KlimaPhoNds

Joint project under the leadership of the Wastewater Process Engineering Department at CUTEC, project management: Prof. Dr.-Ing. Michael Sievers, duration: 01.10.2020 - 30.09.2023, funding provider: BMWK as part of the RePhoR announcement.

As part of its sustainability policy, the German government is placing particular emphasis on the future recycling of the element phosphorus. This substance is required by humans, animals and plants. It cannot be replaced by any other element in all living organisms.

The KlimaPhoNds concept includes decentralized phosphate extraction at wastewater treatment plants and, building on this, centralized refinement of phosphate precipitation products such as magnesium ammonium phosphate (MAP) from various wastewater treatment plants into phosphoric acid and P-precipitant recyclates as well as (virtual) regional recycling of marketable fertilizers. It aims to achieve sustainability in several respects: The planned P extraction and utilization is climate-friendly and_{reduces CO2 emissions} while at the same time being resource and cost-efficient.

The joint project is strongly application-oriented. In addition to the CUTEC research center, the partners Lukson AG (Mönchengladbach), PARFORCE Engineering & Consulting GmbH (Freiberg), Abwasserentsorgung Wolfenbüttel AöR, EBA Northeim and Knoke Industrie-Montagen GmbH (Salzgitter) are represented. CUTEC brought together the abb. AVT, RTS and TP were brought together in CUTEC, with AVT taking the lead.

The TP department is responsible for the R&D work on the calcination of MAP, i.e. the removal of ammonia, organic impurities and water, as well as the coordination of the corresponding work package.
