Muaj kev tshaj tawm tias Norwegian Hydro Company tau hloov mus rau cov thev naus laus zis qhuav ntawm bauxite tailings los hloov lub pas dej tailings yav dhau los, yog li txhim kho kev nyab xeeb thiab kev tiv thaiv ib puag ncig ntawm kev khawb av.
Thaum lub sijhawm sim ntawm qhov kev daws teeb meem tshiab no, Hydro tau nqis peev kwv yees li US $ 5.5 lab hauv kev pov tseg zaum kawg ntawm cov tailings hauv thaj chaw khawb av thiab tau txais daim ntawv tso cai ua haujlwm los ntawm Para State Secretariat for Environment and Sustainability (SEMAS) daim ntawv pov thawj.
John Thuestad, Tus Lwm Thawj Coj ntawm Hydro lub lag luam bauxite thiab alumina, hais tias: "Hydro yeej ib txwm cog lus los txhawb kev txhim kho kev lag luam txhuas kom ruaj khov, yog li peb tau siv zog los siv qhov kev sim no kom tsis txhob muaj kev khawb bauxite. Kev tsim cov pas dej tshiab tas mus li thaum lub sijhawm khawb av ua rau muaj kev phom sij rau ib puag ncig."
Hydro txoj kev daws teeb meem yog qhov kev sim tshiab tshaj plaws los pov tseg cov bauxite tailings hauv kev lag luam. Txij li Lub Xya Hli 2019, Hydro tau sim cov thev naus laus zis no ntawm Minerao Paragominas bauxite mine hauv sab qaum teb Para xeev. Nws nkag siab tias qhov kev pab cuam tsis tas yuav tsum tau tsim kho cov pas dej tshiab tas mus li, lossis txawm tias ntxiv cov khaubncaws sab nraud povtseg rau cov qauv pas dej uas twb muaj lawm, vim tias qhov kev pab cuam siv txoj kev hu ua "qhuav tailings backfilling". , Ntawd yog, backfill inert qhuav tailings hauv thaj chaw mined.
Lub sijhawm sim ntawm qhov kev daws teeb meem tshiab no ntawm Hydro yog ua tiav raws li kev saib xyuas thiab taug qab ntev ntawm cov koom haum ib puag ncig, thiab ua raws li cov qauv kev tshaj lij ntawm Pawg Neeg Saib Xyuas Ib puag ncig (Conama). Kev siv cov kev daws teeb meem tshiab no hauv Brazil yog ib kauj ruam tseem ceeb rau kev txhim kho kom ruaj khov, txhim kho kev nyab xeeb ua haujlwm thiab txo Hydro qhov chaw ib puag ncig. Kev sim project tau ua tiav thaum kawg ntawm xyoo 2020, thiab Para State Secretariat for Environment and Sustainable Development (SEMAS) tau pom zoo rau kev ua haujlwm thaum Lub Kaum Ob Hlis 30, 2020.
