Biogas Production from Sugar Cane Press Mud and Sugar Cane Bagasse by Anaerobic Co-Digestion (original) (raw)
International Journal of Engineering Applied Sciences and Technology
The result of this research is to determine the ratio of the combination (co-digestion) of Press Mud and Bagasse to the volume of biogas production, and for the bagasse as a single substrate. Samples were tested and used without any pre-treatment. Biogas production volume and the effect of co-digestion on biogas production are discussed further in the paper. The results showed that the digester with 9% total solids when fed considering only bagasse as a single feedstock gave good amount of biogas compared to 6% or 12% total solid. The study also investigates the different factors which affected the biogas generation from sugar industry waste bagasse. In this paper, sugarcane bagasse was used as a feedstock for biogas generation in an anaerobic type lab scale digester similarly a co digestion of bagasse and press mud was also observed. Inoculum from cow dung was used in the above experiments. The anaerobic digestion as well as the co digestion was carried out in batch mode with mesophilic temperature of 35ºC and 50 days of hydraulic retention time. The cumulative gas production achieved for both (only bagasse digestion and co-digestion of press mud and bagasse) is explained further in this paper. Temperature, pH, biogas flow etc was measured using respective meters. Bagasse is one of the suitable wastes for biogas generation through anaerobic digestion. And without any doubt bagasse and press mud can also be used together in co digestion process to see enhanced gas generation and organic manure generation from the experiments.
