Project LIFE12 ENV/IT/000652 POLLUTED SEDIMENTS : A PROBLEM (CLEANSED SOLUTION) OBJECTIVE: A suatainable management for polluted dredged river sediments. Treatment of polluted sediments to obtaining a valuable material. VALORIZATIONa) Plant nursing: decontaminated sediments (after treatment) could be used as sustrate for plants; b) Sediments could be used for road construction. Sustainable Development (CIRCULAR ECONOMY) We should know:- Quantitative and qualititative sediment characteristics- Decontaminaned technology for polluted sediments- Final use for treated sediments.

Project LIFE12 ENV/IT/000652 CONCLUSIONS (Ourexperiment) (Soil + TreatedSediment) ON SOILS 1)“Soil +Treated Sediment”:this mixture showed a positive effect on some soil parameters (total organic carbon, soluble organic carbon, cation exchange capacity, soil total nitrogen,…). 2) Electric conductivity, Ca and S total and soluble, increased when treated sediment was used as amendment (maybe due to Ca, Mg,. Sulphates). 3) Fe and P soluble were increased on control soil 4) No change for some soil heavy metals by the use of treated sediments; it is depending of the dose used (particularly for Zn e Cd). 5) No change for microbial activity was noted by the use of treated sediment 6) The use of treated sediment did not affect the phytotoxicity 7) Physical parameters: some positive effect has been observed.
Project LIFE12 ENV/IT/000652 CONCLUSIONS (Ourexperiment) (Soil + TreatedSediment) ON PLANTS 1)“Soil +Treated Sediment”: a positive effect on macro and micronutrients on some plant species was observed. 2) Plant species is the main factor for this study. 3) No change on plant heavy metals by the use of treated sediments was observed 4) pH value (basic) is positive to avoid some risks (e.g., heavy metals accumulation on plants).
