Introduction to Chemicals from Biomass, Second Edition presents an overview of the use of biorenewable resources in the 21st century for the manufacture of chemical products, materials and energy. The book demonstrates that biomass is essentially a rich mixture of chemicals and materials and, as such, has a tremendous potential as feedstock for making a wide range of chemicals and materials with applications in industries from pharmaceuticals to furniture. Completely revised and updated to reflect recent developments, this new edition begins with an introduction to the biorefinery concept, followed by chapters addressing the various types of available biomass feedstocks, including waste, and the different pre-treatment and processing technologies being developed to turn these feedstocks into platform chemicals, polymers, materials and energy. The book concludes with a discussion on the policies and strategies being put in place for delivering the so-called Bioeconomy. Introduction to Chemicals from Biomass is a valuable resource for academics, industrial scientists and policy-makers working in the areas of industrial biotechnology, biorenewables, chemical engineering, fine and bulk chemical production, agriculture technologies, plant science, and energy and power generation. We need to reduce our dependence on fossil resources and increasingly derive all the chemicals we take for granted and use in our daily life from biomass – and we must make sure that we do this using green chemistry and sustainable technologies! For more information on the Wiley Series in Renewable Resources, visit www.wiley.com/go/rrs Topics covered include: • The biorefinery concept • Biomass feedstocks • Pre-treatment technologies • Platform molecules from renewable resources • Polymers from bio-based monomers • Biomaterials • Bio-based energy production Praise for the 1st edition: “Drawing on the expertise of the authors the book involves a degree of plant biology and chemical engineering, which illustrates the multidisciplinary nature of the topic beautifully” - Chemistry World

Polymer science faces the challenge of meeting growing market demand for polymers whilst achieving sustainability through environmentally friendly processes. Microwave heating has emerged as a greener technique that accelerates a variety of chemical reactions, including polymerization. Microwave-assisted reactions can be cleaner and more rapid and economic analyses suggest that the cost of curing polymers may be reduced by switching over to the use of microwaves. This book provides comprehensive coverage of microwave-assisted polymerization. The first chapter introduces readers to the theory behind the accelerating effects of microwaves on chemical reactions and covers the types of commercial microwave reactors being used for synthesis and processing of polymers that are available on the market. Subsequent chapters are organised by type of reaction, including radical homo and co-polymerizations, step growth polymerization and peptide synthesis. Importantly, analysis of processes and product properties in comparison with conventional methods is also detailed. This book will be a valuable resource for green chemists and polymer scientists and engineers who want to develop sustainable processes.

Globally we are being confronted by the depletion of many natural resources as a result of unsustainable use and increasing global population. Although the debate on the bioeconomy has gained momentum in recent decades, the interest in certifications and standards for biobased products is still weak. This book aims to fill this gap by promoting a holistic approach, which covers environmental, social and economic sustainability aspects and pushes forward the development of a circular, biobased economy. This book promotes the development of sustainability schemes (including standards, labels and certifications) for the assessment of biobased products, which are fundamental to the establishment of a cutting-edge sustainable bioeconomy. Chemical-related, globally relevant case studies are used throughout the book. The content covers a range of issues from upstream and downstream environmental, techno-economic and social assessment, to crosscutting issues such as indirect land use change (iLUC) and end-of-life options. The chapters included in this book will provide a comprehensive review of recent works on life cycle assessment (LCA), life cycle costing (LCC) and social life cycle assessment (s-LCA) methodologies. An important resource for researchers, industrial professionals and policy makers involved in the bioeconomy.

Sustainable development is now accepted as a necessary goal for achieving societal, economic and environmental objectives. Within this chemistry has a vital role to play. The chemical industry is successful but traditionally success has come at a heavy cost to the environment. The challenge for chemists and others is to develop new products, processes and services that achieve societal, economic and environmental benefits. This requires an approach that reduces the materials and energy intensity of chemical processes and products; minimises the dispersion of harmful chemicals in the environment; maximises the use of renewable resources and extends the durability and recyclability of products in a way that increases industrial competitiveness as well as improve its tarnished image.

Inadequate access to clean water afflicts people throughout the world, and in developing countries any solution to this challenge must be achieved at a low cost and low energy demand. At the same time, the use of chemicals, and subsequent environmental impact must also be reduced. Green and sustainable water remediation is a rapidly growing field of interest to governments and corporations alike, with considerable input from academics, environmental consultants and public interest groups. This book presents a focused set of articles covering a range of topics in the field, examining not only the adoption of natural products for water remediation, but also the synthesis of new materials and emerging clean technologies. Contributors from across the globe (including some "on the ground" in the developing world) present a comprehensive digest in the form of review-style articles highlighting the current thinking and direction in the field. Interested stakeholders from all sectors will find this book invaluable, and postgraduate students of chemical engineering or environmental science will benefit from the real-world applications presented.

Green chemistry has progressed from being a driver for change in the chemical and allied industries to being a critical part of chemical education at all levels. The future chemist must be able to practice their trade in the light of increasing concerns about waste and resources, the safety of chemicals in consumer products, and increasingly restrictive legislation. While there are green chemistry educational resources available including lectures and experiments as well as numerous books on green chemistry and major green chemical technologies, there is no “green equivalent” of a standard organic chemistry textbook Systematically covering a variety of well-known reactions that commonly feature in standard organic textbooks this book supplements and supports the standard organic chemistry texts. It highlights the main sustainability issues of classical and contemporary organic transformations and critically evaluates them within a metric of established Green Chemistry Principles noting where additional efforts are needed to improve their environmental footprint. Written by a team of expert authors with a multinational advisory board, this book is a fantastic resource for advanced undergraduate and postgraduate students worldwide.

A unique guide written for the chemist who is planning to use or is considering the possible use of supported reagents, an application with great growth potential in the near future. Using practical examples of methods of supported reagent analysis, this comprehensive reference source also contains useful references detailing the best techniques to apply to particular problems. The authors discuss the many choices available in the preparation of supported reagents, including loading, support, method of preparation and activation, as well as covering the various analytical techniques to apply to solids. They also use numerous examples of supported reagents and their use in organic synthesis, emphasizing practical aspects. Chemists in catalysis, organic synthesis, analysis and materials science will obtain enough information to make use of these essentially simple but fascinating materials, which in a little over twenty years have matured from academic curiosities to important industrial materials.
