The protection of groundwater and surface water from contamination by the escape of contaminant from waste disposal is now an important consideration in many countries of the world.
This book deals with the design of "barrier systems"which separate waste from the surrounding environment and which are intended to prevent contamination of both groundwater and surface waters. The authors discuss all key aspects of the design of barrier systems, including leachate collection, natural barriers such as clayey aquitards, clay liners, geomembrane and composite liners, providing a state-of-the-art work of reference of great value to engineers and environmentalists alike. This retitled second edition of "Clayey Barrier Systems for Waste Disposal" has been fully revised and updated, with new chapters on geomembranes and geosynthetic clay liners as well as a number of new chapters.
Engineers involved with waste management, geotechnics and landfill design will use this book in order to understand the concepts, find out about the latest developments and subsequently apply them to practical applications relevant to the design of barrier systems.

The first edition described the concept of Integrated Waste Management (IWM), and the use of Life Cycle Inventory (LCI) to provide a way to assess the environmental and economic performance of solid waste systems. Actual examples of IWM systems and published accounts of LCI models for solid waste are now appearing in the literature. To draw out the lessons learned from these experiences a significant part of this 2nd edition focuses on case studies - both of IWM systems, and of where LCI has been used to assess such systems. The 2nd edition also includes updated chapters on waste generation, waste collection, central sorting, biological treatment, thermal treatment, landfill and materials recycling.

This 2nd edition also provides a more user-friendly model (IWM-2) for waste managers. To make it more widely accessible, this edition provides the new tool in Windows format, with greatly improved input and output features, and the ability to compare different scenarios. A detailed user's guide is provided, to take the reader through the use of the IWM-2 model, step by step. IWM-2 is designed to be an "entry level" LCI model for solid waste - user-friendly and appropriate to users starting to apply life cycle thinking to waste systems - while more expert users will also find many of the advanced features of the IWM-2 model helpful. IWM-2 is delivered on CD inside the book.

Solid waste management issues are a highly emotive topic. Disposal costs need to be balanced against environmental impact, which often results in heated public debate. Disposal options such as incineration and landfill, whilst unpopular with both the public and environmental pressure groups, do not pose the same environmental and health risks as, for example, recycling plants. This book, written by international experts, discusses the various waste disposal options that are available (landfill, incineration, composting, recycling) and then reviews their impact on the environment, and particularly on human health. Comprehensive and highly topical, Environmental and Health Impact of Solid Waste Management Activities will make a strong contribution to scientific knowledge in the area, and will be of value to scientists and policy-makers in particular.

Interest in solid waste disposal has been growing since the early 1960s, when researchers emphasized the potential for solid waste to harbor pathogenic microorganisms. Since then, society has become more interested in the environmental impacts of solid waste treatment and disposal, and how biological processes are used to minimize these impacts. This new text provides a basic understanding of the unique microbial ecosystems associated with the decomposition of municipal solid waste (MSW). It addresses the challenges of sampling and assaying microbial activities in MSW and describes preferred methods. The decomposition of MSW under anaerobic conditions in landfills and digestors is described, as well as under aerobioconditions during composting. The Microbiology of Solid Wastes discusses the need to consider MSW as an integrated system of collection, recycling, treatment, and disposal. A better understanding of solid waste microbiology will contribute to safe and economical solid waste management. Microbiologists, environmental engineers, and solid waste managers will all find this a useful reference.

This work offers an accessible discussion of current and emerging separation processes used for waste minimization, showing how the processes work on a day-to-day basis and providing troubleshooting tips for equipment that doesn't function according to design specifications. It describes the fundamentals of over 30 processes, types of equipment available, vendors, and common problems encountered in operations with hazardous waste.

