Recycling the bottom ash from MSWI (Municipal solid waste incinerators) ash is required to reduce the secondary pollution. We characterized the bottom ash and investigated the possibility of application for subsidiary ceramic raw materials. Major components of bottom ash are analyzed as CaO, Al2O3, SiO2, P2O5, MgO, Fe2O3, which are the same components of the earth’s crust. This similarity of components implied that bottom ash could be recycled as ceramic products through systematic treatment. Considering the plasticity and water absorption results, the ceramics, which are the mixture with 74 wt % bottom ash and 26 wt% Pink Kaolin, showed 1.39% water absorption after sintering 1150oC for 1h. This result indicated the possibility of recycling of bottom ash for subsidiary ceramic raw materials.
