Environmentally Friendly Production Of Pulp And Paper

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.

Solving the pulp and paper industries' environmental problems is essential to maintaining the forest industry and accommodating the changing economic needs of forest communities. This book explores the construction of new mills--operating on new technology that does not produce pollutants--which are vital to the pulp and paper industry.

This book features in-depth and thorough coverage of Minimum Impact Mill Technologies which can meet the environmental challenges of the pulp and paper industry and also discusses Mills and Fiberlines that encompass “State-of-the-Art” technology and management practices. The minimum impact mill does not mean "zero effluent", nor is it exclusive to one bleaching concept. It is a much bigger concept which means that significant progress must be made in the following areas: Water Management, Internal Chemical Management, Energy Management, Control and Discharge of Non-Process Elements and Removal of Hazardous Pollutants. At the moment, there is no bleached kraft pulp mill operating with zero effluent. With the rise in environmental awareness due to the lobbying by environmental organizations and with increased government regulation there is now a trend towards sustainability in the pulp and paper industry. Sustainable pulp and paper manufacturing requires a holistic view of the manufacturing process. During the last decade, there have been revolutionary technical developments in pulping, bleaching and chemical recovery technology. These developments have made it possible to further reduce loads in effluents and airborne emissions. Thus, there has been a strong progress towards minimum impact mills in the pulp and paper industry. The minimum-impact mill is a holistic manufacturing concept that encompasses environmental management systems, compliance with environmental laws and regulations and manufacturing technologies.

This technical report examines the environmental issues facing the pulp & paper industry & shows how these issues can be addressed. It discusses the production process, the origins of pollution & other impacts on the industry. It also recommends procedures for reducing these impacts.

This book gives emphasis to wood fiber raw materials, alternative sources of fibers for paper production, environmental issues, paper quality improvement and cost of paper production. Varieties of non-wood raw materials, including kenaf, rice straw, empty fruit bunches of palm trees, bamboo, bagasse, etc., are considered in this book. The process of fiber treatment also varied to meet paper quality improvement. Different organosolv processes of fiber treatment are discussed. Considering contemporary issues, one particular chapter analyzes the environmentally friendly way of processing non-wood fibers for paper production. The book also contains a chapter on the by-product raw materials of paper production and their profitable applications.

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.

The problems recyclers face with wastepaper are connected to the issues addressed by forest advocates, as well as to the difficulties confronted by those involved with industrial pollution from the paper industry. In this richly detailed study, Maureen Smith shows how industrial and environmental analysis can be synthesized to clarify these complex problems and produce solutions. Smith outlines the basic structural characteristics of the U.S. pulp and paper industry and its relationship to the larger forest products sector, as well as its patterns of domestic and global fiber resource use. She then reviews the core technologies employed in virgin pulp production, with an emphasis on their environmental impacts, the role of technological innovation, and the relationships between fiber choices and pollution prevention. Building on this base she reveals structural barriers within the industry that have impeded positive change and shows how these barriers are reinforced by the traditional isolation of environmental policy domains.The study includes a comparative analysis of how organochlorine pollution from pulp mills has been addressed in the United States, Europe, and Canada (and why the United States has seen the slowest rate of progress); an assessment of commodity trade patterns in the industry and how they are linked to resource demand; an examination of the momentum building around annual plant fiber use and the diverse interests it reflects; and a review of recent developments in paper recycling within the context of historical trends in fiber utilization. A case study of the controversial environmental review process of the largest recycled pulp and paper mill ever proposed ties together earlier elements of the book and forms the basis for the conclusions. In closing, Smith argues convincingly against narrowly focused attempts to "fix" the problems associated with the industry, and offers practical guidance on new frameworks and approaches for industrial restructuring. She highlights the need for regional perspectives that integrate environmental, social, and economic objectives. Urban and Industrial Environment series

Pulp and paper production has increased globally and will continue to increase in the near future. Approximately 155 millions tons of wood pulp is produced worldwide and about 260 millions is projected for 2010. To cope with the increasing demand, an increase in production and improved environmental performance is needed as the industry is under constant pressure to reduce environmental emissions to air and water. This book gives updated information on environmentally benign approaches for pulp bleaching, which can help solve the problems associated with conventional bleaching technologies. * Main focus is on the environmentally friendly technologies that can help solve some of the problems associated with conventional bleaching technologies * Information given is up-to-date, authoritative and cites the experiences of many mills and pertinent research, which is of interest to those working in the industry or intending to do so * Covers in great depth all the aspects of various bleaching processes including environmental issues
