Abstract
The sediments used in the Subsed project were partially decontaminated in a previous European project (AGRIPORT Agricultural Reuse of Polluted dredged Sediments, No. ECO/08/239065/S12.532262), using plants (phyto-treatment) and an organic amendment (such as compost) at pilot scale level. In the Subsed project, with the aim to make the sediment a suitable substrate for plant growth, a landfarming process has been planned as a post-treatment phase. The landfarming was carried out in the demonstration basin of the previous AGRIPORT project (covered with a geo-membrane to avoid the eventual contamination of soil during the process), in Livorno port (43°33'31.78"N, 10°18'29.32"E), allowing to reduce the transportation costs. 11 The three sites, as requested by authority, were prepared to protect the areas and to prevent the sediment from contaminating the environmental matrices, avoiding dispersions and runoff. Following the approval of the works carried out, the authorization to deliver the sediments was finally granted. In two sites the sediments arrived on 01/06/2020 and in the last one on 08/06/2020.
