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. Desc4ibes the ex shu technique of thermal desorption of soil contaminants-a low-cost aftemative to incineration for the removal of organics.

Hazardous Waste Site Remediation is an outstanding textbook that reviews specific treatment processes, as well as pertinent basic concepts in organic geochemistry, material balance mass transfer, thermodynamics, and kinetics. Following a quantitative approach to source control, the text covers regulations, materials handling, engineering principles, soil vapor extraction, chemical extraction and soil washing, solidification and stabilization, and chemical destruction. It also explores topics in bioremediation, thermal processes, risk assessment, and waste minimization. A solutions manual is available.

Material Recovery Facility Design Manual is a comprehensive guide to the technical and economic aspects of material recovery facility (MRF) equipment and methods for separating and handling separable of source-separated recyclables in a typical municipal solid waste stream. For each individual constituent of the solid waste stream, alternative approaches are identified for separation and recovery. For each piece of equipment, the book covers design, theory of operation, sizing and equipment needs, for example shredders and balers.

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.

Discharge of nutrient rich wastewater causes eutrophication of surface water; therefore wastewater treatment before discharge is required. Wastewater stabilization ponds are low cost technology used by developing countries but not effective in nitrogen removal due to low nitrifier biomass in the water column. Introduction of surface area for attachment of nitrifiers has therefore been proposed. This thesis reports the performance of pilot scale wastewater stabilization ponds fitted with baffles. The effect of baffles on nitrogen removal under tropical and two operational conditions was investigated. Under TKN/BOD ratio of 0.67, the baffled ponds performed better in nitrogen removal than the control pond. Total nitrogen mass balances showed that nitrification-denitrification, algal uptake and sedimentation were principle nitrogen removal mechanisms in biofilm waste stabilization ponds This study shows the potential of biofilms in improving nitrogen removal in wastewater stabilization ponds. The BOD and TSS concentrations were sufficiently low to permit for reuse in irrigation. If the objective is reuse and optimization of resources, the effluents from the ponds had sufficient nitrogen content for use in agriculture.

This volume provides in-depth coverage of environmental pollution sources, waste characteristics, control technologies, management strategies, facility innovations, process alternatives, costs, case histories, effluent standards, and future trends in waste treatment processes. It delineates methodologies, technologies, and the regional and global effects of important pollution control practices. It focuses on specific industrial and manufacturing wastes and their remediation. Topics include: heavy metals, electronics, chemical, and textile manufacturing.

This title includes a number of Open Access chapters. Increasing attention is being paid to the valorization of solid wastes-converting them into energy or other useful products. This book describes recent research into methodologies and technologies for managing various forms of solid waste, while at the same time generating energy and revenue with less impact on the environment. Topics include combustion, gasification, pyrolysis, and hydrothermal carbonization. The transition from a fossil fuel-based economy to a more sustainable economy will require a solid foundation of ongoing scientific research. The editor of this compendium, a well-respected researcher in the field, has selected studies that help to build that foundation.

Developed from the efforts of a multiyear, international project examining how persistent, bioaccumulative, and toxic (PBT) chemicals are evaluated and managed, Persistent, Bioaccumulative, and Toxic (PBT) Chemicals: Technical Aspects, Policies, and Practices focuses on improving the processes that govern PBTs. Incorporating science and policy literature-as well as interviews and panel discussions featuring experts from around the world-this book provides you with an international perspective of PBT policies (centering on Europe, Asia, and North America), and reveals major findings and recommendations for improving PBT science, laws, and policies. It includes case studies of specific chemicals, provides an introduction to the overall subject of toxic chemicals, and weighs in on science and policy expansion for PBTs. It also provides summary tables of important PBTs, and discussions on the number of PBTs in commerce, weight of evidence approaches, market deselection, and international management. The text: Assesses the history, current practice, and future of PBT management Considers the roles scientific data, modeling, and conventions play in identifying and regulating PBTs Explores the number of PBTs in commerce and the growing role of weight of evidence (WOE) in the making of PBT determinations Identifies issues that are likely to come up in WOE judgments Examines international, national, subnational, and regional PBT policies Includes a comprehensive and easy-to-understand analysis of PBT science and policy This book reviews the current science, policies, and practices surrounding the regulation of PBTs.

Sludge Management provides up-to-date information on sludge treatment, reuse and disposal. A comprehensive coverage of all issues related to sludge management is included with local through global coverage of all sludge management practices. Conventional to advanced technologies for sludge management with available case studies from both developing and developed countries are covered in this book. Given the responsibility of engineers to develop the technological tools to meet the increasingly stricter standards for sludge treatment and disposal, the main attraction of the book principally relies on its technical content that reviews all the points to be considered in sludge management from engineering and technological perspectives. Sludge Management can be used for planning, designing, and implementing waste sludge management projects. Moreover, this book can be used as a standard textbook in Universities for Master and Doctoral students. Also, academics, researchers, scientists, and practicing engineers working in the field of sludge management would find the book very informative and a source of interesting case studies.

