15 Important Facts about Biodiesel:

What is Biodiesel?

Biodiesel is the name for a variety of ester-based oxygenated fuels made from vegetable oils or animal fats.  The concept of using vegetable oil as a fuel dates back to 1895 when Dr. Rudolf Diesel developed the first diesel engine to run on vegetable oil. Diesel demonstrated his engine at the World Exhibition in Paris in 1900 using peanut oil as fuel.

Properties of Biodiesel

Todays diesel engines require a clean-burning, stable fuel that performs well under a variety of operating conditions. Biodiesel is the only alternative fuel that can be used directly in any existing, unmodified diesel engine. Because it has similar properties to petroleum diesel fuel, biodiesel can be blended in any ratio with petroleum diesel fuel. Many federal and state fleet vehicles in USA are already using biodiesel blends in their existing diesel engines.

The low emissions of biodiesel make it an ideal fuel for use in marine areas, national parks and forests, and heavily polluted cities. Biodiesel has many advantages as a transport fuel. For example, biodiesel can be produced from domestically grown oilseed plants such as canola. Producing biodiesel from domestic crops reduces the Australia's dependence on foreign petroleum, increases agricultural revenue, and creates jobs.

Key Advantages of Biodiesel:

1. Biodiesel is the only alternative fuel in the US to complete EPA Tier I Health Effects Testing under section 211(b) of the Clean Air Act, which provide the most thorough inventory of environmental and human health effects attributes that current technology will allow.

2. Biodiesel is the only alternative fuel that runs in any conventional, unmodified diesel engine. It can be stored anywhere that petroleum diesel fuel is stored.

3. Biodiesel can be used alone or mixed in any ratio with petroleum diesel fuel. The most common blend is a mix of 20% biodiesel with 80% petroleum diesel, or "B20."

4. The lifecycle production and use of biodiesel produces approximately 80% less carbon dioxide emissions, and almost 100% less sulphur dioxide. Combustion of biodiesel alone provides over a 90% reduction in total unburned hydrocarbons, and a 75-90% reduction in aromatic hydrocarbons. Biodiesel further provides significant reductions in particulates and carbon monoxide than petroleum diesel fuel. Biodiesel provides a slight increase or decrease in nitrogen oxides depending on engine family and testing procedures. Based on Ames Mutagenicity tests, biodiesel provides a 90% reduction in cancer risks.

5. Biodiesel is 11% oxygen by weight and contains no sulphur. The use of biodiesel can extend the life of diesel engines because it is more lubricating than petroleum diesel fuel, while fuel consumption, auto ignition, power output, and engine torque are relatively unaffected by biodiesel.

6. Biodiesel is safe to handle and transport because it is as biodegradable as sugar, 10 times less toxic than table salt, and has a high flashpoint of about 125°C compared to petroleum diesel fuel, which has a flash point of 55°C.

7. Biodiesel can be made from domestically produced, renewable oilseed crops such as soybeans, canola, cotton seed and mustard seed.

8. Biodiesel is a proven fuel with over 30 million successful US road miles, and over 20 years of use in Europe.

9. When burned in a diesel engine, biodiesel replaces the exhaust odor of petroleum diesel with the pleasant smell of popcorn or french fries.

10. The Congressional Budget Office, and Department of Defense, US Department of Agriculture, and others have determined that biodiesel is the low cost alternative fuel option for fleets to meet requirements of the Energy Policy Act.

Biodiesel Impact

An important factor that is not usually considered when calculating the costs and benefits of industrial feedstock materials is the macroeconomic effect associated with domestically produced, renewable energy sources. Economic benefits of a biodiesel industry in the US would include value added to the feedstock (oilseeds or animal fats), an increased number of manufacturing jobs, an increased tax base from plant operations and income taxes, investments in plant and equipment, improvement of our trade balance, and reductions in health care costs due to improved air quality and greenhouse gas mitigation.

Biodiesel has positive impacts on the state economy. An Iowa State University study concluded that three economic benefits would accrue to state from biodiesel. First, biodiesel expands demand for soybean oil, causing processors to pay more for soybeans, In addition, soybean farmers near the biodiesel plant would receive slightly higher prices for soybeans; and third, the presence of a facility that creates energy from soybeans would add value to the state's industrial and income base.

