In one of Africa's largest dumps, some residents are making a living by collecting and recycling hair extensions from mountains of rubbish.

Nairobi's Dandora Municipal Dumpsite stretches as far as the eye can see. It was declared full in 2001 but has remained active, with 850 to 1,500 tons of waste arriving every day.

But for thousands of Kenyans, the dump is their means of existence.

Winnie Wanjira, 31, is one of an estimated 6,000 people making their living by scavenging in the rubbish. Some people raise pigs on the organic waste, while others find items to sell. Wanjira has tapped into the multi-billion-dollar global hair care industry, buying hair extensions collected by young boys in the dump and then selling it to beauty salons for a small profit.
