The global demand for clean, renewable, and sustainable energy has placed biofuels at the forefront of modern energy research. This book provides a comprehensive exploration of emerging trends, scientific principles, and technological advancements in biomass-based bioenergy production. Bridging fundamental concepts with applied research, it offers a unified perspective on how biological systems—particularly algae, microbes, and lignocellulosic feedstocks—can be engineered and optimized to meet future energy needs.

Beginning with algal biofuels, the book examines utilization strategies, production challenges, and the transformative potential of genetic engineering in enhancing biofuel yields. It further delves into smart energy management, pre-treatment strategies for lignocellulosic materials, and the valorization of agricultural wastes into high-value products such as glycerol, bioethanol, and biohydrogen. The chapters also highlight innovations in microbial biofuel production and the emerging role of biorefineries within a circular economy framework.

Designed to simplify complex biochemical, thermodynamic, and kinetic concepts, this book serves as an essential resource for students, researchers, engineers, and policymakers. It not only presents scientific insights but also practical approaches that support greener, scalable, and economically viable biofuel technologies. By integrating waste management, smart energy systems, and bioprocess optimization, the book contributes to shaping a sustainable and resilient global energy future.
