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.

Algae play an important ecological role as oxygen producers and carbon sequesters and are the food base for all aquatic life. Algae are economically important as a source of crude oil, food and feed, and pharmaceutical and industrial products. High-value and sustainable products from algae are already economically viable and can be a fundamental driver for fuel production. Algae in the Bioeconomy provides a detailed overview of the chemical composition of algae and shows that an integrated biorefinery approach is necessary for large-scale algae production and conversion, where multiple products are produced. This book serves as a unique compendium of knowledge covering the essential features of algae and their applications. Discusses the structural chemistry and biology of micro- and macroalgal components Describes classification, occurrence, conversion, and production of micro- and macroalgae Offers strategies for optimal use of micro- and macroalgae in the bioeconomy, including regional strategies in the EU, US, China, India, Malaysia, Norway, and Chile Features forewords from international experts offering both a scientific and an economic/strategic viewpoint This book is intended for an interdisciplinary audience in chemical engineering, biotechnology, and environmental science and engineering, promoting research, development, and application of algae as a sustainable resource.

Increasing plastic pollution, particularly in oceans, calls for a fundamental shift towards future-proof plastics throughout the circular economy. In a landmark move in 2022, the United Nations adopted a historic resolution to craft an international legally binding instrument to tackle plastic pollution. In line with this global initiative, Plastics in the Oceans investigates the problem of plastic pollution in oceans, proposes solutions relating to current and advanced materials and technologies, and offers an optimal sustainable strategy to eliminate plastic pollution by 2040. The title: Addresses the entire lifecycle of plastic, from production and design to disposal, and advocates for a comprehensive approach to mitigate plastic pollution. Focuses on primary and secondary microplastics, recognizing their significant impact on marine ecosystems. Explores various alternative materials, including biobased biodegradable polymers, as viable alternatives to conventional plastics. Provides insights into regulatory frameworks pertaining to plastic pollution across major world regions. Elucidates the need for reducing plastic production and enhancing recycling efforts in combating plastic pollution. Suggests strategies aligned with the principles of the 3Rs—reduce, redesign, recycle—to foster the development of sustainable and future-proof plastics. This book is aimed at technical readers in environmental engineering, chemical engineering, and polymer chemistry, as well as general readers interested in scientific solutions to the plastics pollution problem.
