A Study about Recycling from Municipal Solid Waste Incineration Bottom Ash

생활폐기물(生活廢棄物) 소각(燒却)바닥재의 재활용(再活用)을 위한 연구(硏究)

  • Published : 2008.02.27


The treatment of domestic municipal solid waste has inclined to incineration process instead of disposal in landfills. So, the amount of ash generated by incineration of municipal solid waste is gradually increased. The incineration ash divides into bottom ash and fly ash. The bottom ash which accounts for about 90% of the incineration ash consists of ceramics, glasses and metals. And it can be used as the recycling product by the stabilization process. For example, the bottom ash is used as secondary building material or for other similar purposes such as road sub-bases and noise barrier in USA, Europe and Japan. But, the stabilization-treatment technique of bottom ash sti11leaves much to be desired in Korea. Thus, the domestic study of recycling about bottom ash must be improved through investigation about the chemical property and technique of stabilization.
