Abstract: In the field of renewable energy, national targets imposed by the European Directive on promoting the use of energy from renewable sources is to reach 24% of gross final consumption of energy by 2020. This paper presents a solution for this target and for sustainable management of ash and slag closed deposits by plantation of energetic crops. Process of plantation was assessed by tracking energetic crops by determining the capacity of metals accumulation in wood biomass, correlations between the crops diameter and height, chemical composition of ash. The obtained data were compared with similar data recorded for other intensive crops. Amount of biomass harvested from 5.3 kg/m2 green table (after 3 years) reveals a good development and production of plantation wood, grown on the surface of ash and slag deposit. Based on obtained experimental data, we propose a model of vegetation with energy plants (Salix sp.) of a deposit of ash and slag after its closure was achieved. By implementing experimental model these surfaces can be reinserted in landscape and economic circuit, being in accordance with the provisions of Order No. 757 of 26/11/2004 for approval the Technical Normative of Waste Storage.
