Kuxelwe ukuba iNkampani ye-Homegian Hydro iguqulwe kwitekhnoloji yomthendeleko owomileyo we-bauxite ukutshintsha idama laseBauxite ukuze itshintshe idama laseBasite, ngaloo ndlela ukuphuculwa kwezemigodi.
Ngexesha lokuvavanywa kwesisombululo esitsha, i-HYDRO ityale imali malunga ne-US $ 5.5 yezigidi ekuphelisweni kwemigodi kwaye yafumana imvume yokusebenza ekhutshwe yi-Paratime yendalo kunye nokuzinza (semas).
UJohn Thuestad, ungumongameli we-Hydro's Bauxite kunye neShishini le-Aluminina, wathi: "I-Hydro isoloko uzibophelele ekukhuthazeni uphuhliso oluzinzileyo lweshishini le-aluminium, ngenxa yoko senze iinzame zokuphumeza ukumba kwe-bauvite yemigodi. Ukusekwa kwezinto ezintsha ezisisigxina zomsila ngexesha lokumbiwa zibangela iingozi zendalo. "
Isisombululo sikaHydro yinzame yakutsha nje yokulahla imisila ye-bauxite kwishishini. Ukusukela ngoJulayi ngo-2019, i-HYDRO isetyenzisile le teknoloji kwi-Myrao Parigominas ye-Bauxite kwi-parati kamantla. Kuyaqondwa ukuba le nkqubo ayifuni ukwakhiwa kwamadama amatsha esisigxina, okanye ukongeza iingqimba kulwakhiwo lwedama elikhoyo, kuba le nkqubo isebenzisa indlela ebizwa ngokuba yi "imisila eyomileyo". , Oko kukuthi, i-backfill ye-inter tares eyomileyo kwindawo yemigodi.
Isigaba sokuvavanya kwesisombululo esitsha se-hydro senziwa phantsi kweliso kwixesha elide kunye nokulandelela iiarhente zendalo, kwaye kulandela imigangatho yezobugcisa yeKomiti yezeNdalo (i-coma). Ukusetyenziswa kwesi sisombululo sitsha eBrazil linyathelo elibalulekileyo kuphuhliso oluzinzileyo, ukuphucula ukhuseleko lokusebenza kunye nokunciphisa i-hydro yendawo yokusingqongileyo. Ukuvavanywa kweprojekthi kwagqitywa ukuphela kuka-2020, kwaye oonobhala bakarhulumente bendalo esingqongileyo kunye nophuhliso oluzinzileyo (i-seomas) bavunywa ukuba basebenze nge-30 kaDisemba 2020.
