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 :

Microbes are the predominant form of life on the planet due to their broad range of adaptation and versatile nutritional behavior. The ability of some microbes to inhabit hostile environment incompatible with most forms of life means that their habitat defines the extent of the biosphere and delineates the barrier between the biosphere and geosphere. The direct and indirect role of microbes that include bacteria, fungi, actinomycetes, viruses, mycoplasma, and protozoans are very much important in development of modern human society for food, drugs, textiles, agriculture, and environment. Furthermore, microorganisms and their enzyme system are responsible for the degradation of various organic matters. Microbes for Sustainable Development and Bioremediation emphasizes the role of microbes for sustainable development of ecosystem. Environmental microbiology role in biogeochemical cycle and bioremediation of environmental waste is major theme, which comprises the following aspects: Bacterial phytoextraction mechanism of heavy metals by native hyperaccumulator plants from complex waste-contaminated site for eco-restoration Role of microbial enzyme for eco-friendly recycling of industrial waste Field-scale remediation of crude oil–contaminated desert soil and treatment technology Microbial technology for metal recovery from e-waste printed circuit board Impact of genomic data on sustainability of ecosystem Methane monooxygenases: their regulations and applications Role of microbes in environmental sustainability and food preservation This book will be directly beneficial to researchers and classroom students, in areas of biotechnology, environmental microbiology, molecular biology, and environmental engineering with specialized collection of cutting-edge knowledge.

Book Description :

The use of water based inks is on the rise. Sub micron pigment particles are used for flexographic and inkjet water based inks. Conventional deinking eliminates larger particles than those from these new ink systems. Therefore, water-based inks represent recycling difficulty. Deinking experiments of water based inks are carried out. The deinking strategy initially investigated elimination of pressure sensitive adhesive due to similar acrylic polymer chemistry used in water based inks. The impact of pH on stickies and ink agglomeration during deinking is studied. Experiments in acidic regions show growth of acrylic inks and stickies agglomerates, simplifying elimination. Pre recycling of water based inks is explored. Exceptional cleanliness of acidic circuit waters compared to alkaline is demonstrated. Conventional wisdom claims an alkaline environment is needed for ink detachment from paper. It is found that the benefit of acidic milieu is the agglomeration of the pigment-resin complex of water based ink. Further, flotation deinking of model inks is performed. Agglomeration and flotation of inkjet inks using surfactants is performed to better understand ink behavior during deinking while limiting its redeposition. Three types of food grade soybean oils are tested for utilization in the paper recycling industry. Fatty acids extracted from oils are utilized in one loop flotation deinking of offset printed paper. Extracted fatty acids A, B and C had varied acid and saponification number. The effect of each of the soy-oil fatty acid on deinking is studied. Deinking results are compared to INGEDE 11p procedure, using oleic acid. It is discovered that fatty acids C and B have better deinking performance than oleic acid. Lower acid number acids perform better. Acid C and bentonite clay is used in one loop flotation deinking of inkjet printed paper. Fatty acid C is compared against oleic acid. It is determined that fatty acid C has positive effects on deinkability. The surface of the bentonite clay is altered by coating it with fatty acid C. Bentonite clay is successful in removing sub-micron hydrophilic inkjet ink pigment particles. Clay has a positive effect on the discoloration of recycled water.

Up to date and wide in scope, this is a chance for non-specialists to acquaint themselves with this rapidly growing field. '...The quality...is so great that there is no hesitation in recommending it as ideal reading for any student requiring an introduction to enzymes. ...Enzymes in Industry - should command a place in any library, industrial or academic, where it will be frequently used.' The Genetic Engineer and Biotechnologist 'Enzymes in Industry' is an excellent introduction into the field of applied enzymology for the reader who is not familiar with the subject. ... offers a broad overview of the use of enzymes in industrial applications. It is up-to-date and remarkable easy to read, despite the fact that almost 50 different authors contributed. The scientist involved in enzyme work should have this book in his or her library. But it will also be of great value to the marketing expert interested in the present use of enzymes and their future in food and nonfood applications.' Angewandte Chemie 'This book should be available to all of those working with, or aspiring to work with, enzymes. In particular academics should use this volume as a source book to ensure that their 'new' projects will not 'reinvent the wheel'.' Journal of Chemical Technology and Biotechnology

Book Description :

Winner of the International Solid Waste Association's 2014 Publication Award, Handbook of Recycling is an authoritative review of the current state-of-the-art of recycling, reuse and reclamation processes commonly implemented today and how they interact with one another. The book addresses several material flows, including iron, steel, aluminum and other metals, pulp and paper, plastics, glass, construction materials, industrial by-products, and more. It also details various recycling technologies as well as recovery and collection techniques. To completely round out the picture of recycling, the book considers policy and economic implications, including the impact of recycling on energy use, sustainable development, and the environment. With contemporary recycling literature scattered across disparate, unconnected articles, this book is a crucial aid to students and researchers in a range of disciplines, from materials and environmental science to public policy studies. Portrays recent and emerging technologies in metal recycling, by-product utilization and management of post-consumer waste Uses life cycle analysis to show how to reclaim valuable resources from mineral and metallurgical wastes Uses examples from current professional and industrial practice, with policy and economic implications
