Objective : Study the feasability of a regional sector of treatment and valuation of contaminated river sediments, and to define the legal regime.

Scientific Committee :


Ixsane introduced and coordinates a project of Research & Develoment concerning the feasibility study of treatment and valuation of contaminated river sediments. The project is based on two complementary processes : at first the wash and the recovery of the most unrefined part of sediments for a direct re-use in public works and secondly the inerting and the valuation of the finest and most polluted part.

The experiment plan has 6 steps :

  • Sampling of sediments stocked on a deposit field and also of some underwater sediments for treatment, chemical and grading analysis trials
  • Trials of sediments cleaning
  • Trials of remnants treatment
  • Reusing channels research
  • Legal Study concerning the treatment of polluted sediments reusing
  • Socio-economic study for the creation of an industrial channel
