Ngā Whare Mana Koiora i roto i te Pūngao Rerekē
Kei te piki haere tonu te hiahia mō te pūngao o te ao i runga anō i te tipu o te taupori, te ahumahi, me te tere o te whanaketanga. I tētahi atu taha, ko te whakawhirinaki ki ngā wahie pūmua ka ara ake he maha ngā take, mai i te piki haere o ngā utu pūngao, te iti o ngā rahui, ki ngā pānga ki te taiao pērā i te parahanga o te hau me ngā tukunga hau kati kōtuhi. I roto i tēnei horopaki ka nui haere te hiranga o te pūngao rerekē. Ko tētahi puna pūngao rerekē e arohia ana ko te koiora. Ka whakamahia e ngā Whare Mana Pūngao Koiora (PLTBm) ngā rauemi rauropi hei wahie hei whakaputa hiko, e tuku ana i tētahi otinga pumau ake, me te whakatuwhera hoki i ngā whai wāhitanga mō te whakamahi i ngā para i iti iho te uara i mua.
Te Mārama ki te Koiora me te PLTBm
Ko te koiora he rauemi rauropi i ahu mai i ngā mea ora, i ō rātou toenga rānei, ahakoa mai i ngā tipu, i ngā kararehe, i ngā para ahuwhenua me ngā para ahumahi ngahere. Ko ngā tauira o te koiora ko te rakau, te puehu rakau, te kiri raihi, te kakau kānga, te bagasse, ngā paihere hinu nikau kau, te paru kararehe, tae atu ki ngā para rauropi o te whare. Ina tukatukahia te koiora mā roto i ētahi tukanga, ka taea te huri i te pūngao matū kei roto hei wera, hei hau, hei wahie wai rānei, ka taea te huri hei hiko.
He whare hiko koiora te tipu hiko e tukatuka ana i te koiora hei pūtake pūngao matua. He māmā noa iho, ka tahuna, ka tukatukahia rānei te koiora hei whakaputa wera, kātahi ka whakamahia hei whakaputa mamaoa, hei taraiwa i te tāpine , ā, ka hurihia e te tāpine te whakaputa hiko hei whakaputa hiko. Ahakoa he rite te kaupapa matua ki ngā tipu hiko wera e whakamahia ana te wahie pūmua, ko te wahie e whakamahia ana i ahu mai i ngā pūtake rauropi hou.
Me pēhea te whakaputa hiko mai i te koiora?
He maha ngā hangarau matua mō te whakaputa hiko e ahu mai ana i te koiora. He painga me he wero tō ia tikanga, i runga i te momo rauemi whāngai, te rahi o te tipu, me te whakamahinga e whakaarohia ana.
1. Te tahunga tika
Koinei te tikanga tino noa. Ka tahuna te koiora i roto i te kōhua hei whakaputa wera. Ka hurihia te wai e tēnei wera hei mamaoa pēhanga teitei, kātahi ka peia he tāpine. He pai tēnei tikanga mō te koiora totoka pērā i te rakau, te kiri raihi, te para ahuwhenua rānei.
2. Te whakapūngao
Ka whakamahanahia te koiora ki ngā pāmahana teitei me te iti o te hāora hei whakaputa i te hau hangai (syngas), arā, ko te hau waro hauota, te hauwai, me te methane. Kātahi ka tahuna ēnei syngas ki roto i te miihini tahu. hau, tāpine rānei hei whakaputa hiko. E kiia ana he pai ake te whakapūngao hau, ā, ka taea te whakaputa tukunga iti iho, engari me whai hangarau me whakahaere tukanga uaua ake.
3. Te Whakapūngao Piro
Ka whakamahanahia te papatipu koiora me te kore hāora hei whakaputa hinu koiora, hau, me te waro (biochar). Ka taea te whakamahi i te hinu koiora hei wahie hei whakaputa hiko, hei tukatuka atu rānei. Kei te whanake tonutia tēnei tikanga, ā, he maha ngā wā ka whakamahia i runga i te tauine nui.
4. Te Nakunaku Anaerobic mō te Biogas
Ka taea te whakapūkara i ngā para mākū pērā i te paru kararehe, i ngā para kai rānei e ngā moroiti i te korenga o te hāora hei whakaputa hau koiora (ko te methane te nuinga). Kātahi ka whakamahia te hau koiora hei whakakaha i ngā whakaputa hiko, i ngā tāpine rānei. He rongonui tēnei i ngā tauine iti ki te rahi, ā, he pai mō te pāmu kararehe, mō te maimoatanga wai para rānei.
Ngā Painga o ngā Pūwhakaputa Koiora
He maha ngā painga o te PLTBm e waiho ana hei wāhanga nui o te ranunga pūngao rerekē.
Tuatahi, te whakamahi i ngā para hei whakaputa pūngao. He maha ngā rāngai, pērā i te ahuwhenua, te ngahere, ngā māra, me te kararehe, e whakaputa ana i te nui o ngā para. Ki te kore e whakahaerea tika, ka taea e ēnei para te whakapoke i te wai me te hau, ka waiho rānei hei pūtake o ngā tukunga methane. Mā te tipu hiko wahie koiora (PLTBm), ka taea te huri i ngā para hei hiko e taea te whakamahi.
Tuarua, he pūtake pūngao whakahou , ā, he pumau tonu. Ki te whakatauritea ki te pūngao o te rā me te hau, e whakawhirinaki ana ki te rangi, ka taea te tuku i te koiora i runga i te auau tonu mena ka mau tonu te mekameka tuku rauemi mata. Nā tēnei ka waiho te koiora hei pūtake pūngao turanga pea, arā, te hiko ka taea te whakaputa tonu.
