Landfill Waste Pollution And Control

This book addresses a pollution hazard prevalent in most cities and large towns world-wide by providing an understanding of the scientific and technical control of the landfill method of domestic and non-domestic waste disposal, considered within the framework of integrated waste management. Landfill disposal is practised world-wide, and is cheap and convenient but, if poorly managed, poses a serious threat to the environment. This pollution threat is a source of concern to regulating authorities and environmental pressure groups. This comprehensive text reflects the authority of the author’s considerable experience in assessment and remediation of landfill sites, which he has taught in post-graduate courses on hazardous waste management, and in running international programmes on waste and contaminated land-related subjects for industry. Dr. Westlake’s expertise also reflects his work in association with the Environmental Safety Centre at the Harwell Laboratory. Featuring the microbial degradation of waste within landfills, with an understanding of hazards associated with the production, migration and control of landfill gas and leachate, the book also points to the benefits to be obtained from gas production. There is important discussion on the monitoring of potentially dangerous dormant sites, and much helpful advice on trouble shooting. The text is set in the context of regulatory controls and assesses their impact, while at the same time looking at the way forward for waste disposal by landfill. There is coverage of legislative requirements and constraints including those from the European Union reflecting official attitudes. There is growing international consensus that EU regulations can be interpreted and applied as a benchmark in relation to legal practices and attitudes in all countries throughout the world Addresses a pollution hazard prevalent in most cities and large towns world-wide Provides an understanding of the scientific and technical control of the landfill method of domestic and non-domestic waste disposal, considered within the framework of integrated waste management Provides an important discussion on the monitoring of potentially dangerous dormant sites

Pollution Control Technology for Leachate from Municipal Solid Waste explores the physical, chemical and biological factors that produce leachate and technological solutions for its control. The book introduces the integrated and pre-treatment leachate treatment processes that are necessary to deal with the variations of pollutants in leachate. Real world case-studies are provided to illustrate these treatment processes, along with leachate treatment engineering process design and the construction of municipal solid waste incinerator power plants. This book will be of particular interest to Civil, Chemical and Environmental Engineers, but will also be ideal for Environmental Scientists. Provides quantity and quality prediction models, along with properties of effluent concentrated leachate liquid Includes physical and chemical treatment processes for leachate, including ammonia nitrogen removal using struvite precipitation, crystal variation and microstructure of the struvite, etc. Covers leachate treatment engineering processes for design and construction of treatment plants

Pollution Control and Resource Recovery: Municipal Solid Wastes at Landfill provides pollution control and resource reuse technologies that cover the research and development achievements gained in recent years, providing the most up-to-date information on an emerging field in solid waste management. Provides technology and methods for the recycling of aged refuse from closed landfills Includes leachate generation processes in municipal solid waste landfills Presents novel approaches to landfilling for leachate and methane control, covering the research and development achievements gained in recent years

Municipal solid waste (MSW) disposal is an ever-increasing problem in many parts of the world, especially in developing countries. To date, landfilling is still the preferred option for the disposal and management of MSW due to its low-cost operation. While this solution is advantageous from a cost perspective, it introduces a high level of potential pollutants which can be detrimental to the local environment. Control and Treatment of Landfill Leachate for Sanitary Waste Disposal presents research-based insights and solutions for the proper management and treatment of landfill leachate. Highlighting relevant topics on emerging technologies and treatment innovations for minimizing the environmental hazards of waste disposal, this innovative publication contributes to filling in many of the gaps that exist in the current literature available on leachate treatment. Waste authorities, solid waste management companies, landfill operators, legislators, environmentalists, graduate students, and researchers will find this publication beneficial to their professional and academic interests in the area of waste treatment and management.

The Handbook of Environment and Waste Management, Volume 2, Land and Groundwater Pollution Control, is a comprehensive compilation of topics that are at the forefront of many of the technical advances and practices in solid waste management and groundwater pollution control. These include biosolids management, landfill for solid waste disposal, landfill liners, beneficial reuse of waste products, municipal solid waste recovery and recycling and groundwater remediation.Internationally recognized authorities in the field of environment and waste management contribute chapters in their areas of expertise. This handbook is an essential source of reference for professionals and researchers in the areas of solid waste management and groundwater pollution control, and as a text for advanced undergraduate and graduate courses in these fields.

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
