Academic Interests

Our academic background is materials science and engineering. Currently, we are involved in a field of Industrial Ecology which focuses metabolisms of materials and energy in the anthroposhere. The goal of our studies is achieving a sustainable use of materials. Although the present society relies on many kinds of exhaustible resources, a sustainable use of materials can be achieved by less exhaustible resource consumption than their capacities of the earth.
Our approach is a system analysis on the basis of life-cycle and bird’s-view perspectives and knowledge and doctrines in the field of materials science. Due to combination of materials in products, coproduction of metals from an ore and many different kinds of materials which have been developed so far, the systems of using materials is quite complex. Some aspects of the systems have been modeled in forms of mathematical equations; such as dynamic material flow analysis, absorbing Markov chain model, materials pinch analysis, and so on. Many of our publications contributed to reports from International Resource Panels, United Nations Environment Programme (UNEP). Furthermore, another achievement has been contributed to econometrics, especially to input-output analysis.
In order to achieve a sustainable use of materials, we figured out two key measures to make a current system push forward, that is, enhancement of recycling and letting efficiency of materials stocks in use be increased. On the other hand, we still have a significant gap between a current use of materials and a sustainable use of materials. On the basis of quite a long term perspective, a very basic question might be the relations between human needs and use of materials for them.
At present, we are mainly working on following three topics;
- recycling of metals and other materials,
- management of materials stock in use, and
- exploring relations between functionings of materials and human needs.
