Seiji Hasjimoto’s research interests include assessment methodologies and system design for sustainable resource and waste management, from extraction of resources to disposal. He is a Professor at Ritsumeikan University, Japan.

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.
