The first economically viable process for phosphate recycling

Project description

Innovative technology for phosphate recycling

Phosphorus (P) is a critical raw material in the EU and a vital constituent in fertilisers. The EU imports 90 % of what it consumes and 90 % of what is used is irreversibly lost. No technology can upcycle sewage sludge ash (SSA) for direct use by manufacturers of phosphate-based flame retardants and fertilisers, and competing solutions are costly. They all use water as a solvent and are characterised by high energy consumption. The EU-funded SusPhos project proposes a near-zero-waste process solution that upcycles P-rich waste like SSA or struvite into phosphates, iron and magnesium salts, and silica mixtures. These high-quality, pathogen-free compounds are suitable for formulating fertilisers and flame retardants. The solution uses only waste heat, allowing competitive costs.

Objective

In the EU, phosphorus (P) is listed as a critical raw material. It is essential for life and there is no known substitute. P is a vital constituent in fertilisers; the EU's agricultural need is 3.9 Mt/yr. We import 90% of what we consume, and 90% of what we use is irreversibly lost. The SusPhos solution upcycles P-rich waste like Sewage Sludge Ash (SSA) or struvite into phosphates, iron & magnesium salts, and silica mixtures. Our high-quality, pathogen-free compounds are suitable for formulating fertilisers and phosphate-based flame retardants (FR). Reaction by-products are fine-chemicals in their own right, making our technology a near-zero waste process. Currently, there is no technology except ours that can upcycle SSA for direct use by FR or fertiliser manufacturers. Competing solutions for P recycling are cost-prohibitive. They all use water as a solvent, which means high energy requirements for solvent evaporation. Our patented solution uses merely waste heat, which allows us to price our phosphates on the same level as if they were derived from mined phosphate rock.

We will create an independent EU supply of recycled P, reducing the EU’s dependence on supply and price volatility. By 2026, we project revenues of €33m and a >20% displacement of conventionally produced phosphates. Our circular P will eliminate CO2 from rock phosphate transport and reduce pollution caused by mining. Our “urban mines” (SusPhos plants) will create hundreds of jobs across the EU, and at SusPhos, we are striving to strengthen female leadership and inspire women to choose to conduct their higher education and build carriers in chemical engineering and raw materials (currently very male-dominated sectors). With the support of Women TechEU, we aim to upgrade our rollout plan and sharpen our business development skills so that we can grow large enough to become a leading technology provider for circular P, and to become and influential player in deep-tech innovation ecosystem.
