What is Biodiesel?
A renewable substitute for diesel fuel made from animal
fats or vegetable oils
The National Biodiesel Board
Headquarters of the National Biodiesel Board
Jefferson, City Missouri
Who is the National Biodiesel Board?
• Non-profit Trade Association for the US Biodiesel Industry
• Coordinating body for Research, Tech Development, Policy
• Founded in 1992
• Supports biodiesel from all sustainable feedstocks and a
multitude of process technologies.
Who is the National Biodiesel Board?
Biodiesel: Advanced Biofuel, Here Now
Nationwide Production Biodiesel is produced in every region of the country.
Biodiesel Feedstocks (EPA Approved Advanced Biofuel)
Soybean oil
Corn oil from ethanol plants
Canola
Camelina
Animal fats
Recycled grease
Waste grease
Algae
Biodiesel defined by ASTM Specifications:
B5 and lower (ASTM D975)
B6 to B20 (ASTM D7467)
B100 (ASTM D 6751)
Common Nomenclature
B5= 5% biodiesel in diesel fuel B20= 20% biodiesel in diesel fuel
Biodiesel can be blended with diesel fuel in any ratio.
There is no “blend wall” for biodiesel.

• The 1.5 billion gallons of biodiesel produced
in 2013 reduced emission by:
• PM 9,350,000 pounds
• HC 12,690,000 pounds
• CO 104,085,000 pounds

OEM Support
• All major OEMs selling diesel equipment in the U.S. support at least B5 and lower blends, provided they are made with biodiesel meeting ASTM D 6751
• Most OEMs are also recommending use of a BQ-9000 supplier • 10 new OEM statements of B20 support in 2012, 6 in 2013 • Over 78 percent of U.S. manufacturers (39 brands) support B20 or
higher blends in at least some of their equipment; • Nearly 90 percent of the medium- and heavy-duty truck markets
support B20

Performance Benefits of Biodiesel
• Yields the same kind of horsepower, torque, and performance
as diesel fuel
• Naturally Ultra-Low in Sulfur
• <15 ppm
• Enhanced Lubricity
• B5 blend restores lubricity to ULSD
• High Cetane
• 47 min., 55 common
Environmental Benefits of Biodiesel
• Cleaner, Safer Diesel Exhaust Emissions
• Superior Energy Efficiency (captures solar energy)
• Lifecycle Carbon Reduction
• Nontoxic & Biodegradable
• Reduces Wastewater & Hazardous Waste Production
Liquid Fuel is Stored Solar Energy Plants store energy in natural oils.
Nature has pre-assembled long carbon chains.
Annual crops concentrate energy in seed.
Animals store energy in fat.
Liquid fuels are energy-dense,
easily transported, and easily stored.
Oils release energy easily.
Biodiesel stores solar energy.
Plants recycle carbon from the air.
Hydrocarbons (H, C, & O) do not mine nutrients (N, P, & K)
from soil

1998 USDA/NREL 78%
2008 DOE/Argonne 66-94%
2010 CARB 78%
2010 USEPA 85%
2010 DOE/Argonne 89-122%
2010 GHGenius 86%
2012 Univ. Idaho/USDA 81%
GHG Reductions with Biodiesel Blends
•A B20 blend reduces lifecycle GHG emissions of a diesel vehicle by 16%.
•This compliments MPG, PM, and NOx improvements of new diesel vehicles.
•A B5 blend reduces lifecycle GHGs by 4%.
Better For Your Health
• Biodiesel is:
– Nontoxic:
• LD50 =17.4 g/Kg - less toxic than table salt
• Skin irritation less than that of 4% soap and water solution
– Safer to handle: Flash point above 200 Degrees F, Non-Reactive, Non-Corrosive
Biodiesel reduces impact to water resources
Reduces wastewater by 79%
Reduces hazardous waste by 96%
B20 no NOx increase in 49-state USEPA Diesel
B20 no NOx increase in 2010 and later engines
B5 no NOx increase in CARB diesel
• Biodiesel use ramps up as
NOx-neutral engines replace old technology.
• Low blends in use today have no measurable NOx impact.
• Potential future NOx will be mitigated by engine technology.

NOx Impact of Biodiesel in CARB diesel
• CARB mitigating NOx for future increases of biodiesel use.
• No NOx increase w/ current use of biodiesel.
• NOx issue goes away with new diesel engines.
• Combined effect of NOx and PM reduction has no measurable increase in ozone even in
South Coast.
