Building a sustainable future together
For more than 30 years we've been working toward a cleaner environment. From our base in Gentbrugge with branches in Grobbendonk and Roncq (France) more than 200 professionals work daily on solutions for water, air and energy.
Three entities, one vision. Trevi nv is the driving force: a multidisciplinary team that guides companies from A to Z toward sustainable solutions. BiogasTec nv converts organic streams into renewable energy through its own biogas plants. Trevion delivers that energy directly as 100% green electricity.
Together they form a single point of contact for any environmental challenge — from design to realization, from advice to energy supply.
