Work with Rag Pickers and Solid Waste Management
SMS began work with rag pickers in 1998, with the launch of Parisar Vikas. Parisar Vikas, one of the NGO's key programmes, aims to recycle waste and create zero-waste cities.  It aims to organize the waste-pickers, educate them, and provide the women with health and counselling services. More than 5,000 women have so far benefitted from the organization’s continued pursuit of its goal that waste-picking should be given its rightful place in the economy of a city. SMS was responsible for setting up the city’s first child-care center for children of waste-picker women, started an adult literacy campaign in Chembur and aided the formation of the rag-pickers’ union in 1989-90.
