Iron and steel slags are byproducts of the iron and steel industry and provide an important source of raw materials for construction and road building. Slags are used in road bases, asphalt concrete aggregates, concrete aggregates and products, glass manufacture, mineral wool, railroad ballast, sewage treatment, and soil conditioning. In 1990, the Federal Environmental Protection Agency (EPA) permanently retained iron and steel slags in the Bevill amendment, or mining waste exclusion, under the Resource Conservation and Recovery Act (RCRA). Iron and steel slags are, therefore, not subject to Federal regulation as hazardous wastes. Research during the year emphazied the use of granulated slag, particularly in cement. The Australasian Slag Association was formed in Sydney, Australia, to expand the already considerable use of slag in the Australian and Asian markets. Domestic consumption of iron slag showed a moderate increase when compared with that of 1989, while the consumption of steel slag stayed at the increased level that it had reached in 1989.
