Biofuels and Bioenergy: Biorefinery and Circular Bioeconomy Approaches covers the latest developments in biorefinery approaches for the production of biofuels like bioethanol, biobutanol, and biooil from lignocellulosic biomass, catalytic conversion of biooil into biofuels, biodiesel from non-edible vegetable oils, and biodiesel from microbial and macroalgal lipids. The book also covers biorefinery approaches for a circular bioeconomy and technoeconomic analysis of biofuels production. This book provides comprehensive information on biorefinery approaches for biofuels production for academicians, researchers, scientist and practicing engineers. This valuable reference also includes recent advancements in the utilization of biomass for bioenergy production and discusses the role of artificial intelligence to improvise process modelling and development.
