Recycling ferrous metals, such as scrap iron and steel, can save up to 75 percent of the energy needed to make products from raw materials.
The steelmaker benefits from slag recycling by avoiding the cost of landfill. The community benefits, too. Slag is a man-made mineral, therefore its use as an aggregate in place of a natural aggregate product avoids the environmental footprint from quarrying.
This nonmetallic slag material can either be crushed and screened for aggregate use (steel slag aggregates), or sintered and recycled as flux material in the iron and steel furnaces. Steel slag aggregates generally exhibit a propensity to expand.
