Personal profile


All activities are formulated within the framework of climate change adaptation and mitigation in a circular economy perspective – as a framework to optimize future production and consumption. A main question is how to secure closed mass-flows by linking technology and biology to a higher extend. The general thinking is that we don't maximize for the energy carrier; we don't maximize for specific residual quality parameters - by being a little bit inefficient with each, we approximate nature and get a more complete and efficient cycle. Currently running research projects focus on bioenergy technologies, feedstock available and energy technology residual management strategies for nutrient conservation and carbon sequestration to safeguard long term soil fertility. Stronger linkages between the energy and the food sectors are in focus.


I am associated with the Technological and Socio-economic Planning education program (TekSam)

Project supervision: I have supervised students throughout my career within a wide spectrum of topics such as climate change, mitigation and adaptation; greenhouse gas emissions, bioenergy technologies, recycling of bioenergy residuals, biochar, phosphorus cycling, nitrogen cycling, symbiotic nitrogen fixation, crop production for food and feed, cropping diversification, water, nutrient leaching, …

Lecturing: I have been lecturing within subjects like climate change adaptation and - mitigation, bioenergy and substitution of fossil energy , biogas, thermal bioenergy technologies, circular thinking, biological cycles, nutrient cycling, nitrogen dynamics, nitrogen fixing crops, phosphorus and plant availability, self-sufficient and self-regulating plant production systems, diversity , organic farming, waste water treatment and recycling of nutrients

I am involved in teaching and project supervision in the International Bachelor Study Program in Natural Science (NatBas) and the Humanistic Technological Bachelor Study Program (HumTek)
