Materials from renewable resources are receiving increased attention, as leading industries and manufacturers attempt to replace declining petrochemical-based feedstocks with products derived from natural biomass, such as cereal straws. Cereal straws are expected to play an important role in the shift toward a sustainable economy, and a basic knowledge of the composition and structure of cereal straw is the key to using it wisely. Cereal Straw as a Resource for Sustainable Biomaterials and Biofuels: Chemistry, Extractives, Lignins, Hemicelluloses and Cellulose provides an introduction to straw chemistry. Topics discussed include the structure, ultrastructure, and chemical composition of straw; the structure and isolation of extractives from the straw; the three main components of straw: cellulose, hemicelluloses, and lignins; and chemical modifications of straw for industrial applications. This book will be helpful to scientists interested in the areas of natural resource management, environmental chemistry, plant chemistry, material science, polysaccharide chemistry, and lignin chemistry. It will also be of interest to academic and industrial scientists/researchers interested in novel applications of agricultural residues for industrial and/or recycling technologies.

Key Features

  •  Provides the basics of straw composition and the structure of its cell walls

  • Details the procedures required to fractionate straw components to produce chemical derivatives from straw cellulose, hemicelluloses, and lignins

  • Elucidates new techniques for the production of biodegradable materials for the energy sector, chemical industry, and pulp and paper business



Scientists with research interests in the areas of natural resource management, environmental chemistry, plant chemistry, material science, polysaccharide chemistry, lignin chemistry, etc, as well as academic and industrial researchers with an interest in using agricultural residues as novel products for industry and/or recycling technologies
