  1. Ecosan Training Courses for TSC officials Developing Capacity for Ecological Sanitation in India Reuse of Energy (Biogas) Dipl. Ing. Martin Wafler, seecon international, Austria

  2. Ecocycle organic waste from households and industries food production at farms co-digestion of waste and manure re-use of nutrients re-use of energy source: www.kristianstad.se/

  3. Possible Benefits of Biogas Plants to the End-users Under the right conditions a biogas plant yields several benefits to end-users: Improved sanitation: reduction of pathogens, worm eggs and flies; Environmental advantages: fertilizer substitution, less greenhouse gas emission; Reduction of workload: less firewood collection, better cooking performance; Production of energy: lighting, heat, electricity, etc.; Improved indoor air quality: less smoke and harmful particle emission of biogas stoove compared to wood or dung fuels; Economical benefits: substitution of spendings on expensive fuels and fertilizers;

  4. Why Shall We Collect and Re-use Biogas? Environmental Advantages Local environmental advantages through protection of forests, soil, water and air. Global environmental benefits through reduced green house gas emissions. Global Warming Potential (GWP)Carbon Dioxide (CO2) has a GWP of exactly 1 (since it is the baseline unit to which all other greenhouse gases are compared)

  5. Why Shall We Collect and Re-use Biogas? Social Advantages Reduction of workload, mainly for women, in firewood collection and cooking

  6. Why Shall We Collect and Re-use Biogas? Health Advantages Reduction of respiratory chest diseases, lung cancer, cataract and other eye infections, lung infections Indoor Air Pollution Improved Air Quality Using Biogas Stoove source: http://www.abdn.ac.uk/ photo: M. Wafler

  7. Why Shall We Collect and Re-use Biogas? Economic Advantages Substitute to fire wood, LPG, dung cake in e.g. cooking 1 m3 Biogas (@ ca. 6 kWh/m3) is equivalent to:

  8. Why Shall We Collect and Re-use Biogas? = 30 m3 BIOGAS = INR. 400 (@ 14.2 kg of LPG per container)
