MCRC has designed and developed various biogas systems to produce methane for sustainable fuel supply in rural areas. Different substrates, including cow dung, food waste, vegetable waste, algal biomass, and leaf biomass, have been tested for biogas production. A consortium of bacteria was created to enhance biogas yield. To improve the anaerobic digestion process, specially designed reactors with capacities of 50 L and 60 L were fabricated. Additionally, various treatments with phototrophic bacteria and phosphate-solubilizing bacteria on cow dung were studied to enhance the quality of the feed slurry. The results showed that the methane content was significantly higher in all treated samples compared to the untreated control.
