Outline of Final Research Achievements

We have conducted a dynamic MFA to depict the global in-use steel stock, demand and generation of scraps from all end-uses, e.g. automobile, civil engineering, building, machinery, etc. towards 2050. We have also tried to use nighttime light images and GIS to estimate the in-use steel stocks used for civil engineering and building whose data for the dynamic MFA were not available. Then, global material flows associated with steel were investigated. Collection and use of steel scraps in developing countries were explored, and appropriate ways to use steel scraps were discussed.
