Abstract

In this work, a dynamic material flow analysis (MFA) was conducted to estimate the global flow and in-use stock of steel for 4 machines (engineering and construction equipment, agricultural machinery, fans and pumps, and conveyance machines) in 42 countries until 2050. Concerning 3 machines (engineering and construction equipment, fans and pumps, and conveyance machines), the growth of in-use stock and demand for steel was estimated based on the historical growth in Japan until now. For agricultural machinery, the growth of in-use stock and demand for steel was estimated based on the historical growth of steel in 42 countries until now. It was estimated that the in-use stock, demand and discard of steels for these machines would be 1.4-1.7 billion t, 100 million t and 80-100 million t, respectively.
