Rethinking Polyester Polyurethanes: Algae Based Renewable, Sustainable, Biodegradable and Recyclable Materials explains how and why bio-based materials, specifically algae, will change the polymer industry. The book provides background on algae, polyurethanes (PUs), and their everyday use. It covers the biology and chemistry behind how and why these materials are engineered to be both biodegradable and, through the process of depolymerization, fully recyclable. Chapters cover Re-evaluating the Sources, Redefining the Analytics, Reformulating Polyester Polyurethanes, and The Future. The latter part of the book describes the landscape of bio-based materials, the eco-consumer, and insights into the industry problem of "greenwashing. This book is a valuable resource for industry professionals who use polyurethanes in the supply chain for manufactured products, those in sales and marketing or regulatory roles who wish to better understand the unique advantages of bio-based materials, and researchers studying R&D of biobased polyurethanes or remediation of microplastics pollution on land and in bodies of fresh and saltwater worldwide. - Builds on the foundation of sustainable, renewable, biodegradable, recyclable microplastics, with lifecycle assessment, techno-economic analysis, and the green premium - Clarifies the true economics—if we were to go back to initial development of the plastics industry, what would we do differently? - Covers the basic science—the knowledge required to effectively communicate the use of materials that are on first examination more expensive, but on closer examination less expensive when environmental consequences are factored

Pyrolysis of Organic Molecules with Applications to Health and Environmental Issues, the 28th volume in the Techniques and Instrumentation in Analytical Chemistry series, gives a systematic and comprehensive description of pyrolysis of non-polymeric organic molecules. Pyrolysis is involved in many practical applications as well as in many common human activities, but harmful compounds can be generated in the process. The study of pyrolysis and of the formation of undesirable compounds as a result of pyrolytic processes is of considerable interest to chemists, chemical engineers, and toxicologists. - Pyrolysis results for compounds not previously studied or reported - Updated information from a large body of results published on pyrolysis of individual compounds or classes of compounds - Information on mechanisms and kinetics of numerous pyrolytic processes

Interest in green chemistry and clean processes has grown so much in recent years that topics such as fluorous biphasic catalysis, metal organic frameworks, and process intensification, which were barely mentioned in the First Edition, have become major areas of research. In addition, government funding has ramped up the development of fuel cells and biofuels. This reflects the evolving focus from pollution remediation to pollution prevention. Copiously illustrated with more than 800 figures, the Third Edition provides an update from the frontiers of the field. It features supplementary exercises at the end of each chapter relevant to the chemical examples introduced in each chapter. Particular attention is paid to a new concluding chapter on the use of green metrics as an objective tool to demonstrate proof of synthesis plan efficiency and to identify where further improvements can be made through fully worked examples relevant to the chemical industry. NEW AND EXPANDED RESEARCH TOPICS Metal-organic frameworks Metrics Solid acids for alkylation of isobutene by butanes Carbon molecular sieves Mixed micro- and mesoporous solids Organocatalysis Process intensification and gas phase enzymatic reactions Hydrogen storage for fuel cells Reactive distillation Catalysts in action on an atomic scale UPDATED AND EXPANDED CURRENT EVENTS TOPICS Industry resistance to inherently safer chemistry Nuclear power Removal of mercury from vaccines Removal of mercury and lead from primary explosives Biofuels Uses for surplus glycerol New hard materials to reduce wear Electronic waste Smart growth The book covers traditional green chemistry topics, including catalysis, benign solvents, and alternative feedstocks. It also discusses relevant but less frequently covered topics with chapters such as "Chemistry of Long Wear" and "Population and the Environment." This coverage highlights the importance of chemistry to everyday life and demonstrates the benefits the expanded exploitation of green chemistry can have for society.

The volume of waste produced by human activity continues to grow, but steps are being taken to mitigate this problem by viewing waste as a resource. Recovering a proportion of waste for re-use immediately reduces the volume of landfill. Furthermore, the scarcity of some elements (such as phosphorous and the rare-earth metals) increases the need for their recovery from waste streams. This volume of Issues in Environmental Science and Technology examines the potential resource available from several waste streams, both domestic and industrial. Opportunities for exploiting waste are discussed, along with their environmental and economic considerations. Landfill remains an unavoidable solution in some circumstances, and the current situation regarding this is also presented. Other chapters focus on mine waste, the recovery of fertilisers, and the growing potential for compost. In keeping with the Issues series, this volume is written with a broad audience in mind. University students and active researches in the field will appreciate the latest research and discussion, while policy makers and members of NGOs will benefit from the wealth of information presented.

Despite recent optimism and global initiatives, the implementation of corporate sustainability programs has been slow at best, with less than a third of global companies having developed a clear business case for their approach to sustainability. Presenting numerous award-winning cases and examples from companies such as Unilever, Patagonia, Tumi, DSM and Umicore alongside original ideas based upon 20 years of consulting experience, this book reveals how to design and implement a stronger sense of focus and move sustainability programs forward. This proven combination of purpose, direction and speed is dubbed “Vectoring”. Based upon practitioner cases and data analysis from the Dow Jones Sustainability Index, Vectoring offers a plain-spoken framework to identify the relative position of companies compared to their peers. The framework and its 4 archetypes deliver insights for practitioners to locate inhibitors and overcome them by providing practical suggestions for process improvements. This includes designing and executing new sustainability programs, embedding the SDGs within company strategy and assessing the impact of sustainability programs on competitiveness and valuation. Offering directions for CFOs to shift companies from integrated reporting to integrated thinking in order to accelerate their sustainability programs, Winning Sustainability Strategies shows how to achieve purpose with profit and how to do well by doing good.

Substantially revising and updating the classic reference in the field, this handbook offers a valuable overview and myriad details on current chemical processes, products, and practices. No other source offers as much data on the chemistry, engineering, economics, and infrastructure of the industry. The Handbook serves a spectrum of individuals, from those who are directly involved in the chemical industry to others in related industries and activities. It provides not only the underlying science and technology for important industry sectors, but also broad coverage of critical supporting topics. Industrial processes and products can be much enhanced through observing the tenets and applying the methodologies found in chapters on Green Engineering and Chemistry (specifically, biomass conversion), Practical Catalysis, and Environmental Measurements; as well as expanded treatment of Safety, chemistry plant security, and Emergency Preparedness. Understanding these factors allows them to be part of the total process and helps achieve optimum results in, for example, process development, review, and modification. Important topics in the energy field, namely nuclear, coal, natural gas, and petroleum, are covered in individual chapters. Other new chapters include energy conversion, energy storage, emerging nanoscience and technology. Updated sections include more material on biomass conversion, as well as three chapters covering biotechnology topics, namely, Industrial Biotechnology, Industrial Enzymes, and Industrial Production of Therapeutic Proteins.
