The presence of contaminated sites in ever increasing numbers brings several management problems and often leads to a waste of important resources, such as soils and water which cannot be utilised. Remediation with conventional technologies is sometimes unfeasible due to economic reasons or for the opposition of the public opinion, but it is often the only available alternative. Since many years, biological techniques for remediation, bioremediation and phytoremediation, have been studied; they can give acceptable results with a lower environmental impact, even if with longer time periods. In particular, the use of higher plants in decontamination has been limited by legislation constraints, and also for lack of plant species, which can be really effective towards specific contaminants. In this paper the remediation potential of a short rotation coppicing with poplars selected for bioenergy production and for specific remediation needs of two national interest contaminated sites: 1) the agricultur- al soil polluted with lindane and isomers in the River Sacco valley in the roman province, 2) the soil of the industrial area of the ENI Oil Island by Porto Marghera, polluted by multiple heavy metals. It is also shown and evaluated an example of manure spreading on a poplar plantation by a farm of Torre in Pietra in the Agro Romano.
