The “Woche der Umwelt” will take place in Berlin from 4 to 5 June 2024. The RePhoR joint project Klima-PhoNds will be there as an exhibitor.

Together with the German Federal Environmental Foundation (DBU), Federal President Frank-Walter Steinmeier is organising the Environment Week in the park of Bellevue Palace.

This year, the RePhoR joint project KlimaPhoNds will be exhibiting at the event, using the example of the Northeim sewage treatment plant to show that the future phosphorus recovery obligation can be met in a way that is climate-friendly, resource-efficient and cost-effective.

KlimaPhoNds pursues a decentralized phosphate extraction in wastewater treatment plants, and based on this, a centralized refinement of the phosphate precipitation products to high-quality phosphoric acid, ammonia water and magnesium chloride. The climate neutrality is achieved by a nearly heat-neutral drying process with fluidized bed evaporation drying. The result is a fully dried, low-phosphate sewage sludge that can be recycled without residue and used in the cement industry for material and energy generation. A prerequisite for enough P-depletion in the sewage sludge is an optimized bio-P-elimination at the sewage treatment plant. In the first of two phases, the bio-P elimination at the Northeim wastewater treatment plant is maximized. If enough Bio-P fixation is successfully demonstrated, phase 2 will demonstrate the processing of the precipitation products to different raw materials, the almost heat-neutral drying and the utilization of dry sewage sludge as fuel and raw material on a technical scale.
