A Columbia University professor of environmental engineering has teamed up with a social enterprise in Accra, Ghana, to turn “fecal sludge” into biodiesel or methane fuel. The project, called the “Next-Generation Urban Sanitation Facility,” is in cooperation with Waste Enterprisers and is being underwritten by a recently announced $1.5 million grant from the Bill & Melinda Gates Foundation.
Half the people in the developing world – some 2.5 billion people – lack access to safe sanitation, according the Gates foundation. “1.2 billion people practice open defecation, meaning they have no sanitation facilities at all, and 1.3 billion people use unsafe latrines. Most of these people live in rural areas, but as urbanization increases, the crisis is spreading to towns and cities as well.”