Dr. Hayes concluded that, "If the state of Iowa were to mandate the use of a 20 percent biodiesel blend in its state vehicle fleet where feasible, the total additional cost of this policy would range from $400,000 to $500,000. If it could be shown that this policy would result in a new five million gallon biodiesel plant in the state, then the policy would create more new tax revenues than it would cost and would clearly be in the best interest of the state."

Biodiesel has positive implications for production agriculture. A 1996 economic study published by the USDA Office of Energy predicted that a modest, sustained annual market for biodiesel of 100 million gallons in the US would contribute approximately seven cents to the price of each bushel of soybeans produced in the US. Based on last years harvested crop, the increase could have resulted in more than $168 million directly to the use of biodiesel.

Biodiesel has a positive impact on the US balance of trade. A 1998 biodiesel lifecycle study jointly sponsored by the US Department of Energy and the US Department of Agriculture concluded that increased use of biodiesel and biodiesel blended fuels such as B20 would substantially benefit our economy. The report concluded that national spending to import petroleum sends significant amounts of dollars out of our domestic economy every year. Biodiesel offers the potential to shift this spending from foreign imports to domestically produced energy. The report notes: "With its ability to be used directly in existing diesel engines, biodiesel offers the immediate potential to reduce our demand for petroleum in the transportation sector."

Biodiesel contributes jobs to the local economy. Economic work conducted at the University of Missouri estimated the benefits of producing biodiesel in a metropolitan region. This study concluded that 100 million gallons of biodiesel production could generate an estimated $8.34 million increase in personal income and over 6,000 additional temporary or permanent jobs for the metropolitan region.

Biodiesel Usage

Basic Terminology: Biodiesel is the pure, or 100 percent, biodiesel fuel.

It is referred to as B100 or "neat" fuel.

A biodiesel blend is pure biodiesel blended with petrodiesel. Biodiesel blends are referred to as Bxx. The xx indicates the amount of biodiesel the blend (i.e., a B20 blend is 20 percent biodiesel and 80 percent petrodiesel).

Ensure the neat biodiesel fuel meets the biodiesel specification for pure biodiesel before blending with petrodiesel.  The specification for biodiesel is designed to ensure that consumers will not experience operational problems from the fuels use. Make sure that biodiesel meets this specification and that the fuel supplier will warrant this fact. Quality fuel will provide the consumer with improved air quality and enhanced operability. Poor quality fuel will create operability problems and increased maintenance activity. Purchase only qualified fuel from a reputable source.

Check fuel filters on the vehicles and in the delivery system frequently upon initial biodiesel use and change them as necessary.  Biodiesel and biodiesel blends have excellent solvent properties. In some cases the use of petrodiesel, especially #2 petrodiesel (has not been observed with #1), leaves a deposit in the bottom of fueling lines, tanks, and delivery systems over time. The use of biodiesel can dissolve this sediment and result in the need to change filters more frequently when first using biodiesel until the whole system has been cleaned of the deposits left by the petrodiesel. This same phenomenon has been observed when switching from #2 to #1 petrodiesel.

Be aware of biodiesel's freezing properties and take precautions as with #2 petrodiesel use in cold weather.  A 20 percent blend of biodiesel with petrodiesel raises the freezing properties approximately 3° to 5° F (pour point, cloud point, cold filter plugging point). In most cases, this has not been an issue. Twenty percent biodiesel blends have been used in the upper Wisconsin area and in Iowa during -25° F weather with no problems. Solutions to biodiesel winter operability problems are the same solutions used with conventional #2 petrodiesel (use a pour point depressant, blend with #1diesel, use engine block or fuel filter heaters on the engine, store the vehicles near or in a building, etc.). Neat biodiesel will begin to freeze at about 25° F and, if used or stored on site, will need to be kept in an area that will not get below that temperature. Most underground tanks are around 50° F and are not a problem.

Wipe painted surfaces immediately when using biodiesel. As mentioned earlier, biodiesel is a good solvent. Biodiesel can, if left on a painted surface long enough, dissolve certain types of paints. Therefore it is recommended to wipe any biodiesel or biodiesel blend spills from painted surfaces immediately.

