Synthetic bottom ash of burnt urban waste containing heavy metal oxides, CdO, Cr2O3, Cu2O, PbO and ZnO, is reacted with polyvinyl chloride, PVC. The synthetic ash is prepared from chemical reagents of heavy metal oxides, Al2O3, CaO and SiO2. It is revealed that the heavy metal oxides except Cr2O3 are removed as metal chloride from the synthetic ash by PVC. It is considered that the heavy metals in bottom ash of burnt urban waste can be removed by use of end of life PVC.
