Brief Description of Research
- Material flow and stock accounting and lifecycle assessment for sustainable resource management
The demand-and-supply balance of exhaustible resources, including rare and precious metals, has been changing drastically through the influence of factors such as the remarkable progress of Brazil, Russia, India, and China (BRICs) and resource oligopoly of major metal resource companies. Japan has the world’s highest demand for rare metals, and at the same time, it is a supplier of high-value added materials (electronic materials, steel, etc.) and highly-functional products(electrical and electronic equipment, automobiles, etc.). However, Japan depends on foreign countries for most of its requirements of rare metals. A stable supply of metal resources is the most important issue for further development of the Japanese industry. This study investigates material flows and stocks, primarily of common metals such as iron, aluminum, and copper, and those of rare metals such as manganese, molybdenum, and indium that accompany the element flows of common metals and analyzes the demand-and-supply balance of these metals. The effects of improvements resulting from changes in material and recycling technologies and social structure are quantified.

- Metal resource recyclability for material strategies based on thermodynamic analysis
In Japan, as a resource importing country, strategic resource and waste management are absolutely necessary. The promotion of material recycling is demanded as a middle-term and long-term strategy for securing resource supplies. Material recycling of such metal resources is supported by both ferrous and nonferrous metallurgical industries.In metallurgical process, metal materials are produced using secondary resources (by-products and waste materials) as raw materials, in addition to various ores and natural resources. To make a quantitative argument related to the feasibility of collecting metal resources from secondaryresources, this study presents the following. 1. It identifies the element distribution among the slag phase, gas phase, and metal phase in metallurgical process. 2. It is designed to develop a method to evaluate the metal resource recyclability from secondaryresources based on thermodynamic analysis.
