The ECT centre for the biological treatment of soil polluted with hydrocarbons is located at La Courneuve (93).
It is unique in France because it is the first French centre to be entirely under cover and enclosed.
This site illustrates the determination of the département of Seine-Saint-Denis to have a pathway for the decontamination, upcycling and recycling of soil from sites of the construction & public works sector.
Its excellent location (at the junction of the A1 and the A86) helps keep journeys short: 53% of the soil comes from the Seine-Saint-Denis département; 42% comes from départements adjoining Seine-Saint-Denis.

Preventing health risks
Operating in an entirely enclosed space equipped with activated carbon ventilation makes it possible to prevent biological and chemical risks.
Unloading
Soil from each site is discharged into a dedicated bay.
Sieving
The trommel screen mechanically separates fine material from coarser elements such as small stones, blocks and scrap.
Particle size 1
Large blocks more than 30 cm in diameter
Particle size 2
Items sieved out, metals, OIW (ordinary industrial waste), rubble

The treatment zone
Fine soil is transported to the zone by conveyor belt.
Analysis
Before being treated, the soil is analysed.
The treatment
Piling up in windrows makes it possible to aerate the soil and add nutrients.
New analyses
After treatment, the soil is again analysed to determine its final destination.
