Zanenedwa kuti kampani ya Norwegian Hydro Company inasintha kugwiritsa ntchito ukadaulo wouma wa bauxite tailings kuti ilowe m'malo mwa damu la tailings lomwe linalipo kale, motero ikukweza chitetezo ndi chitetezo cha chilengedwe cha migodi.
Panthawi yoyesera njira yatsopanoyi, Hydro idayika ndalama zokwana US$5.5 miliyoni pakuchotsa zotsalira za nthaka m'dera la migodi ndipo idapeza chilolezo chogwirira ntchito choperekedwa ndi satifiketi ya Para State Secretariat for Environment and Sustainability (SEMAS).
John Thuestad, Wachiwiri kwa Purezidenti wa bizinesi ya Hydro ya bauxite ndi alumina, anati: “Hydro nthawi zonse yakhala ikudzipereka kulimbikitsa chitukuko chokhazikika cha mafakitale a aluminiyamu, kotero tayesetsa kukhazikitsa kuyesetsa kumeneku kuti tipewe migodi ya bauxite. Kukhazikitsidwa kwa maiwe atsopano okhazikika a m'mbuyo panthawi ya migodi kumabweretsa zoopsa zachilengedwe.”
Yankho la Hydro ndi njira yaposachedwa yochotsera zinyalala za bauxite mumakampani. Kuyambira mu Julayi 2019, Hydro yakhala ikuyesa ukadaulo uwu ku mgodi wa bauxite wa Minerao Paragominas kumpoto kwa boma la Para. Zikumveka kuti pulogalamuyi sikufuna kumanga madamu atsopano okhazikika, kapena kuwonjezera zigawo ku kapangidwe ka dziwe la zinyalala, chifukwa pulogalamuyi imagwiritsa ntchito njira yotchedwa "zouma zouma zosungira zinyalala". , Ndiko kuti, zouma zosungira zinyalala zosungira zinyalala zosungira zinyalala m'dera lomwe lakumbidwa migodi.
Gawo loyesa yankho latsopano la Hydro likuchitika motsogozedwa ndi mabungwe azachilengedwe kwa nthawi yayitali, ndipo limatsatira miyezo yaukadaulo ya Komiti Yachilengedwe (Conama). Kugwiritsa ntchito yankho latsopanoli ku Brazil ndi gawo lofunikira kwambiri pakukula kokhazikika, kukonza chitetezo cha ntchito ndikuchepetsa kuchuluka kwa Hydro pazachilengedwe. Kuyesa kwa polojekitiyi kunamalizidwa kumapeto kwa chaka cha 2020, ndipo Para State Secretariat for Environment and Sustainable Development (SEMAS) idavomerezedwa kuti igwire ntchito pa Disembala 30, 2020.
