Votorantim Metais´s Alumínio plant received an honorable mention for its “Reuse of Water from the Bauxite Waste Tailings Dam” project at the ninth presentation of the FIESP Conservation and Reuse of Water Prize.
The project aims to reuse the water contained in the dam through a filter-press to increase the concentration of solid particles produced by the refinery from 50% to 70%. This modification allows the recovery of caustic soda and increases the working life of the dam by at least 20 years.
“This is an incentive that will encourage us to continue developing new technologies and aluminum production processes with the focus on recovering water resources,” said Eduardo Escobar, the plant consultant who is in charge of the project.
The FIESP Prize involved 21 companies, divided into two categories: medium/large and micro/small. The award granted by FIESP, the São Paulo State Federation of Industries, aims to recognize good practices in reducing the consumption and waste of water, thereby creating environmental, economic and social benefits and making the sector more competitive.
