We have developed our innovative sludge2energy to utilize sewage sludge by an energy self-sufficient method. The process thermally utilizes sewage sludge (at the wastewater treatment plant) by incineration. Co-generated power and heat are used for dryer operation.

Other municipal waste, such as yard and park waste, screenings and compost residues, can be co-incinerated with dried sludge.

Our innovative process is a solution for sustainable waste management. The first large-scale system is installed at the wastewater treatment plant of the Bavarian city Straubing. This system’s capacity is 3,000 dry metric tons per year. The project is supported with grants by the EU within the framework of Environmental Program EU LIFE06.

Sludge mass is reduced by energetically self-sufficient drying and incineration to about 10 %. The remaining ash shall be deposited on a separate site, thus permitting later recovery of its phosphorus content.
