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.

Solid Waste Landfilling: Concepts, Processes, Technology provides information on technologies that promote stabilization and minimize environmental impacts in landfills.

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

• New York Times bestseller • The 100 most substantive solutions to reverse global warming, based on meticulous research by leading scientists and policymakers around the world “At this point in time, the Drawdown book is exactly what is needed; a credible, conservative solution-by-solution narrative that we can do it. Reading it is an effective inoculation against the widespread perception of doom that humanity cannot and will not solve the climate crisis. Reported by-effects include increased determination and a sense of grounded hope.” —Per Espen Stoknes, Author, What We Think About When We Try Not To Think About Global Warming “There’s been no real way for ordinary people to get an understanding of what they can do and what impact it can have. There remains no single, comprehensive, reliable compendium of carbon-reduction solutions across sectors. At least until now. . . . The public is hungry for this kind of practical wisdom.” —David Roberts, Vox “This is the ideal environmental sciences textbook—only it is too interesting and inspiring to be called a textbook.” —Peter Kareiva, Director of the Institute of the Environment and Sustainability, UCLA In the face of widespread fear and apathy, an international coalition of researchers, professionals, and scientists have come together to offer a set of realistic and bold solutions to climate change. One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. If deployed collectively on a global scale over the next thirty years, they represent a credible path forward, not just to slow the earth’s warming but to reach drawdown, that point in time when greenhouse gases in the atmosphere peak and begin to decline. These measures promise cascading benefits to human health, security, prosperity, and well-being—giving us every reason to see this planetary crisis as an opportunity to create a just and livable world.

Sustainable Food Waste-to-Energy Systems assesses the utilization of food waste in sustainable energy conversion systems. It explores all sources of waste generated in the food supply chain (downstream from agriculture), with coverage of industrial, commercial, institutional and residential sources. It provides a detailed analysis of the conventional pathways for food waste disposal and utilization, including composting, incineration, landfilling and wastewater treatment. Next, users will find valuable sections on the chemical, biochemical and thermochemical waste-to-energy conversion processes applicable for food waste and an assessment of commercially available sustainable food waste-to-energy conversion technologies. Sustainability aspects, including consideration of environmental, economic and social impacts are also explored. The book concludes with an analysis of how deploying waste-to-energy systems is dependent on cross-cutting research methods, including geographical information systems and big data. It is a useful resource for professionals working in waste-to-energy technologies, as well as those in the food industry and food waste management sector planning and implementing these systems, but is also ideal for researchers, graduate students, energy policymakers and energy analysts interested in the most recent advances in the field. - Provides guidance on how specific food waste characteristics drive possible waste-to-energy conversion processes - Presents methodologies for selecting among different waste-to-energy options, based on waste volumes, distribution and properties, local energy demand (electrical/thermal/steam), opportunities for industrial symbiosis, regulations and incentives and social acceptance, etc. - Contains tools to assess potential environmental and economic performance of deployed systems - Links to publicly available resources on food waste data for energy conversion

Landfilling has been and still remains an important means of municipal solid waste management but it poses a threat to the purity of the environment, especially air. In the coming years, a radical decline in the share of landfilling in waste disposal practices should not be expected. However, this is not to say that people are powerless in the face of the emission of harmful gases into the atmosphere, the spread of bioaerosols and odors. There are many ways of preventing the negative impact of landfills or protecting the environment against such an impact. Some of these preventive and protective measures are described in Mitigation of Landfill Gas Emissions. Special attention is given to the application of anaerobic, aerobic and semi-aerobic bioreactor landfills for control of landfill gas emission. Different types of biotic systems for the oxidation of methane and trace gases, such as biocovers, biofilters, and biowindows, are also presented.

Increasing global consumerism and population has led to an increase in the levels of waste produced. Waste to energy (WTE) conversion technologies can be employed to convert residual wastes into clean energy, rather than sending these wastes directly to landfill. Waste to energy conversion technology explores the systems, technology and impacts of waste to energy conversion.Part one provides an introduction to WTE conversion and reviews the waste hierarchy and WTE systems options along with the corresponding environmental, regulatory and techno-economic issues facing this technology. Part two goes on to explore further specific aspects of WTE systems, engineering and technology and includes chapters on municipal solid waste (MSW) combustion plants and WTE systems for district heating. Finally, part three highlights pollution control systems for waste to energy technologies.Waste to energy conversion technology is a standard reference book for plant managers, building engineers and consultants requiring an understanding of WTE technologies, and researchers, scientists and academics interested in the field. - Reviews the waste hierarchy and waste to energy systems options along with the environmental and social impact of WTE conversion plants - Explores the engineering and technology behind WTE systems including considerations of municipal solid waste (MSW) its treatment, combustion and gasification - Considers pollution control systems for WTE technologies including the transformation of wast combustion facilities from major polluters to pollution sinks
