Land-starved Mumbai currently discards 11,000 metric tons of refuse every day in three dump yards that together occupy more than 300 hectares. At going market rates, that land would be worth as much as $4.4 billion if it were sold and used for housing. Meanwhile, 6.5 million people, or half of Mumbai’s population, live in slums without basic sanitation and safe drinking water. An average Indian would need to work for three centuries to pay for a luxury home in Mumbai, comparing home costs with average annual incomes, making it the least affordable city in the world for locals. Meanwhile the Deonar dump site, Asia’s biggest and arguably oldest that opened in 1927, sits on 130 hectares in eastern Mumbai and takes half of the city’s daily refuse. Its trash mountain is so high it could bury the White House – twice over. Most Indian households do not separate garbage for recycling. What reaches the landfill is a mix of kitchen refuse, plastic, glass, paper, metal and construction debris.
