#21 Waste Concern: Turning Urban Waste into Resource

DescriptionWhat if city garbage could feed farms, clean neighborhoods, and create jobs—all at once? This episode tells the story of Waste Concern, a pioneering social enterprise based in Bangladesh that is redefining urban waste management in South Asia. In cities like Dhaka, where up to 80% of municipal solid waste is organic and poorly managed, Waste Concern developed a decentralized composting model that converts household food waste into high-quality fertilizer for farmers. The model not only helps divert tons of waste from landfills but also reduces methane emissions, improves public health, and restores degraded soils in rural areas.We explore how Waste Concern went from one community pilot to dozens of sites across Bangladesh, catalyzing a national composting movement and influencing government waste policy. The organization built a scalable system by combining low-cost technology, micro-enterprise job creation, and strong community participation. Along the way, it pioneered a hybrid NGO-consulting model and leveraged international partnerships—including carbon finance mechanisms and public-private collaborations—to fund large-scale infrastructure like Dhaka’s 700-ton composting facility. The model has since been replicated in Sri Lanka, Vietnam, and beyond, demonstrating how smart, inclusive design can solve deeply rooted environmental and public health challenges.This episode is about more than waste. It’s about the power of systems thinking, local action, and entrepreneurial persistence to reimagine how cities manage their most overlooked resource.Key wordsWaste Concern, Urban composting, Circular economy, Sustainable cities, Community-based waste management, Climate and sanitation solutions
