Construction of a pilot scale biogas digester at the University of Ibadan Dairy Farm, Abadina

The quest for cleaner energy sources and renewable energy has become a drive force in the current energy market, creating a gradual shift from total dependence on fossil fuel. Production of biogas through the anaerobic digestion of organic wastes provides an alternative for energy supply, recovery a...
