Development of a Biogas Waste-to-Energy Map for the City of Ibadan, Nigeria

The city of Ibadan grapples with two pressing issues: inadequate waste management, causing environmental and health problems, and a deficient power supply hampering socio-economic activities. To tackle these challenges, we propose implementing a waste-to-energy system utilizing anaerobic digestion technology as a renewable energy solution. This solution would address the electricity crisis and enhance waste management. This study quantifies the organic waste generated and collected across Ibadan's 11 local government areas, forming a waste-to-energy map. This map provides valuable insights for policymakers and potential investors in waste-to-energy technology. The result shows that the city generates approximately 821,299 tons of waste, with the potential to generate 473,389 kWh of electricity. However, the current waste collection efficiency stands at 45%, yielding 344,945 tons and 215,177 kWh of electricity. Enhancing waste collection efficiency through improved management can transform municipal waste into a reliable renewable energy source, ameliorating both electricity supply and waste management issues.
