Abstract
In Japan, melting treatment for municipal solid waste has been being conducted within the industry since the year 2000. The Eco-Slag Utilization Promotion Committee was established in order to regulate the Japan Industrial Standard and to promote slag utilization for concrete and road construction material. Today, approximately 800000ton/year of slag are produced and recycled as concrete and road construction materials in compliance with the Japan Industrial Standard. With the aim of expanding its application overall, several uses for eco-slag, including sand-piling, drainage improvement, agricultural utilization and marine blocks, have been developed.
