Using factorial experimental design, it was observed that a residue addition did not promotes the increase on the real porosity and apparent porosity of the sintered ceramics. By means of the results obtained it was observed that at both sintered temperatures 1100 ° C and 1200 ° C the test bodies inerted the heavy metals. The metals incorporated in the ceramic material were not leached according to the ABNT NBR 10005: 2004 standard. The incorporation of waste into the ceramic mass is economically feasible and environmental favorable, because it reduces the cost of the waste of ink to be discarded as well as it avoids its disposal in the environment.
