Environmentally Sound Treatment and Recycling Technology of Municipal Solid Waste.

It is important to construct and proceed the recycling-society, which has the function to reduce, reuse and recycle waste products/materials. This paper discusses what combination of treatment process in municipal solid waste control should be selected to attain this object. First, it is shown that the key point is the selection between a system, where all combustible refuse are burnt and melted altogether to minimize amount of landfill waste and another system, where a production rate of recyclable resources is maximized. Secondly, treatment processes of environmental soundness and resource recycling are introduced such as a raw materials recovery process from waste glass, can and PET bottles, a ferrous metal recovery process from bulky wastes, a gasification-melting from combustible refuse, a cement-production from incineration residue, a biogas-production, composting and a mash-production from garbage and a carbonization and a refuse-derived-fuel production from combustible refuse. Finally, cost and life cycle assessment is presented to the present system as a control and two future systems.
