Chitin is the second most abundant natural polymer in the world after cellulose, mainly derived from the food waste of shrimp and crabs. Chitosan is the most important derivative of chitin. Thanks to their biodegradability, non-toxicity, biocompatibility, bioactivity, and versatile chemical and physical properties, chitin and chitosan derivatives are used in a wide variety of applications, including water treatment, cosmetics and toiletries, food and beverages, healthcare/medical, and agrochemicals. Chitin and Chitosans in the Bioeconomy covers all major aspects of chitin and chitosan, including structure, biosynthesis, biodegradation, properties of chitin and derivatives, applications, and market. It offers a special focus on the bioeconomy, which is the renewable segment of the circular economy. Describes the structure, biosynthesis, and biodegradation of chitin and chitosan Covers chitin- and chitosan-based products Details valorization of these materials Presents information on shell biorefineries Chitin and Chitosans in the Bioeconomy serves as a reference for polymer scientists and engineers and is also accessible to economists and advanced students.

Biomass is the physical basis of the bioeconomy, the renewable segment of the circular economy, and as a CO2-neutral part of the carbon cycle, biomass is an efficient carbon sink. Demand for biomass is increasing worldwide because of its advantages in replacing fossil-based materials and fuels, which presents the challenge of reconciling this increased demand with the sustainable management of ecosystems, including forests and crops. This reference book discusses the role of biomass in the bioeconomy and focuses on the European Union and the United States, the first two regions to develop a bioeconomy strategy with an obvious effect on the bioeconomy developments in the rest of the world. Significant developments in other areas of the world are addressed. Features: Provides strategies for optimal use of biomass in the bioeconomy Defines and details sources, production, and chemical composition of biomass Describes conversion, uses, and sustainability of biomass Biomass in the Bioeconomy: Focus on the EU and US will appeal to an interdisciplinary audience of readers working in the fields of chemical and environmental engineering.
