On site remediation of contaminated soil by use of industrial by- products Print


About 80 000 potentially contaminated sites have been identified in Sweden and remediation of them using excavation and landfilling is economically unreasonable. Various treatment techniques can reduce hazard of the contaminated soil by for example destroying, separating or stabilising its hazardous components.
The goal of the project is to develop and evaluate practical sequences of techniques for on site re-mediation of soil contaminated with mixed (i.e. organic and inorganic) substances. It will access how one technique that is efficient for destruction of organic contaminants, e.g. thermal treatment, should be combined with other methods, such as separation, concentration and stabilisation to achieve the desired result.


In case when chemical stabilisation is included for the treatment of the separated contaminants, the utilisation of industrial by-products, for example, from steel (iron oxides) and energy industries (ashes) will be accessed as an environmentally and recourse-efficient option. Soil contaminated with a mixture of PAH (polyaromathic hydrocarbons) and CCA (chromated copper arsenate) excavated from a former wood impregnation industrial site will be used in laboratory and field experiments. Several treatment sequences will be tested, for example, particle separation, chemical extraction of organic and inorganic contaminants using cost efficient and environmentally non-disruptive substances followed by stabilisation of fines and washing residues (sludge).
