Associate Professor

David Strik is Associate Professor in Environmental Technology at Wageningen University & Research/The Netherlands. He obtained a PhD on Anaerobic Digestion from BOKU University Vienna/Austria in 2004 and an MSc Environmental Engineering from Wageningen University/The Netherlands in 1999.

Currently his research group pioneers on 'Engineering Open-Culture Waste to Resource Fermentation & Separation Biorefineries. Waste streams like heterogenous organic waste, CO2, rhizodeposits, syngas and plastics are used in fermentations as well as electricity driven biotechnologies to produce chemicals like medium chain fatty acids. The chemicals can be used a feed-additive, plant-growth promotor, or pre-cursor for biodegradable plastics, fuels and more.

The specialty areas cover: 1)  Chain  Elongation Bioprocesses & Separation; 2) Bioelectrochemical Chain Elongation; 3) Photo-bioelectrochemical Systems. These system have in common that they are all open-culture anaerobic microbial conversions on which selection pressure is applied to establish the desired bioprocess. The research group is interdisciplinary in nature. Lab and pilot-scale bioreactors are operated, the group members use applied microbiology, open-culture selection pressure principles, bioreactor design, (bio)electrochemistry, extraction, process modelling, systems engineering, MFA and LCAs. This research approach allows the development of new biotechnology-based production platforms and understanding of their impact on society and the environment. The results do contribute to a more sustainable and circular world. For instance, spin-off companies ChainCraft and Plant-e are exploiting the developments of this research.
