Environmental Problems in the Municipal Waste Treatment

Abstract

　　　Waste treatment in Japan has been conducted mainly by incineration for the purpose of ensuring proper treatment. On the other hand, recently in Europe, there is a tendency to promote incineration for the purpose of reducing landfill and thermal recycling. Introducing the approach to environmental problems in incinerator, efforts to suppress generation using reaction simulation for fuel-NOx in combustion chamber, and efforts to use agricultural fertilizer as an extension of slag applications in melting system. In waste treatment, it is necessary to optimize the entire process in consideration of regional characteristics and economic efficiency for a series of processes such as generation, collection, intermediate treatment (e.g. incinerator), and landfill.
