This certificate has been granted for the physicochemical washing plant for contaminated soils at Envisan’s site in the port of Liège.

The washing plant reflects the company’s motto: ‘Circular solutions for a better planet’.

Since 2021, Envisan has been operating a plant for washing contaminated soils in the port of Liège. The result is washed sand and gravel that is offered to the local construction market.

Also, this installation was the first of its kind for the Walloon market, said Jan De Nul.

An Smet, Director of Envisan at Jan De Nul Group, said: “Thanks to its trimodal location, the port of Liège is an ideal operating base for us. Contaminated soil can be delivered by road, water or train. We focus primarily on inland shipping to keep our CO2 footprint low there as well. We are particularly proud that this ‘End of Waste’ certificate recognises our efforts to fully embrace circular solutions.”

The physicochemical plant has a capacity to produce in two days an average of 800 tonnes of washed sand and gravel from 1,000 tonnes of heavily contaminated soil.