Store biodiesel or biodiesel blend soaked rags in a safety can to avoid spontaneous combustion.  Biodiesel soaked rags should be stored in a safety can or dried individually to avoid the potential for spontaneous combustion. Biodiesel is made from vegetable oils and animal fats which can oxidize and degrade over time. The oxidizing process can produce heat. In certain environments, for example, a pile of oil soaked rags can become concentrated enough to result in a spontaneous fire. (Note: Paul has a hole in seat of his van to testify to this!!!)

Use the biodiesel within one year.  All fuels, including #2 and #1 petrodiesel, have a shelf life. This is also true with biodiesel and biodiesel blends. Industry experts recommend that biodiesel be used within one year to ensure that the quality of the fuel is maintained. Storage time does not impact biodiesel distribution given biodiesels production logistics. Biodiesel is generally not stored for long periods of time. Production levels and rates are established to meet demand (similar to "just in time" inventory methods). This is an advantage enjoyed by renewable fuels, like biodiesel, that cannot be shared by its fossil fuel counterparts.

The Biodiesel Association of Australia is available to answer additional questions regarding the transition to biodiesel fuel use. Please do not hesitate to call and ask your questions.

Emissions

Biodiesel is the first and only alternative fuel to have a complete evaluation of emission results and potential health effects submitted to the U.S. Environmental Protection Agency (EPA) under the Clean Air Act Section 211(b). These programs include the most stringent emissions testing protocols ever required by EPA for certification of fuels or fuel additives in the US. The data gathered through these tests complete the most thorough inventory of the environmental and human health effects attributes that current technology will allow. A survey of the results is provided in the table below.

The overall ozone (smog) forming potential of biodiesel is less than diesel fuel. The ozone forming potential of the speciated hydrocarbon emissions was nearly 50 percent less than that measured for diesel fuel.

Sulphur emissions are essentially eliminated with pure biodiesel. The exhaust emissions of sulphur oxides and sulfates (major components of acid rain) from biodiesel were essentially eliminated compared to sulphur oxides and sulphates from diesel.

Criteria pollutants are reduced with biodiesel use. The use of biodiesel in an unmodified Cummins N14 diesel engine resulted in substantial reductions of unburned hydrocarbons, carbon monoxide, and particulate matter. Emissions of nitrogen oxides were slightly increased.

Carbon Monoxide -- The exhaust emissions of carbon monoxide (a poisonous gas) from biodiesel were 50 percent lower than carbon monoxide emissions from diesel.

Particulate Matter -- Breathing particulate has been shown to be a human health hazard. The exhaust emissions of particulate matter from biodiesel were 30 percent lower than overall particulate matter emissions from diesel.

Hydrocarbons -- The exhaust emissions of total hydrocarbons (a contributing factor in the localized formation of smog and ozone) were 93 percent lower for biodiesel than diesel fuel.

Nitrogen Oxides -- NOx emissions from biodiesel increase or decrease depending on the engine family and testing procedures. NOx emissions (a contributing factor in the localized formation of smog and ozone) from pure (100%) biodiesel increased in this test by 13 percent. However, biodiesels lack of sulphur allows the use of NOx control technologies that cannot be used with conventional diesel. So, biodiesel NOx emissions can be effectively managed and efficiently eliminated as a concern of the fuels use.

Biodiesel reduces the health risks associated with petroleum diesel. Biodiesel emissions showed decreased levels of PAH and nitrited PAH compounds which have been identified as potential cancer causing compounds. In the recent testing, PAH compounds were reduced by 75 to 85 percent, with the exception of benzo(a)anthracene, which was reduced by roughly 50 percent. Targeted nPAH compounds were also reduced dramatically with biodiesel fuel, with 2-nitrofluorene and 1-nitropyrene reduced by 90 percent, and the rest of the nPAH compounds reduced to only trace levels.

Environmental & Safety Information

Fuel Displacement

Vehicles that operate on 20 percent blends of biodiesel blended with 80 percent conventional diesel (B20) will, on average, displace more than twice as much petroleum as conventional light-duty passenger vehicles already covered under the Energy Policy Act (EPACT).

