Kubikwa ukuthi i-Norwegian Hydro Company ishintshele kubuchwepheshe bokugcwalisa i-backfill eyomile ye-bauxite tailings ukuze ithathe indawo yedamu langaphambili le-tailings, ngaleyo ndlela yenza ngcono ukuphepha nokuvikelwa kwemvelo kwezimayini.
Ngesikhathi sokuhlolwa kwalesi sixazululo esisha, i-Hydro yatshala imali elinganiselwa ezigidini ezi-US$5.5 ekuchithweni kokugcina kwezinsalela endaweni yezimayini futhi yathola imvume yokusebenza ekhishwe isitifiketi se-Para State Secretariat for Environment and Sustainability (SEMAS).
UJohn Thuestad, iPhini Likamongameli Omkhulu webhizinisi le-bauxite ne-alumina le-Hydro, uthe: “I-Hydro ibilokhu izibophezele ekukhuthazeni intuthuko esimeme yemboni ye-aluminium, ngakho senze imizamo yokuqalisa lo mzamo wokugwema ukumbiwa kwe-bauxite.Ukusungulwa kwamachibi amasha ahlala unomphela ngesikhathi sokumbiwa kudala izingozi zemvelo.”
Isixazululo se-Hydro siwumzamo wakamuva wokulahla i-bauxite tailings embonini.Kusukela ngoJulayi 2019, i-Hydro ibihlola lobu buchwepheshe emayini ye-bauxite yaseMinerao Paragominas enyakatho yesifunda sasePara.Kuyaqondakala ukuthi lolu hlelo aludingi ukwakhiwa okuqhubekayo kwamadamu amasha ezinsalela, noma ngisho nokwengeza izendlalelo esakhiweni esikhona sedamu le-tailings, ngoba lolu hlelo lusebenzisa indlela ebizwa ngokuthi “i-dry tailings backfilling”., Okusho ukuthi, i-backfill inert tailings eyomile endaweni yezimayini.
Isigaba sokuhlola salesi sixazululo esisha se-Hydro senziwa ngaphansi kokuqapha nokulandelela isikhathi eside kwama-ejensi wezemvelo, futhi silandela izindinganiso zobuchwepheshe zeKomidi Lezemvelo (Conama).Ukusetshenziswa kwalesi sixazululo esisha eBrazil kuyisinyathelo esibalulekile esiholela ekuthuthukisweni okusimeme, ukuthuthukisa ukuphepha kokusebenza kanye nokunciphisa indawo ezungezile ye-Hydro.Ukuhlolwa kwephrojekthi kwaqedwa ekupheleni kuka-2020, futhi i-Para State Secretariat for Environment and Sustainable Development (SEMAS) yagunyazwa ukuthi isebenze ngo-December 30, 2020.
