Material is decontaminated of a pollutant by using perennial woody plants with the ability to accumulate the pollutant in the leaves in high concentrations. The decontamination is based on a combination of phytoextraction, pollutant transport with the falling of the leaves to the material surface, leaching of the pollutant out of the leaves decomposing on the material surface, and (physico-)chemical fixing of the pollutant in a reactive layer which is bounded by geotextiles and which physically and/or chemically binds the pollutant.
