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±10Nm<sup>3</sup>CH<inf>4</inf>Mg<sup>-1</sup>TS<sup>-1</sup> and 245±26Nm<sup>3</sup> CH<inf>4</inf>Mg<sup>-1</sup>TS<sup>-1</sup>, 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. 12,292Nm<sup>3</sup> CH<inf>4</inf>Ha<sup>-1</sup> and 4549Nm<sup>3</sup>CH<inf>4</inf>Ha<sup>-1</sup>, 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<sup>-3</sup>CH<inf>4</inf><sup>-1</sup> and 0.81€Nm<sup>-3</sup>CH<inf>4</inf><sup>-1</sup>, and 0.10€kWh<inf>EE</inf><sup>-1</sup> and 0.19€kWh<inf>EE</inf><sup>-1</sup> for biomethane and electricity production, and for giant cane and corn mixtures respectively.

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±10Nm3CHFile | Dimensione | Formato | |
