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 to 18,000 ppm).

The project was done with the mobile DRAGON 35 unit, in a hot plant set-up. 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.