This book contains detailed and structured approaches to tackling practical decision-making troubles using economic consideration and analytical methods in Municipal solid waste (MSW) management. Among all other types of environmental burdens, MSW management is still a mammoth task, and the worst part is that a suitable technique to curb the situation in developing countries has still not emerged. Municipal Solid Waste Management in Developing Countries will help fill this information gap based on information provided by field professionals. This information will be helpful to improve and manage solid waste systems through the application of modern management techniques. It covers all the fundamental concepts of MSWM; the various component systems, such as collection, transportation, processing, and disposal; and their integration. This book also discusses various component technologies available for the treatment, processing, and disposal of MSW. Written in view of actual scenarios in developing countries, it provides knowledge to develop solutions for prolonged problems in these nations. It is mainly for undergraduate and postgraduate students, research scholars, professionals, and policy makers.

This title includes a number of Open Access chapters.

It covers treatment and pretreatment technologies and methodologies, energy recovery from solid wastes, recycling and reuse, additional cutting-edge valorization methodologies. Primarily aimed at researchers and advanced students in biochemical, engineering, and environmental fields, this book should also provide a valuable reference for municipal legislators and industry practitioners.

Solid waste is a major urban challenge worldwide and decisions over which technologies or methods to apply can have beneficial or detrimental long-term consequences. Inappropriate management of solid waste can lead to damaging environmental impacts, particularly in the megacities of the Global South. Urban Recycling Cooperatives explores the multiple narratives and interdisciplinary nature of waste studies, drawing attention to the pressing social, economic and environmental challenges related to waste management. The book asks questions such as: how do we define waste and our relation to it; who is involved in dealing with waste; and what power interactions become manifest over issues of accessing and managing waste? In recent years informal cooperatives have emerged, devoted to recycling household and business waste before reclassifying it and redirecting it to the authorities. Hence, these workers are able to reclaim significant amounts of natural resources and thus contribute to the saving of resources and lessened waste management expenditures. With particular reference to the Brazilian megalopolis of Sao Paulo, this book describes this paradigm shift in the general understanding of waste as unwanted discard towards the recognition of waste as a resource that must be recovered for reuse or recycling. It would be of interest to students and policy makers working in international development and waste management.

Sanitation and intestinal health is something we often take for granted today. However, people living in many regions of the developing world still suffer with debilitating diseases due to the lack of sanitation. Despite its clear impact upon health in modern times, sanitation in past populations is a topic that has received surprisingly little attention. This book brings together key experts from around the world to explore fascinating aspects of life in the past relevant to sanitation, and how that affected our ancestors. By its end readers will realize that toilets were in use in ancient Mesopotamia even before the invention of writing, and that flushing toilets with anatomic seats were a technology of ancient Greece at the time of the minotaur myth. They will see how sanitation compared in ancient Rome and medieval London, and will take a virtual walk around the sanitation of York at the time of the Vikings. Readers will also understand which intestinal parasites infected humans in different regions of the world over different time periods, what these parasites tell us about early human evolution, later population migrations, past diet, lifestyle, and the effects of sanitation technology. There is good evidence that over the millennia people in the past realized that sanitation mattered. They invented toilets, cleaner water supplies, drains, waste disposal and sanitation legislation. While past views on sanitation were very different to those of today, it is clear than many past societies took sanitation much more seriously than was previously thought.

One of the physical costs of our society's breakneck consumption, sprawl, and technological innovation and production is the increasing amount of terrain relegated to accommodating the resulting waste and wasted space. These "marginal landscapes" can be divided into four distinct categories: sinks; ruins or abandoned land; toxic or damaged land; and waste landscapes. Although Professor Engler discusses all four types, she is concerned mostly with waste landscapes - "landfills, recycling and waste transfer centers, and sewage treatment plants," as she addresses two distinct aspects of waste landscapes: 1) the historic and cultural context of waste, and 2) the professional planning practices and aesthetic concerns of those who deal with waste and its landscapes. Ultimately, Professor Engler seeks to change our ideas about waste places through her discussion of how landscape design can function within the scientific and technological parameters of safety and environmental concerns to make waste places more central to our thinking and perception. In so doing, she reviews the physical evolution of waste sites, and scrutinizes perceptions and representations of these landscapes, and grounds her ideas in critiques of what environmental designers and artists have done recently with waste places to change public perceptions. Designing America's Waste Landscapes is a pioneering and original work that will appeal to professional planners and landscape designers, and students and scholars in landscape design and planning, environmental studies, urban studies, cultural geography, and even the history of technology.
