Animal Byproducts and Wool Science: Processing, Utilization, and Sustainable Applications offers an in-depth exploration of the scientific, industrial, and environmental dimensions of byproduct processing and wool technology. Designed for students, researchers, veterinary professionals, livestock entrepreneurs, and sustainability advocates, this book provides a comprehensive understanding of how materials often regarded as waste—such as bones, hides, intestines, feathers, and wool—can be transformed into valuable products through eco-conscious practices.

The first section of the book focuses on the sustainable processing of animal byproducts from slaughterhouses, detailing their potential applications in pharmaceuticals, fertilizers, cosmetics, food ingredients, biofuels, and bioplastics. It emphasizes safe handling, efficient resource use, and the design of modern byproduct utilization facilities with considerations for organic waste management, composting, and energy recovery.

The second section delves into wool science, covering the anatomy, properties, and grading of wool, fur, pelts, and specialty fibers. It outlines the wool value chain—from shearing and sorting to quality assessment and industrial processing—and emphasizes wool’s role in the textile and fashion industries, particularly within the framework of natural fiber sustainability.

With a strong focus on the circular economy, ethical sourcing, and green technologies, the book highlights the value of integrating sustainability into animal product utilization. It is an essential resource for advancing both scientific understanding and industrial best practices in line with global sustainability goals.
