A handbook of applied biopolymer technology: synthesis   Publication : [S.l.] Royal Society of Chemistry 2011 . 500 p. , Scientists are conducting active research in different fields of engineering, science and technology by adopting the Green Chemistry Principles and methodologies to devise new processes, with a view to help protect and ultimately save the environment from further anthropogenic interruptions and damage. With this in mind, the book provides an up-to-date, coherently written and objectively presented set of chapters from eminent international researchers who are actively involved in academic and technological research in the synthesis, (bio)degradation, testing and applications of biodegradable polymers and biopolymers. This pool of the latest ideas, recent research and technological progress, together with a high level of thinking with a comprehensive perspective, makes the emerging field of biodegradable polymer science and engineering (or bio-based polymers) linked to environmental sustainability, the essence of this key publication. The handbook consists of chapters written and contributed by international experts from academia who are world leaders in research and technology in sustainability and biopolymer and biodegradable polymer synthesis, characterisation, testing and use. The book highlights the following areas: green polymers; biopolymers and bionanocomposites; biodegradable and injectable polymers; biodegradable polyesters; synthesis and physical properties; discovery and characterization of biopolymers; degradable bioelastomers, lactic acid based biodegradable polymers; enzymatic degradation of biodegradable polymers; biodegradation of polymers in the composting environment; recent development in biodegradable polymers; research and applications and biodegradable foams. The book is aimed at technical, research-orientated and marketing people in industry, universities and institutions. It will also be of value to the worldwide public interested in sustainability issues and biopolymer development as well as others interested in the practical means that are being used to reduce the environmental impacts of chemical processes and products, to further eco-efficiency, and to advance the utilization of renewable resources for a bio-based production and supplier chain. Readers will gain a comprehensive and consolidated overview of the immense potential and ongoing research in bio-based and biodegradable polymer science, engineering and technology to make the world greener. 14 cm.

Advanced oil crop biorefineries   Publication : [S.l.] Royal Society of Chemistry 2012 . 325 p. , In Europe, the main oil-rich crops are sunflower, rapeseed and olive which are grown primarily for food. This book discusses how to convert this whole crop into energy (fuels, power and heat), food and bioproducts (chemicals and/or materials), whilst making optimal use of the by-products generated during farming/harvesting, primary processing (oil extraction and refining) and secondary processing (transesterification). The resulting processes are more economically competitive and the business margin for oil and biodiesel manufacturers is improved. Previously, oil crops have been the main point of focus but many of the technologies used are applicable to a wide variety of raw materials. For example, cellulose from rapeseed straw can be converted to levulinic acid but the same technology could be applied to cellulose from wheat straw or wood. Significant effort is now being devoted to '2nd generation' raw materials such as ligno-cellulose which avoid direct competition with food sources. This volume integrates these developments with existing plant oil supply chains and combines biochemical and thermochemical processes to form integrated biorefinery schemes. Two unique features of the book are the information on LCA of biorefinery schemes and the surveys showing where traditional industries could be affected by new biorefinery developments. Energy and cost calculations for the key biorefinery processes and are also included revealing that some are surprisingly profitable and could offer significant global benefits. Other topics covered include: novel farming and harvesting methods, efficient extraction of plant oils, producing biodiesel without glycerol, extraction of high value chemicals from agricultural by-products, anaerobic digestion potential of agricultural by-products, use of proteins to yield amino acids, economics and life cycle analysis, stakeholder surveys, and policy scenarios. The book is of interest to academics working in relevant areas of chemistry, biology, materials, engineering, economics and policy studies. Those working in the EU farming industry will also find it relevant to their business. 24 cm. Date : 2012 Disponibilité : Exemplaires disponibles: La bibliothèque des sciences de l'ingénieur (1),
Alternative solvents for green chemistry par Kerton, Francesca M. Publication : Cambridge Royal Society of Chemistry 2009 . 226 p. , Conventional solvents can be hazardous in terms of toxicity, flammability and waste generation. Consequently, alternative solvents now form a substantial part of green chemistry. This book covers the latest developments in this growing field as well as some key areas that have been overlooked in previous literature. Solvents are important in many areas of chemistry so the author has adopted a general approach encompassing of a wide range of solvents. As part of the Green Chemistry Series, examples are used that tie in with the 12 principles of green chemistry such as atom efficient reactions in benign solvents, processing of renewable chemicals and materials in green solvents. 24 cm.

Transportation biofuels novel pathways for the production of ethanol par Hoogendoorn, Alwin. Publication : [S.l.] Royal Society of Chemistry 2010 . 208 p. , Current world fossil oil production is struggling to meet demand and may even show a decline after 2010. It is therefore necessary to develop new energy efficient production pathways for transportation biofuels. This book offers an insight into three promising and innovative pathways for the biological production of biodiesel, ethanol and methane. These unconventional methods should provide higher product yields, less stringent feedstock specifications, lower chemical additive demand, reduced waste production and much better energy balances when compared to more traditional methods. The first pathway is the enzymatic production of a new kind of biodiesel where no glycerol waste is produced and a twenty percent higher product yield is obtained. The other two pathways are based on the biological conversion of syngas into ethanol or methane using various kinds of lignocellulosic biomass as the starting point. For each of the three pathways a comparison will be made with competing production methods. The contents reflect extended desktop research and show practical experimental results. Government scientists, academics and biofuel producers with an interest in novel transportation fuels will all find this book to be essential reading. 24 cm.
