Massive solid waste accumulation has become an environmental, health and aesthetic hazard for India's cities. Urban India generates 188,500 tonnes of trash a day. In the absence of infrastructure to handle the issue, a large, informal waste-picking and recycling industry has developed among the urban poor. This unpaid, unprotected "army of green workers" collects, sorts and recycles the city's discards to trade for small returns.Pune has give an army of mostly Dalit ("untouchable") women the sole rights to collect and recycle the city's mountains of trash. Pune's door-to-door garbage collection service owned and operated by the waste pickers themselves is one of the only examples of a pro-poor public private waste management partnership in India.
