FlashPhos at ESPC4 and PERM5

Jun 17, 2022

From June 20th – 22nd, 2022, the FlashPhos project is present at the 4th European Sustainable Phosphorus Conference 2022 (ESPC4) and the 5th European Phosphorus Research Meeting (PERM5) in Vienna, Austria. ESPC4 and PERM5 gather companies, regional and national authorities, the scientific community and other stakeholders for expert discussions on phosphorus and nutrients sustainability actions and policies.

FlashPhos is a €15 million EU industrial innovation project aiming to demonstrate at a large scale a thermochemical process to sustainably produce high-quality white phosphorus (P4) using sewage sludge as input material. FlashPhos will then be the first and unique technology in Europe to produce white phosphorus for the chemical industry, providing at the same time a solution for the problematic sewage sludge disposal. It is expected that FlashPhos plants will be able to cover 50% of the European P4-demand by 2040. This will be possible by recycling 15% of the sludge currently generated in Europe in an economically and ecologically sound and climate-friendly circular economy process.


FlashPhos project coordinator University of Stuttgart (Germany) will present the FlashPhos project during both ESPC4 and PERM5. In the project, the University’s Institute for Sanitary Engineering, Water Quality and Solid Waste Management (ISWA) is in charge of materials management for the FlashPhos pilot, collects and processes information on European markets of sewage sludge and other input materials and contributes to environmental and socio-economic impact assessments. Matthias Rapf from ISWA will introduce the FlashPhos project during the ESPC4 Plenary on June 21st from 9:00 – 10:30 am and during the phosphorus recycling research & technology update at PERM5 on June 22nd from 9:00 – 10:30 am. In addition, Lukas Pohl will speak on the industrial demonstration of the FlashPhos process and the state of the project after one year at ESPC session “Emerging nutrient recovery technologies” on June 21st from 11:15 am – 12:45 pm. On June 22nd, Lukas Pohl will present the FlashPhos process in relation to critical resources and zero waste from sewage sludge during the PERM session “New technologies for nutrient recovery” from 1:30 – 3:00 pm.


In addition, Sander Arnout from InsPyro (Belgium) will speak at PERM5 on June 22nd, during the same session from 1:30 – 3:00 pm, on the thermal behaviour of sewage sludge aiming at white phosphorus recovery on behalf of the FlashPhos consortium. InsPyro is a consultancy company, aiming to conceptualise new processes and improve existing ones for sustainable materials production and recycling. Within the FlashPhos project, InsPyro leads component testing and lab-scale experiments, carries out thermodynamic calculations and builds the virtual FlashPhos plant for process simulation.
