The 5th meeting of the SedNet WG “Sediments in Circular Economy” (WGCE5) was held – due to COVID-19 – as a videoconference on November 5th, 2020. It was attended by 43 participants from 11 countries.

The program began by 6 technical presentations, followed by lively Q/A sessions:

  • Pilot projects for beneficial use: the Port of Rotterdam SURICATES sediment relocation project (Deltares and Port of Rotterdam – Arjan Wijdeveld and Marco Wensveen)
  • Pilot projects for beneficial use: Bowling SURICATES sediment land restoration, tidal and flood protection project (Scottish Canals and Strathclyde University – Keith Torrance and Richard Lord)
  • Dehydration equipment as a support for beneficial use of dredged sediments (IXSANE, Tristan Debuigne and Mohammed Boumahdi)
  • Mineral processing techniques as a support for beneficial use of sediments (CTP, Mathieu Henry)
  • The impact of gas on sediment rheology (Julia Gebert, Florian Zander, TU Delft)
  • Sediments (contaminated) behind dams and river restoration – mass stabilization processing, and beneficial use. Case Study: Gorge Dam, Ohio (Eric Stern, Montclair State U. and Tipping Point Resources Group and Robert Miskewitz, Rutgers U., USA)

Then followed two updates on Emerging compounds and sediment management – contaminants under recent focus, PFAS and microplastics.

A work session was held on the White paper on Circular Economy and Beneficial Use of Sediments currently elaborated by the WG.

The current Green Deal call for research proposals was discussed and gave opportunities for SedNet members to network and express interest in joining consortia.

An update was provided on the 2021 SedNet conference in Lille, France, and its Circular Economy session. The call for papers was reminded.

A detailed meeting report will be disseminated to the members of the SedNet WG “Sediments in Circular Economy”.