Diesel engines used by medium and heavy duty government fleets consume significantly greater quantities of fuel than the light duty passenger vehicles that comprise the majority of the current EPACT fleets. The diesel engine vehicle portion of these fleets will be the primary market for B20.

The chart below illustrates the displacement potential of B20. All of the figures on vehicle miles travelled, miles per gallon, and total fuel usage are provided by the US Department of Energys Energy Information Administration publication: Alternatives to Traditional Transportation Fuels.

VMT = Vehicle Miles Traveled MPG = Miles Per Gallon

As the chart shows, the key to total displacement is not the percentage blend level of the fuel, rather it is a function of the fuel blend level, fuel economy of the vehicles and the annual use of that vehicle by the fleet.

On average, B20 vehicles will displace more petroleum than existing light-duty EPACT passenger vehicles operating on higher blend levels because medium and heavy duty diesel engine vehicles consume substantially greater volumes of fuel than light-duty passenger vehicles.

Performance

Successful alternative fuels fulfil environmental and energy security needs without sacrificing operating performance. Operationally, biodiesel performs very similar to low sulphur diesel in terms of power, torque, and fuel without major modification of engines or infrastructure.

Biodiesel offers similar power to diesel fuel. One of the major advantages of biodiesel is the fact that it can be used in existing engines and fuel injection equipment with little impact to operating performance. Biodiesel has a higher cetane number than U.S. diesel fuel. In over 15 million miles of in-field demonstrations biodiesel showed similar fuel consumption, horsepower, torque, and haulage rates as conventional diesel fuel.

Biodiesel provides significant lubricity improvement over petroleum diesel fuel. Lubricity results of biodiesel and petroleum diesel using industry test methods indicate that there is a marked improvement in lubricity when biodiesel is added to conventional diesel fuel. Even biodiesel levels below 1 percent can provide up to a 30 percent increase in lubricity.

Compatibility of biodiesel with engine components. In general, biodiesel will soften and degrade certain types of elastomers and natural rubber compounds over time. Using high percent blends can impact fuel system components (primarily fuel hoses and fuel pump seals), that contain elastomer compounds incompatible with biodiesel. Manufacturers recommend that natural or butyl rubbers not be allowed to come in contact with pure biodiesel. Biodiesel will lead to degradation of these materials over time, although the effect is lessened with biodiesel blends. If a fuel system does contain these materials and users wish to fuel with pure biodiesel, replacement with compatible elastomers is recommended. The recent switch to low sulphur diesel fuel has caused many OEMs to switch to components suitable for use with biodiesel, but users should contact their OEM for specific information.

Biodiesel in cold weather. Cold weather can cloud and even gel any diesel fuel, including biodiesel. Users of a 20 percent biodiesel blend will experience a decrease of the cold flow properties (cold filter plugging point, cloud point, pour point) of approximately 3 to 5° Fahrenheit. Precautions beyond those already employed for petroleum diesel are not needed for fueling with 20 percent blends. However, neat (100 percent) biodiesel will gell faster than petrodiesel in cold weather operations. Solutions for winter operability with biodiesel are much the same as that for low-sulphur #2 diesel (i.e., blending with #1 diesel, utilization of fuel heaters, and storage of the vehicle in or near a building).

Production

The production of biodiesel, or alkyl esters, is well known. There are three basic routes to ester production from oils and fats:

• Base catalyzed transesterification of the oil with alcohol.
• Direct acid catalyzed esterification of the oil with methanol.
• Conversion of the oil to fatty acids, and then to Alkyl esters with acid catalysis.

The majority of the alkyl esters produced today are done with the base catalyzed reaction because it is the most economic for several reasons:

• Low temperature (150 F) and pressure (20 psi) processing.
• High conversion (98%) with minimal side reactions and reaction time.
• Direct conversion to methyl ester with no intermediate steps.
• Exotic materials of construction are not necessary.

The general process is depicted below. A fat or oil is reacted with an alcohol, like methanol, in the presence of a catalyst to produce glycerine and methyl esters or biodiesel. The methanol is charged in excess to assist in quick conversion and recovered for reuse. The catalyst is usually sodium or potassium hydroxide which has already been mixed with the methanol.

