Verification of the energy self-sufficiency by biogas production from cow-buffalo farm waste

Adherence to the Kyoto Protocol and evermore stringent restrictions imposed by the European Union have made recourse to renewable energy sources evermore compelling as well as strongly incentivised. So, a mathematical model was devised to calculate the amount of biogas producible from biomass through anaerobic fermentation. In particular, installing a co-generator of electricity and heat which runs on farm waste biogas was verified. The results show that a 35kW co-generator is not only able to make a 250 head farm energy autonomous, but can create an extra source of income by selling surplus electricity back to the grid.
