1. BIOFUEL

2. What is biofuel?
Liquid fuel produced from plant products
Category: Biodiesel, Bioalcohols, Ethanol,
Coconut seeds
pure vegetable oil, Biogas
Palm seeds
An alternative to petroleum based fuel Pond Algae
Biodiesel feed stocks:
•Palm
•Coconut
•Jatropha curcas
• Rapeseed/ Mustard seed
Rapeseeds Jatropha seeds
•Sunflower
•Corn
•Soybean
•Peanuts
•Algae
•Used restaurant oil
•Animal fats Sunflower seeds Soybean seeds
Corn

3. Biofuels derived
from biomass or
biowaste
biomass : material which is
derived from recently
living organism / obtained
from plants & animals
byproducts

4. 2 methods to form biofuel :
a) Sugar crops and starch are
grown and through process of
fermentation, ethanol is
produced.

5. b) Plants are grown naturally to
produce oil like algae.
- oils are heated to reduce
viscosity, then directly use as fuel
for diesel engines

6. • RENEWABLE SOURCE
(√) BIOFUEL
(X) COAL
(X) PETROLEUM
(X) NUCLEAR FUEL

7. These are some of the agricultural
products grown just for production
of BIOFUELS :
₰ switchgrass , soybeans , corn : USA
₰ sugar cane : BRAZIL
₰ sugar beet & wheat : EUROPE
₰ palm oil : South-East Asia

10. BIODIESEL
Undergoes transesterification
Produced after mixing the biomass with
methanol and sodium hyroxide
Used for car diesel engines

11. VEGETABLE OIL
Generally use for cooking
purpose
Vegetable oil is mainly used for
the production of biodiesel

12. BIOALCOHOLS
Fermentation process
Common type of bioalcohol
whereas butanol and propanol
Butanol is produced using
the process of ABE
fermentation

13. Biogas
Biogas is mainly produced
after the anaerobic digestion
of the organic materials
Biogas produced is very rich in
methane

14. syngas
This is a gas that is produce after
the combined process of
A)gasification
B)combustion
C)pyrolysis

23. A method of solid waste disposal in which
refuse are buried between layers
of dirt so as to fill in or reclaim low-lying
ground.
A site used for or reclaimed by such disposal

30. ADVANTAGES AND
DISADVANTAGES OF BIOMASS

31. •ADVANTAGES
Biomass used as a fuel reduces need for fossil fuels for
the production of heat, steam, and electricity for
residential, industrial and agricultural use.
Biomass is always available and can be produced as a
renewable resource.
Biomass fuel from agriculture wastes maybe a
secondary product that adds value to agricultural crop.
Growing Biomass crops produce oxygen and use up
carbon dioxide.

32. The use of waste materials reduce landfill
disposal and makes more space for everything
else.
Carbon Dioxide which is released when
Biomass fuel is burned, is taken in by plants.
Less money spent on foreign oil

33. •DISADVANTAGES
Agricultural wastes will not be available if the
basic crop is no longer grown.
Additional work is needed in areas such as
harvesting methods .
Land used for energy crops maybe in demand for
other purposes, such as
faming, conservation, housing, resort or agricultural
use.
Some Biomass conversion projects are from animal
wastes and are relatively small and therefore are
limited.

34. Research is needed to reduce the costs
of production of Biomass based fuels.
Its expensive and requires a lot of
resources to convert the raw materials
to an energy source.
Is in some cases is a major cause of
pollution.

35. CONCLUSION
Biofuel production has
lead to :
rural electrification
improving agriculture
job creation
women empowerment
power to local community
