Armed with plastic bags, they plunge their bare hands into the garbage and start sorting it. Every day, more than 2,300 tons of garbage is dumped at the landfill at Bhalswa that covers an area bigger than 50 football fields, with a pile taller than a 17-story building.

They are among the estimated 20 million people around the world — in rich nations and poor — who are pivotal in keeping cities clean.
