  1. Biofuels Quick Facts

  2. What are biofuels? • Liquid transportation fuels made from plants & other forms of biomass. • Two types • Ethanol-a gasoline type fuel made by fermenting sugars into alcohol. • Biodiesel-a diesel type fuel made by separating glycerin from animal & vegetable oil to create methyl esters.

  3. Sugar cane Corn Sweet sorghum Soybean oil Coconut oil Palm oil Canola oil Jatropha nut oil Trees Grass Agricultural residue Municipal solid wastes What materials can be used to make biofuels? Recent research is making this process less expensive & more energy efficient.

  4. Ethanol or Gasoline?

  5. Pictorial by Graydon Blair of the Utah Biodiesel Cooperative

  6. After Glycerin removal, biodiesel now just needs to be cleaned/purified before use:

  7. Where are biofuels made? • Brazil • Uses sugar cane to make ethanol • Midwestern United States • Uses corn to produce ¼ of the globe’s ethanol • China • 3rd largest supplier of ethanol in the world.

  8. Are biofuels good for the environment? • Biofuels are cleaner burning & reduce emissions of particulate matter. • Biofuels are biodegradable. • Biofuels are nontoxic.

  9. Environmental Issues • Burning fossil fuels increases atmospheric levels of carbon dioxide • Fossil fuels are a finite resource Biodiesel’s Closed Carbon Cycle 30% Increase Graph taken from USF Oceanography webpage

  10. Share of energy consumed by major sectors of the economy

  11. Are special cars required to use biofuels? • Cars, trucks, & farm equipment can all run on low-volume biofuel blends without any alterations. • Flexible Fuel Vehicles (FFV) operate on any combination of ethanol & gasoline. • FFV’s are being sold in the U.S., Brazil, & China.

  12. Benefits of biofuels • Reduce yearly operation costs. • Reduce the need for petroleum • Reduce greenhouse gas emissions • The crops that are used are all renewable resources.
