Production of Ethanol from Napier Grass

The production of ethanol from Napier grass is the easiest method. The Indian government declared 20 % ethanol blending into the petrol, so it is very necessary to produce ethanol in the easiest way, efficiently. The increasing demand for renewable and environmentally friendly energy sources has sparked interest in bioethanol as a sustainable alternative to fossil fuels. Napier grass (Pennisetum purpureum), a tropical grass known for its high biomass yield, has emerged as a promising lignocellulosic feedstock for ethanol production. This report provides a comprehensive overview of the process of ethanol production from Napier grass, including biomass preparation, chemical and enzymatic pretreatments, hydrolysis, fermentation, distillation, and ethanol recovery. The study aims to evaluate the viability of Napier grass as a biofuel source and outlines the process in detail, from raw material to final ethanol output.
