BIODIESEL FUELS FOR THE FUTURE
Posted June 23, 2008on:
India is the sixth country in the world with a billion population. Our country faces problems in regard to the fuel requirement for increased transportation demand and now imports about 70 % of its petroleum requirement .The petroleum import bill is about 14 billion dollars. The current yearly consumption of diesel oil in India is approximately 40 million tones forming 40 % of the total petroleum products consumption. The potential demand for Biodiesel at 20% blend is estimated at 13.38 million tones per annum by 2012. In the present problematic traditional cultivation, raising of energy plantation to produce Biodiesel, farmers can develop and utilize waste lands and improve incomes, rural labour will have more employment opportunities and soil fertility and condition will improve. Any vegetable oil can be converted in to Biodiesel; however, in India there is no surplus production of edible oil. Therefore, the oil that can be used as Biodiesel has to be non-edible oil.
Produced in abundance and with stand harsh climate, as they would be taken up in wastelands, the most suitable species in this regard are Jatropha and Pongamia. These plants could be grown on wasteland about 80 million hectares of which is available in India. The oil extracted from the seed is used in place of diesel after simple filtration. After further processing this can be used in four wheelers. The seed cake after extraction of oil will be very good organic manure as it contain high nitrogen content. This cake can also be utilized for biogas production. The pruned leaves are used as green leaf manure.
