Re: FW: [P2assist] NC State to use Biodiesel on Campus

Thank you for the summary of the biodiesel.  Our county's Fleet Department started using biodiesel about two years ago and I find it such a promising alternative.  I attached Pinellas County Fleet Department's case study to this e-mail.  The biodiesel synopsis is on the bottom of the first page.

Subject: [P2assist] NC State to use Biodiesel on Campus

For Immediate Release

NC State University is eager to announce that beginning March 1, 2003,
all diesel purchased through Fleet Services will be a B-20 blend of
biodiesel.  123 NC State vehicles and pieces of equipment will make the
switch.  Over the next 3 years, the Wolfline busses operated by Connex,
will also make the switch.

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. 

What is B-20?
B-20 is 20% biodiesel and 80% standard diesel.  It is the blend that NC
State will be using.  
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. 
How do biodiesel emissions compare to petroleum diesel?
 Biodiesel is the only alternative fuel to have fully competed the
health effects testing requirement of the Clean Air Act.  The use of
biodiesel in a conventional diesel engine results in substantial
reduction of unburned hydrocarbons, carbon monoxide, and particulate
matter compared to emissions from diesel fuel.  In addition, the exhaust
emissions of sulfur oxides and sulfates, a major component of acid rain,
from biodiesel are essentially eliminated compared to diesel.  
What are the benefits of using biodiesel? 
Biodiesel results in significantly lower emissions of particulate
matter, carbon monoxide, toxic contaminants, sulfur dioxide,
hydrocarbons, visible smoke and noxious odors than petroleum diesel.
Depending on the feed source, biodiesel can result in lower life-cycle
carbon dioxide emissions. 

Emissions reductions achieved by biodiesel as compared to petroleum
Source: http://www.afdc.doe.gov/pdfs/5450.pdf 
Emission	B100	B20   
Carbon Monoxide   	43.2%	12.6%
Hydrocarbons	56.3%	11.0%
Particulates	55.4%	18%
Sulfates	100%	20%
Nitrogen Oxide	+5.8%	+1.2%
Air Toxics	60-90%   	20%
Biodiesel is non-toxic and biodegradable and therefore does not pose a
threat to water and soil resources if B100 is spilled. Producing
biodiesel from restaurant oil or animal processing wastes reduces the
amount of materials overcrowding landfills. Additionally, biodiesel is
one of the safest fuels to use, handle, and store because it does not
produce combustible vapors and has a higher flash point (300 F) than
petroleum diesel. Significant benefits of biodiesel include reducing our
dependence on foreign oil and providing alternative markets for farmers.

Will modifications need to be made to the vehicles or pumping

Will biodiesel cost more?
Yes.  B-20 often averages $0.09 - $0.12 more per gallon.  But a grant
from the Triangle J Council of Governments (TJCOG) to cover 80% of the
increase in cost will make this transition easier.   Many thanks to
TJCOG for this opportunity.
