Official estimates predict that in 5 years the waste produced by the city will almost double to 18,000 tonnes a day. Bhalswa landfill towers above its surroundings. At 50 metres high and 40 acres across, it is a flaming mountain of decomposing waste. Due to social stigma across India, rag pickers face terrible discrimination and communities are often blighted by alcoholism, literacy and drug abuse. Campaigners say many of the children working on the municipal sites in Delhi are orphans or separated and thus highly vulnerable to sexual abuse or being trafficked into sex slavery.
