Efficient use of material

Recovered by-products can be recycled during the steelmaking process or sold for use by other industries. Use of by-products supports the sustainability of the steel industry. It prevents landfill waste, reduces CO2 emissions and helps preserve natural resources.

The sale of by-products is also economically sustainable. It generates revenues for steel producers and forms the base of a lucrative worldwide industry. Some companies report a by-products utilization and recycling rate as high as 99%.

The main by-products from iron and crude steel production are slags, process gases, dusts and sludges.
