Presents cutting-edge insights on transforming agricultural waste into renewable energy, sustainable materials, and economic opportunities The urgent need to transition toward sustainable development has propelled agro-waste management to the forefront of global research and policy initiatives. Agricultural residues, once treated as environmental burdens, now offer vast potential as renewable feedstocks for biofuels, compost, and biochar, as well as for driving innovations in the circular economy. Agro-Waste Management and Valorization provides an authoritative and comprehensive overview of the scientific, technological, and economic frameworks required to turn agricultural waste into valuable resources. Through a multidisciplinary lens, the authors examine the chemistry, engineering, and environmental principles that shape modern waste-to-value pathways, while situating these approaches within relevant legislative and policy contexts. The book integrates fundamental concepts, applied research, and real-world case studies to demonstrate how biological and thermochemical conversion processes, waste biorefineries, and digital innovations can advance sustainability goals. Detailed analyses of bio-additives, composting strategies, and algae-based biorefineries highlight the practical applications of waste valorization across diverse agricultural systems. In-depth chapters incorporate techno-economic analyses and life cycle assessments to equip readers with the tools needed to evaluate feasibility and long-term impact. Both synthesizing current knowledge and charting a pathway for future inquiry and technology transfer in the field, Agro-Waste Management and Valorization: Explores advanced bioconversion and thermochemical techniques with detailed process parameters and optimization strategiesHighlights studies of waste-to-energy technologies and their integration into sustainable agricultural systemsAnalyzes international and national policy frameworks shaping agro-waste management and valorizationExamines waste biorefinery and algal biorefinery models with real-world scalability considerationsIncludes techno-economic analysis (TEA) and life cycle assessment (LCA) of key technologiesInvestigates innovative uses of glycerol and biochar, as well as emerging digital tools such as IoT for efficient waste monitoring and processingAgro-Waste Management and Valorization is an essential reference for graduate and postgraduate students in environmental chemistry, chemical engineering, agricultural sciences, and biotechnology, particularly in courses such as Environmental Sustainability, Waste Management, and Renewable Energy Systems. It is equally valuable for researchers, policymakers, and professionals in biotechnological and agricultural industries who are seeking practical and research-based approaches to agro-waste valorization.
