Nws tau tshaj tawm tias Lub Tuam Txhab Norwegian Hydro tau hloov mus rau cov tshuab ziab khaub ncaws qhuav ntawm bauxite tailings los hloov cov tailings dam yav dhau los, yog li txhim kho kev nyab xeeb thiab kev tiv thaiv ib puag ncig ntawm cov mining.
Thaum lub sijhawm kuaj cov tshuaj tshiab no, Hydro tau nqis peev kwv yees li US $ 5.5 lab hauv kev pov tseg zaum kawg ntawm cov tailings hauv cheeb tsam mining 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's bauxite thiab alumina lag luam, tau hais tias: "Hydro yeej ib txwm tau cog lus los txhawb txoj kev loj hlob ntawm kev lag luam txhuas, yog li peb tau siv zog los siv qhov kev sim no kom tsis txhob bauxite mining.Kev tsim cov tailings tshiab tas mus li lub pas dej thaum lub sijhawm mining ua rau muaj kev phom sij ib puag ncig. "
Hydro cov tshuaj yog qhov kev sim tshiab tshaj plaws los pov tseg cov bauxite tailings hauv kev lag luam.Txij li thaum Lub Xya Hli 2019, Hydro tau sim cov thev naus laus zis no ntawm Minerao Paragominas bauxite mine nyob rau sab qaum teb Para xeev.Nws tau nkag siab tias qhov kev zov me nyuam tsis xav tau kev tsim kho txuas ntxiv ntawm cov tailings dams tshiab, lossis tseem ntxiv cov txheej txheem rau cov tailings dams uas twb muaj lawm, vim tias qhov kev zov me nyuam siv txoj kev hu ua "qhuav tailings backfilling"., Uas yog, backfill inert qhuav tailings nyob rau hauv lub mined cheeb tsam.
Kev sim theem ntawm qhov kev daws teeb meem tshiab ntawm Hydro yog ua raws li kev soj ntsuam mus sij hawm ntev thiab taug qab ntawm cov koom haum ib puag ncig, thiab ua raws li cov txheej txheem ntawm Pawg Neeg Saib Xyuas Ib puag ncig (Conama).Daim ntawv thov ntawm qhov kev daws teeb meem tshiab no hauv Brazil yog ib kauj ruam tseem ceeb rau kev txhim kho kom ruaj khov, txhim kho kev ua haujlwm nyab xeeb thiab txo qis Hydro ib puag ncig hneev taw.Kev ntsuas qhov project tau ua tiav thaum kawg ntawm 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.
