4.6 billion people across the developing world lack adequate treatment of their feces and urine. ElectroSan will apply electrochemical cells that recover nitrogen from human urine. This product will be used to disinfect human feces and produce income as a fertilizer, making sanitation affordable in low-income communities like Mukuru, an urban Nairobi slum. This intervention can catalytically improve public health and environmental quality by treating and creating value-added products from waste.
