Kuxelwe ukuba iNkampani yaseNorwegian Hydro yatshintshela kubuchwepheshe bokuzalisa umva owomileyo weentsalela zezimbiwa ze-bauxite endaweni yedama langaphambili leentsalela zezimbiwa, ngaloo ndlela iphucula ukhuseleko nokukhuselwa kokusingqongileyo kwemigodi.
Ngexesha lenqanaba lovavanyo lwesi sisombululo sitsha, iHydro ityale malunga ne-US $ 5.5 yezigidi ekuchitheni intsalela yeentsalela zezimbiwa kwindawo yemigodi kwaye yafumana imvume yokusebenza ekhutshwe sisatifikethi sePara State Secretariat for Environment and Sustainability (SEMAS).
UJohn Thuestad, uSekela Mongameli oLawulayo we-Hydro's bauxite kunye ne-alumina ishishini, uthe: "I-Hydro ibisoloko izibophelele ekukhuthazeni uphuhliso oluzinzileyo lweshishini le-aluminium, ngoko ke senze iinzame zokuphumeza le nzame yokuphepha imigodi ye-bauxite.Ukusekwa kwamachibi amatsha asisigxina ngexesha lokwembiwa kwemigodi kubangela ubungozi bemekobume.”
Isisombululo sikaHydro linyathelo lamva nje lokulahla iintsalela zebauxite kushishino.Ukusukela ngoJulayi ka-2019, iHydro ibivavanya le teknoloji kumgodi we-bauxite waseMinerao Paragominas kumantla ePara.Kuyaqondwa ukuba inkqubo ayifuni ukwakhiwa ngokuqhubekayo kwamadama amatsha eentsalela zezimbiwa ezisisigxina, okanye ukongeza iileya kulwakhiwo olukhoyo lwedama leentsalela zezimbiwa, kuba inkqubo isebenzisa indlela ebizwa ngokuba yi “dry tailings backfilling”., Oko kukuthi, i-backfill inert i-inert tailings eyomileyo kwindawo enemigodi.
Isigaba sokuvavanya kwesi sisombululo esitsha se-Hydro senziwa phantsi kokubeka iliso ixesha elide kunye nokulandelwa kwee-arhente zokusingqongileyo, kwaye ilandela imigangatho yobugcisa yeKomiti yeNdalo (eConama).Ukusetyenziswa kwesi sisombululo esitsha eBrazil linyathelo elibalulekileyo elibhekiselele kuphuhliso oluzinzileyo, ukuphucula ukhuseleko lokusebenza kunye nokunciphisa indawo yendalo ye-Hydro.Uvavanyo lweprojekthi lwagqitywa ekupheleni kuka-2020, kwaye i-Para State Secretariat for Environment and Sustainable Development (SEMAS) yamkelwa ukuba isebenze nge-30 kaDisemba 2020.
