Sustainable Environmental Treatment and Reuse of Marine Sediment

The different workpackages

Dredging, absolutely necessary to maintain economic Ports activity

90-95% of sediments are immersible in areas, subjected to official authorization. However, legislation is becoming increasingly restrictive. On the other hand, filing spaces are becoming scarce and delivery in storage remote places has significant costs for port authorities.

Anticipating future legislation and capitalizing on existing recycling options for 5 to 10% of sediments stored on land, the multidisciplinary Franco-British partnership is working to find recycling options for each type of sediment that are economically viable .

Thus, the characterization - or study the composition of these sediments, in order to establish the typology is an essential step. The sediment types will define the most suitable recycling and / or reuse options .

Workpackage 1 : Overview of the current dredging operations in the Channel area

Led by APLM

Various studies will be conducted on:

The Overview of the current dredging operations in the Channel,
Characterization of Disposal Sites
Comparison of European regulations, French and English
The possibilities for mutualizing the dredging resources

Workpackage 2 : Characterization of the sediments

Coordinator: University of Brighton
The University of Brighton will coordinate all scientific research relating to the characterization, including geochemical and geotechnical characterization of the sediments  collected from the sampled harbours.

Worrkpackage 3 : Re-use of the sediments

Coordinator: Ecole Supérieure d'Ingénieurs des Travaux de la Construction of Caen (High School of Engineering in Construction Works of Caen)

This axis will develop innovating techniques that can be applied to civil engineering. The company Eurovia will use 6 of the samples to create a test road portion 20m5m to test the durability of sediment layers in the sub-road.
