Is there a possibility of biodiesel being produced without using corn i.e., other silage?

See the links below for types of biofuels including biodiesel that can be produced.

Biofuel production is controversial when it impacts food sources and when the energy it takes to grow and produce the biofuel outweighs the benefits of using less fossil fuels for transportation.See the Guardian article below for more information on that.

Biofuels are transportation fuels such as ethanol and biodiesel that are made from biomass materials. These fuels are usually blended with petroleum fuels (gasoline and diesel fuel), but they can also be used on their own. Using ethanol or biodiesel reduces the consumption of gasoline and diesel fuel made from crude oil, which can reduce the amount of crude oil imported from other countries. Ethanol and biodiesel are also cleaner-burning fuels than pure gasoline and diesel fuel.

What is ethanol?

Ethanol is an alcohol fuel made from the sugars found in grains such as corn, sorghum, and barley.

Other sources of sugars to produce ethanol include

  • Sugar cane
  • Sugar beets
  • Potato skins
  • Rice
  • Yard clippings
  • Tree bark
  • Switchgrass
