Section of Environmental Biotechnology and Bioenergy
The Section of Environmental Biotechnology was established in 1994. Our experts from the fields of biotechnology, microbiology, environmental sciences and process engineering are involved in both research and teaching.
Our core competencees include microbiological processes for the recovery and utilisation of biomass, organic waste and wastewater to produce higher quality products. The closing of material cycles and the use of renewable energy are the focus of our work.
The work performed in the Centre includes practice-oriented and applied research at laboratory and pilot scales, technology optimisation and feasibility studies.
The Centre has excellent networks throughout Switzerland and internationally. Furthermore, through our involvement with SCCER Biosweet, we are also a part of the Swiss Competence Center for Energy Research.

We have many years of experience in determining and interpreting the biogas and biomethane potential (BMP) of substrates and substrate mixtures. We ferment a representative sample of the substrate under standardised conditions (so-called BMP tests or fermentation experiments) and measure the amount of methane released. It is also possible to determine the residual gas potential, and thus estimate methane emissions, using this method.
We carry out the BMP tests in our laboratories according to international standards (VDI 4630) using AMPTS (Bioprocess Control).
We determine the aerobic degradability of substances or biodegradable materials (bioplastics) in wastewater, digestate, compost or soil by means of respirometric testing according to EN ISO or OECD 301 standards.
In the area of exhaust air we are involved ...
- biodegradation of components in gas and exhaust air flows (e.g. desulphurisation, removal of ammonia)
- odour reduction using microbiological degradation processes
- Emission reduction for biogas & composting plants
