Conversion of biomass through anaerobic digestion and hydrothermal methanation
The biomass to biogas routes which are explored in the SCCER BIOSWEET relate primarily to the use of household, food industry, and agricultural waste to produce biogas via anaerobic digestion and hydrothermal methanation. A strong focus is hold on manure as a feedstock.
Description of Research Area
The objective of this research area is to optimize existing and to develop new technologies for microbial anaerobic digestion and hydrothermal gasification. As a result, a higher bioenergy yield from wet biomass can be realized. The following innovation challenges are being addressed:
- Increase the conversion efficiency of anaerobic digestion through substrate specific pre-treatment.
- Initiate pilot and demonstrator facilities for specific pre-treatment processes.
- Promotion and development of scenarios and technologies for in-situ biological methanation
- Adapt anaerobic digestion to Swiss agriculture addressing the need for small scale digesters and the application of SOFC fuel cells
- Identify and divert selected biomass streams to hydrothermal gasification for additional energy recovery
- Initiate a pilot facility for hydrothermal gasification of biomass
- Develop analytical methods and instruments to support process control in anaerobic digestion and hydrothermal gasification
