Technology of Paper Recycling


Book Description

This book covers the technology of the recovery of secondary fibre for its use in paper and board manufacture. The editor, who has had substantial practical experience of designing and commissioning paper recycling plants all over the world, leads a team of experts who discuss subjects including sourcing, characterisation, mechanical handling and preparation and de-inking.




Recycling and Deinking of Recovered Paper


Book Description

Recycling and Deinking of Recovered Paper, Second Edition covers recent advances in recycling technologies. This second edition examines this new process, which is more eco-friendly than the virgin-papermaking process, and which uses less energy and natural resources, produces less solid waste and fewer atmospheric emissions, and helps to preserve natural resources and landfill space. In addition, the most recent information about the recycling of fibers into various grades of paper and board, the control of stickies, and the effects of recycled fiber on paper machines are also covered. Recycling technologies have been improved in recent years due to advances in pulping, flotation deinking, and cleaning/screening, resulting in the quality of paper made from secondary fibers remarkably approaching that of virgin paper. Covers all aspects of recycling technologies in great depth Offers up-to-date authoritative information and cites many mills experiences and pertinent research Examines the use of biotech methods for deinking, refining, improving drainage, and stickies control Includes new case studies on paper recycling

The U. S. Paper Industry and Sustainable Production


Book Description

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







Recycled Papers


Book Description

Paper is the largest single component of municipal solid waste, and the recycling of paper must be part of any resolution to the current garbage crisis. Because there are no uniform standards for the generic term "recycled," it is still difficult for paper users to make environmentally responsible purchasing decisions. Myths, misinformation, and confusion abound. This first comprehensive guide to recycled printing and writing papers will therefore be an invaluable resource for anyone involved with printing, production, design, or issues of recycling in general. The book itself, printed on four different types of recycled paper, is a demonstration of the quality that informed designers and publishers can achieve. In concise, nontechnical language, Claudia Thompson explains the dimensions of the solid waste problem, the history of papermaking, the elements of recycled paper production (including current definitions and standards), the physical properties and printing characteristics of recycled papers, the potential impact of designers on recycling, and possibilities for the future. Recycled Papers: The Essential Guide was sponsored by the American Institute of Graphic Arts under the direction of Claudia Thompson, a graphic designer and Principal of Claudia Thompson Design in Cambridge, Massachusetts. Ms. Thompson's work on environmental issues started with the first Earth Day in 1970, and she has been researching the subject of recycled papers since 1988.
