Mai i te tau 2018 ki te tau 2022, i piki ake te kaha o ngā waeine tunu whakaroa i Haina, kātahi ka heke iho, ā, i piki ake te kaha o ngā waeine tunu whakaroa i Haina i ia tau i mua i te tau 2019. I te mutunga o te tau 2022, ko te kaha o ngā waeine tunu whakaroa i Haina tata ki te 149.15 miriona tana, ā, kua whakawhitia ētahi waeine, ā, kua whakamahia. I te 6 o Noema, i angitu te whāngai tuatahi o te 2 miriona tana/tau o te waeine tunu whakaroa o te Kaupapa Whakauru Matū Shenghong (Shenghong Refining and Chemical) ā, i hua mai ngā hua whai tohu. I haere tonu te whānui o te kaha o te waeine tunu whakaroa i te Rawhiti o Haina.
I piki ake te whakamahinga whānui o te kōka hinu ā-rohe mai i te tau 2018 ki te tau 2022, ā, i noho tonu te whakamahinga katoa o te kōka hinu ā-rohe ki runga ake i te 40 miriona tāne mai i te tau 2021 ki te tau 2022. I te tau 2021, i tino piki ake te tono o te hekenga, ā, i piki ake te tere tipu o te whakamahinga. Heoi, i te tau 2022, i tūpato ētahi o ngā umanga hekenga ki te hoko nā te pānga o te mate urutā, ā, i heke paku te tere tipu o te whakamahinga o te kōka hinu ki te 0.7%.
I roto i te mara o te anode kua tunua-mua, kua piki haere te auau i roto i ngā tau e rima kua pahure ake nei. I tētahi taha, kua piki ake te tono ā-rohe, ā, i tētahi atu taha, kua piki haere hoki te auau o te kaweake o te anode kua tunua-mua. I roto i te mara o te irahiko karāhe, kei te mahana tonu te whakahoutanga taha tuku mai i te tau 2018 ki te 2019, ā, he pai te tono mō te irahiko karāhe. Heoi, i te ngoikore o te mākete maitai, ka ngaro te painga o te hanga maitai oumu pewa hiko, ka tino heke te hiahia mō te irahiko karāhe. I roto i te mara o te kaihoko whakapūkara, kua pumau te kai o te kōka hinu i ngā tau tata nei, engari i te tau 2022, ka tino piki ake te kai o te kōka hinu nā te pikinga o te kaihoko whakapūkara hei hua taha o te whakapūkara. Ko te hiahia mō te kōka hinu i roto i te mara wahie e whakawhirinaki ana ki te rerekētanga utu i waenga i te waro me te hinu, nō reira ka tino rerekē. I te tau 2022, ka noho teitei tonu te utu o te kōka hinu, ā, ka piki ake te painga utu o te waro, nō reira ka heke te kai o te kōka hinu. He pai te mākete o te konganuku silicon me te silicon carbide i ngā tau e rua kua pahure ake nei, ā, kua piki ake te whakamahinga whānui, engari i te tau 2022, he ngoikore ake i tērā tau, ā, kua paku heke te whakamahinga o te petroleum coke. Ko te mara o ngā rauemi anode, e tautokona ana e te kaupapa here ā-motu, kua piki haere i ia tau i ia tau i ngā tau tata nei. Mō te kaweake i te waro kua whakapūkaratia, me te pikinga ake o te tono ā-rohe me te nui o te hua ā-rohe, kua heke te pakihi kaweake o te waro kua whakapūkaratia.
Matapae mākete ā muri ake nei:
Mai i te tau 2023, tera pea ka piki ake te hiahia mō te umanga kōka hinu ā-rohe. Mā te pikinga, te whakakorenga rānei o ētahi o ngā kaha o te whare hanga hinu, i roto i ngā tau e rima e whai ake nei, ka eke te kaha whakaputa ā-tau o te tau 2024 ki tōna taumata teitei, kātahi ka heke ki tētahi āhua pumau, ā, e matapaetia ana ka eke te kaha whakaputa ā-tau o te tau 2027 ki te 149.6 miriona tana ia tau. I taua wā anō, me te tere o te whānui o te kaha whakaputa o ngā rauemi anode me ētahi atu umanga, kua eke te hiahia ki tētahi taumata kāore i kitea i mua. E matapaetia ana ka mau tonu te hiahia ā-rohe mō te umanga kōka hinu i te pikinga ā-tau o te 41 miriona tana i roto i ngā tau e rima e whai ake nei.
Mō te mākete mutunga tono, he pai te hokohoko whānui, kei te piki haere tonu te whakamahinga o ngā rauemi anode me te mara graphitization, he kaha te tono mō te maitai o te mākete konumohe waro, ka uru mai te wāhanga coke kawemai ki te mākete waro hei tāpiri i te tuku, ā, kei te whakaatu tonu te mākete coke hinu i tētahi āhuatanga kēmu tuku-tono.
