• 6 treatment centres
  • 227.000 tonnes of soil in 2016
  • 98.000 tonnes of sediments in 2016

In common with other parts of Jan De Nul Group, the Environment Division Envisan also goes for an integrated approach, from design to execution. Sediments and soils coming from dredging and earthworks are transported to own treatment centres for treatment or decontamination. Today, it has six such centres available. 

Envisan Centres

Manager Kristof Nachtergaele describes the operation and development of our treatment centres: “Dredging and excavation works often result in a big amount of sediments or soil. When we are working in the Benelux and France, the bulk of these soils are conveyed to the most suited treatment centre of our own. The first and foremost criterion here is location: the closer the centre, the less transport and thus the cheaper and more efficient it will be for our client. Obviously, we also consider the treatment that is needed, because some centres solely process non-contaminated soils whereas other ones have been specifically equipped for this.”

"Today the number of Envisan centres has doubled"

“Compared to three years ago, the number of Envisan centres has doubled. We notice that the demand for integrated projects increases and treatment of sediments and soils is an important activity within the process chain.

The following step that we must take is encouraging the mutual cooperation between our centres. But that will not suffice to meet demand. We also have very concrete plans to expand our six existing centres with another centre in Northern France. Our target is to open the new centre in 2019.
