Analyse du cycle de vie (ACV) d’une filière de valorisation terrestre de sédiments de dragage marins contaminés

Abstract : The dredging of the French harbors generates every year between 25 and 40 million tons of sediments, however few adapted treatment and valorization systems exist. Consequently, numerous research programs emerged such as SEDiGEST, which envisaged a scenario of backfill of the careers by treated marine sediments. The objective of this article is to assess results of the marine sediment terrestrial valorization systems in order to better identify the most impacting part of the systems. The assessment has been performed following the life cycle assessment (LCA) methodology via the GaBi 6 software, EcoInvent v2.2 databases with the characterization method ReCiPe. In the backfill scenario, the comparative study of the two treatments within the same terrestrial valorization system concluded that the addition of the stabilization step with hydraulic binders seems not to be beneficial and do not reduce the potential environmental impacts.
