Biotransformation of Food Waste into Bioenergy: Processes, Innovations, and Environmental Implications is a comprehensive resource that addresses the critical need for sustainable and environmentally responsible processing of food industry wastes into advanced biofuels and bioenergy. The book presents state-of-the-art approaches for sustainable processing of food industry wastes into advanced biofuels, bioenergy, and bioproducts, addressing food waste sources, generation, and characterization, advanced bioconversion technologies, and environmental and economic implications. The book is divided into three parts. Part I, Fundamentals, covers the rising global concern of food waste, its sources, generation, and characterization, as well as methods for measuring, classifying, and disposing of food wastes. It also discusses upcycling food waste to support sustainability, advances in pretreatment methods, and current practices and emerging technologies in managing and repurposing food waste. Part II, Food Waste to Biofuels and Bioenergy, delves into biotechnological pathways for converting food waste into bioproducts, including biohythane, biogas, biohydrogen, bioethanol, biobutanol, aviation fuel, and biodiesel. It also covers microbial and enzymatic engineering, thermochemical conversion, valorization of food wastewater, biorefinery concepts, and biocatalytic-powered valorization. Part III, Trends, Challenges, and Perspectives, addresses the potential, feasibilities, and restrictions of food waste valorization through fermentation processes, environmental impacts and life cycle assessment of food waste management technologies, technical challenges, policy frameworks, and future perspectives. It also explores bioreactor-assisted valorization, advanced modeling approaches, intelligent assessment and management of food waste, and new trends in food waste valorizations through case studies. Biotransformation of Food Waste into Bioenergy: Processes, Innovations, and Environmental Implications is a valuable reference for scientists, engineers, researchers and practitioners involved in the broad field of transforming biomass food waste into bioenergy and bioproducts, and will also be of interest to graduate and post-graduate students.• Presents life cycle assessments and economic evaluations to assess the sustainability and financial viability of converting food waste into biofuels, bioenergy and bioproducts• Covers pretreatment methods and biogas purification techniques, including biological processes, membrane technology, and co-fermentation strategies, highlighting their efficiency and effectiveness in enhancing biofuel quality• Examines how the sustainable conversion of food waste supports the circular economy by integrating advanced production methods, resource optimization, and waste valorization, contributing to environmental sustainability• Provides real-world case studies from different regions showcasing successful food waste management projects, providing practical insights and lessons learned for effective implementation and scaling of food waste-to-biofuel technologies
