In the steel production process, tons of scales are generated as waste materials, which contain a high proportion of iron. These scales have an undesirable effect on the quality of steel production and on the number of pieces of production equipment with which they come into contact during the production process. Since scale contains a large amount of iron oxides, heavy metals, and other various elements that can be soil and water contaminants, it is necessary to manage this waste very responsibly. Currently, it is a great challenge to turn as much of this waste as possible into a by-product and thus to find suitable processing for further use. The Slovak Republic, as a member of the European Union, is obliged to comply with European Union regulations. The European Union directive concerning waste is strictly enforced. By 2030, waste suitable for reuse or recycling should not be accepted for landfill, except where landfilling provides the best environmental result.
