Urban waste management has become a critical environmental issue. Poor handling of solid waste leads to pollution, creating breeding grounds for disease-carrying organisms. Mumbai’s Deonar Landfill, established in 1927, stands as the oldest and largest of its kind in India. Spanning 132 hectares, it processes thousands of tonnes of waste daily, with piles as high as an 18-storey building. The landfill has adversely affected the health of nearby residents, with frequent fires exacerbating air pollution and earning the surrounding neighborhoods the title of the most polluted in 2015.
