What is Biodiesel? A renewable substitute for diesel fuel made from animal fats or vegetable oils

Vision of the National Biodiesel Board Improve economics of local communities Increases domestic jobs well beyond ag sector Reduce dependence on petroleum Reduce outflow of $ for imports Shift away from sole reliance on diminishing resource Reduce harmful environmental impact Reduce vehicle emissions Reduce net CO2 Reduce threats to water and ecology

Biodiesel: Advanced Biofuel, Here Now Nationwide Production Biodiesel is produced in every region of the country.

Performance Benefits of Biodiesel Yields the same kind of horsepower, torque, fuel economy 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 7

Co-products of Food Production Protein meal for livestock feed is the primary driver for soybean production Better utilization of the oil coproduct can reduce the price of the protein meal.

Lifecycle Emissions Every unit of fossil energy put into producing biodiesel, yields 5.5 units of usable energy. Biodiesel reduces GHG emission by 85-89%* If we used renewable energy instead of natural gas and electricity to process biodiesel, our GHG reduction could exceed 100% % per USEPA 89% per Argonne National Laboratory 9

Lifecycle Analysis And the Carbon Cycle

200 million years ago: atmospheric CO 2 was 4 to 5 times its present concentration. 500 million years ago: atmospheric CO 2 was 20 times higher that it is today. Life as we know it today did not survive under those conditions.

Early life converted CO 2 to solid carbon. Geologic processes converted that carbon to fossil fuels. It took hundreds of millions of years to permanently sequester this carbon and establish the equilibrium that supports life as we know it.

Burning Fossil Fuels Pumps Carbon Into the Atmosphere The last century has reversed millions of years of carbon sequestration. We are depleting oil reserves while increasing atmospheric CO2.

Carbon Problem Grows Every year Fossil Carbon emitted each year7.3 billion tons Carbon absorbed by plants-2.2 billion tons Carbon absorbed by oceans-1.8 billion tons 1% stored in rocks & sediment-.07 billion tons Net Carbon Accumulation3.2 billion tons

Reducing fossil fuel use is the only way to control CO2. Biofuels are a necessary alternative for liquid fuels and other uses of energy.

Plants take CO2 from the air and energy from the sun Plants store carbon in biomass Biofuels harness biomass and stored solar energy Biofuels Recycle Carbon
