  3. Sanitation for Energy • Productive sanitation means making use of human excreta for nutrients, organic matter, water and energy • The sustainable and hygienic use of human excreta protects water quality, health and the environment as well as being a source of renewable energy How sanitation leads to energy Photo credit: IARC

  4. Sanitation for energy • Anaerobic digestion is a biological process to breakdown organic matter by bacteria • Anaerobic means in the absence of oxygen • A byproduct of this process is methane gas biogas Photo credit: Ashden.org

  5. Sanitation for energy • Methane gas ix extracted from organic waste • This gas is used to drive turbines or combustion engines or burned • Biogas energy is often used at the location where it was produced (lighting, heating) Anaerobic digestion Photo credit: Ashden.org

  6. Sanitation for energy • Reduces carbon emissions by converting methane to CO2 and water • Digested slurry byproduct can be used as fertilizer • Improves indoor air quality • 6 kWh/m3 = approx. 0.5 L of diesel oil Benefits of biogas Photo credit: Ashden.org Photo credit: WeSustainLife.org
