Ethanol, a renewable alcohol-based fuel, plays a pivotal role in the global shift toward sustainable energy sources. Derived from food grains like maize, it's recognized for its eco-friendliness and cleaner emissions. Ethanol derived from food grains, such as maize, is often considered high-quality due to the starch content in these grains. Starch-rich feedstocks can result in ethanol with good energy content and purity. As India and the world embrace ethanol production and blending, its significance grows, reducing dependence on fossil fuels and curbing carbon emissions, contributing to a greener and more sustainable future.
