The high toxicity and the cumulative character of heavy metals have been of great concern worldwide, providing a significant increase in the number of studies that aim to develop technologies to remove these potentially noxious substances in the environment. Aiming to study the capacity of the building demolition residue (BDR) in removing heavy metals from leached of newly collected solid residue, analyses of metals adsorption were carried out. BDR was used in three granulation fractions (0.5 to 1; 2 to 4 and 4 to 7.5 mm) and leachate containing Cu, Cd, Pb and Zn in concentrations ranging from 0.046 to 150, from 0.146 to 200, from 0.135 to 200 and from 17.2 to 9000 mg L-1, respectively. The results allowed to conclude that BDR in the 2 - 4 mm and 4 - 7.5 mm granulation fractions presented the following sequence for the maximum retention capacity: Zn>Pb>Cu>Cd; but for BDR in the 0.5 - 1 mm granulation the sequence was Zn>Cu>Pb>Cd.
