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

Book Description
How the success and popularity of recycling has diverted attention from the steep environmental costs of manufacturing the goods we consume and discard. Recycling is widely celebrated as an environmental success story. The accomplishments of the recycling movement can be seen in municipal practice, a thriving private recycling industry, and widespread public support and participation. In the United States, more people recycle than vote. But, as Samantha MacBride points out in this book, the goals of recycling—saving the earth (and trees), conserving resources, and greening the economy—are still far from being realized. The vast majority of solid wastes are still burned or buried. MacBride argues that, since the emergence of the recycling movement in 1970, manufacturers of products that end up in waste have successfully prevented the implementation of more onerous, yet far more effective, forms of sustainable waste policy. Recycling as we know it today generates the illusion of progress while allowing industry to maintain the status quo and place responsibility on consumers and local government. MacBride offers a series of case studies in recycling that pose provocative questions about whether the current ways we deal with waste are really the best ways to bring about real sustainability and environmental justice. She does not aim to debunk or discourage recycling but to help us think beyond recycling as it is today.

Book Description
The purpose of this project is to compare emissions of greenhouse gases from material recycling with those from virgin material production, both from a material supply perspective and from a recycling system perspective. The method for estimating emissions and climate benefits is based on a review, followed by a selection, of the most relevant publications on life cycle assessment (LCA) of materials for use in Denmark, Norway and Sweden. The proposed averages show that emissions from material recycling are lower in both perspectives, comparing either material supply or complete recycling systems. The results can be used by companies and industry associations in Denmark, Norway and Sweden to communicate the current climate benefits of material recycling in general. They may also contribute to discussions on a societal level, as long as their average and historic nature is recognised.

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
