Sustainable biofuels and diverse feedstocks drive an in-depth look at conversion technologies and renewable energy sources from crops to algae. It examines production methods, environmental impacts, economic potential, and policy frameworks to inspire climate-smart innovations and shape future energy strategies. This book provides a detailed and up-to-date exploration of biofuels, their feedstocks, and the technologies driving sustainable energy development. With global concerns around fossil fuel depletion and climate change, the need for renewable, eco-friendly energy sources has never been more urgent. This volume serves as a timely and comprehensive resource on the production, application, and future prospects of biofuels derived from various agricultural and natural sources.

Beginning with a foundational overview of biofuel feedstocks and conversion technologies, the book examines key crops such as maize, sugarcane, sweet sorghum, castor bean, rapeseed, sunflower, oil palm, and jatropha for their bioethanol and biodiesel potential. It also covers tuber crops and cellulosic (2G) resources, along with third-generation (3G) biofuels from microalgae and macroalgae, and advances in fourth-generation (4G) biofuel technologies.

The book offers insightful discussions on tree-borne oilseeds, economic viability, and the policy landscape supporting biofuel development. Real-world case studies and techno-economic analyses highlight the commercial potential of bioenergy crops while addressing environmental concerns, land use efficiency, and sustainability.

Designed for students, researchers, policymakers, and practitioners, this book bridges the gap between agricultural sciences, energy policy, and industrial application. With an interdisciplinary approach, it not only informs but also inspires future innovations in the field of renewable energy and climate-smart agriculture.
