Book Description
Carboxymethylcellulose (CMC), also known as cellulose gum, is manufactured by the chemical synthesis of naturally-derived cellulose with chloroacetic acid. The multifunctional aspects of this product make it favorable for use as a key intermediate or ingredient in several applications. Furthermore, CMC is incorporated as a binding, thickening, stabilizing, emulsifying, suspending, sizing and coating agent in various applications. Cellulose gum enhances the aesthetics of the finished product by imparting a smooth texture and modifies the viscosity of various foods and beverages, superabsorbent hydrogels (as in many personal care products), cosmetics and pharmaceuticals. Textiles, paper and board, oil and gas drilling, paints and adhesives, and soaps and detergents are other major applications in the global market. The present book thus covers a wide range of applications; hence, a great number of people, both academics and industrialists, may find topics of interest about CMC, as well as other cellulosics.Although there are many research publications, patents and reports on CMC, no books about it are yet available. The present book reviews some vital issues and topics on the latest scientific and technological advances in carboxymethylcellulose. This book will provide an essential source of information to readers, in the exploration of possible applications of CMC, and in the generation of new ideas for product development.The book is divided into two volumes: Carboxymethyl Cellulose: Volume I Synthesis and Characterization, and Carboxymethyl Cellulose: Volume II Pharmaceutical and Industrial Applications. The book contains a total of 32 entries on selected topics. Each chapter describes some specific issues and gives the current status of research and technology in the study of synthesis routes or design concepts, methods and fabrication strategies, characterization and applications of CMC products, as well as future prospects for research in the subject area.Highlights of this book include synthesis and formation mechanisms of CMC, structure property relationships, homogeneous and heterogeneous phase modification to create common and functional products, analysis and characterization, absorption and swelling mechanisms, stimuli-responsive and super-absorbency nature, and a wide range of multi-dimensional applications, including human consumption and uses.

Book Description
Paper recycling in an increasingly environmentally conscious world is gaining importance. Increased recycling activities are being driven by robust overseas markets as well as domestic demand. Recycled fibers play a very important role today in the global paper industry as a substitute for virgin pulps. Paper recovery rates continue to increase year after year Recycling technologies have been improved in recent years by advances in pulping, flotation deinking and cleaning/screening, resulting in the quality of paper made from secondary fibres approaching that of virgin paper. The process is a lot more eco-friendly than the virgin-papermaking process, using less energy and natural resources, produce less solid waste and fewer atmospheric emissions, and helps to preserve natural resources and landfill space. Currently more than half of the paper is produced from recovered papers. Most of them are used to produce brown grades paper and board but for the last two decades, there is a substantial increase in the use of recovered papers to produce, through deinking, white grades such as newsprint, tissue, market pulp. By using recycled paper, companies can take a significant step toward reducing their overall environmental impacts. This study deals with the scientific and technical advances in recycling and deinking including new developments. Covers in great depth all the aspects of recycling technologies Covers the latest science and technology in recycling Provides up-to-date, authoritative information and cites many mills experiences and pertinent research Includes the use of biotech methods for deinking, refining. and improving drainage

Book Description
The practice of biotechnology, though different in style, scale and substance in globalizing science for development involves all countries. Investment in biotechnology in the industrialised, the developing, and the least developed countries, is now amongst the widely accepted avenues being used for economie development. The simple utilization of kefir technology, the detoxification of injurious chemical pesticides e.g. parathion, the genetic tailoring of new crops, and the production of a first of a kind of biopharmaceuticals illustrate the global scope and content of biotechnology research endeavour and effort. In the developing and least developed nations, and in which the 9 most populous countries· are encountered, problems concerning management of the environment, food security, conservation of human health resources and capacity building are important factors that influence the path to sustainable development. Long-term use of biotechnology in the agricultural, food, energy and health sectors is expected to yield a windfall of economic, environmental and social benefits. Already the prototypes of new medicines and of prescription fruit vaccines are available. Gene based agriculture and medieine is increasingly being adopted and accepted. Emerging trends and practices are reflected in the designing of more efficient bioprocesses, and in new research in enzyme and fermentation technology, in the bioconversion of agro industrial residues into bio-utility products, in animal healthcare, and in the bioremediation and medical biotechnologies. Indeed, with each new day, new horizons in biotechnology beckon.
