At Prayon, we set the tone in the phosphate world
Prayon solutions are best-in-class with:
Headquartered in Belgium, the Prayon Group has two shareholders: OCP and the Wallonia Regional Investment Company (SRIW). With approximately 1.200 employees, we operate production sites in Belgium, France and the United States and have 2 R&D sites in Belgium as well as our testing and validation facility Technophos in Bulgaria.
Phosphorus chemistry is vital to our daily lives and is at the core of everything we do at Prayon.
Since its creation, technology is in the DNA of Prayon. Together, as a team of talented, diverse and engaged collaborators, we aim to further leverage technology to make the difference in people’s lives, communities and our planet by:
Because we want to win together, we think far, we aim high, push boundaries, and keep our promises to deliver our customers.
We are committed to designing efficient and sustainable processes to protect resources. Our wet process for phosphoric acid production uses up to 7 times less CO2 than the thermal process.
We are pioneers in the art of designing production processes in line with circularity, achieving excellent yields with our raw materials as well as valorizing our by-products.
Our ultimate aim: closing the loop.
Working in zinc and phosphorus, present in Belgium, France, Bulgaria and the United States, Prayon has been innovating and leading the world of phosphorous chemistry since 1882.
The story of the company began with the S.A. Métallurgique de Prayon, which went on to grow its activities in food and industrial applications, horticulture, construction and pharmaceutical products. Read on to learn more about the Prayon Group and how it made a difference. Discover our major milestones.
The Société Anonyme Métallurgique de Prayon was created on May 15, 1882, in Trooz, Belgium. It initially took over the Nouvelle Montagne factory and later the Engis site. With its 200 workers, SA Prayon very quickly became the leading producer of zinc in Belgium.
In 1888, Prayon established its first sulphuric acid production unit, using the so-called “lead chamber” process, which was the benchmark method until the arrival of more modern materials.
New premises were needed to keep up with the growth of the company. Prayon chose Puurs (Antwerp, Belgium) to set up its first industrial activities away from the head office.
Prayon developed a continuous production process for phosphoric acid, thanks to the Tilting Pan Filter design.
Prayon bought shares in the Société des Produits Chimiques et Métallurgiques de Rupel in Puurs.
1959 marked a turning point in Prayon’s fertiliser and phosphoric acid activities. With a new granulation facility, the company was able to offer a wider product portfolio. One year later, a 25t/day bi-ammonium phosphate production unit was launched. It allowed for new opportunities outside of the fertiliser sector.
Just before celebrating its 100th birthday, the Société Anonyme Métallurgique de Prayon officially became the Société Chimique Prayon-Rupel (“Prayon”), the parent company of the current group. Its main activities are phosphate chemistry (phosphoric acid and derived salts) and specialised inorganic chemistry (zinc oxide, sodium hydrosulfite, fluorinated salts and anti-corrosion pigments).
Silox, a company that produces active zinc oxide, is created.
Prayon took part in the creation of Europhos, whose French production unit (in Les Roches de Condrieu, Lyon), became the Group’s third production centre in Europe, after Engis and Puurs. The company would later be integrated into Prayon s.a. in 2003.
The Group participated in the creation of Emaphos I (Morocco), a phosphoric acid purification company active, in partnership with its shareholder O.C.P. (Office Chérifien des Phosphates), the world’s leading producer of phosphoric acid and owner of the largest phosphate ore reserves in the world.
Prayon Inc. was created and phosphate salt production units in Augusta (Georgia, USA) are acquired.
Europhos was integrated into Prayon s.a.
We opened our sales office in India.
Prayon signed a cooperation agreement with ALMIN which allowed it to expand its range of products, and refractory products.
Prayon opened a new sulphuric acid production unit at the Engis site.
The Group signed an agreement with Pulead (China), a leading producer of cathode materials, to create a joint venture for the production and sale of lithium iron phosphate (LFP) licensed by LiFePO4+C Licensing LLC (*).
