摘要: Steel is not elemental iron but rather a group of iron-based alloys containing many elements, especially chromium, nickel, and molybdenum. recycling expected to promote efficient resource use. However, open-loop steel could result in quality loss nickel molybdenum and/or material chromium. Knowledge about alloying element substance flow needed avoid such losses. Material analyses (MFAs) indicate the importance recovery elements. Flows are interconnected, MFAs have paid little attention interconnected materials/substances supply chains. This study combined waste input–output model physical unit analysis perform simultaneous MFA for Japanese economy 2000. Results indicated these elements policies end-of-life (EoL) vehicles constructions. Im...
