Stijn (pronounced “Stine”) is a Lecturer (Assistant professor) in Environmental Engineering at University College London. He is an expert on waste management and the circular economy. Stijn aims to drive sustainability by advancing the integration of material flow analysis and life cycle thinking in policymaking. He has worked internationally with policymakers to develop evidence and policies for reducing environmental impacts.

Previously, Stijn was a Postdoctoral Associate at the Yale Center for Industrial Ecology and a Research Associate at UCL. He was also an ABSW Media Fellow at The Times and a visiting researcher at the Department for Environment, Food & Rural Affairs (Defra). Stijn obtained his PhD from the UCL Institute for Sustainable Resources and holds MSc degrees in Sustainable Energy Technology and Public Administration from the University of Twente.

Stijn leads a research group on industrial ecology and policy. The group shows how public policy shapes the use of materials and energy in society. The research methods include material flow analysis (MFA), life cycle assessment (LCA), techno-economic modelling, and policy analysis. The group works across disciplines and in collaboration with industry and policymakers to investigate government interventions that support a transition towards a sustainable circular economy.

Stijn published widely in peer-reviewed journals including Nature Sustainability and Nature Communications. He has written for popular media including The Times, Scientific American, and The Conversation. Stijn’s research was featured in the international media, such as The Independent, ArsTechnica and La Repubblica. Stijn was the lead author of the white paper 10 Insights from Industrial Ecology for the Circular Economy (ISIE, 2023). He co-authored the textbook An Introduction to Waste Management and Circular Economy (UCL Press, 2023).
