ABSTRACT: Petroleum and other fossil fuel has been the main energy source for a long period of time in human life. Through these energy sources, the world has been a developing and industrializing entity. However, it is agreed that these traditional sources of energy cannot remain forever as they are non-renewable. Many experts predicted that oil production will keep on decreasing, as the present oil wells keep on decreasing and fewer oil reserves are discovered. This led to increasing price of the minerals and eventually makes them economically unsustainable. As such, renewable source of energy has to be sourced. Bioethanol; a renewable energy source is being produced from food materials such as sugar cane, maize etc. However, if these are to be used for energy production, the world will be entering into another crisis as they will be competed for food and energy. Lignocellulosic wastes such as Rice straw, Wheat straw, Corn straw and Bagasse contain same sugar molecules for bioethanol production as such can be used to generate renewable energy using appropriate physical, chemical and biological techniques. This paper aims at exploring the process of bioethanol production from lignocellulosic wastes.
