The Ministry of New and Renewable Energy announced the National Biofuels Policy in 2009 to promote biofuels in India, and the Union Cabinet approved the National Biofuels Policy–2018 to succeed the existing policy from 2009. Biofuels have attracted worldwide attention over the past decade and it is imperative that biofuels be noticed to accelerate developments. It is noticed that the conversion of agricultural waste into 2nd generation ethanol has opened the door to unused resources and has promoted environmental sustainability. The 2nd generation ethanol, made from agricultural residues, offers significant prospective due to the extensive accessibility, abundance and comparatively inexpensive biomass. The use of agricultural waste to produce 2nd generation ethanol is proving to be a substitute source of energy for a narrow range of nonrenewable energy and food crops. Although this process has many challenges and limitations which are discussed in the chapter e.g. biomass transportation and handling, effective pretreatment methods, high costs based on current technologies that enable high efficiency and high process costs. The use of ethanol blended with diesel fuel has recently attracted the attention of many researchers. The usage of 2nd generation ethanol blended in diesel fuels will develop the agricultural commodity markets and create additional returns from 2nd generation ethanol derived from crop residues. The announcement by the Government of India on stringent emission regulations and the increased use of biofuels may lead to the use of 2nd generation ethanol blended with diesel fuel as a marketable fuel. This chapter highlights agricultural waste, its sources and various practices that include the processes undergone to produce 2nd generation ethanol economically, it also provides insight and suggests a renewable alternative fuel for diesel engines which will help in meeting the stringent emission standards.
