Book Description
Pulp and Paper Industry: Chemical Recovery examines the scientific and technical advances that have been made in chemical recovery, including the very latest developments. It looks at general aspects of the chemical recovery process and its significance, black liquor evaporation, black liquor combustion, white liquor preparation, and lime reburning. The book also describes the technologies for chemical recovery of nonwood black liquor, as well as direct alkali regeneration systems in small pulp mills. In addition, it includes a discussion of alternative chemical recovery processes, i.e. alternative causticization and gasification processes, and the progress being made in the recovery of filler, coating color, and pigments. Furthermore, it discusses the utilization of new value streams (fuels and chemicals) from residuals and spent pulping liquor, including related environmental challenges. - Offers thorough and in-depth coverage of scientific and technical advances in chemical recovery in pulp making - Discusses alternative chemical recovery processes, i.e., alternative causticization and gasification processes - Covers the progress being made in the recovery of filler, coating color, and pigments - Examines utilization of new value streams (fuels and chemicals) from residuals and spent pulping liquor - Discusses environmental challenges (air emissions, mill closure) - Presents ways in which the economics, energy efficiency, and environmental protection associated with the recovery process can be improved

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
