Personal profile


My research interest is in circular economy, resources, waste, renewable energy, environmental innovation and policy/planning/regulation. I am currently working on a number of research projects dealing with:

  • Circular economy: Working with circular economy, resources, waste and sustainable manufacturing. Waste minimization and innovative exploitation of waste and by-products. Working with theories and methods for circular economy, global value chains, innovation in global production and consumption systems as well as industrial ecology and industrial symbiosis
  • Renewable energy: development of methods and approaches for municipal energy plans. Strategies for sustainable use of biomass for energy. Working with exploitation of waste and by-products from agriculture and industry for energy, district heating and transport fuels.
  • Planning, policy and regulation: focussing on Danish and international (EU) planning, policy and regulation.
