Thermal desorption of 700 tons of contaminated soil coming from the Rombas gaswork site by means of a mobile unit located in Homécourt (France). The site was a previous cokes work, which will be reaffected into a small business area. The cokes works 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 14,000 ppm with average concentrations at 7,800 ppm.

The project was done with the mobile DRAGON 35 unit, in a hot plant set-up, located in Homécourt (France). Stack tests were regularly performed and were supervised by the DRIRE and an external independent consultant working directly for the client (Arcelor). The unit was equipped with Continuous Emissions Monitoring systems.

Clean-up targets for clean soil were set at 20 ppm total PAH (16 EPA). All clean soils were under the clean-up target after treatment.

This project was designed and executed by the current Haemers Technologies team, when they worked within the legal entity L&C SA (formerly Deep Green SA), which belongs to the Haemers Technologies group.
