At a busy market in Lagos, Nigeria, a simple idea is turning fruit waste into a valuable source of energy. Traders at Ikosi Market generate tons of spoiled produce every day, much of which used to end up rotting in a nearby landfill. Now, a pilot biogas plant is transforming that waste into electricity and cooking gas, helping power stalls, lighting the market at night and supporting small businesses. While the system still faces challenges, it is already cutting costs for vendors, creating jobs and reducing pollution. The project offers a glimpse of how cities can turn everyday waste into practical, sustainable energy solutions.
