Shows why plastics, in aggregate, have become a toxin to humans, wildlife, and the planet, and proposes novel solutions that involve neither traditional recycling nor giving up plastic. "Plastics!" In the 50 years since Dustin Hoffman's character in The Graduate was instructed that this was the career field of the future, we have not been able to escape this ubiquitous but poorly understood material. Author Jack Buffington argues that the plastics crisis is careening toward a tipping point from which there will be no return. There is still time, however, to do something about this crisis if we have the imagination and the will to move away from the failed policies of the past. This book is the first to propose a new model for linking our synthetic world to the natural one, rather than seeking to treat them as separate entities. The key is supply chain innovation. Buffington presents five market-based solutions based on this principle that will allow consumers to continue to use plastic, which has in many ways enabled our way of life. Alongside these proposed solutions, he also addresses the proliferation of plastic as we know it-growth that, if left unchecked, will lead to a "planetary crisis," according to the United Nations-and considers how the material itself might be adapted for a sustainable future. Provides a realistic solution for our use of plastic: not to eliminate it, but to innovate it Views plastic not only as a known environmental and health hazard but as a material critical to our future and therefore worth revising for future use Explains what we must do-and by when-in order to be able to keep using plastic without harming the planet or our health Shows the links between the environmental, toxicological, and socioeconomic challenges in our use of plastic, and how these dangers can be remedied by supply chain innovation Introduces two significant disruptive innovations that if implemented, will save us from the growing problem posed by synthetics

Electronic waste, which includes everything from refrigerators to smartphones, is one of the world's fastest growing waste streams. Often these items are simply discarded as new technology becomes available. A huge amount of electronic waste is generated globally and currently only around 20% of it is recycled. The complex mixture of materials and components within electronic waste makes it difficult to manage and many of these components can pose hazards to human health or the environment if not disposed of carefully. There have been significant changes in the global approach to electronic waste management and the legislation around it since the publication of the first edition of Electronic Waste Management. This new edition provides an updated overview across the world as well as presenting new chapters on current issues in recycling and management of this waste. This is an essential reference not only for those working in recycling and waste management, but also for those working in manufacturing and product development who wish to consider the full lifecycle of their products. It also provides valuable insights for policymakers developing more environmentally sound and sustainable systems and strategies for the management of electronic waste.

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.

This title includes a number of Open Access chapters. This compendium volume contains the most current technical and economic analyses of emerging waste disposal strategies. The editor, a well-respected researcher in this field, has selected articles that will be valuable to readers who range from engineers and academics to decision-makers in both the public and private sectors. Several international case studies give practical applications and examples of the various technologies and approaches. A final section discusses policy planning for the future.

This title includes a number of Open Access chapters. This new book provides a multiperspective look at research into many elements of remediating environmental hazards connected to sewage and landfill leachate. Sewage and landfill leachate treatments include various processes that are used to manage and dispose of the liquid portions of solid waste. Untreated leachate and sewage are hazards to the environment if they enter the water system. The goal of treatment is to reduce the contaminating load to the point that leachate and sewage liquids may be safely released into groundwater, streams, lakes, and the ocean. Around the world, however, huge volumes of contaminated water from sewage and landfill leachate is still pumped directly into water systems, especially in the world's developing nations. Aside from the damage to marine environments and fisheries that this causes, it also jeopardizes the world's vulnerable water resources. This compendium volume explores effective sewage management, which is essential for nutrient recycling and for maintaining ecosystem integrity. It looks at a range of technologies that are available for the treatment of sewage and landfill leachate. The editor, himself a respected and experienced researcher in this field, includes chapters that cover biological treatments, reverse osmosis, and chemical-physical processes. This volume offers important research that will help us both assess our existing treatment facilities, as well as build better, more effective ones for the future.

Heavy metals, such as lead, chromium, cadmium, zinc, copper, and nickel, are important constituents of most living organisms, as well as many nonliving substances. Some heavy metals are essential for growth of biological and microbiological lives, yet their presence in excessive quantities is harmful to humans and interferes with many environmental processes. Heavy metals are also nonbiodegradable, making them more difficult to remediate. Decontamination of Heavy Metals: Processes, Mechanisms, and Applications tackles the subject of heavy metals in the environment, with special emphasis on their treatment, removal, recovery, disposal, management, and modeling.

