In Japan, disposal of construction sludge is a serious problem because of its large quantity and the lack of waste disposal sites. Development of new waste treatment which enables recycling use is desired.<BR>This paper describes melting treatments for construction sludge. As the economics of the process depend largely on fuel consumption, factors affecting fuel consumption were analysed parametrically. Parameters include particle temperature, particle moisture, air temperature, air fuel equivalence ratio, oxygen concentration, sludge feed rate, fusion temperature of ash, and water content of the sludge. Combination of these parameters help to attain lower fuel consumption. With good combinations, sludge can be transformed into slag with only a slight increase in fuel consumption for a drying treatment. Product slag can be expected to become useful construction material.
