Sewage Sludge Incineration deferred
GKS has planned to invest € 84 million euros to prepare for large-scale sewage sludge incineration.
As recently as November 2024, everything seemed to be finalized, at least as far as the plans were concerned. The plans were in place. GKS wanted to invest 84 million euros in order to be able to burn dry sewage sludge on a large scale instead of coal in the future. It was slated to be one of only a few power plants in Bavaria to do so. That has now changed.
A shareholders meeting was recently held. On Tuesday, the GKS issued a press release. Its main point: The plans are deferred. "The planned conversion to incinerating the dry sewage sludge from the region will be postponed for the time being," it says.
The company intends to stick to its plan to phase out coal. However, this will be achieved through different means, and gradually starting in 2026. "The current CO2-intensive coal combustion will be replaced in a first step by converting to hydrogen-compatible gas boilers," GKS announced. The announcement mentions two to three gas boilers. Subsequently, at least one coal boiler will be converted to "biogenic fuels," specifically wood pellets.

Regional cooperation sets standards in the circular economy: Dried sewage sludge will partially replace coal and achieve phosphorus recovery in the future
From the end of this decade, sewage sludge must be processed and the phosphorus contained in it recovered. This is what the legislator wants. 40 municipalities from Lower and Middle Franconia as well as the Main-Tauber district have now joined forces to form the Main-Tauber-Aisch sewage sludge recycling association in order to master this task together, reports a press release. It is not only about the conservation of natural phosphate deposits, but also about the extraction of renewable energy. The power plant in Schweinfurt (GKS) and the waste-to-energy plant in Würzburg (MHKW) play a central role in the plans.
