The next RePhoR filming continues: this time at the SATTELITE joint project in Hildesheim and Nienburg. After the last two filming dates at DreiSATS and P-Net, we were able to continue together with the team from Hupp-Dobusch in Lower Saxony. Together with the coordinator from ISAH Leibniz Universität Hannover we visited the LUH test facility and the semi-technical test facility. Prof. Stefan Köster answered our questions in front of the camera about the aims of the project, while Dr.-Ing. Erwin Voß, CEO of Stadtentwässerung Hildesheim, and Dr.-Ing. Jens Manthey, Managing Director of KNRN, provided insights into the further processes on site in Hildesheim. The filming was prepared and accompanied by Dr.-Ing. Maike Beier, coordinator of the SATELLITE project, Johannes Reiter and Torben Martens from ISAH and Miriam Müller from SeHi. A big thank you to the entire team for a great day of filming!

As part of the BMBF funding programme RePhoR (Regional Phosphorus Recycling), the TransPhoR project is producing a total of seven short films about the joint projects. The films provide a lively insight into the different approaches of the projects.

The Satellite project offers a concept for the implementation of a comprehensive intermunicipal network for the joint planning and management of plants in regional centres (treatment plants with more than 50,000 inhabitants) and their satellites (treatment plants with less than 50,000 inhabitants) for regions with a strong agricultural character. In addition to the treatment of sewage sludge, the aim is also to integrate relevant agricultural nutrient sources (liquid manure, biogas plants). The project is coordinated by the ISAH at the Leibniz University of Hannover and is carried out together with the partner institutions BIORESTEC, Göttinger Entwässerungsbetriebe, Kommunale Nährstoffrückgewinnung Niedersachsen GmbH, Kreisverband für Wasserwirtschaft Nienburg, Landwirtschaftskammer Niedersachsen, PARFORCE GmbH, Raiffeisen Agil Leese eG, R-E-Pro Ingenieurbüro Dr Sabrina Breitenkam, SF-Soepenberg GmbH, Stadtentwässerung Hildesheim and the town of Pattensen.

Struvite precipitation as an attractive option for phosphorus recovery – short report from a P-Net event

Struvite precipitation as an attractive option for phosphorus recovery - short report from a P-Net event

On February 22, the possibilities of P recovery via struvite precipitation were discussed and classified at an event in Braunschweig. The event entitled “Struvite precipitation as an attractive variant of phosphorus recovery – an offer to exchange process engineering experience” was organized by the research association “P-Net – Regional Network for Resource Efficient Phosphorus Management”.

At the event, it became clear that the advantages of this phosphorus extraction must be made more visible; there are several providers of processes that are almost ready for the market. Struvite fertilizer is also a valuable product for agriculture. In addition, there is still a lot of work to be done by the players: The production volume, for example, has so far been rather small, and wastewater treatment plants would have to adapt their process technology and make investments.

The exchange in Braunschweig helped to discuss the developments and open questions and to drive the research work forward. If you are interested in details and an exchange on the topic, please contact pnet@isoe.de.

German Phosphorus Platform DPP e. V. publishes new policy memorandum on phosphorus recovery

German Phosphorus Platform DPP e. V. publishes new policy memorandum on phosphorus recovery

The German Phosphorus Platform DPP e. V. has published a policy memorandum on phosphorus recovery. It analyzes and evaluates how Germany intends to recover phosphorus from sewage sludge by 2029 in order to make the use of resources more sustainable.

The German Phosphorus Platform DPP e. V. recently published its policy memorandum on phosphorus recovery 2023/24. This memorandum provides a thorough analysis of the pressing issues and presents concrete recommendations for action to enable phosphorus recovery from sewage sludge by 2029. By clearly identifying obstacles and recommending solutions, the DPP provides valuable insights for policy makers, industry stakeholders and the public.

A central concern of the memorandum is the link between recovery and use of phosphorus to ensure an efficient economic cycle. Issues such as the Fertilizer Ordinance and the status of waste in the Closed Substance Cycle Waste Management Act are addressed in order to improve the prospects of implementation.

The German Phosphorus Platform DPP e .V. sees the policy memorandum as a starting point for further dialog with various interest groups along the value chain. It offers itself as a constructive platform for discussing the theses and recommendations set out in the memorandum in an interdisciplinary and cross-sectoral manner.

Further information and details on the DPP’s recommendations can be found on the website of the German Phosphorus Platform DPP e. V.: https://www.deutsche-phosphor-plattform.de/pressemitteilung-politikmemorandum-zur-phosphor-rueckgewinnung-2023-24-der-deutschen-phoshor-plattform-dpp-e-v/
