How can organic waste be used effectively – in a way that generates energy, closes material cycles, and increases regional value creation? To conclude its lecture series in the winter semester, the Technische Hochschule Mittelhessen (THM) will address a topic on Wednesday, January 14, 2026, at 7 p.m. that could hardly be more relevant in light of the energy transition, decarbonization, and resource scarcity: Renewable energy from organic waste in the context of industrial bioenergy.

The event will be moderated by Prof. Holger Rohn. Following a welcome address by Vice President Prof. Dr. Stephanie Hanrath, research and practice will be presented on equal footing: The focus will be on the collaborative project RegBioFerm by Prof. Dr. Harald Weigand, Dr. Felix Brück, Daniel Krahe, and Hannah-Sophie Tscherney, which is further developing an innovative process for the fermentation of organic waste. The THM project team will present their experimental research using a model fermenter, supplemented by process simulation and life cycle assessment. Steffen Geipert, Managing Director of the Brunnenhof GmbH composting plant, will then demonstrate how the transition from research to industrial operation can be achieved, using the example of a large-scale drum fermenter in Biebesheim am Rhein.

The free event will take place at the Forum Werkstattbühne, Campus Wiesenstraße, Building A15, in Giessen and will be streamed live. Questions and discussion contributions from the audience are possible both in person and via chat. Further information and the link to the livestream can be found at go.thm.de/ringvorlesung .
