CONCLUSIONS
Co-digestion of SM and CM has shown a significant effect on anaerobic digestion. The results showed that MR had significant (p 0.05) effect on substrate temperature, pH and biogas production. The mean substrate temperature and pH during digestion were 28.5 ± 2.5 oC and 6.80 ± 0.55, respectively. MRs 0:1 (CM only) and 1:0 (SM only) produced average daily biogas of 0.52 and 0.38 L kg-1 VS fed day-1, respectively. MR 1:1 appeared to be the optimum as it produced the highest average daily biogas, which was 69.2% and 131.6% higher than productions from MRs 0:1 and 1:0, respectively.
