GREEN SITE Project “Remediation of polluted sediments in Porto Marghera using Supercritical Fluids”

Abstract

Green Site Project aims at demonstrating the effectiveness of innovative technology for the reclamation of sediments coming from dredging. The technology, to be demonstrated, involves the use of fluids at a supercritical state for the extraction of organic pollutants from the sediment (1^st phase) and the use of supercritical water for the oxidation (2^nd phase) of the hydrocarbons and organic compounds extracted before. At the end of the process, a clean sediment and some clean water will be obtained.

Project targets consist into obtaining over 90% abatement of organic solvents in the sediment and over 95% abatement of washing liquor, without using solvents.
