In this work, a dynamic material flow analysis (MFA) was conducted to estimate the global flow and in-use stock of steel for 42countries until 2010. The growth of the future in-use stock and demand for steel for three products (civil engineering, building, and vehicles) towards 2050 was also estimated under the concept of "stocks-driven flows", considering the economic and population growth in every country. Especially, the country differences were considered in estimating the future demand for steel for building.In addition, we analyzed the steel scrap generation in each product and in every country up to 2050, and investigated the steel use potentials by using waste input-output material flow analysis (WIO-MFA).
