The textile laundries industries generate residues that are difficult to treat and dispose of, known as sludge, consisting of organic matter and other chemical elements called heavy metals. Seeking to contribute to the reduction of the environmental impact caused by the disposal of this waste in the environment, this work aimed to study an alternative for recycling the sludge generated in the treatment of effluents from textile laundry industries by incorporating clay into the mass for the manufacture of ceramic sealing blocks used in civil construction. With a sludge/clay ratio of 20%, 50 units of sealing blocks with six holes were produced, with dimensions of 190 mm in length, 90 mm in width and 140 mm in height, in addition to 50 units of control blocks, produced only with clay. The quantity of ceramic blocks was established based on the minimum necessary sampling required in the norms of the Brazilian Association of Technical Norms. It was found that it is possible to incorporate up to 15% of sludge in the manufacture of ceramic blocks, without losing their essential qualities. The results of the tests performed are within the limits established by the regulations. The use of textile laundry sludge can increase the efficiency of industries involved in the manufacture of ceramic blocks, promoting a reduction in the extraction of natural resources used, as well as providing the textile laundry industry with a sustainable destination for the polluting waste.
