Producer
Prayon Group
Belgian phosphate chemicals company with 140+ years of history (1882) and 1,400 employees. Produces purified phosphoric acids, phosphate salts (including food-grade STPP), and fluorine products at sites in Belgium, France, USA, and Switzerland. Prayon's wet-process phosphoric acid technology is used to produce over 50% of the world's merchant-grade phosphoric acid — making it the critical licensor of the key manufacturing technology behind the global phosphate supply chain. In August 2024, Prayon acquired Natural Enrichment Industries to strengthen its US footprint. Also a member of the European Sustainable Phosphorus Platform.

Did you know2024
Prayon (Belgium) produces food-grade STPP and purified phosphoric acid — but also licenses the wet-process phosphoric acid manufacturing technology used to produce over 50% of the world's merchant-grade phosphoric acid. Merchant-grade phosphoric acid (MGA) is the feedstock for phosphate fertilizers (MAP, DAP, TSP), food phosphates, and industrial phosphate chemicals. The Belgian company whose name most people have never heard controls the production technology for the primary intermediate between phosphate rock mining and global food/fertilizer production. Prayon is the IP licensor behind a majority of the world's phosphate processing infrastructure, while also being a direct producer of specialty phosphate products.
First Phosphate Corp. ↗Origin2023
Prayon S.A. was founded in 1882 in Engis, Belgium — one of the world's oldest operating phosphate chemical companies. Over 140 years, Prayon developed and refined the wet-process phosphoric acid technology that is now the global industry standard. Its technology licensing business is extraordinary in scale: the Prayon Process is used by plants accounting for more than 50% of global merchant-grade phosphoric acid production, including facilities operated by Mosaic, OCP (Morocco), and major producers in Asia and the Middle East. A 1,400-employee Belgian company effectively sets the technical standard for a critical agricultural chemical underlying global food production.
Prayon S.A. ↗Capacity2023
Prayon produces sodium monofluorophosphate (SMFP, Na2PO3F) — the active fluoride ingredient found in many of the world's most widely sold toothpastes (used by Colgate, P&G, and other major manufacturers). SMFP is a direct combination of Prayon's two core product streams: phosphate chemistry and fluoride chemistry. The same Belgian company that makes phosphate food additives (STPP for hot dogs) and licenses fertilizer production technology also supplies the compound that prevents tooth decay for hundreds of millions of people globally — with most consumers having no awareness of the shared supply chain origin.
