Munguva yekuedza mhinduro itsva iyi, Hydro yakaisa mari inosvika US$5.5 miriyoni mukubvisa tsvina munzvimbo yemugodhi uye yakawana mvumo yekushanda yakapihwa neSecretariat yePara State Secretariat for Environment and Sustainability (SEMAS).

Mhinduro yeHydro ndiyo nzira yekupedzisira yekubvisa tsvina yebauxite muindasitiri. Kubva muna Chikunguru 2019, Hydro yave ichiedza tekinoroji iyi pamugodhi weMinerao Paragominas bauxite kuchamhembe kwePara. Zvinonzwisisika kuti chirongwa ichi hachidi kuvakwa kwemadhamu matsva ekugara kwenguva refu, kana kutowedzera zvidimbu kune chimiro chedhamu remarara chiripo, nekuti chirongwa ichi chinoshandisa nzira inonzi "dry tailings backfilling". , Kureva kuti, backfill inert dry tailings munzvimbo yakacherwa.
Chikamu chekuyedza mushonga mutsva weHydro uyu chinoitwa pasi pekutariswa kwenguva refu uye kuteverwa kwemasangano ezvakatipoteredza, uye chinotevedzera mitemo yehunyanzvi yeDare reZvivako (Conama). Kushandiswa kwemushonga mutsva uyu muBrazil idanho rakakosha rekusimudzira nharaunda, kuvandudza kuchengetedzeka kwekushanda uye kuderedza kukanganiswa kweHydro nenharaunda. Kuyedzwa kwepurojekiti kwakapedzwa pakupera kwa2020, uye Para State Secretariat for Environment and Sustainable Development (SEMAS) yakatenderwa kushanda musi wa30 Zvita, 2020.