Concepts, Cutting-Edge Technologies, and Applications

The book provides in-depth coverage of the major hazardous heavy metals that are found in water, land, and facilities and that have significant effects on public health and the environment. After an overview of heavy metal contamination, the text reviews the concepts and technologies of pollution prevention. It then examines technologies for metal decontamination, ranging from precipitation which is the most commonly used to cutting-edge technologies such as precipitation-crystallization, ion exchange, membrane filtration, and electrolysis. Mathematical models for metal removal and recovery are also included.

A comprehensive handbook for environmental professionals, researchers, and students, it provides technical information to help readers develop a feasible total metal control program that can benefit both industry and local municipalities.

This book critically examines the phenomenon of low level radioactive waste (LLRW) disposal facility siting across four international democracies. The issue is of growing importance since World War II the level of this waste has increased from the hundreds to the billions. The International Atomic Energy Agency estimates that nuclear power generation facilities alone produce about 200,000 cubic meters of low and intermediate-level waste each year worldwide; waste that needs to be isolated from the public for extended periods of time. Siting LLRW disposal facilities in democracies is beset by two main problems: almost universally negative community response to siting proposals, and, as a result, government s reactive policies. There has been a tendency for democratic countries to adopt a default position of deferring siting decisions for as long as possible due to a fear of public opposition, which only increases the risks associated with radiation.

The authors explore these issues utilizing a linear narrative case study approach that critically examines key stakeholder interactions in order to explain how siting decisions are made. The book incorporates a stakeholder theory approach to allow for a better understanding of the key players roles and how such decisions are made as well as an environmental justice perspective to better understand how some siting decisions negatively impact lower socio-economic classes and indigenous peoples within democratic societies. The four featured countries the United States, Australia, Spain and South Korea represent a broad range of current siting issues. Though the different countries are geographically and culturally diverse, they are all democracies with vibrant civil societies, which mean that siting decisions require negotiation between the siting authority and the host community via representative stakeholders. Most studies of nuclear waste focus on siting at a single location or in a single country, whereas this book seeks to establish an understanding of the political, economic, environmental, legal and social dimensions of siting across multiple countries. Furthermore, the book targets specifically low-level radioactive waste, which has traditionally received far less study by the academic community than high-level waste and spent nuclear fuel. This valuable resource fills a gap in the literature with international comparative research and provides recommendations for future low-level radioactive waste disposal facility siting efforts.

The book should be of interest to students and scholars of environmental law, justice, management and politics, as well as energy and security policy."

Increasingly stringent regulation of pollution and waste production worldwide drives the need to isolate contaminants that pose a threat to human and environmental health by using engineered barrier systems involving the use of low permeable materials. Over the past two decades, geosynthetic clay liners have gained widespread acceptance for use in such barrier systems. They are often used as a component of primary and secondary base liners or final cover systems in municipal solid-waste landfills as well as in regulated industrial storage and mining waste-disposal facilities. This book gives a comprehensive and authoritative review of the current state of practice on geosynthetic clay liners in waste containments. It provides an insight into individual materials (bentonite and the associated geosynthetics) and the manufacturing processes. This is followed by the coverage of important topics such as hydraulic conductivity, chemical compatibility, contaminant transport, gas migration, shear strength and slope stability, and field performance.

WINNER: 2020 International Solid Waste Association Publication Award Among other factors, rapid global population growth, our development model and patterns of production and consumption have increased waste generation worldwide to unsustainable rates. This rise has led to crises in many countries where waste management practices are no longer sound. Global Waste Management outlines the emerging global waste crisis considering the perspectives of developed and developing countries around the world and the international relationships between them. This book provides an ecological viewpoint as well as studying these problems from a legal and justice standpoint. Global Waste Management contextualises the problems faced when dealing with waste including the causes and origins. Focus is given to cross border waste transfer, as an ongoing and controversial practice, making waste management a global matter. This book scrutinizes existing international, European and Brazilian regulation on waste to highlight the complexity of the subject and the weaknesses of the law. Using a critical and socio-ecological approach, the book proposes an original model of governance to support a new system of global waste management that takes into account ecological sustainability and social justice to overcome the waste crisis. To create these models, a theoretical framework on socio-ecological justice is developed and combined with different discourses and theories described throughout the book. This is the essential guide to understanding the global waste crisis and the future of waste management.
