Sewage Sludge Incineration

Enabling phosphorus recovery from sewage sludge incineration ash

Modern regulations across Europe increasingly focus on the sustainable treatment of sewage sludge and the recovery of critical resources such as phosphorus. As phosphorus is classified as a critical raw material by the EU, national frameworks are moving towards its mandatory recovery from sewage sludge incineration ash to reduce import dependence and strengthen the circular economy.

In this context, mono-incineration of sewage sludge is widely regarded as the most effective and future-proof technological pathways. Our plant concepts are specifically designed to create technical conditions for phosphorus recovery by providing well proven mono-incineration and producing suitable sewage sludge ash.

At the same time, our design reliably complies with strict European emission requirements and ensures a minimum combustion temperature of 850 °C with a residence time of at least two seconds. This combination of regulatory compliance and phosphorus-ready plant design enables operators to meet current environmental standards while preparing for future obligations.
