Ethanol is a biofuel that has become an important part of India’s energy reserve. In the past decade or so, the Indian government has implemented various policies to promote the production of ethanol on a large scale, especially as part of its Ethanol Blended Petrol (EBP) program. This initiative aims to reduce the country’s current need for fossil fuels. Along with that the objective of the program also aims at lowering greenhouse gas emissions and supporting the agricultural sector.
Due to the very reason for searching for alternatives to reduce its dependence on fossil fuels, the demand for ethanol has surged significantly. The country is looking to use this immense need for ethanol and meet its renewable energy goals. Ethanol is mainly used as a fuel in the automobile industry and as a raw material in various other industrial applications.
Ethanol is not only used as a biofuel but also finds application in a wide range of industries such as pharmaceuticals, cosmetics, and beverages. India has seen significant growth in ethanol production in recent years due to its demands in industrial places.
How is Ethanol Prepared?
Ethanol is produced through the process of fermentation of sugar-based stocks. This includes sugarcane, corn, or even agricultural waste. The most common method utilized in India involves using molasses of sugarcane. The process of ethanol production involves several key steps:
1. Fermentation: The quantity of sugar present in the feedstock such as sugarcane, is converted into alcohol (essentially ethanol) by using microorganisms such as yeast or even certain bacteria types.
2. Distillation: The by-product will be a mixture of ethanol and water where ethanol is then separated from the water and other impurities through a strict distillation process.
3. Dehydration: The ethanol is purified to remove any persisting impurities. Extra water, if present, is also removed in this process. The anhydrous ethanol is produced at the end of this process. This pure form of ethanol is used for fuel blending.
Ethanol is typically produced in both anhydrous (pure form) and hydrous (with the presence of water content) forms. In India, ethanol is blended with gasoline to reduce carbon emissions and improve energy efficiency in vehicles.

Applications of Ethanol
Since the applications of ethanol are becoming more versatile with almost every company opting for greener fuel to reduce their carbon footprint, the ways in which ethanol can be used are seeing a significant transformation. That includes ethanol inclusion in various supporting industries such as oil-based manufacturing sectors. Ethanol is used across various industries for different purposes. Some of the major applications of ethanol include:
1. Fuel Additive: Throughout the production of Ethanol its main application was that it is blended with gasoline to produce biofuel. This helps reduce carbon emissions and improve fuel efficiency. In India, the government is promoting ethanol-blended fuel to reduce the dependence on fossil fuels and thereby encouraging a sustainable environment.
2. Alcoholic Beverages: Ethanol is the key ingredient in the making of alcoholic beverages like beer, wine, and spirits. It is produced through the fermentation of sugar. The higher demand for alcoholic beverages has also been a vital driving force for the production of ethanol in various countries. Importing and exporting activities of ethanol have an influence on the production of alcohol-based drinks.
3. Industrial Solvent: Ethanol is used as a solvent in the pharmaceutical, cosmetics, and chemical industries. This application is highly famous due to its ability to dissolve a wide range of compounds. As ethanol is separated from water in the heating process, its pure form remains and it acts as an excellent solvent.
4. Disinfectant: Ethanol is widely used in sanitizers and disinfectants for its effectiveness in killing bacteria and viruses. During the COVID-19 pandemic, the need for sanitizers has surged to unforeseen rates, causing an increase in sales of hand sanitizers. One of the key reasons why ethanol is highly in demand is because the need to maintain self-health is prevalent among people today.
5. Chemical Production: Ethanol is a building block in the chemical industry for the production of various products like ethyl acetate, acetic acid, and more. These products are in turn used in different industries as input to generate chemical-based products.
6. Personal Care Products: Ethanol is found in perfumes, lotions, and other personal care products as a solvent and preservative. Ethanol has a wine-like, fruitful smell that can act as both a good solvent and a smelling agent.
7. Renewable Energy: Ethanol is used in the production of biobased chemicals that can be used in the making of various industrial products. Currently, they are used as a renewable source of energy in some regions to reach the green energy objectives of the country.
8. Pharmaceutical Industry: Ethanol is used in the manufacture of medicines and as a sterilizing agent in medical settings. The clinical environment uses ethanol in gigantic amounts. Thus their production especially considering the needs in the healthcare sector must be huge.
