Available in PDF, EPUB and Kindle. Book excerpt: Five materials were applied to either a kraft pulp furnish or to a kraft paper and were removed by conventional removal processes. Uncontaminated kraft paper subjected to the same removal processes determined that the process, not the contaminant, was responsible for changes in sheet properties. Handsheet tensile properties, an indication of fiber bonding, and zero-span tensile tests, a measure of fiber strength, are reported. Aqueous polyethylene removal and deinking processes restored fiber bonding and strength almost to their initial levels. Wet strength removal, hot melt, and polyethylene solvent extractions resulted in fiber property reductions similar in magnitude to that of the recycled control. Asphalt dispersion caused the largest decrease in fiber properties. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to alkaliphiles, their microbiology, biotechnological applications and adaptive mechanisms. Alkaliphiles are extremophilic organisms that are adapted to thrive in alkaline environments. Over the years, a wide variety of alkaliphiles belonging to domain Bacteria, Archaea and Eukarya have been isolated and studied. These organisms use various adaptive mechanisms to thrive in ‘extreme’ alkaline environments, and some of these adaptive mechanisms are of immense importance to a range of biotechnological applications. In this book, readers will learn about the adaptive strategies of alkaliphiles in colonizing alkaline habitats, with a main focus on: (1) the production of enzymes that are active and stable in the high pH environment, and (2) the production of acids that decrease the pH of their immediate surrounding environment. Enzymes that are operationally stable at high pH (also known as alkaline active enzymes) are desirable in several applications such as detergent formulating and leather tanning processes, and they are among the major selling enzymes and the most important industrial enzymes. The growing demand in many existing and emerging biotechnological applications led to the discovery, characterization, engineering and evaluation of diverse types of alkaline active enzymes. In addition to the use of these fascinating enzymes in biotechnological applications, readers will discover the mechanisms of action and stability of these enzymes at extreme pH. Studies have shown that some alkaliphiles decrease the severity of the high pH of their media by producing substantial amount of organic acids, which could be of great interest in various applications presented in this book. In addition to enzymes and organic acids, other products of biotechnological importance such as carotenoids, bioactive substances, and chelators have also attracted researchers’ attention. Whole-cells of alkaliphiles have been used as food and feed, and are also useful in environmental applications such as in waste treatment and construction.
