The project took place in Denmark, in the city of Alleröd. The site is located in an industrial area, on the grounds of a power station (DONG Energie), under a high voltage transformer. Peak concentrations of chlorinated solvents reached up to 0.38 mg / kg dm, on an area of 36 m2 with a volume of 288 m3. Oil was also detected, with a concentration level up to 15.000mg / kg. The burners were powered by propane. The work was done...
The site is located at H&S AVIATION AIRPORT SERVICE ROAD HILSEA PORTSMOUTH PO3 5PJ, on a former aviation site. The project is made on a 243m² heating zone (6m depth) with 7 gas burners and 14 heating pipes. Soil was impacted by Chlorinated Solvents and Kerosene. The figure shows the evolution of recovered contaminants through out treatment time. The figure shows the temperature’s curve through out treatment process. Contaminants’ concentration after treatment was of <1mg/kg DM. All remediation objectives were achieved. Contaminants VOCL Max....
DEEP GREEN’s regroupment and treatment center at Sotteville-Lès-Rouen (76) treated more than 13,000 tons of polluted soils coming from Gosnay, one of Charbonnages de France’s site. Afterwards, the treated soils were transported to Gosnay to be used as fill. The project was done with the DRAGON 35 unit, according to the law prescriptions (of the “Arrêté Préfectoral”). The unit was equipped with continuous emissions monitoring systems. The soils to be treated held PAH average concentration of 6000 mg/kg and TPH average concentrations...
The Equipment and Transport Administration of the Brussels Region, the project manager, was faced with TPH contamination at the DELTA site. This site comprises an underground station, an underground metro depot and a bus depot. Twelve single-wall metal tanks were buried on the site and showed signs of leakage. Mourik, the main contractor, carried out 6 meter deep excavations and removed the tanks. Further excavations were prohibited because of questions of the stability of the building. Deep Green was then chosen...
The clean-up site was formerly used by Aceralia (Steel plant) in Avilès and the soil to treat came from the various locations within the steel factory that generated contaminated soil. The clean-up was funded by the Infoinvest (Spanish Governmental agency in charge of industrial redevelopment of contaminated sites). The soil was already excavated by the client. Deep Green has contracted the sieving and the thermal desorption part of the contract for the PCB and PAH contaminated soil. The project started with...

Thermal desorption of 14,000 tons of TPH contaminated soil by means of a mobile unit. The contaminated materials came from various areas within the Peugeot‐Mulhouse car construction site. Pollution was mainly TPH (diesel). The project was done with a DRAGON 15‐2 mobile unit, set as a cold plant. Stack tests were regularly performed and were supervised by the DRIRE and an external independent consultant working directly for the client (Peugeot). The clean‐up goals were to reduce the TPH concentrations from 500‐12,700 ppm...

Thermal desorption of 1100 Ton of contaminated soil coming from the Mont Saint-Martin Gaswork site by means of a mobile unit located in Homécourt (France). The site was a previous cokeswork, which will be reaffected into small business area. The cokesworks were owned and operated by USINOR (Group ARCELOR), and the company decided to clean-up the site before reusing it through the local community. The contaminated soils held average PAH concentrations in excess of 12,000 ppm (with max concentrations up...
Thermal desorption of 21,000 tons of contaminated soil coming from the Homecourt gaswork site by means of a mobile unit. The site was a previous cokeswork, which will be reaffected into small business area. The cokesworks were owned and operated by USINOR (Group ARCELOR), and the company decided to clean-up the site before reusing it through the local community. The contaminated soils held PAH concentrations in excess of 9,000 ppm with average concentrations at 3,200 ppm. The project was done with...
