The working group focuses on the analysis and optimisation of biochemical conversion processes, with an emphasis on anaerobic processes. This includes not only the fermentation process itself but also upstream and downstream processes, such as substrate pretreatment methods, the use of additives for process optimisation, and the processing of fermentation products. Concepts for the material utilisation of fermentation products and the necessary processing methods are developed and optimised.

In close collaboration with the biogas laboratory of the BK departement, biogenic waste, residual materials, and cultivated biomass are examined for their suitability in anaerobic conversion processes. The overarching goal, within the framework of the DBFZ’s research, development, and innovation concept, is to integrate anaerobic conversion processes into the concept of a circular economy.

Main topics of the working group:

• Energetic utilisation of previously unused or insufficiently used biogenic waste and by-products in anaerobic processes
• Development of existing and new analytical methods for biomass characterisation
• Evaluation of disintegration processes to increase the methane yield or to increase process stability
• Integration of anaerobic processes into utilisation cascades
• Analysis and optimisation of anaerobic conversion processes with regard to the material use of fermentation products
