Air pollution control residues (APCr) are considered hazardous waste due to the high content of heavy metals and leachable salts. The production of APCr in the Czech Republic is ca. 20,000 tonnes per year and it is increasing. Therefore, it is necessary to find up-to-date methods for the removal of hazardous properties of APCr and, if possible, for the recovery/utilization of valuable components present in APCr. Water washing was considered a possible option for APCr stabilization and removal of soluble compounds. The paper summarizes the resource recovery potential of calcium-based APCr from MSWI plants in the Czech Republic. The results show that the recovery of salts from calcium-based APCr is possible by water washing, but the content of heavy metals did not meet legal limits for de-icing agents, therefore, multi-step stabilization and separation process is needed. At the same time, valuable metals remaining in the insoluble form are up-concentrated in stabilized APCr, which makes the material a suitable secondary source for acid extraction and recovery of Zn, Pb, and Cu.
