Bioethanol is one of the most promising biofuel nowadays, considered it is feasible, sustainable and it is alternative to fossil fuels today. Bioethanol is a volatile and flammable liquid produced through microbial fermentation process. Ethanol is an important solvent and used in chemical feed stock, food and Pharmaceutical industries. Bioethanol reduce the greenhouse gas emissions from transport and other industries. The use of edible plants for biofuels production has recently been of great concern because they compete with food materials. This is an attempt to investigate the viability of sourcing bioethanol from a readily available neem and drumstick leaves. The population of human being is increasing on the average worldwide, hence the demand for energy source increases. In order to avoid these foreseen worrisome, lignocelluloses biomass should be utilized in the production of bio-ethanol and biofuels in general. It is apparent that current fuel bioethanol production from grain-based feedstock is not favorable as it may lead to food shortage to the teaming world populace. This showed that the neem tree leaves and drumstick leaves, made of lignocellulose materials, contain some appreciable percentage of sugar that can be fermented to produce ethanol. Immobilizing the yeast with cheap supporting materials is another strategy to optimize the production process in less cost manner. . Since the large quantities of agro waste are available from plantations, their disposal can be a problem. Therefore, lignocellulose pretreatment and the yeast fermentation technology are still an area of research interest for the second generation fuel production. This showed that the neem tree leaves and drumstick leaves, made of lignocellulose materials, contain some appreciable percentage of sugar that can be fermented to produce ethanol.
