Abstract: Bioethanol is a green fuel that is produced from renewable biological materials such as plant biomass. Our study aims to find out the most efficient and eco-friendly method for producing bioethanol from the feedstock and considers several parameters, including the selection of feedstock, pre-treatment method, enzymatic hydrolysis, fermentation and fractionation step. It is concluded that lignocellulosic biomass is the best material. Agriculture waste such as duckweed and agro-industrial waste can also serve as a good lignocellulose-rich biomass substrate. Duckweed with its low lignin content, low doubling time, and cheap pre-treatment appears to be the most suitable choice for bioethanol production. Genetically modified microorganisms for the production of ethanol from a mixture of sugars and a single stage fermentation using fed-batch process would be preferable. A combination of the above-mentioned processes and materials should provide efficient and low-cost bioethanol production, which would be a significant competitor to fossil fuels.
