Sanitary Landfill Design And Operation

Solid waste management is a global concern, and landfilling remains the predominant management method in most areas of the world. This book provides a comprehensive view of state-of-the-art methods to manage landfills more sustainably, drawing upon more than two decades of research, design, and operational experiences at operating sites across the world. Sustainable landfills implement one or multiple technologies to control and enhance the degradation of waste materials to realize a multitude of potential benefits during or shortly after the landfill’s operating phase. This book presents detailed approaches in the development, design, operation, and monitoring of sustainable landfills. Case studies showcasing the benefits and challenges of sustainable landfill technologies are also provided to give the reader additional context. The intent of the book is to serve as a reference guide for regulatory personnel, a practical tool for designers and engineers to build on for site-specific applications of sustainable landfill technologies, and a comprehensive resource for researchers who are continuing to explore new and better ways to more sustainably manage waste materials.

Solid waste disposal has become the focus of public awareness and concern for pollution. This book provides a synthesis of existing knowledge on solid waste landfilling, focusing on solving problems with landfill gas, managing laechate and implementing environmentally secure operating procedures.

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 pr

The management of municipal solid waste in many countries throughout the world has changed significantly over the past fifty years, with a shift from uncontrolled dumping or burning to complex systems that integrate multiple processes to recover materials or energy and provide containment to reduce environmental impacts. This volume, the first in the series Waste Management Principles, gives readers a comprehensive overview of advances in sustainable landfill design and operation. The authors developed this volume to serve as a tool for designers, regulators, and other parties interested in sustainable landfill practices and to be used in conjunction with fundamental design methodologies, location-specific regulations, new and emerging research results, and good engineering judgment. Dozens of graphs, figures, and tables provided throughout the text provide the designer with an excellent foundation to begin their analysis and apply the principles from this book to their site or facility. In like fashion, operational experiences are provided throughout, tying in the important underlying fundamental concepts (e.g., accelerated gas production after liquids addition) to critical operational considerations (e.g., how to effectively collect the additional gas that is produced). The body of work presented here results from the development of bioreactor landfill design guidelines for the US Environmental Protection Agency's National Risk Manageme nt Laboratory, along with the combined knowledge and experience of the authors pertaining to sustainable practices for design and operation of sanitary landfills. .
