Kubikwa ukuthi iNorwegian Hydro Company ishintshele kubuchwepheshe bokugcwalisa imisele ye-bauxite ukuze ithathe indawo yedamu lemisele langaphambilini, ngaleyo ndlela ithuthukise ukuphepha kanye nokuvikelwa kwemvelo kwezimayini.
Ngesikhathi sokuhlolwa kwalesi sixazululo esisha, i-Hydro itshale imali ecishe ibe yi-US$5.5 million ekulahleni kokugcina kwezindawo ezisele endaweni yezimayini futhi yathola imvume yokusebenza ekhishwe yisitifiketi se-Para State Secretariat for Environment and Sustainability (SEMAS).
UJohn Thuestad, iPhini likaMongameli oPhethe lebhizinisi le-bauxite ne-alumina le-Hydro, uthe: “I-Hydro ibilokhu izibophezele ekukhuthazeni intuthuko esimeme yemboni ye-aluminium, ngakho-ke senze imizamo yokusebenzisa lo mzamo wokugwema ukumbiwa kwe-bauxite. Ukusungulwa kwamachibi amasha ahlala njalo ngesikhathi sokumbiwa kubangela izingozi zemvelo.”
Isixazululo sikaHydro siwumzamo wakamuva wokulahla i-bauxite tailings embonini. Kusukela ngoJulayi 2019, iHydro ibilokhu ihlola lobu buchwepheshe emayini ye-bauxite yaseMinerao Paragominas enyakatho yesifundazwe sasePara. Kuyaqondakala ukuthi lolu hlelo aludingi ukwakhiwa okuqhubekayo kwamadamu amasha e-tailings ahlala njalo, noma ngisho nokwengeza izendlalelo esakhiweni sedamu le-tailings esikhona, ngoba uhlelo lusebenzisa indlela ebizwa ngokuthi “i-dry tailings backfilling”. , Okusho ukuthi, i-backfill inert dry tailings endaweni yemigodi.
Isigaba sokuhlola salesi sixazululo esisha se-Hydro senziwa ngaphansi kokuqapha nokulandelela isikhathi eside kwezinhlangano zemvelo, futhi silandela amazinga obuchwepheshe eKomidi Lezemvelo (i-Conama). Ukusetshenziswa kwalesi sixazululo esisha eBrazil kuyisinyathelo esibalulekile entuthukweni esimeme, ukuthuthukisa ukuphepha kokusebenza kanye nokunciphisa ukuthinteka kwe-Hydro kwezemvelo. Ukuhlolwa kwephrojekthi kwaqedwa ekupheleni kuka-2020, kanti i-Para State Secretariat for Environment and Sustainable Development (SEMAS) yavunyelwa ukusebenza ngoDisemba 30, 2020.
