The catalytic cracking process is performed under heat, pressure and solid-acid catalysts, with zeolites being the most commonly catalysts. As soon as the virgin catalyst is put to use in the unit in operation, its activity begins to decline, mainly due to coking and metals contamination. This waste is treated as hazardous waste, and its disposition in a controlled landfill is the least noble alternative in the order of priority for solid waste management. Therefore, the objective of this work is to provide an alternative for the use of the catalyst waste as raw material for the red ceramic industry. For that, laboratory specimens were developed by extrusion, by replacing 0 to 30% of sand by the residue, and sintered at 850 ║C. The highly favorable results demonstrated that the use of this waste has the ability to reduce the density of the ceramic body and increase its mechanical strength.
