Microbial fuel cells play a key role in generating wealth out of waste as they serve the binary purpose of electricity production along with waste treatment. A variety of organic substances can be used as substrates in microbial fuel cells. In this work, three substrates naturally obtained as dairy farm waste, viz. cattle manure, yogurt waste, and cow urine along with their various combinations were tested for power generation in a microbial fuel cell. All three substrates are a promising source of electrogenic bacteria. The potential use of aluminium as electrode material for electricity generation in microbial fuel cell was also investigated. The output circuit voltage was recorded at regular time intervals over a period of around 15-25 days. Maximum output voltage of 1.170 V was recorded for cattle manure as substrate on graphite electrode with a stabilization period of 16 days. The combination of cattle manure and yogurt waste on aluminium electrode gave peak output voltage of 1.122 V with a stabilization period of 10 days. The addition of cow urine did not show any significant increase in the output.
