Is Biodiesel the same thing as raw vegetable oil?
Biodiesel is produced from any fat or oil such as soybean oil, through a refinery
process called transesterification. This process is a reaction of the oil with an
alcohol to remove the glycerin, which is a by-product of biodiesel production.
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, and
is not a legal motor fuel that meets the diesel fuel specifications of ASTM D975.
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%
Is biodiesel used as a pure fuel or is it blended with petroleum diesel?
Biodiesel can be used as a pure fuel or blended with petroleum in any
percentage. B20 (a blend of 20 percent by volume biodiesel with 80
percent by volume petroleum diesel) has demonstrated significant
environmental benefits with a minimum increase in cost for fleet operations
and other consumers.
How do biodiesel emissions compare to petroleum diesel?
Biodiesel is the only alternative fuel to have fully completed the health effects
testing requirements of the Clean Air Act. The use of biodiesel in a
conventional diesel engine not equipped with new diesel aftertreatment
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 (major components of acid
rain) from biodiesel are essentially eliminated compared to higher sulfur
Of the major exhaust pollutants, both unburned hydrocarbons and nitrogen
oxides are ozone or smog forming precursors. The use of biodiesel in diesel
engines not equipped with new diesel aftertreatment results in a substantial
reduction of unburned hydrocarbons. Emissions of nitrogen oxides are either
slightly reduced or slightly increased depending on the duty cycle of the
engine and testing methods used. Based on engine testing, using the most
stringent emissions testing protocols
required by EPA for certification of fuels or fuel additives in the US, the overall
ozone forming potential of the speciated hydrocarbon emissions from
biodiesel was nearly 50 percent less than that measured for diesel fuel. New
Technology Diesel Engines (i.e. those with PM traps and SCR technology
required for on-road applications in the US after 2010) reduce emissions of
BOTH PM and NOx with B20 over 90% than 2004 model year and make
NTDEs as clean or cleaner than either gasoline or natural gas fueled
engines. And use of low carbon B20 in NTDEs make them the clean, green
technology of the future.
Does biodiesel cost more than other alternative fuels?
When reviewing the high costs associated with other alternative fuel systems,
many fleet managers have determined biodiesel is their least-cost-strategy to
comply with state and federal regulations. Use of biodiesel does not require
major engine modifications. That means operators keep their fleets, their
spare parts inventories, their refueling stations and their skilled mechanics.
The only thing that changes is air quality.
Can I use biodiesel in my existing diesel engine?
Biodiesel can be operated in any diesel engine with little or no modification to
the engine or the fuel system. Our product is glyceride free so no clogging is
done on the engines and it runs cleaner than petro-diesel as well.
Is biodiesel more costly than petroleum diesel?
Our biodiesel is more denser than petroleum diesel. It has a density of
860-900 gram per meter cube thus in one liter more biodiesel will get filled
and it falls in the GST slab of 12% so it will cost much less than petroleum
Is biodiesel explosive?
NO, biodiesel is a non- explosive fuel and is completely non-
hazardous; this has been confirmed by the Bombay High Court.
Its flashpoint is 101 degree centigrade which is much high than
petroleum fuels and that makes is non- explosive.
Can biodiesel help mitigate “global warming”?
A 1998 biodiesel lifecycle study, jointly sponsored by the US Department of
Energy and the US Department of Agriculture, concluded biodiesel reduces
net CO² emissions by 78 percent compared to petroleum diesel. This is due to
biodiesel’s closed carbon cycle. The CO² released into the atmosphere when
biodiesel is burned is recycled by growing plants, which are later processed
into fuel..Is biodiesel safer than petroleum diesel? Scientific research confirms
that biodiesel exhaust has a less harmful impact on human health than
petroleum diesel fuel. Biodiesel emissions have decreased levels of polycyclic
aromatic hydrocarbons (PAH) and nitrited PAH compounds that have been
identified as potential cancer causing compounds. Test results indicate 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.
