Seiji Hashimoto (橋本 征二) has been a Professor at Ritsumeikan University since 2011, after he was appointed as a Senior Researcher at National Institute for Environmental Studies, a Visiting Associate Professor at The University of Tokyo, a Visiting Fellow at Yale University, etc.
He studies assessment methodologies and system design for sustainable resource and waste management, looking at whole system comprehensively from extraction of resources through disposal of wastes.
He was a Lead Author of Waste Management Chapter in the Fourth Assessment Report of Intergovernmental Panel on Climate Change (IPCC) (2004-2007), a member of International Resource Panel (IRP) of the United Nations Environmental Programme (UNEP) (2015–), a Councillor for International Society for Industrial Ecology (2009-2011), an Associate Editor of Material Flow Analysis papers for Journal of Industrial Ecology (2009-2016), and an editorial board member of Resources, Conservation and Recycling.
He received a doctoral degree from Graduate School of Engineering at Kyoto University, Japan.

Better and more efficient production and use of natural resources can be one of the most cost-efficient and effective ways to reduce impacts on the environment (including pollution) and advance human well-being.
A key question that relates to the very broad and intensive use of metals is whether society needs to be concerned about long-term supplies of any or many of them. To examine this question, this reports reviews 54 studies on the topic.
A global move to a Product-Centric approach, in which recycling targets specific components of a product and devises ways to separate and recover them, is essential. This report addresses the challenges of recycling increasingly complex products.
Low-carbon electricity generation could help meet demand while reducing climate change effects. But new technologies could create new environmental problems. This report aids informed decision-making about energy technologies, infrastructure and optimal mix.
