Bioenergy is derived from different biological resources that are renewable in nature. These are obtained from agricultural byproducts such as wood waste, straw, wood, sugarcane, etc. that need further processing to be converted into a biofuel. The principle of bioenergy lies in the utilization of solar energy trapped in these sources. It has huge potential to reduce the carbon footprint. Although there has been a continuous evolution in technologies required for conversion of biomass into bioenergy, still there is an enormous requirement for further innovation to produce cleaner fuels. This book covers some significant topics such as bioenergy processing technologies, sustainable biorefinery systems, novel breeding and cropping technologies, production and development of energy crops, etc. This book unravels the recent studies in this field. The diverse aspects of bioenergy along with technological progress that have future implications are glanced at in this book. It will help the readers in keeping pace with the rapid changes in this area.
