Waste Biomass to Alternative Fuels explores innovative microbial conversion technologies that offer sustainable solutions for energy production from waste biomass, addressing the urgent need for environmentally friendly alternatives to fossil fuels. The world’s increasing population and dependency on available fossil fuels has created a need for environmental sustainability. This need calls for innovative products that offer alternative sustainable solutions with less environmental impact. Waste biomass is a cheap renewable resource for biofuels and can be produced sustainably utilizing various biotechnological and biochemical tools. Waste Biomass to Alternative Fuels introduces microbial conversion technologies to recover energy and fuel from plant-based non-edible biomass and other organic wastes. This book serves as a platform to recognize breakthrough research for understanding the physicochemical properties of biomass, available conversion technologies, and advanced engineering for large-scale biomass processing using microbial biomass. New developments and approaches in biomass processing and characterization, conversion technologies, biofuel upgrading, and utilization are discussed. Waste Biomass to Alternative Fuels seeks to provide information on recent advances in the field of biotechnology, catalysis, bioprocess engineering, microbial fuel cells for environmentally friendly production of clean energy, and fine chemicals.
