Abstract: Biogas fermentation of abandoned lotus leaf was evaluated in this research. The main components of the lotus leaf were analyzed, then anaerobic biogas fermentation were carried out using lotus leaves as raw material with activated sludge as inoculums. Rice stalk were used as a control. After 35 days fermentation, the biogas production was 167.0 mL/g, while the methane content of the gas was65.72%, which were 15.57% and 12.25% higher than those of fermentation with rice straw as row material.The biogas production was 184.5 mL/g, methane content of the biogas was 70.68%, when lotus leaves and rice straw were mixed with ratio of 1∶1 as raw material, which are 27.68%, 20.72% higher than those of fermentation with rice straw as only raw material. The TS and VS content of Lotus leaf changes before and after fermentation were 3.77%, 15.17%, and pH maintained at about 7. These results implied that Lotus leaf might be a suitable resource for biogas production.
