Abstract:
The use of energy crops on contaminated soils must conciliate the ability in removing the contaminating element with the suitability for energy conversion. The aim of the study was to examine the influence of Cu on the main parameters associated with energy use of giant reed (Arundo donax L.). The plants were grown in pot on soil contaminated with increasing concentration (0, 200, 400, and 800 ppm) of copper (Cu) and analyzed for the calorific values, the ash content, the elemental composition and potential yield of methane. The effect of Cu on the growth of the Arundo was evident just at the maximum concentration (800 ppm). The Lower Heating Value (LHV) was significantly different between the control (15.51 MJ kg-1dw) and the plants contaminated with 800 ppm (14.88 MJ kg-1dw). The elemental analysis showed some differences for the carbon (higher in the control) and the oxygen (statistically lower in the control compared to 800 ppm). An estimation of the potential production of methane based on the elemental analysis (Buswell’s formula) indicated that the plants grown at the highest dosages (400 and 800 ppm) could give the lowest yield in anaerobic digestion.
