Production of Bio-ethanol from Renewable Resources: A Review

Bio-fuels such as bio-ethanol have been found a suitable replacement for fossil fuels in terms of energy and environmental safety. Bioethanol can be produced by sugars, starch, lignocelluloses, and algae. Biomasses containing sugar or starch are the traditional source for commercial biofuel production however, feedstock from lignocelluloses and algae groups still drive the attraction of researchers. It may be due to the variety of available options and their different processing techniques. For commercial production of bio-ethanol, several biomasses have been tried by researchers. This review paper concentrates on an overview of the different types of biomass used for bio-ethanol production
