Abstract

This study investing ates the relationship between solid waste management plans and higher rank plans,estimation methods for quantity and characteristics of collected wastes and the possibility of advanced utilization of waste heat from refuse and RDF (refuse-derived fuel) via electric power generation. The importance of systematization of waste processing plans in higher rank plans such as basic plans and city plans and citizen participation from the start of the formation of higher rank plans were indicated. It was shown that the method whereby quantity of collected wastes is estimated by physical composition is preferable. Improvement of waste composition characteristic data and thein database creation are also important. Case studies were undertaken of power generation which had very high efficiency. It was indicated that rise in price of selling excess power and development of corrosion-resistance boiler tube materials would make the system more popular.

Key words: waste processing, higer rank plan, estimate, heat utilization
