Standing atop towering piles of discarded goods in the eastern district of Delhi, an Indian ragpicker looks for metal, cardboard and plastics that can be sold to scrap dealers. Like him, dozens of informal workers scavenge amid the stench and toxic fumes rising from decomposing waste, while hundreds of crows and birds of prey circle above.

Landfills are often considered a cheap disposal method, because long-term environmental damage is not factored in. Landfills lacking methane capture and systems to collect fluids that form when rainwater percolates through waste materials release toxic substances into soil and water.Nature – Identification of prevalent leachate percolation of municipal solid waste landfill, 2024 In Delhi, this “garbage juice” flows into the Yamuna River, a tributary of the Ganges.
