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)


SGI Lead Partner

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 communicateemerging treatment methods under various conditions

• Permanent network for the management of contaminatedsediments of BSR
