Promoting the beneficial use of dredged sediments for sustainable applications instead of being disposed of, at sea or on land. Dredged sediments are one of the largest potential waste flows. Sediments are part of our potential mineral resources. Sediments are thus eligible for circular economy thinking. Minerals and aggregates for industry, potential for land improvement - landscaping, brownfields, coastal nourishment, energy crops, land uplift Economics of direct costs vs. indirect benefits.Regulatory issues: Waste status, relocation, product status for reuse. Promoting acceptability, lessons from case studies. Knowledge gaps or bottlenecks for beneficial use development. No deliberate extraction. Focus on sustainable uses (navigation, flood or coastline protection, environmental remediation).
