In a test environment, the high-quality energetic recovery of various biogenic residue combinations is to be realized with this demonstrator in order to confirm the functional principle.
In addition, alternative process conditions and process variants for a large number of possible raw materials and raw material combinations (raw material matrix) are to be developed in order to achieve great flexibility and stability of the process with regard to the raw materials used.
In order to combine the system components into a functional overall system, extensive research, coordination and optimization of the individual process steps as well as the overall process is necessary. In addition, there is experimental testing and the development of process variants for the various raw materials and raw material combinations. Both are the core of the research and development work in the project.


The aim of the project "Conversion of biogenic residues into product gas by pyrolysis, shift and microbial methanogenesis" (acronym: BiRG) is to test a demonstration system capable of permanent loads to check the application of microbial methanogenesis (the so-called methanogenesis) following a pyrolysis process and a water-gas shift reactor (WGS reactor).
