Outline of Final Research Achievements	This study revealed the linkages between national resource consumption (Fe, Cu, Ni) and global impacts by using a global link input-output model (GLIO) and knowledge to increase the resource efficiency in metal recycling based on metallurgical thermodynamic approach. This study also revealed the fundamental importance of metal recovery from waste to avoid dissipations of resources. Possible options include the development of a sorting process for metal scrap aimed at alloy-to-alloy recycling. We also discussed measures for ameliorating or relaxing the differences between the grades of secondary materials and grade of raw material in metallurgical industry; measures such as a) upgrading the quality of pre-consumer materials by removing impurities, b) adjusting the quality of secondary materials by mixing and diluting, and c) relaxing the limits on impurities by refineries can be considered to close the loop for metal cycle.
