NEW DELHI – The scavengers wait patiently for a dump truck to tip the trash on the summit of the landfill outside New Delhi.
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.
And every day, thousands of these informal workers climb the precarious slopes to pick through what can be salvaged. They are among the estimated 20 million people around the world — in rich nations and poor — who are pivotal in keeping cities clean, alongside paid sanitation employees.
