10 local branch offices
6 biological treatment platforms and biocentres for recycling contaminated soils
Various techniques used:
- Soil decontamination: biological treatments (bioremediation, soil biopile or biomound), thermal, physicochemical (oxidation, reduction, stabilisation, washing, etc.) or physical (venting, containment, etc.)
- Water decontamination: pumping/skimming, filtration, sparging, stripping, bioremediation
- Water, sludge and sediment treatment: oxidation, chemical reduction, electro-flocculation, biological treatments
Focus
AN INNOVATIVE BIOREMEDIATION SOLUTION FOR CHLORINE COMPOUNDS
Our subsidiary OGD uses an innovative technique to treat chlorinated solvents in groundwater in situ: reducing dechlorination, or anaerobic biological treatment. The principle is to stimulate the activity of micro-organisms present in soil and groundwater, in order to accelerate natural breakdown of solvents. Less costly, this dynamic and permanent system can be implemented without stopping operation of the site treated and has a limited impact on the environment.
GRAND PARIS EXPRESS, A SITE WITH EVERY CHALLENGE
As part of a partnership agreement with Société du Grand Paris, our biocentres were contracted to receive and recycle part of the spoil generated during construction work on the new metro for the Grand Paris Express project. A total of 45,000 tonnes! By means of a best practices charter, which we were one of the first 31 companies to sign, we are committed to recycling this spoil responsibly. Soil contaminated with organic matter (hydrocarbons, diesel fuel, oils, etc.) will be treated using processes that speed up the natural breakdown process for these pollutants. By connecting our biocentres to the river network and using barges to transport spoil, we will also contribute to limiting greenhouse gas emissions during the work.
