Green Technologies for Sustainable Production, Volume 1 by Alok Kumar Patel,Amit Kumar Sharma Pdf
RENEWABLE ENERGY INNOVATIONS This critical text, designed for microbiologists, biotechnologists, entrepreneurs, process engineers, chemical engineers, electrical engineers, physicists, and environmentalists, assesses the current knowledge about lab-scale and large-scale production of renewable and sustainable fuels, chemicals, and materials. Global warming is having a huge impact on the world’s ecosystem. Glaciers have shrunk, ice on rivers and lakes is breaking up early, and plant and animal ranges have relocated. On a worldwide scale, the threat posed by climate change and pollution is obvious. A green and sustainable future necessitates using renewable resources to produce fuels, chemicals, and materials. This book investigates diverse bioprocesses that are crucial to everyday life, including the key concerns regarding the generation of biofuels, energy, and food securities, along with waste management. Commercial interest in biotechnological processes has risen to produce pharmaceuticals, health supplements, foodstuffs, biofuels, and chemicals using a biocatalyst such as enzymes, microorganisms, plant cells, or animal cells in a bioreactor. The sustainability of renewable biomass, replacement of depleted fossil fuels, and the mitigation of greenhouse gas emissions from the existing chemical and oil industries are the key benefits of switching to bioproducts. This book discusses bioprocessing to produce biofuels, biobased chemicals, bioproducts, and biomass biorefinery processes. This involves designing novel pretreatment and fractionation technologies for lignocellulose biomass into cellulose, hemicellulose, and lignin and the conversion of these streams into biofuels and biobased chemicals via biochemical and thermochemical routes. This book also covers the advancement of oleaginous microorganisms for biofuels and nutraceutical, biological wastewater treatment. Written and edited by authors from leading biotechnology research groups from across the world, this exciting new volume covers all of these technologies, including the basic concepts and the problems and solutions involved with the practical applications in the real world. Whether for the veteran engineer or scientist, student, manager, or another technician working in the field, this volume is essential for any library.
Adhesive bonding plays an increasing role in the forest product industry and is a key factor for efficiently utilizing timber and other lignocellulosic resources. As synthetic wood adhesives are mostly derived from depleting petrochemical resources and have caused increasing environmental concern, natural product and byproduct-derived adhesives have attracted much attention in the last decades. Although adhesives made from plant and animal sources have been in existence since ancient times, increased knowledge of their chemistry and improved technical formulation of their preparation are still needed to promote their broader industrial applications. The primary goals of this book are to (1) synthesize the fundamental knowledge and latest research on bio-based adhesives from a remarkable range of natural products and byproducts, (2) identify need areas and provide directions of future bio-based adhesive research, and (3) help integrating research findings in practical adhesive application for maximal benefits. This book covers information on a variety of natural products and byproducts and the latest research on formulation, testing and improvement of the relevant adhesives in fifteen chapters written by an international group of accomplished contributors. This book will serve as a valuable reference source for university faculty, graduate students, research scientists, agricultural and wood engineers, international organization advocators and government agency regulators who work and deal with enhanced utilization of agricultural and forest products and byproducts.

Adhesives in general and structural adhesives in particular are the subjects of much academic interest as well as commercial importance. Structural bonding, as a method of joining, offers a number of advantages over mechanical fastening. However, in order to achieve satisfactory results, the proper adhesive must be selected and the appropriate bonding procedures followed. The purpose of Structural Adhesives: Chemistry and Technology is to review the major classes of structural adhesives and the principles of adhesion and bonding as these relate to structural joints. Each chapter provides an overview of the topic under discussion with a list of references to the relevant literature. In addition to describing the chemistry involved, other aspects of structural adhesive technology are covered, such as formula tion, testing, and end uses. Some structural adhesives, especially epoxies and phenolics, have a long history of successful use and are now widely employed. Others, such as the structural acrylics and cyanoacrylates, are beginning to gain industrial acceptance. Urethanes and anaerobics have limited but important uses, while high-temperature adhesives are still largely in the research and development stage.
