METHOD FOR TREATING THE SLUDGE PRODUCED BY THE STONE CUTTING AND POLISHING PROCESS

摘要

Includes the thermal drying of said sludge, using for this purpose thermal energy from cogeneration equipment, and is characterised in that the steam from the drying of said sludge is condensed by also using the thermal energy from said cogeneration equipment. This enables valorization of the sludges from the stone cutting and polishing process, all this with very high energy efficiency and nil environmental impact.
