Rethinking Polyester Polyurethanes by Anonim Pdf

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

Introduction to Green Chemistry by John Andraos,Albert S. Matlack Pdf

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.

Winning Sustainability Strategies by Benoit Leleux,Jan van der Kaaij Pdf

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.

Biopolymers and Biotech Admixtures for Eco-Efficient Construction Materials by Fernando Pacheco-Torgal,Volodymyr Ivanov,Niranjan Karak,Henk Jonkers Pdf

Since 1930 more than 100,000 new chemical compounds have been developed and insufficient information exists on the health assessment of 95 percent of these chemicals in which a relevant percentage are used in construction products. For instance Portland cement concrete, the most used material on the Planet (10.000 million tons/year that in the next 40 years will increase around 100 %) currently used in around 15% of total concrete production contains chemicals used to modify their properties, either in the fresh or hardened state. Biopolymers are materials that are developed from natural resources. They reduce dependence on fossil fuels and reduce carbon dioxide emissions. There is a worldwide demand to replace petroleum-based materials with renewable resources. Currently bio-admixtures represent just a small fraction of the chemical admixtures market (around 20%) but with environmental awareness for constituents in construction materials generally growing (the Construction Products Regulation is being enforced in Europe since 2013), the trend towards bio-admixtures is expected to continue. This book provides an updated state-of-the-art review on biopolymers and their influence and use as admixtures in the development of eco-efficient construction materials. Provides essential knowledge for researchers and producers working on the development of biopolymer-modified construction materials Discusses the various types of biopolymers currently available, their different production techniques, their use as bio-admixtures in concretes and mortars and applications in other areas of civil engineering such as soil stability, wood preservation, adhesives and coatings All contributions are made from leading researchers, who have intensive involvement in the design and use of biopolymers in construction materials
