Unveil the dynamics of stock and flow of substances and energy

Modelling dynamic materials stock and flow

The consideration of material use is essential on the pathway to a sustainable society and net-zero emissions. Material production, use, and waste management encupsulate mining of exhaustible resources; energy consumption originated from fossil fuels; and material dissipation at the end-of-life, which is not a sustainable material use.

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 dynamics of stock and flow of substances required for the models, development of sustainability indicators for optimization, impurity accumulation during recycling, and their influence on material properties.

Develop a LCA methodology for a zero-carbon future

Recently, in many cases of product production, project implementation, and other business activities, it is required to quantify greenhouse gas emissions by LCA (Life Cycle Assessment).

However, traditional LCA methods are static assessments, and do not fully consider the consequential impact on society ; hence do not meet current needs. Therefore, in our laboratory, we develop a dynamic LCA method that considers the above-mentioned stock and flow systems of materials in society as a whole.
