Incineration processes are commonly employed for the treatment of municipal solid waste due to its advantages of mass and volume reduction. Two types of municipal solid waste incineration (MSWI) ashes which are bottom ash and fly ash are generated during the incineration process. Typically, the concentration of heavy metals, such as Cr and Pb, in fly ash are higher than in the corresponding bottom ash. Insolubilization treatment of heavy metals from MSWI fly ash was applied by preparing geopolymer mixed Akadama soil. Insolubilization effect and leaching behavior of heavy metals in the Akadama soil mixed MSWI fly ash geopolymer were evaluated by the Japanese leaching test No. 13 defined by the Ministry of the Environment and leaching test for fly ash in various countries. The geopolymer solidification method using Akadama soil is effective as an insolubilization treatment of heavy metals such as Cr and Pb.
