Critical raw materials: discover the results of the FlashPhos project
At the final conference the next steps towards a complete industrial scale up of the technology
Redazione Open Innovation
The European Union is largely dependent on imports of white phosphorus (P4), a strategic raw material for the food and pharmaceutical industries.
To tackle this challenge, the five-year EU-funded project FlashPhos – led by the University of Stuttgart – aimed to recover at a large scale high-quality white phosphorus and other raw materials using sewage sludge as input material.
These raw materials have strategic applications for the European chemical, metal, and cement industry.
FlashPhos is the first process in the world to sustainably produce white phosphorus for the chemical industry in a full circular economy model, surpassing the quality of white phosphorus on the market today.
The FlashPhos project is now coming to a close. Partners will present the outputs and the next steps of the project towards a complete industrial scale up of the technology at final conference.
The FlashPhos “Closing event: Results, Impact & Way” will be held in Loeben, Austria on the 21 st April, 9:00-17:00.
The final conference will bring together partners, stakeholders, and experts from industry, research, and policy along the phosphorus value chain.
The event is relevant for all stakeholders active in:
- Wastewater and sewage sludge treatment
- Thermal conversion and drying technologies
- Cement substitutes and construction applications
- Waste management, bioeconomy, and circular economy
- Critical raw materials in Europe
- Phosphorus applications in sectors from pharmaceuticals to electronics.
A highlight of the programme will be a site visit to the pilot plant at ARP, a partner of the project, offering a first-hand look at the project in practice: it’s the first industrial pilot plant for producing secondary elemental phosphorus out of sewage sludge.
