Book Description

Industrial Environmental Performance Metrics is a corporate-focused analysis that brings clarity and practicality to the complex issues of environmental metrics in industry. The book examines the metrics implications to businesses as their responsibilities expand beyond the factory gateâ€"upstream to suppliers and downstream to products and services. It examines implications that arise from greater demand for comparability of metrics among businesses by the investment community and environmental interest groups. The controversy over what sustainable development means for businesses is also addressed. Industrial Environmental Performance Metrics identifies the most useful metrics based on case studies from four industriesâ€"automotive, chemical, electronics, and pulp and paperâ€"and includes specific corporate examples. It contains goals and recommendations for public and private sector players interested in encouraging the broader use of metrics to improve industrial environmental performance and those interested in addressing the tough issues of prioritization, weighting of metrics for meaningful comparability, and the longer term metrics needs presented by sustainable development.




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

Pulp and Paper Industry


Book Description

Pulp and Paper Industry: Emerging Waste Water Treatment Technologies is the first book which comprehensively reviews this topic. Over the past decade, pulp and paper companies have continued to focus on minimizing fresh water use and effluent discharges as part of their move towards sustainable operating practices. Three stages—basic conservation, water reuse and water recycling—provide a systematic approach to water resource management. Implementing these stages requires increased financial investment and better utilization of water resources. The ultimate goal for pulp and paper companies is to have effluent-free factories with no negative environmental impact. The traditional water treatment technologies that are used in paper mills are not able to remove recalcitrant contaminants. Therefore, advanced water treatment technologies are being included in industrial wastewater treatment chains aiming to either improve water biodegradability or its final quality. This book discusses various measures being adopted by the pulp and paper industry to reduce water consumption and treatment techniques to treat wastewater to recover it for reuse. The book also examines the emerging technologies for treatment of effluents and presents examples of full-scale installations. - Provides thorough and in-depth coverage of advanced treatment technologies which will benefit the industry personnel, pulp manufacturers, researchers and advanced students - Presents new treatment strategies to improve water reuse and fulfill the legislation in force regarding wastewater discharge - Presents viable solutions for pulp and paper manufacturers in terms of wastewater treatment - Presents examples of full-scale installations to help motivate mill personnel to incorporate new technologies
