Willow trees are cost-efficient cleaners of contaminated soil
Using broad-leaved trees such as willow trees in the phytoremediation of contaminated soils constitutes a cost-efficient method for restoring mining areas and landfills, according to a research project led by the University of Eastern Finland. Funded by the EU, the project studied willow tree growth in contaminated soils in Finland and Russia."This is a cost-efficient solution for purifying and restoring contaminated soils. There is no need for earth-moving, as harmful materials can be extracted from the soil naturally, with the help of plants. Furthermore, the wood biomass grown in the
