Biotechnology for Treatment of Wastes Containing Metals addresses various aspects related to different wastes that have a metallic content and represent a serious risk for the environment and human health. These wastes, due to their physical and chemical characteristics, have been the object of studies which have led to the development of different technologies in recycling, reuse or adequate disposal, biotechnology being one of these alternatives. Biotechnology offers a range of options for the treatment of types of waste using microorganisms, biomass and their by-products. The mechanisms involved in these waste treatment processes are diverse and complex, and its optimization and efficiency is multifactorial. This text contains nine chapters related to the problem of the metal contamination in the environment as well as some of the different biotechnological alternatives that have been applied for the reduction and/or recovery of metal contamination.

Bringing together the research of 62 distinguished scientists in one volume, Environmental Contamination: Health Risks and Ecological Restoration offers a comprehensive view of the remediation of contaminated land. A one-stop resource, it covers historical and emerging contaminants, the issues of bioavailability of chemicals and their associated human health risks, and the latest remediation technologies. The book also contains numerous case studies, many of them drawn from the Asia-Pacific region, that look at the effects of rapid industrialization. The chapters are inspired by presentations and discussions held during the 2010 Croucher Advanced Study Institute workshop, entitled Remediation of Contaminated Land-Bioavailability and Health Risk. With the speed and scale of recent socioeconomic development, particularly in regions with less stringent environmental regulations, it is evident that various industrial activities have given rise to tremendous environmental degradation and severe health problems. The book begins with a description of current problems and future trends of pollutants, as well as their impact on the environment and human health. It then focuses on emerging contaminants, such as flame retardants and electronic waste. The book also examines research on environmentally friendly and sustainable solutions to remediate contaminated lands, exploring cutting-edge bioremediation and phytoremediation technologies. Chapters discuss arsenic biomethylation, copper homeostasis, microbial transformation of phthalate esters, the potential function of paddy fields in phytoremediation, the use of constructed wetlands for pollution control, phytostabilization of arsenic-contaminated sites, and more. This timely book provides readers with a highly focused reference on some of the most urgent environmental and health issues and research topics.

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

Millions of tonnes of waste are produced every year by the agri-food industry. Disposal by landfill or incineration is already expensive and the industry faces increasing costs for the removal of refuse and remnants. The costs of energy and water are also significant for food businesses and savings can be made in these areas if the quantity of energy and water used is limited. Methods to recycle and reduce the need for disposal are therefore increasingly of interest.

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.

Communication and stakeholder involvement are essential components for a successful disposal programme. Experience around the world suggests that the scientific and technological bases for the safe disposal of radioactive waste are available — disposal solutions exist or can be developed based on established knowledge. However, concerns and opposition among the public and other stakeholders could slow or even prevent the implementation of needed disposal solutions. This publication provides practical guidance on communication and stakeholder involvement for countries embarking on, relaunching or revising a disposal programme. It draws upon past experiences and emphasizes that practical implementation requires adjusting to the evolving context as given by the national, social and political circumstances. The primary intended users of this publication include those working in the field of radioactive waste management in government, regulatory bodies and industry, an especially in organizations responsible to implement solutions for radioactive waste disposal.

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."

Polycyclic Aromatic Hydrocarbons (PAHs) are a group of semi-volatile organic compounds that are formed during the incomplete burning of gas, coal, oil, wood, garbage, or other organic substances. PAHs are a concern because a number of them have been identified as genotoxic and/or carcinogenic. They pose a threat to ecological systems and can cause health problems. A significant source of PAHs is the effluent of wastewater treatment plants. This book explores the occurrence and the treatability of PAHs in wastewater treatment.

A practical, systems-based approach for a more sustainable farming operation To many people today, using the words "factory" and "farm" in the same sentence is nothing short of sacrilege. In many cases, though, the same sound business practices apply whether you are producing cars or carrots. Author Ben Hartman and other young farmers are increasingly finding that incorporating the best new ideas from business into their farming can drastically cut their wastes and increase their profits, making their farms more environmentally and economically sustainable. By explaining the lean system for identifying and eliminating waste and introducing efficiency in every aspect of the farm operation, The Lean Farm makes the case that small-scale farming can be an attractive career option for young people who are interested in growing food for their community. Working smarter, not harder, also prevents the kind of burnout that start-up farmers often encounter in the face of long, hard, backbreaking labor. Lean principles grew out of the Japanese automotive industry, but they are now being followed on progressive farms around the world. Using examples from his own family's one-acre community-supported farm in Indiana, Hartman clearly instructs other small farmers in how to incorporate lean practices in each step of their production chain, from starting a farm and harvesting crops to training employees and selling goods. While the intended audience for this book is small-scale farmers who are part of the growing local food movement, Hartman's prescriptions for high-value, low-cost production apply to farms and businesses of almost any size or scale that hope to harness the power of lean in their production processes.
