Performance Chemicals

Who are we?

The Performance Chemicals Business Unit produces value added chemicals that are used by a broad spectrum of industries, such as water treatment, chemical, oil & gas, refinery, steel, food, de-icing, and fertilizers.

The production processes of Performance Chemicals are built in a sustainable way and they enable the conversion or recycling of industrial by-products (for example, from the steel industry) into attractive new products for water treatment. Performance Chemicals has four production sites and these are located in Loos (France), Tessenderlo and Ham (Belgium), and Rekingen (Switzerland). The production sites are centrally located in areas where the demand is highest.

In Loos, we have a state-of-the-art membrane electrolysis unit that is the beating heart of our site. Through the intermediates received from our electrolysis unit, we are able to produce a wide range of products. Our principal products are ferric chloride, a coagulant that is used in industrial and municipal markets for the treatment of wastewater or the purification of drinking water, caustic soda and sodium hypochlorite, which are used for disinfection and household cleaning, and hydrochloric acid. Our Business Unit supplies some of the largest metropolitan areas in Western Europe, including Paris, Amsterdam, Geneva, Lausanne, and Brussels, with the chemicals required to treat their wastewater.

At our Tessenderlo site, we also produce ferric chloride and hydrochloric acid, in addition to the production of sodium sulfide and sodium hydrogen sulfide. These products are used in the tanning and mining industry and as precipitating agents for metals in waste treatment.

The manufacturing of CaCl2 takes place in Ham. Calcium chloride is used in the food processing industry, in industrial applications, and for dust control and as a de-icing agent. Our production of sulfuric acid also takes place in Ham and this is used in the manufacturing of fertilizers, chemicals, and pigments. Ham is also an important site for the production of hydrochloric acid.

Meanwhile, our site in Rekingen produces iron salts, which are key ingredients in pharmaceutical drugs both for the treatment of iron deficiency anemia (IDA) and specific veterinary applications.
