International audience ; Management of dredged sediments is an issue for many European countries. At the same time, there is a concomitant increase in demand for construction materials with regional to sub-regional deficits in suitable sources to supply the market. The use of dredged marine sediments in civil engineering applications could provide potential solutions for both issues, however existing EU legislation for handling dredged material is complex and from a policy perspective, dredged material is dealt at the intersection of EU Water, EU Waste and EU Marine Strategy Framework Directives. Procedures and contaminant thresholds to authorize relocation of these sediments at sea or in land vary considerably from one country to the other and there are no harmonized regulations at EU level. In this context, the CEAMaS project aims to bring about a major improvement regarding the widespread uptake of practices involving the beneficial reuse of dredged marine sediments. This will be accomplished by providing new and enhanced tools, methods, services and detailed knowledge on established and innovative civil engineering applications. Key outputs will be a common European reuse methodology applicable to all ports and sediments backed by a European Resource Centre which will provide the focal point for knowledge capitalization and raising awareness of sediment reuse options.

International audience ; The SURICATES project is a research initiative funded by the European Union regional funds (INTERREG NWE), aimed at increasing the reuse of dredged sediments.The current European practice favours relocation at sea without beneficial uses(more than 99%), unless the sediment is highly contaminated. In many countries, dredged sediments are considered as waste, increasing thus waste productionby 200 Mm3/y (80 Mtdry weight). The waste statushampers sustainable fluvial and marine transport and prevents sediment reuse as an alternative to minerals extraction for civil engineering.Climate change, erosion and flood risk increase require greater mitigation measures(strengtheningor regeneration of harbour/river banks,beach nourishment),consuming high volumes of natural resources.Previous research projects (CEAMaS, PRISMA, SETARMS) highlighted various reuse alternatives and investigated them at the laboratory scale, with specific attention for environmental, economic and social aspects.This is not enough to convince sediment managers of the feasibility of reuse optionsand move towards circular economy options.