Tuatoru, te tautoko i te ōhanga ā-rohe. Ko te whakahaere i ngā tipu hiko koiora me whai wahie, e ahu mai ana i te rohe e karapoti ana. Ka hangaia he mahi, ka akiaki i te kohikohi me te tukatuka koiora, ā, ka whakapiki ake i te uara ōhanga o ngā para.
Tuawhā, kei a ia te kaha ki te whakaiti i ngā tukunga kupenga. I roto i te ariā, ko te waro e tukuna ana ina tahuna te koiora he rite ki te waro e mimitihia ana e ngā tipu i a rātou e tipu ana. Mena ka ahu mai te koiora i ngā puna e whakahaerehia ana i runga i te tauwhiro, ka taea e ngā tipu hiko wahie koiora te āwhina ki te whakaiti i ngā tukunga ki te whakataurite ki ngā tipu hiko wahie pūmua.
Ngā Wero me ngā Pānga o te Taiao
Ahakoa ngā painga maha o te PLTBm, he maha anō ngā wero me whakahaere kia tino pumau ai.
Ko te wātea me te whakahaere o ngā rauemi mata he herenga nui. He iti ake te kaha o te koiora i te waro, i te hinu rānei, ā, me nui ake ngā rahinga e hiahiatia ana. Mā te kohikohi, te whakamaroke, te penapena, me te kawe i te koiora ka piki ake ngā utu me ngā tukunga mena he tawhiti rawa.
Me aro atu hoki ki ngā mōrearea o te whakangaromanga ngahere me te hurihanga whenua. Mena ka akiakihia e ngā tipu hiko koiora te whakangaromanga ngahere, te whakatipu pūngao nui rānei i te utu mō te whenua ahuwhenua, ka taea e ngā pānga taiao te whakakore i ngā painga taiao e tumanakohia ana. Nō reira, ko ngā puna koiora pai ko ngā para, ko ngā hua rānei i whakatipuria ki runga i te whenua kua whakaitihia me ngā tikanga whakahaere mārama.
Ko ngā tukunga hau ā-rohe tētahi atu āwangawanga. Ka taea e te tahunga koiora te whakaputa i ngā matūriki iti (PM), ngā waikura hauota (NOx), me ētahi atu matū. He mea nui te whakamahi i ngā hangarau tahunga tika me te tāuta i ngā taputapu whakahaere tukunga pēnei i ngā tātari matūriki hei pupuri i te kounga o te hau.
He wero anō hoki te kounga o te wahie. Ka taea e te nui o te makuku te whakaiti i te pai o te tahunga. Nō reira, he maha ngā tukanga maimoatanga o mua pērā i te whakamaroke, te whakapūpū, te whakapūpū rānei e whakamahia ana hei hanga i te koiora kia ōrite ake, kia māmā ake ai te whakahaere.
Te Tūranga o te Koiora i roto i te Whakawhiti Pūngao
I roto i te mahere whakawhiti pūngao, ka taea e te koiora te tāpiri atu ki ētahi atu puna pūngao whakahou . Kei te piki haere te utu o te pūngao o te rā me te hau, engari he wā poto noa iho. Ka taea e te koiora te āwhina ki te whakakī i ngā āputa i roto i te tuku hiko ina heke te hanga o te rā, te hau rānei. Hei tāpiri, ka taea te whakamahi i te koiora ki ngā ariā whakaputanga tahi, ki ngā ariā wera me te mana whakakotahi rānei (CHP), e whakaputa ana i te hiko me te wera mō ngā ahumahi pēnei i ngā mira huka, ngā mira hinu nikau, ngā whare tukatuka rakau rānei. Mā te CHP, ka piki ake te whai huatanga o te pūngao nā te mea kāore te wera e moumouhia.
I roto i tētahi whenua ahuwhenua he nui ngā para ahuwhenua, he nui ngā whai wāhitanga kei roto i te koiora. Ka taea hoki te hono atu i te whanaketanga koiora ki te whakahaere para ā-tāone mā te wehewehe para rauropi me te whakaputa hau koiora. Mā te whakakotahitanga o ngā kaupapa here tika, te haumi hangarau, me te mātauranga tūmatanui ka whakapakari i te tūranga o te koiora hei puna pūngao rerekē.
Whakamutunga
He otinga pūngao rerekē ngā tipu hiko koiora, e āhei ana ki te huri i ngā rauemi rauropi me ngā para ki te hiko. Mā roto i ngā hangarau maha pērā i te tahunga tika, te whakapūngao hau, te whakapūngao hiko, me te whakaputa hau koiora, ka taea e te koiora te whai wāhi ki tētahi ranunga pūngao ma, pumau ake hoki. Kei roto i ōna painga ko te whakamahinga para, te pumau o te tuku, te tautoko ōhanga ā-rohe, me te kaha ki te whakaiti i ngā tukunga kupenga. Heoi, me whakamahere pakari me te tirotiro i ngā wero whakahaere, ngā mōrearea hurihanga whenua, ngā tukunga ā-rohe, me te kounga o te wahie. Mena ka whakahaerehia me ngā mātāpono pumau, ka taea e ngā tipu hiko koiora te noho hei pou nui i roto i te whakawhiti ki tētahi pūnaha pūngao e pai ake ana ki te taiao me te pakari ake i te heke mai.
