Waste Treatment and Valorisation

Worldwide, public authorities and companies attach ever increasing importance to the eco-friendly handling of waste substances. Not only from ecological considerations but also from the economic perspective that waste can quite often still be turned into a valuable raw material or fuel.

Envisan offers sustainable and customer-oriented solutions and services with regard to the reuse, valorisation, treatment and safe storage of specific waste flows. The focus is on the high-quality execution of multidisciplinary environmental remediation projects for which we can turn to the engineering and innovation capacities of our mother company Jan De Nul Group.
