This collection of comprehensive reviews describes the present knowledge of the enzyme mechanisms involved in the biodegradation of wood and wood components, cellulose, hemicelluloses and lignin by both fungi and bacteria. The extensive knowledge, presented in this volume, was developed in laboratories world-wide over the last few decades and constitutes the foundation for present and future biotechnology in the pulp and paper industry.
Pulp and paper production has increased globally and will continue to increase in the near future. Approximately 155 million tons of wood pulp is produced worldwide and about 260 million is projected for the year 2010. To be able to cope with increasing demand, an increase in productivity and improved environmental performance is needed as the industry is also under constant pressure to reduce and modify environmental emissions to air and water. The authors give updated information on various biotechnological processes useful in the pulp and paper industry which could help in reducing the environmental pollution problem, in addition to other benefits. Various chapters deal with the latest developments in such areas as raw material preparation, pulping, bleaching, water management, waste treatment and utilization. The book also covers the environmental regulations in various parts of the world as well as the role of biotechnology in reducing environmental problems.
This book provides recent developments and future perspectives of pulp and paper processing based on biotechnology to replace conventional environmental unfriendly chemical processes. The use of microorganism and microbial enzymes in various processes such as bleaching, deinking, refining, dissolving pulp, debarking & pitch removal, slime control, wastewater treatment and waste material valorisation are discussed.
Biotechnology in Pulp and Paper Manufacture: Applications and Fundamental Investigations documents the proceedings of the Fourth International Conference on Biotechnology in the Pulp and Paper Industry held in Raleigh, NC and Myrtle Beach, SC, on 16-19 May 1989. This volume contains 68 selected papers organized into seven parts. Part I deals with cell wall degradation and biopulping. It includes papers such as energy savings in biomechanical pumping, and biological degradation and delignification of rice straw. Part II on the enzyme and fungal treatment of pulps presents studies on the improvement of pulp properties by treatment with enzymes or with whole cells. Part III reports on research on new biological treatments for wastewaters produced by the created by the pulp and paper industry. Part IV discusses the conversion of pulping and papermaking byproducts to more valuable products via fermentation. Parts V and VI are devoted to fundamental studies on lignin biodegradation, and on cellulose and hemicellulose biodegradation, respectively. Part VII focuses on molecular genetics research on lignocelluloses-degrading microorganisms.
Selections from the Fourth International Symposium on Biotechnology in the Pulp and Paper Industry comprise this work consisting of 68 co-ordinated chapters by experts from 25 countries.
This book covers both basic and applied sciences in a rather specified area of pulp and paper manufacture. The basic science of lignocellulose enzymology and plant genetics is covered also in many other contexts, whereas the application of biotechnology in process and product development is thoroughly reviewed. All the latest advances as well as new ideas of the research field are covered. This book will serve as an updated and compact information package of biotechnical aspects and the most recent advances of the pulp and paper industry sector.
Implementing Cleaner Production in the pulp and paper industry The large—and still growing—pulp and paper industry is a capital- and resource-intensive industry that contributes to many environmental problems, including global warming, human toxicity, ecotoxicity, photochemical oxidation, acidification, nutrification, and solid wastes. This important reference for professionals in the pulp and paper industry details how to improve manufacturing processes that not only cut down on the emission of pollutants but also increase productivity and decrease costs. Environmentally Friendly Production of Pulp and Paper guides professionals in the pulp and paper industry to implement the internationally recognized process of Cleaner Production (CP). It provides updated information on CP measures in: Raw material storage and preparation Pulping processes (Kraft, Sulphite, and Mechanical) Bleaching, recovery, and papermaking Emission treatment and recycled fiber processing In addition, the book includes a discussion on recent cleaner technologies and their implementation status and benefits in the pulp and paper industry. Covering every aspect of pulping and papermaking essential to the subject of reducing pollution, this is a must-have for paper and bioprocess engineers, environmental engineers, and corporations in the forest products industry.
Pulp and paper mill industries are always associated with the disposal problem of highly contaminated sludge or bio-solids. The development of innovative systems to maximize recovery of useful materials and/or energy in a sustainable way has become necessary. The management of wastes, in particular of industrial waste, in an economically and environmentally acceptable manner is one of the most critical issues facing modern industry, mainly due to the increased difficulties in properly locating disposal works and complying with even more stringent environmental quality requirements imposed by legislation. This book presents a general Introduction on waste management in the pulp and paper industry and contains topics on the generation of waste in pulp and paper mills, waste composition, methods of sludge pre-treatment, processes and technologies for conversion of pulp and paper mill waste into valuable products, waste reduction techniques employed in the pulp and paper Industry worldwide and future trends.
This book presents a state-of-the-art report on the treatment of pulp and paper industry effluents using anaerobic technology. It covers a comprehensive range of topics, including the basic reasons for anaerobic treatment, comparison between anaerobic and aerobic treatment, effluent types suitable for anaerobic treatment, design considerations for anaerobic treatment, anaerobic reactor configurations applied for treatment of pulp and paper industry effluents, present status of anaerobic treatment in pulp and paper industry, economic aspects, examples of full scale installations and future trends.
