D6.8 - Demonstration of struvite extraction
Sewage sludge is produced as an unwanted byproduct of wastewater treatment which can be used as a secondary raw material for construction products. It is also an important source of Phosphorus (P), a critical raw material. With the Phosphorus recovery pilot plant developed within the CINDERELA project we demonstrate that it is possible to recover significant amount of the P (as well as nitrogen and other valuable nutrients) by source-seperation of the urine from the rest of the sewage stream. As a concequence (i) the need for costly P elimination at the wastewater treatment plant, and (ii) the amount of this valuable resource that ends up in the sewage sludge can be reduced.
