Abstract

With the diversification of the solid waste disposal by local governments, the city of Sapporo has advanced its waste disposal systems through both incineration and landfill by starting up a solidified fuel processing 5 years ago. Having launched these disposal systems, Sapporo City found it had a particularly high ratio, with 60% of its total solid waste amount being business-oriented. After 5 years in operation, while overcoming various problems, the program has been running and can now maintain a stable supply of good quality fuel. In particular, to secure high quality raw materials, they have had to do things such as establish a difference in cost for disposal by incineration and landfill, and resource processing facilities. They are also making efforts to improve equipment, and to maintain better quality goods and operating conditions. As a result of these efforts, they have finally made stable operations possible. However, as always there are still many issues that will upset the new system, and they must create a cooperative structure that includes the demand side.

Key words: fuel quality, raw material acquisition, demand-based cooperative structure