Biodiesel 2000

Indicators that the Biodiesel Industry is Growing and Poised to be a Significant Contributor to the U.S. Alternative Fuels Market

Recent achievement of three major long-term objectives. Because of the following 3 long-term achievements, biodiesel has become one of the fastest (if not the fastest) growing alternative fuels in the country.

1. Health Effects: In May 2000, biodiesel became the only alternative fuel in the country to have successfully completed the EPAs Tier I and Tier II Health Effects testing under Section 211(b) of the Clean Air Act. The Tier I testing conclusively demonstrated biodiesels significant reductions in most currently regulated emissions as well as most unregulated emissionsespecially those associated with cancer and lung disease. Tier II testing demonstrated biodiesels non-toxic effect on health.

1. EPACT: Effective November 1998, B20, a blend of 20% biodiesel and 80% petroleum diesel, was approved by Congress as an EPAct (Energy Policy Act of 1992) compliance strategy. The legislation allowed EPAct fleets to meet their alternative fuel vehicle purchase requirements simply by buying 450 gallons of pure biodiesel and burning it in new or existing diesel vehicles in at least a 20% blend with diesel fuel. The Congressional Budget Office and the Department of Defence have confirmed that the biodiesel option is the lowest cost alternative fuel option for meeting the Federal Governments EPACT compliance requirements.

1. ASTM: In December 1998, the American Society of Testing and Materials (ASTM) issued a provisional specification (PS 121) for biodiesel fuel. ASTM is the premier standard-setting organization for fuels and additives in the U.S. The EPA has adopted the ASTM standard and state divisions of weights and measures currently are considering its adoption. This development was crucial in standardizing fuel quality for biodiesel in the U.S. market.

Current Industry Progress and Initiatives:

Biodiesel Use Is Increasing Significantly. In March 1999, three major fleets were known to be using B20 for EPAct compliance. By October 1999, that number had increased to over 25 and includes such fleets as the Ohio Department of Transportation, U.S. Postal Service, General Services Administration, Alabama Power and the U.S. Department of Agriculture. That is more than a 700% increase in biodiesel users in six months. New fleets are committing every day.

Low Blend Premium Diesel Development: Since 1997, seven companies have released premium additive packages containing biodiesel in which biodiesel is a major marketing aspect of the product. In the summer of 1999, Kochthe second largest privately owned company in the US behind Cargill-launched a new premium diesel fuel product, US SoyField Diesel, which is now in more than 20 terminals in the Midwest and expanding. Also in 1999, Country Energy (the Farmland/Cenex petroleum joint venture) launched SoyMaster, its proprietary premium diesel containing biodiesel, in four terminals in the Midwest. These petroleum companies, and others are evaluating the expansion of their product lines to include B20 and market the alternative fuel to their network of customers through their terminal and distributor systems.

Biodiesel Supplier Base is Increasing: In 1996 there were two companies who were registered biodiesel suppliers. In 1999 there are 13 companies who have invested millions of private dollars into the development of the biodiesel manufacturing plants and industry development activities. In fact, a new, less expensive continuous biodiesel process was patented last summer with plans to build several additional plants around the country. The number of inquiries received by NBB staff and consultants for biodiesel manufacturing plants has skyrocketed over the last 12 months.

Political and Public Support is Increasing Significantly: Over the last 12 months, there has been a significant amount of increased political support for biodiesel. Biodiesel has been hampered compared to other alternative fuels, because public policies were not in place to allow the quantification of the significant energy security, agricultural, and environmental benefits of the fuel. Biodiesel is now being included in major state and nation-wide legislative efforts, which are providing a mechanism to quantify the benefits of the fuel and are making it a cost-competitive option for achieving many of the nation and state-wide goals. Major biodiesel initiatives have recently passed in Arizona, Ohio, New Jersey, Delaware, and Iowa.  Bipartisan federal Legislation was introduced in May 2000 by Senators Daschle and Lugar which would require a percentage of biodiesel in all low-sulphur diesel fuel as a renewable lubricity additive.  And environmentalists have finally begun to recognize the environmental benefits of the fuel- biodiesel was used to power Earth Day 2000.

