This book offers a comprehensive exploration of the dual challenges of waste management and sustainable energy production. It addresses the growing environmental threats posed by industrial, agricultural, and medical wastes, emphasizing their harmful impacts on air, water, and soil. With a focus on biotechnology, nanomaterials, and molecular approaches, the book highlights innovative methods for remediating pollution while simultaneously generating bioenergy. Special attention is given to agro-wastes, such as fruit and vegetable residues, which serve as promising feedstock for green energy, aligning with circular economy principles.

Topics include bioprocesses for waste-to-energy conversion, bio-based pollutant removal, meta-omics techniques, bionanotechnology for site restoration, and bioeconomy models. By combining theoretical insights with practical applications, the book provides valuable reference material for scientists, researchers, students, and professionals working to achieve a cleaner and more sustainable future. It inspires readers to adopt advanced, eco-friendly technologies for resilient environmental management and energy security.
