    • Biofuel with particular focus on Jatropha curcas as biodiesel
      • Dr. Nandita Singh
      • Scientist
      • National Botanical Research Institute (Council for Scientific & Industrial Research) Lucknow (India)
    • Increase in worldwide energy consumption
    • Biofuel
      • obtained from agricultural feed stocks
      • form of energy that can be easily transported and stored, thus tradable
      • environmentally friendly products
    • Three pillars for Biofuel production
    • Liquid biofuels
      • Alcohol fuels : Ethanol and Methanol
      • Vegetable oils: Derived from plant seeds
      • India ranks sixth in terms of energy demands (3.5% of world’s commercial energy)
      • Demand for energy: growing by 4.8 %
      • Diesel consumption: 40 % of energy
      • Demand for diesel: 40 million tons
      • Road transport : 75 %
      Biodiesel in India National Scenario
    • “ Bio-Diesel” refers to the neat ethyl or methyl esters of vegetable oils Biodiesel is a domestically produced renewable liquid fuel that can be manufactured from the oils and fats of plants. It contains no petroleum and can be blended at any level

    • Motivation for Research Since the introduction of diesel engine, Rudolph Diesel (1895) intended to burn modified vegetable oil for development of agriculture . It is only now that we are developing biodiesel for this purpose.
    • Biodiesel for Energy Vegetable Oil Degummification Esterification Removal of water Separation of Glycerine Filter Washings BIO OIL BIO DIESEL
    • Concern for biodiesel ?
      • The world over there is a quest for looking for fossil fuel alternatives:
        • Environmental concerns
        • Economic concerns
        • Reducing fossil fuel reserves
        • Strategic concerns
        • Indigenous production
    • Environmental Motivations No Sulphur or aromatic compounds Safer to breathe Reduced emissions in 3 of the 4 regulated categories: total unburned HC, CO, SPM Promotes more vegetation (C fix) Non toxic and biodegradable
    • Economical Motivations Provides investment in innovations Reduces subsidies New job creation: production, manufacturing, processing, construction, distribution, marketing Import substitution Protects over-dependence on limited sources of fuels
    • Industrial Motivations Increased use will decrease deficit by reducing imports Scope for cleaner technologies Operators use clean fuel with less health problems Links agriculture to energy Storage and transport need little or no modification
    • Government Motivations Energy independence gives strength to countries Biodiesel meets international standards for clean S free diesel Fuel standards for use of renewable energy Incentives for alternate and clean fuel
    • Scientific Motivations Challenge to develop biodiesel at competitive price Develop alternative protocols and tools Develop clean catalysts Reduce cost of lipase technology Achieve environment standards
        • Biodiesel reduces carbon dioxide exhaust emissions by up to 80%.
        • Biodiesel produces 100% less SOx than petroleum.
        • Biodiesel reduces exhaust smoke (particulates) emissions by up to 75% so the usual black cloud associated with a diesel engine can be eliminated.
        • The smell of the biodiesel exhaust is far more pleasant .
      Why biodiesel?
        • Biodiesel is much easier to handle and does not cause cracking or redness.
        • Biodiesel is much less dangerous to put in vehicle fuel tank as its flash point is ± 150°C (300°F) as opposed to petroleum diesel ± 70°C (150°F).
        • Biodiesel degrades about 4 times faster than petroleum diesel after spillage, with most of a spill broken down after just 28 days.
      • Biodiesel provides significant lubricity improvement over petroleum diesel fuel so engines last longer, with the right additives engine performance can also be enhanced
      • Various countries have set their targets:
        • USA to use B20 to B100
        • India to start with B5
        • Brazil to go for B2 to B3
        • Philippines look for B10
    • Indian Initiatives
      • National Mission on Biodiesel has been launched by GOI
      • State Governments designated special authorities/bodies to manage
      • Ministry of Petroleum and Natural Gas notified biodiesel purchase policy
      • Government Institutes are working on technology and promotion
      • Public and private sectors are working on processing and end use
      • Proposed Biodiesel Program in India
      • 2005-2007: Demonstration phase
      • 2007-2010: Expansion – Self sustaining

    • Jatropha curcas Biodiesel in India
      • It is an exotic plant for India and is species native to Mexico and Central America. In India, it is believed to have been introduced by Portugues navigators in the 16 th century.
        • Common Names: Ratanjyot, Purging net, physic nut.
        • Botanical Name : Jatropha curcas
        • Family : Euphorbiaceae
        • Availability : Throughout India (mostly in dry/tropical areas)
        • Features : Small tree or shrub, (3-5 m in height), smooth greasy bark which exudes whitish colored, watery latex when cut and large green to pale green leaves
        • (deciduous), alternative but apically crowded
        • Gestation period : Less than one year (minimum amongst all the tree borne oilseeds)
        • Productive life : 30-35 years.
    • Why Jatropha ?
      • India cannot afford edible vegetable oils
      • We don’t have waste vegetable oil
      • Jatropha can grow in wastelands
      • This is not grazed or browsed
      • It is a shrub and yields fruits in three to four years
    • - High yield of oil % -Least risks 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 material -Least disease occurrence Selection of biofuel tree Jatropha curcas
    •  
    • The land to grow ?
      • Country has nearly 63 million ha of wasteland.
      • Nearly 33 million ha committed for tree plantation
      • Current target is 1 million ha
      • Farmer land, Panchayat land, spoiled, mined sites, underutilized land.
    • Wasteland that can be available for Jatropha Plantation Source: Dr. J. Parikh, IRADE

    • Technologies for mass production of Jatropha curcas
      • Protocols for macro-propagation (from cuttings) and micropropagation (tissue culture)
    • CLONAL PROPAGATION OF JATROPHA
      • Criteria for selection of elite germplasm:
      • Mother plant with annual yield of 3-4 kg fruits/plant.
      • Plants with 35% or more seed oil content.
      • Healthy and disease free plant.
      • Propagation by cuttings in Polybags/Root trainers/Open beds
      • Six to ten inch long cuttings of selected plants are planted in sterile medium ( vermiculite or sand).
      • Cuttings are raised in high-tech nurseries with controlled environmental conditions of temperature and humidity to initiate callus formation.
      • After development of sufficient roots the cuttings are transplanted in net houses in sand beds for hardening.
      • Finally the rooted mature cuttings are transferred in polybags with soil and sand mixture in the ratio of 2:1.
    • DEMONSTRATION PLANTATION OF JATROPHA CURCAS To create public awareness and unused and marginal land utilization demonstration plantation of J. curcas were carried out on total 290 hectares in collaboration with U.P. Government, Railways (NR & NER), Industries (Birla, Tata NTPC), CSIR labs (HRDC, Gaziabad, ITRC), MNRE (SEC, Gwalpahari, Gurgaon).
