Abstract

The demand for land for the cultivation of biomass for bioenergy is increasing the food versus fuel conflicts. These conflicts can be overtaken by producing dedicated crops for energy on marginal/contaminated land, reducing the indirect land-use change (ILUC) impacts. There-fore, the aim of this work was to assess if the production of energy from giant reed cultivated in heavy metals contaminated soils is sustainable (environmentally and socioeconomically). Results show that the productivity loss, especially in Cr and Cu contaminated soils, lessens the energy and greenhouse savings. Yet, the quality of soil is improved. In Zn, Pb, Cd and Ni contaminated soils, the adverse effect on the productivity was not as significant as in Cr and Cu contaminated soils and therefore, limited effects on the environmental and socio-economic aspects, compared to non-contaminated soils, were observed.
