![]() The project also planned to investigate the potential for efficiently and effectively extracting valuable metallurgic silicon from polluted sediments. Targeted uses for decontaminated sediment included as raw material in the infrastructure and environmental engineering sectors. It thus sought to turn a currently dangerous waste into an important resource. It sought to reduce the environmental impact of dredged material and maximise the percentage of material suitable for recycling. It sought to demonstrate the efficiency of consolidated treatment technologies coupled with innovative techniques aimed at the recycling and valorisation of dredged material.įrom a technical perspective, the project proposed an integrated cycle of actions to be applied to sediment - and associated water - immediately after dredging. ![]() The project aimed to demonstrate an integrated approach for the sustainable management of sediment dredged from ports. The polluted water is drained into wastewater systems, whilst polluted sediments are usually sent to landfill sites, incurring all the environmental risks associated with the management of dangerous waste. This material, together with the dredged water, is usually transferred into large fill-in basins. Confined Disposal Facilities (CDF) and landfills are the more common final destinations, due to limited availability of alternative techniques for treatment of pollutants.Īn assessment undertaken within the SedNet European network found that the total amount of sediment dredged in Europe is between 100 and 200 million cubic metres per year. ![]() ![]() The specific destination of dredged sediment in Italy is determined by its contamination levels as defined by national legislation. These materials then have to be disposed of appropriately. Port authorities often have to remove deposited materials to maintain the needed depths in harbour channels and basins to meet the requirements of shipping and tourism. Many European ports and harbours have a tendency to silt up over time in the face of natural environmental factors. ![]()
