Abstract
In order to contribute to the survival of the general waste final disposal site, this study examined system optimization of the cement recycling of waste incineration main ash in metropolis. First, this research estimated the main ash acceptable amount to the existing cement plant taking into account the chemical composition of cement raw materials. Then, this article proposed planning model in the case of recycling main ash to cement resources of the existing cement plant and new eco-cement one. As a result of the model analysis, the transport to the existing cement plant by truck and coastal transport was mainly carried out, and eco-cement plant by a single municipality was not built. This paper considered the cooperative processing with the other prefectures as an eco-cement plant of the next generation type, and carried out cost-benefit analysis with the existing plant. As a result, it was suggested that we should consider the cooperative processing of eco-cement plant with other local government in the early stage, rather than increase the treatment amount in the existing cement gradually.
