Biofuel Presentation

  1. 1. Plant-based biofuels for rural community development<br />PalizaShrestha, Mount Holyoke College<br />ES-390<br />
  2. 2. Background<br /><ul><li>Current ways of energy use is unsustainable
  3. 3. Demand for renewable energy sources is expected to rise in future
  4. 4. Biofuel gaining worldwide popularity since first manufactured in Europe
  5. 5. U.S. promoting industrial biofuel to solve climate crisis
  6. 6. Small scale biofuel projects sprouting in rural communities</li></li></ul><li>What is biofuel?<br /><ul><li>Liquid fuel produced from plant products
  7. 7. Category: Biodiesel, ethanol, methanol, pure vegetable oil
  8. 8. An alternative to petroleum based fuel
  9. 9. Biodiesel feed stocks:
  10. 10. Palm
  11. 11. Coconut
  12. 12. Jatrophacurcas
  13. 13. Rapeseed/ Mustard seed
  14. 14. Sunflower
  15. 15. Corn
  16. 16. Soybean
  17. 17. Peanuts
  18. 18. Algae
  19. 19. Used restaurant oil
  20. 20. Animal fats</li></ul>Coconut seeds<br />Pond Algae<br />Palm seeds<br />Jatropha seeds<br />Rapeseeds<br />Sunflower seeds<br />Soybean seeds<br />Corn<br />
  21. 21. How is biodiesel made?<br />Alcohol (Ethanol, Methanol)<br />Catalyst <br />(NaOH/KOH)<br /> & HEAT!<br />Biodiesel<br />Esters of 3 <br />fatty acid chains<br />Glycerine molecule which<br /> is separated out<br />Vegetable<br />Oil Molecule<br />
  22. 22. Industrial biofuel and environmental degradation<br />Massive deforestation in tropical rainforest in Indonesia to convert to oil palm plantations<br />8% of global CO2 emissions<br />21% of Brazil’s agricultural land converted to soy bean plantation <br />Displaced over 300,000 people<br />Since Jan 2003, 70,000 km2 of Amazon rainforest cleared for biofuel production<br />Forests and soil store 3x the amount of CO2 than does the atmosphere<br />More….<br />High production costs (energy)<br />Competition between food crop and fuel crop <br />Price increases in world grains, cereals and vegetable oils<br />
  23. 23. Can biofuels work sustainably?<br />I think so…<br />At the local level in isolated rural communities with<br /><ul><li> intermingled with development projects
  24. 24. effective government policies to protect farmers from competition
  25. 25. decentralized
  26. 26. Small scale biodiesel plants in developing countries had led to
  27. 27. rural electrification
  28. 28. improving irrigation & agriculture
  29. 29. job creation
  30. 30. women empowerment
  31. 31. power to local community
  32. 32. self sufficiency</li></li></ul><li>Engine driven <br />oil expeller<br />An hour of pedaling activity converts <br />vegetable oil to biodiesel in an Indian village.<br />The fuel is used to run irrigation pumps, tillers,<br />rice hulling mills and generate electricity.<br />Biodiesel plant to power shea butter<br /> processing equipment, Ghana, initiated <br />by women’s group and UNIFEM<br />
  33. 33. Steps to initiating pilot projects in rural communities<br />Mobilize community groups , e.g. 10 to 15 households<br />Awareness workshops including gender sensitivity<br />Engage local men and women in interactive dialogue and discussions<br />Install irrigation pump and oil expeller for each community group <br />Provide skill training and instruction manuals<br />Form Village energy committee<br />Encourage household to plant jatropha plants in their private wastelands or in poorer sections of their field, e.g. on the borders of the fields<br />Conduct technical and business skill training to women from preparing organic fertilizer from oil cake to producing vegetable cash crops to sell in the market<br />Establish a small micro-finance bank so villagers can take loans<br />
