Handling alternativesPrincipal fates of
contaminated sediments
Scenario 1 –Beneficial use
Using for ex stabilization of sediments and
beneficial use asmaterial instructures.
No landfilling.
Scenario 2 –Landfill
Sediments arelandfilled.
New materialsneeded forstructures.
Scenario 3 –Sea disposalSediments aredisposed of at
sea. New materials
needed for structures.
No landfilling
Resources:Materials
and energy
Scenario 4 –Fill
Confinedfill behind anEmbankment.New materialneeded forstructures
No landfilling
Scenario 5 –In-situ
Capping or otherprotectiveactions.
New materialsneeded forstructures.
No landfilling.
6- Noaction
Pollution ofSeas.
New materialsneeded forstructures.
Given: Continousconstruction activitiesin the society

Green RemediationNov 9-10, 2009
STABCONSTABCON Proposed indicatorsLevel 1 Level 2 Level 3 Commentary
Investment cost including project risk
The cost related to the developer/project owner Economiy aspects
National economy Economy in a broader context
Local protection areas
Impact on nearby environment, including acceptance/worry concering recreation, noise, accidents etc.
Socio-cultural aspects
Regional and national protection areas
Impact on national interests such as culture, power supply, fishing etc, for ex Natura 2000
Risk for contamination of nearby land
Toxic impact on water and land areas
Risk for toxic effect on organisms
Toxic impact on vegetation and organisms
Enviromental impact on a site specific scale
Risk for health effects Toxic impact on humans
Use of finite resources Use of materials and fossil fuels
Use of land and water areas
Enabling or limiting use of areas on land or in water
Environment aspects
Environmental impact on a global scale
Emissions to air and water
Emissions from transport and material manufacturing (for ex green house gases, and acid substances)

Proposed tools for assessment
• Ecology – EIA with RA & ESA/LCA
• Economy – Investment cost (statutory) and CBA on national economy
• Socio-culture – n.a.

Conclusions – Project level1. A sustainable approach should be applied to select
BAT consideringtechnology-economy-environment-social aspects
2. Stabilisation and solidification in the Oxelösund caseBeneficial use of contaminted sedimentsLess energy consumption and global warming
3. The BAT-approach was necessary for Oxelösund4. One project it´s not significant to the Baltic Sea
issue, further decisions levels should be adressed
