The "Phosphate Sludge Waste" is generated by various types of industries whose manufacturing process entails phosphatizing treatment during coating on metallic surfaces. The present study presents an option for recycling Phosphate Sludge Waste as an alternative raw material in the manufacturing of ceramic blocks (bricks), in order to lower the costs and environmental damages arising from the disposal of such residue, and yet sparing environmental impacts due to the extraction of natural resources. The results demonstrated in this work has shown that the best formulation mix was the one that used 10% of phosphate waste in substitution to clay, recommended its use as class 10 ceramic blocks.
