Union Government is working on a plan to use stubble as a biofuel and manure as part of an effort to deal with stubble burning

What are Biofuels:

  • Hydrocarbon fuel
  • Produced from an organic matter (living or once living material) in a short period of time (days, weeks, or even months)
  • May be
    • Solid: Wood, dried plant material, and manure
    • Liquid: Bioethanol and Biodiesel
    • Gaseous: Biogas


  • 1st generation biofuels
    • Called conventional biofuels
    • Made from things like sugar, starch, or vegetable oil
    • Made from a feedstock that can also be consumed as a human food
  • 2nd generation biofuels
    • Produced from sustainable feedstock
    • No second generation biofuel is also a food crop, though certain food products can become second generation fuels
    • Often called “advanced biofuels.”
  • 3rd generation biofuels
    • Derived from algae
    • Given their own separate class because of their unique production mechanism and their potential to mitigate most of the drawbacks of 1st and 2nd generation biofuels.
  • 4th generation biofuels
    • In the production of these fuels, crops that are genetically engineered to take in high amounts of carbon are grown and harvested as biomass.
    • The crops are then converted into fuel using second generation techniques.
