| Research Abstract |
Recovery systems of minor metals based on local steel and nonferrous metal industries were examined. For this purpose, the potential local generation of minor metals was estimated. Their efficient collection systems were simulated. Material flows of minor metals in municipal waste treatment processes were ascertained. Then demands for minor metals in local steel and nonferrous metal industries were estimated. Results identified regions generating large amounts of minor metals, effective measures for reducing collection and transportation costs, and key regions for minor metals recycling.
