In this study, the reduction efficiencies of leachate heavy metal levels were investigated by adding and CaO to the bottom ash to observe their effects on the heavy metals leachate reduction efficiency. The ratio of and CaO contents were varied by 10~40% (W/W) alongside different curing time of 7 and 28 days. The reduction efficiencies of leachate heavy metal levels were estimated to be 69.3% for Cu and 52.1% for Pb during the curing time of 7 days. For the curing time of 28 days, the efficiencies changed to 85.2 and 100% for Cu and Pb, respectively. It was thus confirmed that the high reduction efficiency could be obtained as the curing time increased.
