On June 6, 2024, we were visited by four Australians from Melbourne. Their mission: to find an innovative and definitive solution for sewage sludge treatment for the 5-million-inhabitant city of Melbourne. To this end, the pilot plant of the Frohnbach Special Purpose Association was visited. Dr. Heinrich and Mr. Kraus detailed the process and provided impressive insights into the process of biomass drying and pyrolysis.
