New energy crop giant cane (Arundo donax L.) can substitute traditional energy crops increasing biogas yield and reducing costs / L. Corno, R. Pilu, F. Tambone, B. Scaglia, F. Adani. - In: BIORESOURCE TECHNOLOGY. - ISSN 0960-8524. - 191(2015), pp. 197-204. [10.1016/j.biortech.2015.05.015]
Abstract:
Giant cane is a promising non-food crop for biogas production. Giant cane and corn silages coming from full-scale fields were tested, in mixtures with pig slurry, for biomethane production by a continuous stirred tank lab-scale-reactor (CSTR) approach. Results indicated that giant cane produced less biomethane than corn, i.e. 174±10Nm3CH4 Mg-1TS-1 and 245±26Nm3 CH4 Mg-1TS-1, respectively. On the other hand, because of its high field biomass production, the biogas obtainable per Ha was higher for giant cane than for corn, i.e. 12,292Nm3 CH4 Ha-1 and 4549Nm3CH4 Ha-1, respectively. Low energetic and agronomic inputs for giant cane cultivation led to a considerable reduction in the costs of producing both electricity and biomethane, i.e. 0.50€Nm-3CH4 -1 and 0.81€Nm-3CH4 -1, and 0.10€kWhEE -1 and 0.19€kWhEE -1 for biomethane and electricity production, and for giant cane and corn mixtures respectively.
