Subject of research
1.	Interdisciplinary Research on Sustainable Energy and Resource Use

Research summary
Interdisciplinary Research on Sustainable Energy and Resource Use The research interests of our group may be encapsulated as "Sustainable Energy and Resource Use". Our laboratory is grappling with the development of materials and processes, and their environmental impact assessment from multidimensional (present, past and future; local, domestic, and global) viewpoints. More academically, our research fields consist of natural science (materials science, thermodynamics and transport phenomena, etc.) supported by industrial ecology (material flow analysis, life-cycle assessment, environmental system engineering, etc.), and sometimes experimental archaeology. Current targets are metals (iron, nickel, zinc, copper and related scarce metals), phosphorus and foods, and related processes. With regard to these particular products, we focus not only natural mines but also urban mines that were thought of as waste.

Present specialized field
Thermal engineering, Environmental dynamic analysis, Environmental impact assessment, Environmental conscious materials and recycle, Design and evaluation of sustainable and environmental conscious system, Nanomaterials engineering, Physical properties of metals/Metal-base materials, Metal making/Resorce production engineering, Earth system and resources engineering (Keyword：Ferrous materials, nonferrous materials, rare metals, phosphorus, materials science, thermodynamics, solid state physics, thermophysical properties, mechanochemistry, Food production, photocatalysts, recycling, life cycle assessment, material flow analysis, total material requirement ,sustainable society, industrial ecology, environmental system engineering, experimental archaeology)
