SURICATES: demonstration through pilots of sediment reuse for coastal defence or climate change mitigation

Abstract

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.
