The work had as objective to aggregate the waste from the foundry industry, green sand, into ceramic material for the production of wall tiles. Characterization of the raw materials, clay and green sand through granulometric, fluorescence and X-ray diffraction analysis were performed in the work. To compare the green sand incorporation potential of in ceramic material, samples were made with red clay and with addition of 10% by mass of green sand. Subsequently water absorption, linear shrikange, apparent porosity, 4-point-flexural strength and environmental compatibility analysis (leaching and solubilization) were performed. These results compared to the standard allowed the validation and verified that green sand aggregation increases the samples resistance. In the environmental compatibility performed by leaching and solubilization test samples it was possible to observe that the material with green sand aggregation was classified as not hazardous. Based on the results, it was concluded that the green sand aggregation to the ceramic mass maintained the main characteristics when compared to the material without aggregation, and could be applied as a wall tiles.
