Results and Objectives
From 2017 to 2024, more than 1.8 million cubic meters of water (approximately 720 Olympic-sized swimming pools) and 27,000 tons of caustic soda were reused, avoiding the purchase of supplies and making more water available to society. With the start of operation of the filters, the liquids removed from the waste continue to be reused in the process.
The filter presses became operational at the end of the first half of 2024 and are undergoing operational adjustments to reach their maximum capacities. This is expected to eliminate the need for wet disposal of the residue, allowing for complete water recirculation and reuse of caustic soda. Dry disposal increases the dam's safety and avoids impacting new areas for the disposal of these residues. Furthermore, studies are underway for reuse in other industries, such as in civil construction for the manufacture of pozzolanic cement.
Of 2017 to 2024, more than 1.8 billion liters of water were reused. to dry the dam. Annually, the volume of 70 million liters will be reused..
With the elimination of the liquid fraction, 70,000 tons of material will no longer be sent to the dam annually. With the dry residue, CBA is also advancing in industrial-scale studies for the reuse of the material in the manufacture of pozzolanic cement, with the potential to utilize 100% of the volume generated, which totals approximately 500,000 tons per year.
By 2030, CBA aims to eliminate the disposal of waste in dams.
