When people think of critical raw materials, they might picture rare earths, lithium, or even oil. But there’s one element quietly running the show behind the scenes of modern industry: white phosphorus (P₄). You won't see it in shops or on labels, but P₄ is a key...

Building on the simulation models presented in previous posts (Multiphase Flow Model, and FlashReactor and Refiner Simulation), which described sewage sludge combustion in the FlashReactor, the modelling efforts at TU Graz have recently shifted toward understanding...

In this article, we present the FlashReactor section of the FlashPhos pilot plant as a whole. We provide insights into its layout, key components, and technical setup, and explain how the individual units interact to turn sewage sludge into valuable raw materials....

"Running a pilot plant isn’t just science – it’s a rollercoaster. It takes months of planning, countless experiments, and endless hours of data assessment. But in the end, every challenge faced, every milestone reached, every laugh (and even the tears) becomes part...

When we think about innovation in the circular economy, we often imagine big research teams, large institutions, and corporate labs. But sometimes, the biggest ideas come from the smallest players.  One of the partners in the FlashPhos project is MITechnology,...

As the global push for climate neutrality accelerates, the cement and concrete industry finds itself at a pivotal crossroads. Responsible for a significant share of industrial CO₂ emissions, the sector is under growing pressure to decarbonize its processes and...

On May 7, 2025, FlashPhos hosted a hybrid workshop at Dyckerhoff’s cement plant, exploring a promising and complex question: how can phosphorus recovery be effectively integrated into the cement industry? This question brought together experts from research,...

On April 9, 2025, an inspiring FlashPhos workshop took place at the University of Stuttgart. Concluding with an expert panel, it did not only include interesting presentations, but also fruitful discussions and insights from industry and policy. However, the...

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...

To promote the full and equal access and participation of females in Science, Technology, Engineering, and Mathematics (STEM), the International Day of Women and Girls in Science takes place on 11 February every year. Within FlashPhos are many inspiring women who...
