Air pollution control residues (APCr) from municipal solid waste incineration (MSWI) are considered hazardous waste due to the high content of heavy metals and leachable salts and, therefore, must be treated and disposed of in special landfills. The significant production of APCr and the high content of \nvaluable components (Zn, Pb, Cu, and salts) make this material a potential anthropogenic source for resource recovery. Therefore, it is necessary to find effective methods for the removal of hazardous properties of APCr with simultaneous recovery/utilization of valuable components that are present in the \nmaterial. The paper summarizes possibilities for resource recovery and utilization of APCr from MSWI plants in the Czech Republic by hydrometallurgical methods. The results show that the recovery of salts is possible by water washing, valuable metals remaining in the insoluble form in stabilized APCr can be recovered by acid leaching, the remaining mineral matrix can be utilized in the construction industry.
