Study on the potential of biogas production from grape seed by anaerobic digestion before and after oil-extracting.

This paper reported that biogas production from grape seed and its oil-extracted waste by batch fermentation process at 25 ℃.The result indicated that the biogas production from grape seed was 473.65 mL/g·TS or 484.55 mL/g·VS,the energy efficiency was 37.25%;and for its oil-extracted waste,the biogas production was 450.03 mL/g·TS or 460.44 mL/g·VS,the energy efficiency was 36.43%.
