Millions of poor people in the teeming cities of the developing countries support themselves and their families by directly or indirectly participating in waste collection and recycling. For instance, over 20,000 women work as paper pickers in Ahmedabad city (Salahuddin & Shamim, 1992). It has been estimated that up to 150,000 waste pickers are active in Municipal Corporation of Delhi area (Chaturvedi, 1998). In fact, all cities in the developing world have a sizeable population that ekes out a living from picking waste generated by their wealthier neighbours. This is the most vulnerable and marginalised group that comprises mostly of women and children.
