki te whakahaere i te wai para tae atu ki te 24000m3 i ia rā, nā te mea e whakamahi ana i te tukanga maimoatanga koiora anaerobic (UASB). He nui ngā muka, ngā matūriki iri, me ngā matū pirau kore i roto i te paru. Nō reira, he mea tika te mahi whakamaroke wai a te mīhini whakamaroke. Whai muri i ngā haerenga maha ki te papaanga, i hokona e tēnei wheketere ētahi mīhini tātari whitiki raupapa HTB-2000 e toru mai i tā mātou kamupene i te marama o Poutū-te-rangi, 2008.
Kua tino makona ā mātou kiritaki ki te tere o te wai, te kaha tukatuka, te horopeta, me ētahi atu āhuatanga, mai i te whakamahinga o ngā taputapu. I roto i ēnei, ka eke te nui o te wai totoka ki te neke atu i te 28% i muri i te whakamātotoru me te tango wai, he pai ake tēnei i te paerewa i whakatakotoria e ā mātou kiritaki. Nō reira, ka tino heke te utu mō te whakakorenga i te paru i muri i te maroke.
Kaupapa OKI Rōpū Sinar Mas i Indonesia
I hokona e te wheketere e waru ngā mīhini whakamaroke pūwero hurihuri HTE-2500L (momo taumaha), i tukuna i te marama o Pēpuere, 2016. E 6400 mita pūtoru o te paru e tukatukahia ana e te mīhini, ā, ko te nui o te wai o te paru e tomo mai ana he 98%.
Mā te mahi tahi me ngā kamupene hanga pepa nunui me ngā kamupene hanga pepa rahi-waenga i Haina me tāwāhi, ka taea e HaiBar te tito i ngā otinga whakamaroke paru pepa-mira tino pūtaiao me ā mātou kiritaki i runga i ngā āhuatanga o te paru i te papaanga. Nau mai haere mai ki te awheawhe hanga o tā mātou kamupene, me te tirotiro hoki i ngā wāhi whakamaroke paru o ā mātou kiritaki o nāianei i roto i te umanga hanga pepa.
