Flying Toilets in Kenya

Nairobi, the capital of Kenya, is officially home to three million people, though some suspect the real number could be twice that. Half live in slums where the infrastructure is minimal. Sanitation and access to clean water are especially limited, as reporter Richard Lough discovered when he visited a slum called Kibera.

Another group working in in Kibera is Peepoople. They’ve developed a disposable toilet bag that processes human waste into safe fertilizer.
