| Outline of Final Research Achievements |
While steel scrap is characterized by a high rate of recycling, alloying elements in steel are not necessarily utilized effectively. In order to promote effective utilization of alloying elements, we developed a new mathematical model of material/substance flow analysis that considers the simultaneous presence of multiple materials and multiple substances. Results of its application under alternative scenarios show the substantial potential of effectively utilizing alloying elements and the importance of paying due attention to qualitative aspects of recycling, which was made possible by an indicator based on the amount of energy saved by effective utilization of alloying elements.
