On April 8, 2025, the FlashPhos consortium met at the University of Stuttgart for a General Assembly Meeting. The host of the meeting was the Institute for Sanitary Engineering, Water Quality and Solid Waste Management (ISWA), project leader of FlashPhos. The project partners presented new results to the consortium as well as their tasks for the next few monthts.
The FlashPhos project aims at driving the sustainable production of high-quality white phosphorus (P4) and other valuable raw materials from sewage sludge and is co-funded by the European Commission. The project follows an economically and ecologically sound and climate-friendly circular economy approach, with all output materials being used in the European industry. The FlashPhos consortium, coordinated by the University of Stuttgart, is a multi-disciplinary European team composed of large industrial companies, SMEs, NGOs, and academic institutions. The 17 partners, located in Austria, Germany, Belgium, Italy and Spain cover the full range of expertise in waste management, design and operation of thermochemical plants as well as cement and phosphorus production.
“The pilot plant is almost fully errected and the flash reactor will shortly be ready for commissioning. We are exited for the final completion. The first full-scale FlashPhos pilot plant will be finalized soon.“
– Christian Schmidberger, researcher at the University of Stuttgart

“This General Assembly was very important for the consortium. FlashPhos was extended for another year, to be able to meet the project’s goals and to exploit the results. Having only one year to go, now is the time to discuss about a roadmap for the future of the FlashPhos concept.”
– Luigi Di Rienzo, FlashPhos’ Industrial Project Manager at Italmatch Chemicals
The day after the General Assembly, a workshop including a site visit of the FlashPhos pilot Dryer-Grinder took place, also open for external visitors and interested stakeholders. Find more information about the exciting event here.
