Recycling and utilization of industrial and municipal waste in materials production

Dimension stone industry produces a great amount of effluents, about 200,000 ton/year per solid residue. Espírito Santo State has about 600 companies, and their average consume per industry is around are 10,000 l/ day of water. Those rejects are displaced in decant lagoons, and landfill. In this work was used material provided by marble & granite industry from Cachoeiro de Itapemirim, ES. Those residues were characterized by chemical and mineral composition, physical properties, sintering process, and point load test. The results provided from physical indices and sintering material were compared with the results of commercial granite named in Industry as "granito rosa bavena". Analysis allowed us to get a conclusion about the reject. These analyses showed that reject could be used as a source for ceramic material, with the possibility of choosing for a greater or lower resistance.