Presidential Executive Orders: On August 12, 1999, President Clinton signed Executive Order 13134, Developing and Promoting Biobased Products and Bioenergy, which calls for the expanded use of bio-based fuels such as biodiesel. Furthermore, on September 14, 1998, the President signed Executive Order 13101, Greening the Government Through Waste Prevention, Recycling, and Federal Acquisition, which gives preference to bio-based products for federal government procurement. Finally, on April 22, the president signed Executive Order 13149 which increases the governments targets for displacing petroleum.

Military: The National Biodiesel Board just entered into a Cooperative Research and Development Agreement (CRADA) with the Tank, Automotive and Armament Command (TAACOM) of the U.S. Army to assist them in their effort to incorporate biodiesel into the procurement provisions for the military.

The Defense Logistics Agency (DLA) is streamlining the biodiesel procurement process for both the military and individual federal agencies.

The Department of Defense has issued guidance to all branches of the military for biodiesel use that is favorable to the purchase of the fuel.

Biodiesel blends have been included in the 21^st Century Truck Initiative, being spearheaded by TACOM and the National Automotive Center as a leading alternative fuel for heavy-duty trucks because other alternatives to fossil fuels are not able to deliver the power and performance demanded by the heavy-duty sector.

OEMs: Ford and Chrysler have begun biodiesel research initiatives, with Fords efforts being the most advanced. Ford is conducting independent compatibility testing in anticipation of providing diesel engines certified to operate on biodiesel. Chrysler has included biodiesel in its compatibility specifications. Most major diesel engine manufacturers have affirmed that use of B20 in their equipment will not void their warranty and are actively working with industry on research and development activities. Moreover, the Fuel Injection Equipment manufacturers have issued letters recognizing biodiesels significant role as a renewable lubricity additive.

Future Market Dynamics Show Promise: Increasing pressure is being put on the petroleum industry to reduce sulphur levels and increase cetane number in diesel fuel. EPA and other air quality groups continue to increase pressure to reduce the amount of compounds in diesel exhaust which have the potential to cause cancer and lung disease. Furthermore, global warming and green house gases will continue to gain attention. Biodiesel provides benefits in all these areas, which will further increase the fuels economic competitiveness. Moreover, biodiesel offers fleet managers an immediate and seamless ability to transform their entire diesel fleet into a cleaner burning alternative fuel fleet, without any capital investment. 

Health Effects Testing

HISTORY

In June 2000, representatives of the U.S. Congress announced that biodiesel had become the first and only alternative fuel to have successfully completed the Tier I and Tier II Health Effects testing requirements of the Clean Air Act Amendments of 1990.  The soybean industry invested more than two million dollars and four years into the health effects testing program with the goal of setting biodiesel apart from other alternative fuels and increasing consumer confidence in biodiesel.

TESTING

The first tier of health effects testing was conducted by Southwest Research Institute and involved a detailed analysis of biodiesel emissions.  Tier II was conducted by Lovelace Respiratory Research Institute, where a 90-day sub-chronic inhalation study of biodiesel exhaust with specific health assessments was completed.

RESULTS

Results of the health effects testing concluded that biodiesel is non-toxic and biodegradable, posing no threat to human health.  Also among the findings of biodiesel emissions compared to petroleum diesel emissions:

• The overall ozone (smog) forming potential of exhaust emissions from biodiesel is 50% less.

• The exhaust emissions of carbon monoxide (a poisonous gas and a contributing factor in the localized formation of smog and ozone) from biodiesel are 50% lower.

• The exhaust emissions of particulate matter (recognized as a contributing factor in the respiratory disease) from biodiesel are 30% lower.

• The exhaust emissions of sulphur oxides and sulphates (major components of acid rain) from biodiesel are complete eliminated.

• The exhaust emissions of hydrocarbons (a contributing factor in the localized formation of smog and ozone) are 95% lower.

• The exhaust emissions for aromatic compounds known as PAH and NPAH compounds (suspected of causing cancer) are substantially reduced for biodiesel compared to diesel.  Most PAH compounds were reduced by 75% to 85%.  All NPAH compounds were reduced by at least 90%. 

