The World Steel Association has published a report on steel industry by-products—the result of a survey of worldsteel member companies. It looks at by-products generation rates, recycling or reuse rates, and management techniques.
The book is now available for purchase on worldsteel.org.
By-products fall into three main categories: ironmaking slag, steelmaking slag, and dust and sludge. The report outlines the economic and environmental issues surrounding steel industry by-products. It also examines the benefit by-products can create for other industries, such as cement and road-building.
The report finds that for the best-performing companies, by-products are an integral part of their business.
“This study on by-products delivers important insights and challenges for the steel industry,” said Pierre Gugliermina, Chairman of worldsteel’s Committee on Technology. “By-products generation brings significant benefits both environmentally and economically to the steel industry. Use of by-products prevents landfill waste, reduces CO2 emissions, and helps preserve natural resources.
“Recycling 100% of BOF or EAF slag is possible today, and it is achieved in the world’s main plants,” Gugliermina added. “This progress demonstrates that there is a high level of technical skill and management techniques in the steel industry. The techniques achieved by the best performers should be seen as a major opportunity for the rest of the industry.”
On average, the production of one tonne of steel results in 200 kg (in electric arc furnace steelmaking) to 400 kg (in blast furnace steelmaking) of by-products, according to worldsteel. These include slags, dusts, sludges, and other materials.
The study uses data and information covering 60 steelmaking plants in 24 countries.
The World Steel Association (worldsteel) is one of the largest and most dynamic industry associations in the world. worldsteel represents approximately 180 steel producers (including 19 of the world's 20 largest steel companies), national and regional steel industry associations, and steel research institutes. worldsteel members produce around 85% of the world's steel.
