Steel production & environmental impact - GreenSpec

8 The environmental impact of steel production Steel production has a number of impacts on the environment, including air emissions (CO, SOx, NOx, PM2), wastewater contaminants, hazardous wastes, and solid wastes The major environmental impacts from integrated steel mills are from coking and iron-makingThe Modern Steel Manufacturing Process - The Balance,The Modern Steel Production Process Today, steel production makes use of recycled materials as well as traditional raw materials, such as iron ore, coal, and limestone Two processes, basic oxygen steelmaking (BOS) and electric arc furnaces (EAF), account for virtually all steel productionWater Reuse Strategies: Steel Industry Case Studies,The first step in treating the cooling waters used in a steel mill or steel processing plant is to thoroughly understand the water characteristics, systems, contaminants loading, treatment systems used and their effectiveness, retention times, and water quality requirements
