WOS / Sites


WOS specialises in treatment of liquid and solid hydrocarbon waste, from which it produces petroleum fractions such as base oil, heating gas oil, heavy fuel oil, bitumen etc.

The WOS industrial activities prolong the lifetime of the substances and contribute to the environmental performance of other sectors of industry.

WOS Hautrage S.A. is located in Wallonia, near Mons.

WOS Genk N.V. for its part is located in Flanders. Both these companies are close to the Belgian border and have excellent connections to the international road, rail and inland waterway networks.

A team of more than 85 specialists and a treatment capacity of 150,000 tonnes annually are at the service of recycling and regeneration of hydrocarbon waste and production of petroleum substances.

The quality, health & safety and environmental policies are confirmed by ISO 9001 and ISO 14001 certification for both WOS Hautrage and WOS Genk, and will shortly be completed by OHSAS 18001 health & safety certification.
