Abstract
With the ratio of municipal solid waste incineration residue to final disposal sites amounting to 77%, as of FY2008, it is crucial that resource recycling be systematically accelerated. For urban areas in particular, employment of ordinary Portland cement requiring dechlorination for large amounts of municipal solid incineration residue should be considered together with wide-area treatment that incorporates eco-cement requiring the use of up to 50% or more incineration residue for cement raw material. Meanwhile, the use of existing cement factories must also be considered for utilization of molten slag, metal recovery by extraction or physical sorting according to regional characteristics. Presentation of an optimal public system that will be able to contribute to integrated efforts for the environment, the economy, and society as a whole is required.
