Due to the extensive use of treated wood products throughout urban and agricultural communities, information concerning the environmental and health risks associated with treated wood is very much in demand. Responding to increasing need for a comprehensive and cohesive source on this topic, Environmental Impacts of Treated Wood compiles the latest information concerning regulations, environmental impact studies, new wood preservative formulations, and state-of-the-art disposal technologies available for minimizing environmental impacts caused by treated wood.Beginning with a background of the production of the most common treated wood products, this book discusses how chemical leaching and transport of certain wood preservatives affect the environment, particularly chromated copper arsenate. A separate section is devoted to case studies that evaluate possible links with cancer and other health risks with repeated exposure to treated wood. Several chapters discuss ways to measure exposure and review various approaches to risk assessment and management. Because treated wood products last a long time, the book also considers the disposal of treated wood in terms of human and environmental impact. It explores novel disposal technologies and practical strategies for complying with regulatory phase-outs of certain treated wood products within the U.S., Canada, Europe, Australia, and many Asian countries. These include recycling, bioremediation, thermal treatment, and landfills.Environmental Impacts of Treated Wood provides a timely compilation of perspectives necessary for making informed, conscientious decisions in the production, use, and disposal of treated woods that will minimize the environmental impact and human exposure risks associated with treated wood products today.

Solid waste management is a global concern, and landfilling remains the predominant management method in most areas of the world.

Solid waste management is a global concern, and landfilling remains the predominant management method in most areas of the world.

Using biotechnology to help control landfill processes can mitigate costs, shorten the time needed to process solid waste, and ease the typical ecological damage to the land being used. This first-of-its-kind book provides regulators, designers, landfill owners, and operators with information that supports the utility of landfill bioreactors and provides design and operating criteria essential for the successful application of this technology. It pulls together laboratory, pilot, and full-scale experiences into one concise guide to designing and running municipal landfills as bioreactors.Landfill Bioreactor Design and Operation covers the history and background of landfill technology, research studies of actual bioreactor landfills, expected leachate and gas yields, specific design criteria, operation guidelines, and reuse of landfill sites to avoid having to establish new sites. For anyone looking for an alternative to large, wasteful landfill sites, this book provides a practical alternative to the problem.

CDD in the past has not received the same attention as other waste streams (e.g., municipal solid waste), but with the growing recognition of the environmental and economic importance of proper CDD management, this material now is the focus of attention of many government agencies and private businesses.
