Phytoextraction ability of some fast growing plant species leads to the idea of connecting biomass production with soil remediation of contaminated industrial zones and regions. This biomass will contain significant amount of heavy metals and its energetic utization has to be considered carefully to minimize negative environmental impacts. This study was focused on potential disposal methods of willowtrees contaminated by heavy metals (Cd, Cu, Pb, Zn) with the emphasis on energetic utilization of biomass. Composting seems to be suitable pretreatment method resulting in decrease of heavy metals leachability and biomass weight reduction. The possibility of willowtrees application for energetic purposes was investigated and consequently incineration tests of willowtrees samples in fluidized bed reactor were realized. Distribution of selected heavy metals in different ash fractions and treatment methods of produced ashes were studied as well.
