Book Description
As populations continue to increase, society produces more and more waste. Yet it is becoming increasingly difficult to build new landfills, and the existing landfills are causing significant environmental damage. Finding solutions is not simple; the problem is enormous in size, vital in terms of its impact on the environment, and complex in scope. This book provides a vast look at solid waste management in North America and seeks solutions to the waste crisis. It describes the magnitude and complexity of the problem, focusing on municipal wastes and placing them in the perspective of other wastes such as hazardous, biochemical, and radioactive debris. It describes the components of an integrated waste management program, including recycling, composting, landfills, and waste incinerators, and it presents in detail the scientific and engineering principles underlying these technologies. To illustrate both the problems and solutions of waste management programs, the authors provide seven case histories, among them the Fresh Kills (Staten Island, New York), the East Carbon Landfill (Utah), and the Lancaster County Municipal Waste Incinerator (Pennsylvania). The Waste Crisis is unique in its attempt to analyze waste management in a broader societal context and to propose solutions based on basic principles. And by doing so, it encourages readers to challenge commonly held perceptions and to seek new and better ways of dealing with waste. As such, this book deserves a place on the bookshelf of anyone who deals with or feels the need to confront the growing problems of waste management.

Book Description
This technical guide seeks to demonstrate that, by encouraging small, continuous improvements in landfill siting, construction, and operation, the accumulative effect over time is the achievement of better operations. The guide does not seek an immediate adoption of sanitary landfill practices. Instead, sanitary landfill is regarded as an eventual goal for which middle- and lower-income countries can plan during the course of several years. A common theme throughout the guide is the emphasis on the practical ways landfills can evolve, as resources and confidence increase, from open dumps to "controlled" dumps to "engineered" landfills and perhaps, one day, to sanitary landfills.

Book Description
Solid Waste Landfilling: Concepts, Processes, Technology provides information on technologies that promote stabilization and minimize environmental impacts in landfills. As the main challenges in waste management are the reduction and proper treatment of waste and the appropriate use of waste streams, the book satisfies the needs of a modern landfill, covering waste pre-treatment, in situ treatment, long-term behavior, closure, aftercare, environmental impact and sustainability. It is written for practitioners who need specific information on landfill construction and operation, but is also ideal for those concerned about the possible return of these sites to landscapes and their subsequent uses for future generations. Includes input by international contributors from a vast number of disciplines Provides worldwide approaches and technologies Showcases the interdisciplinary nature of the topic Focuses on sustainability, covering the lifecycle of landfills under the concept of minimizing environmental impact Presents knowledge of the legal framework and economic aspects of landfilling

Book Description
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.

Book Description
Seven pilot-scale partitioning gas tracer tests (PGTTs) were conducted to assess its accuracy and reproducibility for measuring water in municipal solid waste landfills. Tests were conducted in the same location over a 12-month period, and measured moisture conditions ranged from possible dry waste to refuse with a moisture content of 24.7%. The final moisture content of 24.7% was in reasonable agreement with gravimetric measurements of excavated refuse, where the moisture content was 26.5 " 6.0CI %. Laboratory tests were used to assess the utility of the PGTT for measuring water in small pores, water sorbed to solid surfaces, and the influence of dry waste on PGTTs. These experiments indicated that when refuse surfaces are not completely solvated with water, PGTTs may produce misleading results (negative estimates) of water saturation and moisture content. Two field-scale PGTTs were performed to evaluate the utility of the PGTT method for measuring water saturation and moisture content in a full-scale bioreactor landfill, where waste biodegradation resulted in elevated temperatures and significant landfill gas production. The average water saturation and moisture content were measured for waste volumes of approximately 20 m 3 and results compared to gravimetric measurement of moisture content made on samples collected from the landfill. In the center of the landfill, the moisture content estimated from the PGTT was (M c = 0.26 " 0.03, which was nearly identical to the gravimetric measurement of waste samples taken from the same region (M c = 0.28). PGTT estimated moisture contents in a dry area of the landfill were much smaller (M c = 0.10 " 0.01) and consistent with available gravimetric measurements. Biodegradation of tracers and temporal variations in landfill gas production were minimal and did not influence the tests. These field experiments demonstrate the utility of the PGTT method for measuring water saturation and estimating moisture content in bioreactor landfills with active waste degradation and generation of landfill gases. However, use of the PGTT to estimate the in situ moisture content requires estimates of the refuse porosity, dry bulk density, and temperature, which might limit its application. Laboratory experimental procedures were developed to obtain constitutive relations for fluid flow in refuse. Five different types of experiments were conducted for the same column without any disturbance to model waste samples: a drainage experiment, a multi step outflow experiment, measurement of total porosity, saturated hydraulic conductivity tests, and gas permeability experiments. A similar set of experiments has never been performed before on a single waste sample. From these measurements, constitutive relationships were developed with HYDRUS-1D for refuse samples that assume either a single or dual domains within the media. To simplify method development, the refuse samples consisted entirely of newspaper, which were prepared in two particle sizes and packed to compression cells to replicate typical stress conditions in landfills. The dual permeability model performed significantly better than the single porosity model in fitting the data, suggesting that a dual domain description of these refuse samples was required to describe water flow. Results also indicate that the properties of fracture domain, which characterizes the pores between refuse particles, is affected by the size of waste materials. These experiments confirmed the utility of the laboratory procedures developed for this work, and indicate that laboratory measurements are useful for characterizing the matrix domain of refuse waste samples.
