With this plant, to be built at the port of Hildesheim, KNRN will ensure the reliable disposal of sewage sludge and enable the recovery of valuable phosphorus. The value of the order will not be disclosed. It will be included in ANDRITZ’s order intake for the third quarter of 2025.
Dr. Jens Manthey, Managing Director of KNRN GmbH, emphasizes: “ANDRITZ convinced us with a technically advanced concept that is exactly tailored to our needs. We are very pleased to have ANDRITZ as a strong, internationally renowned technology partner at our side for the joint implementation of this project, as it involves the realization of a plant with the lowest emissions and highest environmental standards while ensuring high economic efficiency.”
ANDRITZ will supply equipment for sewage sludge reception, conveying, drying including vapor condensation, and incineration with an adiabatic EcoFluid bubbling fluidized bed (BFB) boiler system. The scope of supply also includes a multi-stage flue gas cleaning system, steam turbine, generator, water-steam cycle, and additional auxiliary systems.
The highly efficient, state-of-the-art plant with a capacity of 33,500 tons of dry matter per year will burn sludges from currently 21 municipalities in Lower Saxony, enabling a resource-efficient and environmentally friendly disposal in compliance with the German sewage sludge regulation (AbfKlärV). Mono-incineration of sewage sludge produces ash from which phosphorus can be recovered. As phosphorus is an essential but limited and non-renewable resource, the regulation requires its recycling from sewage sludge. The steam generated by the incineration process will produce electricity for the public grid and heat for the local district heating system.
“Winning this tendering procedure demonstrates our ability to meet the needs of our customers with our cutting-edge technologies,” said Benjamin Klammer, Project Manager, Sales at ANDRITZ. “We are very excited to collaborate with KNRN to implement this project and make a significant contribution to a circular economy.”
ANDRITZ’s scope of supply includes engineering, supply, erection and commissioning of the main equipment. The plant is scheduled to begin operation in December 2027.With this plant, to be built at the port of Hildesheim, KNRN will ensure the reliable disposal of sewage sludge and enable the recovery of valuable phosphorus.
