FIRST USE OF PEANUT OIL IN
1895 BY DR RUDOLF DIESEL
•
• “The use of vegetable
oils for engine fuels
may seem insignificant
today. But such oils
may become in course
of time as important as
petroleum and the coal
tar products of the
present time."
(1858 – 1913)

WORLD EXPERIENCE ON
BIODIESEL
BIODIESEL IN EUROPE
•Biodiesel has been produced on an industrial scale in EU
since 1992, largely in response to positive signals from the EU
institutions.
•In 2001, it is estimated that some twenty plants produced
around 1 million tonnes, mainly in
•Austria,
•Belgium,
•France,
•Germany,
•Italy,
•Sweden.

INDIA HAS TROPICAL ADVANTAGE
ENORMOUS WASTE LANDS & CHEAP FARM LABOUR
BIODIESEL IN INDIA CAN BE SUCCESS STORY
US RAILROAD BIODIESEL







Sierra Railroad in California, oldest company
First to use biodiesel as fuel
1500 locos to be converted
Need 30 million gallon of Biofuels/Year
3.5 lac acres of land farm
3000 additional jobs
Shall meet EPA norms for 2006
RAIL ROAD TEST PROGRAM ON
BIODIESEL (1999)
 4000 HP (2984 KW) gas turbine powered
passenger
locomotive
 Several Biofuels tested (REE, SME, etc.)
 Turbine maintenance cost compared
 Energy content, compatibilities, emission, cost compared
to diesel
 Emission data studies
 Cost/Km/Unit energy (power) calculated
 Biodiesel holds future in railroad applications
 Remarkable reduction in emission ; Report at www.nrbp.org
BIODIESEL AND ECONOMY
•
An increase of $1 per barrel of crude oil prices adds $425 million to our oil
import bill
•
Oil import constitutes a major part of our trade deficit and has an
enormous impact on our economy and creation of new jobs
•
The US dept of Energy estimates that each $billion of trade deficit costs
the US 27,000 jobs
•
Developing a strong market for biodiesel would have tremendous
economic benefits
•
Investments in biodiesel technology may ensure that we have
transportation fuel options and we will not be so vulnerable
THE INDIAN SCENE
•
Annual growth rate ~6% compared to world average of 2%
•
Oil pool deficit & Subsidies Rs 16,000 crores , Rs 18,440 crores (1996-97)
•
Current per capita usage of petroleum is absymmaly low (0.1 ton/year)
against 4.0 in Germany or 1.5 tons in Malaysia
•
Even Malaysia’s figure would be beyond our paying capacity
•
Our domestic production would meet only 33% of demand at the end of
10th plan and only 27% by 2010-11
•
INVESTMENT IN BIOFUELS MAKE STRONG ECONOMIC SENSE
CAN BIODIESEL WORK IN INDIA?
•
India with just 2.4% of global area supports more than 16% of the human
population and 17% of the cattle population
•
India is one of the largest importers of edible oil
•
Where do we find the oil for biodiesel?
•
A sustainable source of vegetable oil is to be found before we can think of
biodiesel
JATROPHA MAY BE THE ANSWER?
•
•
According to the Economic Survey (1995-96), Govt of India, of the
cultivable land area about 100-150 million hectares are classified as waste
or degraded land
Jatropha (Jatropha curcas, Ratanjyot, wild castor) thrives on any type of
soil
–
–
–
–
–
–
–
Needs minimal inputs or management
Has no insect ,pests& not browsed by cattle or sheep
Can survive long periods of drought
Propagation is easy
Yield from the 3rd year onwards and continues for 25-30 years
25% oil from seeds by expelling; 30% by solvent extraction
The meal after extraction an excellent organic manure (38% protein, N:P:K ratio
2.7:1.2:1)
Jatropha Plantation
Study by Agro-Forestry Federation – Maharashtra (1991)
•
•
•
•
Jatropha is a hardy plant.
Well adopted to arid, semi-arid conditions.
Low fertility and moisture demand.
Grow on stony, shallow or even calcareous
soil.
• Propagated through seed or cuttings.
• Tolerate to scanty to heavy rainfall.
Jatropha Plantation
• 5-6Kg seed / hectare, 2500 plants / hectare
• EXPECTED YIELDS

BIODIESEL FROM JATROPHA
•
IF
– 10 MILLION HECATRES OF WASTE LAND IS BROUGHT UNDER
JATROPHA CULTIVATION
– Can yield 15 million tons of seed (@1.5 Tons / Hectare )
– 4.0 million tons of oil
– An equivalent amount of biodiesel, almost one tenth requirement of
diesel in the country
– Enormous employment generation potential in rural areas
• If only 1 person/family is employed per 5 hectares for jatropha cultivation,
additional 2 million new jobs
• 200 new extraction units of 250 tpd capacity to crush the seeds
– 11 Million tons of excellent organic manure
– 0.4 million tons of technical grade glycerol
Effect on Rural Economy
• Seed price Rs. 4/Kg.
• Seed yield 3000Kg / hectare.
• 5 hectare plantation / family.
• 60,000 Rs / year income.
Additionally :
• Waste lands converted to productive national assets.
• Creation of jobs in downstream processing.
• GAINFUL employment in rural sector.
• Contribution to national energy pool.
