Across many rapidly expanding coastal cities in West Africa, municipal governments struggle to manage the mounting volumes of domestic solid waste. In response to unreliable public collection services, community-led recycling initiatives have emerged as a vital mechanism for urban sanitation. These neighborhood cooperatives organize local residents to sort household waste into organic materials, plastics, and metals before collection. For instance, in several suburbs of Lagos, youth groups have established informal sorting hubs where plastic bottles are bundled and sold to recycling plants. While these local efforts generate modest income for collectors and noticeably reduce roadside littering, their primary significance lies in mitigating severe urban flooding. Uncollected plastic waste frequently clogs drainage channels during the heavy rainy season, causing catastrophic floods that destroy property and displace residents. By diverting synthetic materials away from open gutters and storm drains, community recycling directly addresses the root cause of seasonal urban inundation.