SIGNIFICANCE

The health effects testing results provide conclusive scientific evidence using the most sophisticated technology available to validate the existing body of testing data.  The comprehensive body of biodiesel data serves to demonstrate the significant benefits of biodiesel to the environment and to public health.  This will lead to increase consumer confidence and increased use of biodiesel.  Since the majority of biodiesel is made from soybean oil, a promising new market is materializing for soybeans.

National Impacts from Increased Biodiesel Usage 

A 1998 biodiesel lifeyclcle study jointly sponsored by the U.S. Department of Energy and the U.S. Department of Agriculture concluded that increased use of biodiesel would benefit our national economy.  Increased biodiesel production would also result in significant economic benefits to state economies as well as agricultural producers.

According to economic modeling conducted by the Food and Agricultural Policy Research Institute, (FAPRI), 70 million gallons of annual demand for biodiesel could add $0.10 to $0.18 per bushel to the price of soybeans.

An analysis conducted by the USDA Economic Economic Research Service estimates that 100 million gallons of biodiesel demand would increase soybean oil prices by 14%.

USDA forecasts that ending stocks of soybean oil in 2000-01 will be 1.85 billion pounds.  Soybean meal demand is forecasted to increase more than soybean oil demand.

Oilseed industry experts estimate an additional four billion gallons of biodiesel feedstock supply could be available through expanded soybean acreage, increased utilization of oilseed crops and higher oil soybeans.

Under current economic conditions, increased in soybean prices will result in decreased federal outlays under the soybean marketing loan program.

The utilization of biodiesel could have immediate impacts on the economy that would increase increased farm income, increased economic activity and corresponding increases to the local tax base, utilization of surplus soybean oil, and decreased federal outlays under the soybean marketing loan program.  However, the biodiesel industry is currently not eligible for policy incentives enjoyed by other segments of the fuels market that would increase biodiesel sales and further market development.

• Until the early 1970's, the US was self sufficient in crude oil production.  However, imports of crude have been increasing at an accelerating rate due to decreasing domestic production and increasing energy needs.  Petroleum imports now account for more than half of our total usage, and make up the single largest component of our trade deficit.  

• A 2000 GAO report documented specific petroleum tax incentives that range from about $330 million for the expensing of tertiary injectants (1980-2000) to about $82 billion for certain cost depletion deductions (1968-2000).

The same GAO report indicated that ethanol fuel tax incentives ranged from $198 million for alcohol fuel tax credits (1980-2000) to about $11 billion for the excise tax exemption for alcohol fuels (1979-2000).

Although the tax incentives provided to the ethanol industry are a fraction of those provided to the petroleum industry, ethanol's favourable tax treatment has been critical in the development of ethanol into a two billion gallon per year industry.  To date, the biodiesel industry has never received any favorable tax or subsidy treatment, and is at a significant disadvantage relative to petroleum.  In fact, the US Congress is currently considering legislation that would provide further incentives to domestically produced petroleum, but would not apply to domestically produced biodiesel.  Inclusion of biodiesel into a comprehensive energy policy that promotes domestically produced renewable fuels could have a significant impact on the development of the biodiesel market, at a relatively low cost to US consumers or taxpayers.

Policy options such as a national renewable standard for diesel fuel would provide significant benefits to the economy.  In May 2000, EPA proposed a limit on sulphur of 15 ppm maximum for on-highway diesel fuel by 2007.  This is a reduction of over 95% from the current limit of 500 ppm.  Removing the sulphur from diesel fuel will reduce fuel lubricity, harming engine life.  Biodiesel improves lubricity at very low percentages.  Biodiesel could be included as a low level blending component in diesel fuel as a means to improve fuel lubricity while meeting other policy objectives.  The Energy Information Administration reports that the total US distillate market in 1998 was over 55 billion gallons and 'on-highway' represented the largest component of this use at over 30 billion gallons.

Inclusion of biodiesel in on-road diesel fuel at a level of 1% for lubricity purposes would result in the following:

• 300 million gallons of biodiesel demand. 
  
• Utilization of the oil from more than 214 million bushels of soybeans (over 2.2 billion pounds of soybean oil).
  
