The co-combustion of sewage sludge in the Wilhelmshaven power plant has guaranteed the environmentally friendly, cost-effective and secure disposal of sewage since the end of 2004.

The conventional manner of sewage disposal, its use as a fertilizer in agriculture has been attracting increasing criticism as the pollutants contained in the sewage could wind up in the food chain through the plants it fertilizes.

Therefore, it is more cost-effective and environmentally friendly to co-combust sewage sludge along in coal fired power plants which are already equipped with modern flue gas purification technology capable of filtering out the pollutants.

For the surrounding region, this is the most attractive way to dispose of sewage in an environmentally friendly manner.

The sewage sludge from the region is added to the coal pulverisers. Metering valves in each of the five coal pulverisers ensure an even addition of sewage sludge.
