Rottweil-Hausen biogas cogeneration plant
ENRW has been operating a biogas thermal power station in the Hausen district of Rottweiler since the end of 2007. The biogas cogeneration plant was developed on the basis of a scientifically supported citizens' report and generates environmentally friendly electricity for around 1,400 households and heat for around 170 residential buildings in Rottweil-Hausen every year. Only local farmers supply corn, grain and grass. Fermentation produces biogas, which is converted into electricity by combined heat and power plants. The digestate is then returned to the fields in a material cycle.

Utilization of sewage gas and sewage sludge
ENRW operates a heating and power plant operated with sewage gas in the Rottweil sewage treatment plant. The sewage sludge is first dewatered and then dried using the waste heat from a biogas plant. The resulting product has roughly the same calorific value as lignite. In the Dotternhausen cement works, the dried sewage sludge from Rottweil is used as a regenerative fuel, the ash can be used in cement production.
