Prayon S.A.

Prayon S.A.

Prayon is a world leader in the phosphate sector. Our Group manufactures an extensive range of phosphate and fluorine products that are used in food applications, industrial applications, fertilizers and other applications such as pharmaceuticals. Prayon has two joint core shareholders -Office Chérifien des Phosphates (OCP) and the Wallonia Regional Investment Company (SRIW) - as well as 20 companies operating mainly in the phosphate chemicals industry. Via our subsidiary SILOX, we also manufacture specialty inorganic chemicals (zinc oxide, sodium hydrosulfite, anticorrosion pigments, etc.). Our growth is the result not only of the reinforcement of our traditional product structures and lines, but also of a policy of product and market diversification undertaken in partnerships with reputed chemical companies, in the form of industrial and/or commercial joint ventures.

Our commitment

Supported by my dedicated management team, I am committed to ensuring that the Group fulfils its mission and to guiding it in achieving its vision whilst remaining true to its core values.

Safety is a top priority. Every day we work to make our sites safer and our facilities more secure, to enhance food safety and to make sure that our products are used safely. Safeguarding human health and the environment are also core principles.

We want to become a leading player in niche markets such as food additives, horticulture and industrial applications offering a high level of added value. We also want to further consolidate our position as the world leader in phosphoric acid technology.

We are keen to cement the company’s long-term future via a strategy of excellence in the form of our six strategic priorities, and profitability which will generate added value for staff and shareholders alike.

We are careful to listen to both customers and the market and in this context we supply top-quality services and products and provide the very best application support.

Against the backdrop of a highly competitive market, we must continually seek to innovate. We encourage our staff to be creative and to enhance their skills and expertise through appropriate training. Recognising performance and acknowledging achievement is a core value for us in terms of motivating and rewarding our staff.

The Group’s Management System plays a crucial role in helping us to achieve our goal of improving risk management. Implementing and monitoring this system rigorously across all the Prayon Group’s units is vital in order for us to roll out action plans the results of which can be verified and recognised.

As far as Prayon is concerned, honouring this Commitment and complying with all relevant legislation, standards, agreements and contracts with partners and customers is a core requirement and one we are more than willing to fulfil to ensure our long-term future.
