As a building material blocks and tiles are to this day, widely used and so there are several potteries and ceramics industries that manufacture these products. In Brazilian industries, when the blocks or tiles are not burned correctly, i.e. when not acquire a desired coloring or when they have small defects such as cracks or small flatness; they are usually discarded in nature, thus generating a considerable environmental liabilities. In this work we used such wastes to obtain a new ceramic product containing these residues. Through characterization of the clay and the waste, using physical and chemical testing, as well as the conformation of specimens with different percentages it was found that a percentage of 5 to 10% utilization of the waste obtains a new ceramic product. This new product will provide economic use of raw materials with the use of waste and consequently a reduction in aggression nature.
