The increased market demand for household cooking fuel in Kenya provides an opportunity to improve livelihoods and the environment. This project unlocks the potential in human feces and other waste streams by transforming it into an affordable household cooking fuel. Sanivation, a partner organization, produces charcoal briquettes derived from human and agricultural waste that is cheaper than traditional charcoal. These fuel briquettes produce less smoke than traditional charcoal, consequently reducing the users’ exposure to toxic fumes and reducing indoor air pollution. Feces to Fuel aims to aid Sanivation with the technical and design work necessary to expand their business and scale production to 180 tons of fuel derived from waste products per month.
