The study looked at how to make more biogas from cow dung and fruit/vegetable waste. They found that keeping the temperature between 25-35 °C, having a pH of 8, and adding nutrients like CaCO3 and NH3 in a certain ratio can give the best results. By following these conditions, they were able to produce 1.45 kg of gas on the 6th day of the process. This shows that making cooking gas from plant and animal waste is possible and can be profitable.
