Characteristics of Anaerobic Co-Digestion of Corn Straw and Cabbage for Biogas Production

In order to study characteristics of anaerobic co-digestion of corn straw and cabbage, the experiment was performed with corn straw to cabbage (S:C) of 4:1, 6:1 and 10:1 based on total solids (TS) at 35±1°C at initial TS of 8%. The effects of co-digestion on pH, volatile fatty acid (VFA), and biogas...

Summary:In order to study characteristics of anaerobic co-digestion of corn straw and cabbage, the experiment was performed with corn straw to cabbage (S:C) of 4:1, 6:1 and 10:1 based on total solids (TS) at 35±1°C at initial TS of 8%. The effects of co-digestion on pH, volatile fatty acid (VFA), and biogas yield were examined. Results showed that the S:C of 4:1 was optimal with accumulative biogas yield of 334.53mL/gTS compared with S:C of 6:1 and 10:1 with accumulative biogas yield of 289.31mL/gTS and 311.37 mL/gTS, respectively. This should be attributed to the high VFA concentration achieved by S:C of 4:1.
