Ethanol vs. Bioethanol — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on March 27, 2024
Ethanol is a common alcohol used as a fuel, solvent, and in manufacturing, whereas bioethanol is ethanol produced from biomass and is renewable and more environmentally friendly.

Key Differences
Ethanol is a versatile compound utilized in various applications, from being a primary ingredient in alcoholic beverages to serving as a solvent in the pharmaceutical industry. On the other hand, bioethanol specifically refers to ethanol produced through the fermentation of biomass, such as corn and sugarcane, highlighting its renewable nature and contribution to sustainable energy sources.
While ethanol serves as a key component in fuel blends to increase octane levels and improve emissions, bioethanol is particularly emphasized for its role in reducing greenhouse gas emissions when compared to fossil fuels. This environmental benefit is due to bioethanol's production from plants that absorb CO2, a greenhouse gas, during their growth cycle.
In the industrial sector, ethanol is produced both synthetically and through fermentation, using a variety of feedstocks including fossil fuels. Bioethanol, however, is produced exclusively through the biological process of fermenting sugars found in agricultural crops, emphasizing its biobased origin and sustainability.
The global market dynamics for ethanol are influenced by its diverse applications across industries, including fuel, pharmaceuticals, and personal care products. Bioethanol's market, in contrast, is primarily driven by the demand for renewable fuels and government policies aimed at reducing carbon footprints, reflecting its niche within the broader ethanol market.
Ethanol's production and use are well-established worldwide, with significant infrastructure and technology developed over decades. Bioethanol, while benefiting from advancements in fermentation technology, also focuses on innovations in feedstock utilization and efficiency improvements to enhance its competitiveness and environmental credentials.

Ethanol
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic chemical compound. It is a simple alcohol with the chemical formula C2H6O. Its formula can be also written as CH3−CH2−OH or C2H5OH (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor.
Bioethanol
A renewable energy source from biomass.
Bioethanol is produced from sugarcane and corn.
Ethanol

Bioethanol
Ethanol produced by fermenting the sugars in biomass materials such as corn, sugar beets, switchgrass, or agricultural residues, used as a fuel in internal-combustion engines either in pure form or more often as a gasoline additive.
Ethanol
(organic compound) A simple aliphatic alcohol formally derived from ethane by replacing one hydrogen atom with a hydroxyl group: CH3-CH2-OH.
Bioethanol
Ethanol produced, by fermentation of crops, for use as a biofuel.
Ethanol
Specifically, this alcohol as a fuel.
Ethanol
The organic compound C2H5.OH, the common alcohol which is the intoxicating agent in beer, wine, and other fermented and distilled liquors; called also ethyl alcohol. It is used pure or denatured as a solvent or in medicines and colognes and cleaning solutions, or mixed in gasoline as a fuel for automobiles, and as a rocket fuel (as in the V-2 rocket).
Ethanol
The intoxicating agent in fermented and distilled liquors; used pure or denatured as a solvent or in medicines and colognes and cleaning solutions and rocket fuel; proposed as a renewable clean-burning additive to gasoline
