Explore this authoritative guide to transforming the silk industry written by two experts in biopolymers and materials science

Sustainable Uses of Byproducts from Silk Processing delivers a detailed treatment of the properties and potential applications of silk sources, by-products, and waste. The book describes the composition, structure, processability, and potential applications of all of the different kinds of silk by-products. Highly relevant to those working in mulberry cultivation, silkworm rearing, and silk processing, the distinguished authors offer information on how to transform silk by-products into new materials, energy, fuel, fibers, composites, food, cosmetics, and feed.

Using a valorisation approach to the silk protein sericin and its by-products and taking an application-oriented view of materials sources and wastes in the silk industry. Implementation of these techniques promises to further industries as diverse as cancer treatment, pharmaceuticals, nutraceuticals, and environmental cleanup.

Readers will also benefit from the inclusion of:

• A thorough introduction to sericin, including its structure and properties, how to process it, and its various applications
• An exploration of mulberry leaves, stems, and fruits, including their composition and properties, processing, and non-feed applications
• Discussions of the various uses of silkworm pupae, including food and feed, pupae oil properties and applications, biodiesel, byproducts of biodiesel, and the extraction of chitin and proteins from the pupae shell
• An examination of the applications of silkworm litter Perfect for protein chemists, biotechnologists, cosmetics industry professionals, and materials scientists, Sustainable Uses of Byproducts from Silk Processing will also earn a place in the libraries of polymer and cosmetic chemists who seek a one-stop reference for current and emerging sustainability practices in the silk industry.