• Add a minimum of 30¢ to the value of a bushel of soybeans, based on economic analyses conducted by USDA-ERS and FAPRI.
  
• Add more than $800 million to gross farm income and decrease federal outlays under the soybean marketing loan program in similar amounts.
  
• Potentially reduce fleet operating costs through increased equipment life.
  

The biodiesel industry is currently reviewing policy options such as tax incentives, relief of EPACT credit restrictions, as well as the inclusion of biodiesel in the national diesel fuel pool that would further the development of the biodiesel market, level the playing field in the alternative fuels marketplace, and lead to national economic benefits.

Economic activity from an activity from an industry can be categorized into direct, indirect, and induced impacts.  Direct impacts are those changes in output or income that can be directly attributed to the industry.  Secondary impacts (indirect and induced) result from subsequent rounds of spending and re-spending by consumers and businesses.  The National Biodiesel Board will conduct a macroeconomic study in spring 2001 to quantify direct and secondary economic impacts, employment, balance of trade, and increased level of economic activity and corresponding state and local tax revenue that result from increased biodiesel usage.

Common Questions:

What is biodiesel?
Biodiesel is the name of a clean burning alternative fuel, produced from domestic, renewable resources. Biodiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend. It can be used in compression-ignition (diesel) engines with little or no modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics.

How is biodiesel made?
Biodiesel is made through a chemical process called transesterification whereby the glycerin is separated from the fat or vegetable oil. The process leaves behind two products -- methyl esters (the chemical name for biodiesel) and glycerin (a valuable byproduct usually sold to be used in soaps and other products).
 

Is Biodiesel the same thing as raw vegetable oil?
No! Fuel-grade biodiesel must be produced to strict industry specifications (ASTM D6751) in order to insure proper performance. Biodiesel is the only alternative fuel to have fully completed the health effects testing requirements of the 1990 Clean Air Act Amendments. Biodiesel that meets ASTM D6751 and is legally registered with the Environmental Protection Agency is a legal motor fuel for sale and distribution. Raw vegetable oil cannot meet biodiesel fuel specifications, it is not registered with the EPA, and it is not a legal motor fuel.

For entities seeking to adopt a definition of biodiesel for purposes such as federal or state statute, state or national divisions of weights and measures, or for any other purpose, the official definition consistent with other federal and state laws and Original Equipment Manufacturer (OEM) guidelines is as follows:

Biodiesel is defined as mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats which conform to ASTM D6751 specifications for use in diesel engines. Biodiesel refers to the pure fuel before blending with diesel fuel. Biodiesel blends are denoted as, "BXX" with "XX" representing the percentage of biodiesel contained in the blend (ie: B20 is 20% biodiesel, 80% petroleum diesel).

Why should I use biodiesel?
Biodiesel is better for the environment because it is made from renewable resources and has lower emissions compared to petroleum diesel. It is less toxic than table salt and biodegrades as fast as sugar. Since it is made in the USA from renewable resources such as soybeans, its use decreases our dependence on foreign oil and contributes to our own economy.

How it helps the Enviroment:
Current mood: determined

Environment:

*Biodiesel is a renewable, biodegradable, cleaner-burning fuel. Unlike other fuel additives, biodiesel poses minimal risk to water quality.

*A 100% biodiesel blend lowers carbon monoxide (CO) emissions by 44 percent, particulate matter emissions by 40 percent and sulfate emissions by 100 percent.
 
*B20 lowers carbon monoxide (CO) emissions by 9 percent, particulate matter emissions by 8 percent and sulfate emissions by 20 percent. When B20 is used along with an oxidation catalyst, it reduces particulate matter by 45 percent, carbon monoxide by 41 percent and total hydrocarbons by 65 percent.
 
*The ozone forming potential of the speciated hydrocarbon emissions for biodiesel was nearly 50 percent less than that measured for diesel fuel.
 
*Biodiesel reduces air toxins by up to 90 percent.
 
*Biodiesel has the highest energy balance of any fuel. For every one unit of fossil energy needed to produce biodiesel, 3.2 units of energy are gained.
 
*Does not contribute to sulfur dioxide emissions
