|Abstract:||In Sweden; excavation and landfilling are; at present; the most prevailing ways of handling contaminated soil. This presentation will provide examples of different remediation methods that result in the destruction of contaminants; or when it comes to metals; ways to greatly minimise the volume of the contaminated soil. All the examples of the methods given here have the following in common: all have been commercialised in Sweden; and all technologies result in soil clean enough for re-use. The presentation clearly demonstrates the broad spectrum of concepts available for treating a variety of contaminants in soil in an environmentally sustainable way.|
The presented examples have been selected based on the steady and high frequency of objects polluted with PAH-s; chlorinated solvents; nitroaromatic compounds; and metals. The following treatment methods are described in the presentation:
- for PAH-s – biological field treatment; bio-reactor treatment; continuous wet chemical treatment; thermal destruction.
- for chlorinated solvents – cyclical biological treatment; evaporation and capturing (in situ); thermal destruction.
- for nitroaromatic compounds – cyclical biological treatment; physico-chemical destruction.
- for metals – wet chemical treatment performed in batches or by continuous-flow technology.
