- The order value is in the low three-digit million-euro range.
- The plant will start operation in November 2028.
- It will treat 36,000 tons of dry matter annually from over 70 municipalities.
- Phosphorus recovery aligns with the German Sewage Sludge Ordinance effective 2029.
Project Overview
ANDRITZ has secured an order to build a sewage sludge mono-incineration plant for RBB in Germany. The project is valued in the low three-digit million-euro range and will be included in the order intake for the third quarter of 2025.
Technological Features
The plant will incorporate a flue gas condensation system and heat pumps to enhance energy efficiency. It will use an adiabatic EcoFluid bubbling fluidized bed boiler system for incineration, along with a multi-stage flue gas cleaning system, steam turbine with generator, and various auxiliary systems.
Capacity and Compliance
Designed to process 36,000 tons of dry matter annually, the plant will serve over 70 municipalities in Baden-Württemberg. It complies with the German Sewage Sludge Ordinance, which mandates phosphorus recovery from sludge starting in 2029.
Environmental Impact
The plant will enable phosphorus recovery from incinerated ash, supporting fertilizer production and the circular economy. It will also generate electricity for the public grid and supply heat to the local district heating network.
Timeline
The plant is scheduled to begin operations in November 2028.
