Polluted soils


Soils contaminated by biodegradable organic compounds (diesel, fuel, kerosene, crude oil, certain heavy petroleum fractions, certain types of polycyclic aromatic hydrocarbon …).


  • Pre-processing

Particle separation of exogenous materials (rocks…) contained in the soil (screener).

  • Decontamination

Soil excavation and decontamination using the Biocentre © technology, based on micro-organisms naturally degrading the pollutants – an efficient way to manage the environment.

  • Material recovery

Recovery through heap revegetation or backfilling off-site.
When recovery is not possible because of the nature and concentration of the pollutants, the latter are removed to landfill in specific areas in a hazardous waste disposal facility.

Key facts

1 million tonnes of contaminated soil treated and recovered every year

11 polluted soil treatment centres


  • TERNAY: Recovering contaminated soil
    Sita - Ternay valorisation des terres polluées

    The first facility of its kind in the Rhône-Alpes region (France), this new centre completes the network of five other units in France accredited by SITA under the name Neoter®. Thanks to Neoter®, the polluted soil generated by construction sites and client industrial sites are sorted and pre-treated in order to increase their recovery capacity. In Ternay, the goal is to recover half of the soil treated in situ. In close proximity to the Rhône River with a dock directly accessible, the site of Ternay is ideal for the use of river transport. SITA FD’s goal is to transport half of the global tonnage using maritime means, therefore reducing CO2 emissions and the ecological footprint involved in processing polluted soils and sediments.
