Our activities

With a history that dates back to 1919, Tessenderlo Group has evolved over recent years from a chemical company into a diversified industrial group that focuses on agriculture, valorizing bio-residuals, energy, and providing industrial solutions with a focus on water.

With more than 4,800 people working at over one hundred locations across the globe, Tessenderlo Group is a leader in most of its markets. We primarily serve customers in agriculture, food, industry, construction and health and consumer goods end markets.
