Biodiesel
Glycerin
Biodiesel
Benefits:
- Processing technology is relatively inexpensive and simple
- $0.67 / gallon ($0.19 / liter)
- May be blended with petroleum diesel
- Requires no diesel engine retrofitting for blends
- EPA-recognized alternative fuel with relatively low emissions
Biodiesel
Benefits:
Torque Nm
Power (kW)
- Negligible power / torque loss relative to fossil fuels

Workplan – August 25, 2006
Two Year Workplan:
- Characterize commercial and industrial sources
- Quantify the amount of waste oils and fats impacting the sewers
- Develop capacity for biodiesel development in Ambos Nogales
- Submit biodiesel samples for ASTM standards testing
- Use 20% blend of biodiesel in emergency response vehicles
- Evaluate diesel emissions pre and post B20 use.
- Identify commercial markets for biodiesel and glycerin
- Promote public outreach regarding adequate disposal of waste fats
- Identify a strategy for expanding production
