Inadequate discard of industrial solid waste is a risk to human health and to the environment. For softening environmental damage caused by deposition on soil of an ink residue, from washing of printers used in carton box packages, it’s intended to incorporate this residue into soil-cement bricks. However, to explore the waste’s potentialities it’s fundamental to assess the risks that this form of use of residue can cause. For such, in this work the chemical analysis of the waste was performed in order to know the main chemical compounds and leaching and solubilization characteristics. The chemical composition test showed traces of some heavy metals, although the residue-generating company uses ink labeled as heavy metals free. Some of the elements analyzed in leaching and solubilization showed a concentration above the limit allowed by The Brazilian Codes. Therefore, it’s suggested the residue has a limited use to avoid contamination of ground water.
