Our Concept

The award-winning FlashPhos process is a high temperature fast reacting (flash) entrained flow gasification of sewage sludge and other phosphate-containing waste streams such as meat-and-bone meal. The inorganic waste components are melted or evaporated and are then separated in a refiner reactor to produce recycled P4 as the main product. Other output materials of the process are a climate-friendly alternative cement raw material, an iron alloy and a heavy metal concentrate as valuable outputs for the metal industry. The organic components serve as fuel for the gasification, in which they are converted into heat and a combustible gas. This gas and excess heat can be used in cement plants to substitute fossil fuels. Consequently, several valuable raw materials will be generated by the innovative and cost-efficient FlashPhos process with practically no emissions or waste.

During the four-year innovation action, the industrial FlashPhos process will be demonstrated in a pilot plant with up to 250 kg/h sewage sludge throughput. The first full-scale FlashPhos pilot plant in Europe will be built by 2025 and industrial scale white phosphorus production will start together with an industrial consortium, expecting market introduction by 2028.

💡 #EUProject @FlashPhos aims to close gaps in the #circulareconomy by demonstrating a real #zerowaste process, returning all output mass & energy flows to the industrial cycle, thus contributing to #resourceefficiency, #energysavings & #wastereduction.


🎞️Treasure hunt in #sewagesludge - can we turn sewage sludge into gold? Yes, we can! #EUProject @FlashPhos coordinator @MatthiasRapf explains in @ARTEde documentary 🎥 how this is done (German, French subtitles available, start: 19:20) #zerowaste

📢📅 Lukas Pohl from @FlashPhos partner @Uni_Stuttgart is participating in the 4th #Bioeconomy Congress BW next week and presenting a poster on #FlashPhos on September 27.

Raw materials are essential for our daily lives.

It is important to ensure the security and sustainability of their supply.

The European Critical Raw Materials Act will:

☑️ Identify strategic projects along the supply chain
☑️ Build strategic reserves for our Union


💡 White #phosphorus is a strategically important substance irreplaceable for key industries like food, pharmaceuticals & electronics.

@FlashPhos will produce #highquality white phosphorus & other #rawmaterials using #sewagesludge as input material 👉 http://buff.ly/3pbCToW
