Slag recycling recovery

Germany is one of the model countries in slag recycling. In 2018, the country produced 27.271 Mta of pig iron and a total of 42.435 Mta of crude steel. This corresponds to 30 % of the total pig iron production and 25.3 % of crude steel production in the EU28.

Industrial Solid Waste Recycling [ Slag ] M&C

Slag generally comes from factories such as cement plants, thermal power plants, smelters, etc., mainly from the following sources: ① Oxides formed by oxygenation of various impurity elements (such as Si, Mn, P, etc.) contained in iron and steel (hot metal, scrap). ② The slagging materials such as lime, fluorite and dolomite, that are added

Life Cycle Assessment of Internal Recycling Options of

Jul 01, 2011 The internal recycling process of BOF slag which is one of the huge solid wastes from iron and steel industry was emphasized. Based on the four scenarios of different internal recycling strategies for BOF slag, life cycle assessment (LCA) as a valuable tool for industrial solid waste management was applied to analyze the contribution to reducing environmental impacts and

Slag: From By-product to Valuable Construction Material

Recycling slag minimizes waste and disposal costs, reduces energy use, extends furnace life, and lowers the amount of additives needed to make slag. The concerns with slag recycling are that first, because slag can contain environmentally hazardous materials, it must be analyzed for elemental composition before reuse.
