Phosphate is an essential nutrient for plant growth. In order to ensure safe and sustainable access to this important and finite raw material in Europe, recovery and recycling of phosphorus has become a major political objective within the EU. 

That’s why back in 2017, a binding regulation for the phosphorus recovery from sewage sludge in medium-sized and large sewage treatment plants was passed in Germany, which is due to come into effect in 2029.  A large number of process combinations were available to implement recovery. However, it’s not easy for wastewater treatment plant operators to distinguish between them in terms of economic efficiency, feasibility and environmental compatibility.

This is where KWB comes in with its know-how on P-recycling. With our many years of expertise, we can comprehensively analyse and evaluate both already implemented and emerging P-recycling processes. We explain the technical and economic options for P-recycling from wet sludge and sewage sludge ash that are tailored to your specific requirements and your sewage sludge. In our analyses we consider P-recovery together with sewage sludge disposal holistically. 

In addition to assessing the technical feasibility, we also provide analyses of the CO2 footprint and the economic viability of various processes. Our forecasts on the pollution load and the marketing opportunities of the recycled phosphate products will support you in upcoming investment decisions. 

With our P-recovery consulting, KWB offers independent and practice-relevant services in a market with many different processes and products.
