Appointment
  • Lecturer in Environmental Engineering
  • Dept of Civil, Environ &Geomatic Eng
  • Faculty of Engineering Science
Biography

Stijn (pronounced "Stine") studies how modern societies use materials and energy, and the complex interactions between the environment, economy, and society. Stijn focuses specifically on technologies and policies for sustainable waste management and the circular economy. Previously, Stijn was a Postdoctoral Associate at the Yale Center for Industrial Ecology and a Research Associate at UCL. He was a visiting researcher at the Department for Environment, Food & Rural Affairs (Defra).

Research Summary

Industrial Ecology and Policy

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


Recent and current projects

  • Techno-economic modelling of paper recycling
  • The role of life cycle thinking in public policy
  • Allocation methods for emissions accounting in aviation
  • Non-hazardous waste generation in the U.S.
  • Best practices for material flow analysis of waste


PhD students

Chi Zhang. Thesis topic: Decision-making for end-of-life construction timber in a circular economy.


Collaborators

The group collaborates with academics across UCL and internationally.

  •  UCL Institute for Sustainable Resources
  •  UCL Centre for Resource Efficiency and the Environment
  •  UCL Circular Economy Lab (CircEL)
  •  Yale University, Center for Industrial Ecology
