FlashPhos is a HORIZON 2020 project funded by the European Union that will demonstrate at a large scale a thermochemical process to sustainably produce high-quality white phosphorus (P₄) and other valuable raw materials using sewage sludge as input material. FlashPhos follows an economically and ecologically sound and climate-friendly circular economy approach. All output materials of FlashPhos will be used in the European industry, some of them substituting critical or CO₂-relevant raw materials.
