Since 1981, wastewater services for the city of Frankfurt am Main (SEF) have been operating a sludge dewatering and incineration plant (SEVA) at the Sindlingen site, in which the raw sludge from its two large wastewater treatment plants, Niederrad WWTP and Sindlingen WWTP, is jointly disposed of. The increasingly unreliable four-line sludge dewatering and incineration plant, in which the world’s last stack fluidised bed furnaces with integrated drying are operated, is set to be replaced by a new incineration plant at the Sindlingen site. The plan is also to retrofit a sludge digestion plant with digester gas utilisation in CHPs. The digested sludge generated will be incinerated in a new incineration plant with conventional fluidised bed furnaces with an upstream drying plant. Planning for the new digestion plant commenced in March 2014.

In August 2016, TBF was commissioned with the general planning for the new incineration plant. The plant is conceived as a two-line plant with an upstream stacking bunker and an incineration capacity of approx. 25,000 Mg dry mass per year.
