  16. Domestic Energy Resource … Biodiesel • Reduce dependency on imported fuel • Improve environment and public health • Increase our domestic rural economy • Increase energy sustainability • Promote homeland security • Increase lubricity for engines • Pay less for energy - maybe

  17. Environmental Impacts of Biodiesel Large Reductions in: CO2 SOx Particulates Odor Slight Increase in: NOx

  18. Photosynthesis Carbon Dioxide Oxygen

  19. Nitrogen Fixation Nitrogen

  20. Biodiesel Yield 1.25 Gallons B100 per bushel 62 Gallons B100 310 Gallons B20 1240 Gallons B5 1.1 tons of Soybean Meal 50 Bushels Soybeans per acre

  21. Make Sure it’s Biodiesel! ASTM D-6751

  22. Biodiesel Checklist • Meets ASTM D 6751 Standards • Fuel filters • Cold weather precautions • Engine compatibility • Wipe spills immediately • Sore rags in safety can • Use within 6 months

  23. Making Your Own Biodiesel • Safety • Compliance w/ environmental regulations • Feedstock availability • Time commitment • Economics • Handling of byproducts • Engine performance

  24. Transesterification Fuel-Grade Biodiesel Feedstock Oil Methanol Catalyst Drier Water Reactor Washer Separator Raw Biodiesel Wash Water Glycerol (with methanol) Glycerin

  25. Glycerol Landfill as hazardous waste Dispose in anaerobic manure digester Industrial incineration at temperature > 500 F Special permission from PADEP required Land application prohibited by law! Glycerin (after methanol removed) Composting Use as an ingredient for: Degreaser Soap Dust suppressant Animal feed Disposal Options

  26. Disposal Options • Wash Water • Public sanitary sewer (with permission) • Must be prevented from entering waterways, storm sewers, and water runoff channels • Contaminating waterways with wash water is illegal

  27. THERE’S NO SILVER BULLET Lone Ranger Look for Site-Specific Energy Solutions

  28. Alternative Energy Sources

  29. ENERGY EFFICIENCY

  30. Photosynthesis Carbon Dioxide Oxygen
