Alunorte received on June 21 a license to operate the solid residue deposit area (DRS2). The license will allow the operation of the deposit, after the installation phase and all commissioning tests, properly licensed and followed by environmental agencies.
DRS2 is a long-term solution of the alumina refinery operation and fundamental for continuity of aluminum chain in Pará, contributing to Hydro's strategic agenda. The operation of DRS2 means a huge technological, sustainability, and safety advance for the aluminium industry in Pará.
DRS2 has generated, since the commissioning and testing step, more than 300 news jobs in the region of Barcarena. This is combined with the technology of the press filter, the most modern available in the world to manage bauxite residue. The press filter technology results in residue with about 78% solid content, and allows for stacking for compaction, there reducing storage area.
Total investment in the press filter installations and the building of DRS2 is BRL 1 billion. As a result of this modernization program, Alunorte became a pioneer in the application in large scale of two technologies.
