Dharavi is easily one of the most recognised residential areas in the world. It is also one of the world's largest slums. Dharavi is a large area situated between Mumbai's two main suburban railway lines, the Western and Central Railways. It is also adjacent to Mumbai Airport. To the west of Dharavi are Mahim and Bandra, and to the north lies the Mithi River. The Mithi River empties into the Arabian Sea through the Mahim Creek. The area of Antop Hill lies to the east while the locality called Matunga is located in the South. It may be portrayed as a place of informal economy and cramped quarters, but within this bustling labyrinthine settlement lies the rich history of the diverse communities that call this place home. In Dharavi, despite its cramped quarters and challenging living conditions, the residents have managed to build a thriving micro-economy – the recycling industry.
