Ethanol production

Part of: Prelims and GS III – Environment; Agriculture 

Context Almost two million tonnes (MT) of sugar were diverted for ethanol production during the last sugar season (October 2020 to September 2021).

About Ethanol and its production 

• Ethanol can be produced from sugarcane, maize, wheat, etc which are having high starch content.
• In India, ethanol is mainly produced from sugarcane molasses by fermentation process.
• Ethanol can be mixed with gasoline to form different blends.
• As the ethanol molecule contains oxygen, it allows the engine to more completely combust the fuel, resulting in fewer emissions and thereby reducing the occurrence of environmental pollution.
• Since ethanol is produced from plants that harness the power of the sun, ethanol is also considered as renewable fuel.
