“The self-contained, waterless toilet, designed and built using a $777,000 grant from the Bill & Melinda Gates Foundation, has the capability of heating human waste to a high enough temperature to sterilize human waste and create biochar, a highly porous charcoal, said project principal investigator Karl Linden, professor of environmental engineering. The biochar has a one-two punch in that it can be used to both increase crop yields and sequester carbon dioxide, a greenhouse gas.” - (...)

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.
