2. - Oberoende FoU-institut
- Kompetenscentrum för geoteknik och miljögeoteknik
- Geoteknisk forskning och rådgivning samt myndighetsansvar i
ras-, skred- och stranderosionsfrågor.
- Nära samspel mellan forskning, rådgivning och information
inom mark-användning och byggande.
- Samverkar med den geotekniska marknaden – myndigheter,
universitet, konsulter och entreprenörer.
- Arbetar mycket med klimatanpassningsfrågor.

3. Background
• To develop BSR (Baltic Sea Region) in a sustainable way contributing to an
extended interaction and co-operation sea transport is a key issue
• Dredging of fairways and ports have to be made and several million m3
of sediments have to be dredged in the coming years
• A considerable part of the dredged sediments is contaminated with non-
organic and/or organic contaminants (e.g. heavy metals, dioxins, PCBs,
PAHs, TBT)
• Dump of sediments at the sea normally not allowed
• Land disposal most expensive
• Initial projects show large potential for innovations regarding beneficial use
of treated contaminated sediments and knowledge transfer to get a BSR
approach (e.g. the stabilisation/solidification method)

5. Outcomes
• Guideline for management of contaminated sediments
including handling alternatives
• Tool-box of treatment technologies, tools for assessment of
sustainablity, decision support tools
• Field tests to validate, demonstrate and communicate
emerging treatment methods under various conditions
• Permanent network for the management of contaminated
sediments of BSR
