Shifting from a linear economy to a circular economy is becoming a more important issue than ever to create values while reducing environmental impacts through effective and efficient resource use. In the circular economy session, we invite four speakers from the two institutes to cover a broad range of relevant topics from both social and technological viewpoints. Based on social trends and ongoing research projects provided by the speakers, enablers and barriers to a circular economy will be discussed.

Takanari Ouchi

Lecturer
Institute of Industrial Science
The University of Tokyo

Takanari Ouchi is a lecturer at the Institute of Industrial Science, the University of Tokyo. He received engineering doctorate in Nanoscience and Nanoengineering from Waseda University in 2011. After completing doctoral degree, he joined the Massachusetts Institute of Technology (MIT), where he developed liquid metal batteries, which are, in principle, a bi-directional electrolysis (electro-refining) cell, for application in grid-scale energy storage. While at the University of Tokyo, where he was a research associate from 2017 to 2021, he developed new smelting and recycling processes for rare and precious metals using pyrometallurgical and electrometallurgical methods. Since August 2021, he has been in his current position. Currently, he is also serving as the chairperson of the hydrometallurgy and electrometallurgy committee at The Minerals, Metals & Materials Society (TMS).

Anna Barford

The Prince of Wales Global Sustainability Fellow
Cambridge Institute for Sustainability Leadership
University of Cambridge

Anna is a social and economic Geographer. She is currently researching how work and livelihoods intersect with environmental problems and solutions. This includes studying informal work in circular systems in lower- and middle-income countries, as well as how the crises of climate change and COVID-19 intersect with young people’s livelihoods.
