<b>Abstract.</b> Industrial laundries generate sludge from the settling of the solids in suspension, which are presents in the liquid effluents. The characterization of this sludge demonstrated the presence of metals such as: Mg, Al, Ca, Cr, Co, Cu, Mn, Zn. Disposal of this sludge is an environmental problem to the laundries due to the presence of these metals and chemicals products used in the dying and washing processes as well as those chemicals used in the final treatment of effluents. In order to minimize the environmental problems caused by inadequate sludge disposition, it was studied the sludge incorporation in to mortar using the solidification/stabilization technique based on cement. Mortar proof bodies containing 10% and 20% of sludge had the resistance to compression tested and after were tested for metals leaching. The results of resistance to compression showed a decrease in the resistance with an increase of sludge due mainly the presence organic matter in the sludge, which was superior to 50%. The leaching tests showed the capacity of the mortar in retaining the metal pollutants satisfactorilyThe abstract text is to be included here.
