Abstract: Sustainable energy is the desire of every country in the world and a lot have been invested in other to achieve that. In spite of the efforts vested on renewable energy, over 70% of the global population rely on non-renewable energy also called fossil fuels for their daily energy requirements. In some countries, solar, wind, hydropower, biomass and other municipal waste are being harnessed to generate energy but those country rarely make up to 20% of the world population. This work is channeled toward studying the energy generation by co-anaerobic digestion of pig waste and corn chaff. Three digesters of equal volumes were charged with three co-substrate ratios - pig dung to Corn chaff, 800:800, 1120:480 and 1400:200 equivalent to Carbon to Nitrogen ratio (C:N) of 21.5, 19.6 and 17.4 respectively. The 21.5 C:N digester gave a higher yield of biogas and ultimate biomethane. Co-digestion of energy crops like maize and its derivatives and organic manure like pig dung with C:N of 20:30 is thus preferred over mono-digestion. Carbon to nitrogen (C:N) ratio has been identified as the key parameter for improving the digestion of substrates. Higher bio-degradability, improvement in C:N ratio and environmental-friendly sludge production has been established as the hallmarks of co-digestion process
