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 through substrate specific pre-treatment
- Develop new volatile fatty acids sensors and new digester feeding control algorithms
- Develop new ionic liquids and absorber
- Design and test thermally self-sufficient up flow anaerobic filter pilot systems
- Adapt small scale anaerobic digestion to Swiss agriculture addressing the application of SOFC fuel cells
- Identify and divert selected biomass streams to hydrothermal gasification for additional energy recovery
- Initiate a paradigm change in sewage and sewage sludge treatment towards energy and carbon recycling by switching from aerobic to anaerobic treatment and full nutrient recovery technologies.
