**Lagos Transitions to Circular Waste Management Model** The Lagos State government is shifting its waste management approach from a linear to a circular model, driven by the city's rapid growth, increased population, and ecological vulnerability. This transition is expected to benefit both the economy and the environment. Lagos, with a population of 22 million, is a rapidly urbanizing megacity that faces significant waste management challenges. The city's traditional linear waste management model, which involves generating, collecting, transporting, and dumping waste, is no longer sufficient. This model was adequate when the city was smaller, consumption was lower, and land for disposal was more abundant. However, with the city's current size and growth rate, the linear model is no longer sustainable. **Waste Management as a Daily Test of Governance** Muyiwa Gbadegesin, managing director of the Lagos State Waste Management Authority (LAWMA), emphasized that waste management is not just a technical service, but a daily test of how a megacity governs itself. It affects various aspects of urban life, including public health, drainage, flooding, real estate values, investor confidence, transport corridors, climate resilience, and the dignity of urban life. At a recent forum hosted by the Property and Environment Writers Association of Nigeria (PEWAN), Gbadegesin highlighted the need for a circular waste management model. He explained that the linear model treats waste as a nuisance to be removed, whereas a circular model views waste as a material stream to be reduced, separated, recovered, processed, and reintroduced into productive use wherever possible. **Transitioning to a Circular Economy** The transition to a circular economy means moving away from the idea that the success of the system is measured only by how much waste is collected and taken away. Instead, success will be measured by how much waste is reduced, reused, and recycled. Gbadegesin emphasized that this is especially important in Lagos, which is a coastal and amphibious city. Poorly handled waste can quickly become a drainage problem, a flood risk, a marine pollution problem, and eventually a public health problem. In practical terms, the transition to a circular economy will involve redesigning the waste management system to prioritize waste reduction, separation, and recycling. This will require a collaborative effort from various stakeholders, including PSP operators, waste managers, and the government. By adopting a circular waste management model, Lagos aims to create a more sustainable and environmentally friendly urban environment.
