Abstract

Abstract A novel process of alkali-heat pretreatment - mixed culture fermentation was proposed to produce butyric acid from rice straw, but generating alkali-heat pretreatment waste (PW) and butyric acid fermentation waste (FW). In this study, the feasibility of methane fermentation from the wastes was confirmed, with the methane production from PW and FW of 351.1 ± 11.8 and 741.5 ± 14.2 mLCH4/gVS, respectively. The initial pH and VFW/VPW of methane fermentation using the mixed waste of PW and FW were optimized at 7.5 and 1.8, respectively. The methane fermentation using the mixed waste was also verified by operating two anaerobic digesters in sequencing batch mode. At the VFW/VPW of 0.25 (actual ratio), methane production was 301.20 mLCH4/gVS with the waste load of 0.64 kgVS/m³/d. When the VFW/VPW was 1.8 (optimal ratio), methane production reached 396.45 mLCH4/gVS at the waste load of 1.20 kgVS/m3/d. This study facilitates the comprehensive utilization of all components within rice straw.