This Issue follows on from the review of waste incineration in Issue 2, providing a thorough and detailed review of other waste management options. Waste generation affects everyone, and its treatment and disposal are matters of increasing complexity and urgency. This book examines the environmental impact of sewage and industrial effluent treatment on inland and coastal waters, in the atmosphere and on land. It also looks into current practice in the design, engineering, operation and control of landfill sites, and the effect of changes in regulatory policy. A wide range of waste management practices result in atmospheric discharges and this book reviews the localized impacts and mitigation of the discharge and the regulatory framework within which waste management has to operate. The book also covers the general and technical issues facing the materials recycling industry; looks into the factors affecting deep underground storage of radioactive fuel waste produced by nuclear reactors; and provides data from a number of case studies in cost-benefit analysis, demonstrating the utility of a consistent economic theory of waste management.

FROM THE PREFACE
Sanitary landfills are the most widely utilized method of solid waste disposal around the world. With increased use and public awareness of this method of disposal, there is much concern with respect to the pollution potential of the landfill leachate. Depending on the composition and extent of decomposition of the refuse and hydrological factors, the leachate may become highly contaminated. As leachate migrates away from a landfill, it may cause serious pollution to the groundwater aquifer as well as adjacent surface waters. There is growing concern about surface and groundwater pollution from leachate. Better understanding and prediction of leachate generation, containment, and treatment are needed.
This book contains a literature review of various methodologies that have been developed for prediction, generation, characterization, containment, control, and treatment of leachate from sanitary landfills. The contents of this book are divided into nine chapters. Each chapter contains theory and definition of the important design parameters, literature review, example calculations, and references.
Chapter 1 is devoted to basic facts of solid waste problems current status and future trends towards waste reduction and recycling. Chapter 2 provides a general overview of municipal solid waste generation, collection, transport, resource recovery and reuse, and disposal options. The current status of sanitary landfill design and operation, problems associated with the landfilling, and future trends are presented in Chapter 3. Methods of enhanced stabilization, recycling landfill space, methane recovery, and above grade landfilling, and closure and post closure care of completed landfills are also discussed in detail. Chapter 4 provides a general overview of Subtitle D regulations and its impact upon sanitary landfilling practices. Chapter 5 is devoted entirely to moisture routing and leachate generation mechanisms. Examples of calculation procedure for determining the leachate quantity produced at a landfill are presented. Chapter 6 is devoted to chemical characterization of leachate that changes over the life of the fill. Both theoretical and experimental results are provided to estimate the leachate quality. Chapter 7 provides leachate attenuation processes and mechanisms. Chapter 8 is devoted to leachate collection systems. Natural soil sealants, admixed materials and synthetic membranes, their effectiveness, and methods of installation and economics are fully discussed. Chapter 9 provides a detailed review of leachate treatment methodology. Kinetic coefficients and treatment plant design considerations are summarized for the sole purpose of assisting con- sultants to design leachate treatment facilities. Leachate treatment case histories and numerous process trains are presented for treating leachate from young landfill. The book also describes how the process train can be changed effectively as leachate quality changes with time.

Waste incineration is finding increasing favour as a waste disposal method and this Issue considers the topic of waste disposal and the place of incineration as an option. It reviews the emissions and environmental impacts of incineration and available control technologies, specific research upon emissions of trace metals and organic micropollutants, and the methodologies for environmental impact assessment. There is currently great interest and considerable controversy over waste incineration and this book gives a dispassionate view of the scientific and technical issues involved. It provides a broad overview of the role incineration can play in waste management and looks at how environmental impacts may be managed and assessed. For municipal waste, when coupled with energy recovery, waste incineration provides an efficient, spatially compact means of bulk waste reduction, which is widely favoured over landfill, and for some chemical wastes, provides the only presently viable disposal option. This book places incineration in the context of other waste disposal options and examines the relative benefits and environmental impacts in a balanced way.

Introduces the most up-to-date techniques for soil remediation, including chemical fixation/stabilization, soil vapor extraction, thermally enhanced vapor stripping, biodegradation, and air spargingwritten in a style accessible to nonspecialists.
