2. WHAT IS BIO FUEL?
• Bio fuel is a type of fuel whose energy is
derived from biological carbon fixation.
• Bio fuels include fuels derived from biomass
conversion as well as solid biomass and
liquidfuel biomass.
TypES OF BIO FUELS:
1)Bio diesel
2)Bio ethanol
3)Bio gas
4)Bio hydrogen

3.  High yield of oil %.
 Least risk of failure.
 Least cultivation inputs.
 High acceptability of farmers.
 Suitability of oil for diesel.
 Wide adaptability to stress.
 Fast growing &Short rotation.
 Availability of seed materials.
 Least disease occurrence.

BIOFUELS

5. • Neem (Azadirachta indica),
• Karanj (Pongamia pinnata ),
• Meswak (Salvadora species ),
• Mahua (Madhuca indica ),
• Rubber ( Hevea species ),
• Castor (Ricinus communis ),
• Palm oil / Rice bran oil ,
• Jatropha (Jatropha curcas ).
Non edible oil tree species

6. What is Biodiesel?
• Alternative fuel for diesel engines; made from
vegetable oil, animal fat, Algae etc.
• Meets health effect testing (CAA)
• Lower emissions, High flash point (>300F), High
Octane number and excellent lubricity, Safer,
Biodegradable, Essentially non-toxic.
• It effects Biodiversity and Food vs Fuel debates.
• Chemically, biodiesel molecules are mono-alkyl
esters produced usually from triglyceride esters

HYDROCARBON PRODUCING
CROPS
• some plants like Euphorbia lathyris, milk weed
and tree legume produce hydrocarbons which
can be converted into and used as diesel,
called biodiesel.

8. AlgAe And Biodiesel
• Algae Biodiesel is a good
replacement for standard crop
Biodiesels like soy and canola
• Up to 70% of algae biomass is
usable oils
• Algae does not compete for land
and space with other
agricultural crops
• Algae can survive in water of
high salt content and use water
that was previously deemed
unusable

9. • Much of the world uses a system known as the
"B" factor to state the amount of biodiesel in
any fuel mix.
• 100% biodiesel is referred to as B100
• 20% biodiesel, 80% petrodiesel is labeled B20
• 5% biodiesel, 95% petrodiesel is labeled B5
• 2% biodiesel, 98% petrodiesel is labeled B2

10. BIODIESEL : FIRST TRIAL RUN ON TRAIN
 First successful trial run of a superfast passenger
train was conducted on Dec 31, 2009
 Delhi - Amritsar Shatabdi Express used 5% of
biodiesel fuel.
 Railway annual fuel bill = Rs 3400 crores (for Diesel)
 10% mixture with Diesel = reduced
(Rs.300-400 crores /
annum)
 5% substitution is accepted.

11. • Biogas typically refers to a gas
produced by the breakdown of organic
matter in the absence of oxygen.
• It is 50-70% methane.
• Cow dung mixed with water to create
slurry
• Slurry is put into airtight digester
• Methane created and collected
• Jatropha, Neem cakes slurry can also
be used instead of cow dung slurry.
