what is human waste used for
The companies, prisons and cities making energy from human waste. The 'ick' factor is inescapable but human waste is a cost-efficient way to produce energy. At Bugesera prison in Rwanda, prisoners do what prisoners usually do: eat, sleep, work, co-exist in a highly confined space. But the Bugesera inmates, leaders of Rwanda's genocide, are also unlikely sustainable business pioneers. Their human waste is turned into energy that runs the prison.
