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

Converting old landfills to energy producing sites, while capturing emitted greenhouse gases, has faced numerous technical, financial and social challenges and developments lately. Also, the re-mining of landfills to recover useful land in dense urban areas and proper landfill closure has been a subject of discussion and investigation. Designed as an overview text for landfill management from cradle to grave, this volume’s content stretches from the fundamentals to the rather indepth details. By putting down their joint international experience, the authors have intended to both guide and inspire the user for his or her landfill project. Introducing the fundamental concepts of landfill gas management and its needs and importance in the present world energy scenario, this accessible reference volume presents key landfill gas management techniques at regional, national and global levels. In detail, it gives an account of the recent technologies available for landfill gas treatment and its utilization. It summarizes landfill gas prediction models developed in various parts of the world and details their adequacy in various field conditions. Covering both landfill remediation aspects and economic considerations while selecting a landfill gas to energy utilization project, the reader gets familiar with the practical aspects of converting a landfill site. Also, the challenges faced by municipalities and landfill operators in recovering landfill gas as an energy source are described, and solutions are suggested for solving them effectively. These include practical execution problems, governmental issues, and developing policies to encourage investment. The volume also includes various case studies of landfill gas-to-energy utilization projects from around the world, which can be reviewed and customized for the reader’s own application with the help of extensive reference section. Intended as an overview text for advanced students and researchers in the relevant engineering and technology fields (Environmental, Civil, Geotechnical, Chemical, Mechanical and Electrical), this book will also be particularly helpful to practitioners such as municipal managers, landfill operators, designers, solid waste management engineers, urban planners, professional consultants, scientists, non-governmental organizations and entrepreneurs.

In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.

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.

Understanding, quantifying, and tracking atmospheric methane and emissions is essential for addressing concerns and informing decisions that affect the climate, economy, and human health and safety. Atmospheric methane is a potent greenhouse gas (GHG) that contributes to global warming. While carbon dioxide is by far the dominant cause of the rise in global average temperatures, methane also plays a significant role because it absorbs more energy per unit mass than carbon dioxide does, giving it a disproportionately large effect on global radiative forcing. In addition to contributing to climate change, methane also affects human health as a precursor to ozone pollution in the lower atmosphere. Improving Characterization of Anthropogenic Methane Emissions in the United States summarizes the current state of understanding of methane emissions sources and the measurement approaches and evaluates opportunities for methodological and inventory development improvements. This report will inform future research agendas of various U.S. agencies, including NOAA, the EPA, the DOE, NASA, the U.S. Department of Agriculture (USDA), and the National Science Foundation (NSF).
