Belgium-based Prayon Group is one of the world leaders in phosphate creativity, with more than a century of industrial experience. Prayon Group is owned jointly by the Office Chérifien des Phosphates (OCP) and the Wallonia Regional Investment Company (SRIW). Prayon manufactures purified phosphoric acids, phosphate salts and fluorine products at sites in Belgium, France and in the United States and serves a global customer base. Prayon products are used in food (including baked goods, meat, processed cheese, fish and seafood, cereals, fruit and vegetables), drinks, pharmaceutical products (including toothpaste, oral hygiene products and excipients) and a broad range of industrial applications (e.g. paper, ceramics, glass, metal, and so on). The Prayon wet processes for phosphoric acid production and associated equipment (e.g. Prayon Filters) are marketed throughout and are used to produce over 50% of the world’s merchant grade phosphoric acid. In order to diversify raw materials, Prayon has engaged some 20 different projects over the last two years, mostly business-to-business (confidential with concerned customer), covering food industry by-products, biomass energy and other ashes and spent reagents (on average 8 000 t/y of phosphoric acids recycled since 2000) see SCOPE Newsletter n°123.
