The global demand for metal resources has been sharply increasing by economic growth, and the issue of sustainable resource management has also been increasingly recognized. In order to optimize the material cycles and increase resource efficiency, material flow analysis (MFA) is a powerful tool to understand the resource consumption and material cycle in the national economy. However, MFA cannot provide technological information on the recoverability and/or removability of elements from secondary resources. This study proposed a combined application of MFA with thermodynamic analysis for sustainable resource use, and conducted detailed MFAs of metals, such as nickel, chromium and molybdenum, that were concerned with thermodynamic properties of elements
