Sanitary Landfilling: Process, Technology, and Environmental Impact is a collection of essays that discusses the role of landfilling in solid waste management. The book presents the approach in the principles of landfilling and the basic biochemical processes in landfills. The text describes the landfill hydrology and leachate production. It discusses the design and construction of liner systems and the surface capping with natural liner materials. The section that follows describes the soil and refuse stability in sanitary landfills. The book will provide valuable insights for engineers, environmentalists, students, and researchers in the field of solid waste management.

Landfilling of waste has increased dramatically over recent years and there have been many examples of landfills which are unacceptable on environmental and health grounds. This is one of a group of international reference books which address this problem, specifically in this case covering the strongly contaminated wastewater developed from landfills.

Many of the challenges of medical ethics today were nonexistent during the time when Hippocrates wrote his famous oath. In an increasingly complex world, many more new ethical issues will impact on the practice of medicine in the 21st century: quality care, growing patient demand, high technology, the definition of death, and controversies relating to the right to live and the right to die. In addition, there will be questions raised with regard to issues and practices such as research on embryos, genetic engineering, experiments on animals and clinical trials, and the problems of limited medical resources. These can lead to grave dilemmas, causing uncertainty and confusion in the medical profession.This book is based on the lectures and essays on medical ethics by a number of leading Singapore doctors. It records the thoughts of the leaders on medical ethics, and discusses a range of important and controversial issues. It will be a valuable reference for medical students as well as interesting and informative reading for both the professional and the lay reader.

Uses a systematic approach integrating the environmental protection, technical, economic and social issues underlying the siting process and examines their influence upon information requirements as well as the choice of appropriate methodologies of assessment. The first section places the environmental assessment process within the context of relevant regulations and the waste management system. Section two considers the need for facilities and alternative disposal and treatment options. Section three concentrates on the environmental impact study and details important issues in waste facility siting. Lastly, it highlights some key management issues.

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.

In a world where waste incinerators are not an option and landfills are at over capacity, cities are hard pressed to find a solution to the problem of what to do with their solid waste. Handbook of Solid Waste Management, 2/e offers a solution. This handbook offers an integrated approach to the planning, design, and management of economical and environmentally responsible solid waste disposal system. Let twenty industry and government experts provide you with the tools to design a solid waste management system capable of disposing of waste in a cost-efficient and environmentally responsible manner. Focusing on the six primary functions of an integrated system--source reduction, toxicity reduction, recycling and reuse, composting, waste- to-energy combustion, and landfilling--they explore each technology and examine its problems, costs, and legal and social ramifications.
