This edited book provides knowledge about hemicelluloses biorefinery approaching production life cycle, circular economy, and valorization by obtaining value-added bioproducts and bioenergy. A special focus is dedicated to chemical and biochemical compounds produced from the hemicelluloses derivatives platform. Hemicelluloses are polysaccharides located into plant cell wall, with diverse chemical structures and properties. It is the second most spread organic polymer on nature and found in vast lignocellulosic materials from agro and industrial wastes, therefore, hemicelluloses are considered as abundant and renewable raw material/feedstock. Biorefinery concept contributes to hemicelluloses production associated with biomass industrial processes. Hemicelluloses are alternative sources of sugars for renewable fuels and as platform for chemicals production. This book reviews chemical processes for sugar production and degradation, obtaining of intermediate and final products, and challenges for pentose fermentation. Aspects of hemicelluloses chain chemical and enzymatic modifications are presented with focus on physicochemical properties improvement for bioplastic and biomaterial approaches. Hemicelluloses are presented as sources for advanced materials in biomedical and pharmaceutical uses, and as hydrogel for chemical and medicine deliveries. An interdisciplinary approach is needed to cover all the processes involving hemicelluloses, its conversion into final and intermediate value-added compounds, and bioenergy production. Covering this context, this book is of interest to teachers, students, researchers, and scientists dedicated to biomass valorization. This book is a knowledge source of basic aspects to advanced processing and application for graduate students, particularly. Besides, the book serves as additional reading material for undergraduate students (from different courses) with a deep interest in biomass and waste conversion, valorization, and chemical products from hemicelluloses

In order to successfully compete as a sustainable energy source, the value of biomass must be maximized through the production of valuable co-products in the biorefinery. Specialty chemicals and other biobased products can be extracted from biomass prior to or after the conversion process, thus increasing the overall profitability and sustainability of the biorefinery. Biorefinery Co-Products highlights various co-products that are present in biomass prior to and after processing, describes strategies for their extraction , and presents examples of bioenergy feedstocks that contain high value products. Topics covered include: Bioactive compounds from woody biomass Phytochemicals from sugar cane, citrus waste and algae Valuable products from corn and other oil seed crops Proteins from forages Enhancing the value of existing biomass processing streams Aimed at academic researchers, professionals and specialists in the bioenergy industry, Biorefinery Co-Products is an essential text for all scientists and engineers working on the efficient separation, purification and manufacture of value-added biorefinery co-products.
