The EU project FlashPhos is taking a pioneering approach to recover phosphorus from sewage sludge ash in its elemental form (P₄). The process is already being implemented and tested at pilot scale, aiming to demonstrate a sustainable, circular alternative to...

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,...
