Research Interests

For a sustainable society, our laboratory tries to unveil the dynamics of stock and flow of substances and energy

Modelling dynamic materials stock and flow
The consideration of material use is essential for a pathway to a sustainable society. Material use at present cannot be deemed `sustainable` as exhaustible natural resources and fossil fuels are being used for production and tend to trigger material dissipations at end-of-life. Therefore, in our laboratory, we aim to develop dynamic stock and flow models for environmental sustainability analyses of materials and resources. Specific research topics are clarifying the dynamic of stock and flow of substances required for the models, development of sustainability indicators for optimization, impurity accumulation during recycling, and their influences on material properties.

Develop an LCA methodology for a zero-carbon future
Recently, quantifying greenhouse gas emissions using LCA (Life Cycle Assessment) has been required by product manufacture, project implementation, and business activities. However, traditional LCAs are static assessments and do not fully consider consequential impacts on society; hence they have been unable to meet current requirements. Therefore, we develop a dynamic LCA method that considers the aforementioned stock and flow systems of materials.
