I te 16 ki te 18 o Noema, 2020, i tū te Huihuinga ā-Ao me te Whakaaturanga 38 o te Komiti ā-Ao mō te Ako i te Bauxite, te Alumina me te Konumohe (ICSOBA) i runga ipurangi. E rau ngā māngai o te umanga konumohe mai i ngā whenua me ngā rohe neke atu i te 20 o te ao, pērā i te Hononga o Amerika, Rūhia, Brazil, te United Arab Emirates me Haina, i tae atu ki te hui.

Ko SHPHE anake te kaiwhakarato taputapu whakawhiti wera e whai wāhi ana i Haina, e tohu ana i te taumata rangahau me te whanaketanga teitei rawa atu o ngā taputapu whakawhiti wera i roto i te umanga alumina. I whakaū katoa te Komiti Hangarau ICSOBA me te whakanui nui i te tūhuratanga kaha me te rangahau hohonu a SHPHE i roto i te umanga alumina, ā, i tūtohu kia hanga e Tākuta Ren Libo o SHPHE te taitara "te mahi a te whakawhiti wera pereti awa whānui mō te whakatōnga Bayer" i te hui i te 17 o Noema. E whakaatu auaha ana tēnei pūrongo i te ariā wai me te thermodynamics o te tioata pakitara whakawhiti wera, e whakaatu ana i ngā taipitopito i te wheako mahi whai kiko o te whakawhiti wera pereti awa whānui mō te rere wai-totoka e rua-wāhanga i roto i te raupapa wehenga whakamatao whakakotahitanga o SHPHE, ā, e whakarāpopoto ana i te tūāpapa ratonga atamai ipurangi ahumahi o SHPHE.

Mō te whakawhiti wera pereti whānui-awa mō te rere wai-totoka-rua-wāhanga, ka taea e te tūāpapa ratonga atamai ipurangi ahumahi o SHPHE te whakarato i te rauropi mahi tauanga-tūturu me ngā tohutohu a te tohunga mō te whakahaere me te tiaki i te whakawhiti wera. Ko tētahi o ana rauropi matua ko te ariā o te rere wai-totoka-maha-wāhanga matūriki matotoru i roto i te awaawa whaiti. I ngā tau tata nei, kua akohia e SHPHE ngā āhuatanga rere wai-totoka-rua-wāhanga me ngā āhuatanga pakū, kua whakapai ake i te ariā o te rere wai-totoka-rua-wāhanga matūriki matotoru i roto i te awaawa o te whakawhiti wera awaawa whānui, ā, kua pakaruhia te tikanga hoahoa tika o te whakawhiti wera pereti whakarewa nui mō te rere wai-totoka-rua-wāhanga matūriki matotoru. Kua whakaputaina ētahi hua rangahau ki roto i ngā puka SCI / EI o ngā ahumahi matua i te kāinga me tāwāhi.
