Topic

The focus of FLXsynErgy is to use both heat and electrical energy gained by co-digestion of sewage sludge and biogenic residues and waste products in a most efficient manner. Thus, a sewage treatment plant can contribute to the German energy transition by generating energy and providing energy storage capacities on demand. Using the existing infrastructure of municipal wastewater treatment plants can result in reduced further investment demand. Furthermore, the extent to which digesters could be used as heat storage facilities is to be investigated. Although agricultural biogas units and digesters at wastewater treatment plants are quite similar in terms of process engineering, there has been a significant  knowledge transfer gap between these two technologies. To overcome this, a Knowledge exchange should be promoted. FLXsynErgy pursues a holistic approach of identifying legal, environmental and social-ethical conflicts in order to increase acceptance and facilitate implementation of developed concepts at waste water treatment plants.

Aims

The aim of FlexsynEnergy is to provide and develop design parameters and control mechanisms in order to implement a demand driven energy production at existing wastewater treatment plants. The results obtained will be summarized in a technical guideline document. Additionally, a knowledge transfer between biogas production at agricultural biogas units and digesters will be promoted. At the same time, legal, environmental and social-ethical conflicts will be addressed to convey acceptance.

Measures
