Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environmental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose ofthis series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environ ment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over 'five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas ofup to 15 million inhabitants produce large quantities ofwaste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.

Unlike existing books of nuclear reactor physics, nuclear engineering and nuclear chemical engineering this book covers a complete description and evaluation of nuclear fission power generation. It covers the whole nuclear fuel cycle, from the extraction of natural uranium from ore mines, uranium conversion and enrichment up to the fabrication of fuel elements for the cores of various types of fission reactors. This is followed by the description of the different fuel cycle options and the final storage in nuclear waste repositories. In addition the release of radioactivity under normal and possible accidental conditions is given for all parts of the nuclear fuel cycle and especially for the different fission reactor types.

Advances in Water Treatment and Pollution Prevention explores the most up-to-date studies in the field of water pollution. More specifically, this book examines the causes and effects of this threatening phenomenon and identifies the preventive measures that can be taken to contain, and even to defeat, water pollution worldwide. The papers gathered in this volume pinpoint the need to implement greener water treatments to prevent water pollution from impacting ecosystems, human well-being and economies any further. They also successfully outline the processes that have been studied, optimized and developed so far to sustain our environment. Advances in Water Treatment and Pollution Prevention will represent a valuable resource to academic researchers, students, institutions, environmentalists, and anyone interested in environmental policies aimed at safeguarding both the quality and the quantity of water.

This book is the second edited compilation of selected, refereed papers submitted to ERTEP 2007. The book is organized into 10 chapters along four of the key themes that were discussed at the conference: Environmental Health Management; Mining and Environment; Environmental Monitoring and Policy Development; and Susta- ability and Social Responsibility. It is hoped that the contents of the book will p- vide an insight into some of the environmental and health management challenges confronting the developing world and the steps being taken to address them. The ?rst three chapters under the Environmental Health and Management theme discusses issues related to food security and related environmental distress in sub- Saharan Africa. Chapter 1 argues that pervasive poverty and low agricultural p- ductivity are important factors in understanding food insecurity in the region, and broader global processes are examined. This chapter maintains that while poverty undermines individual and household access to suf?cient food through market p- chase, land inequalities, corruption, structural adjustment programs, civil con?ict, HIV/AIDS and the role of the World Trade Organization Agreement on Agric- ture are decisive. The authors argue that achieving food security in sub-Saharan Africa requires policies and actions that are integrated with efforts to reduce poverty, enhance livelihoods and incomes and increase agricultural output, while also paying attention to underlying structural factors that bear on agriculture in the region.

The use of renewable bioenergy is increasing, and so is the production of associated wastes: biomass ashes. This book presents eleven chapters on the options for recycling such biomass ashes, ranging from their use as fertilizer in agriculture and forestry to their application as a supplement for the production of cement-based materials or bricks. The book also examines the pros and cons for each of the different uses of biomass ashes.

The packaging industry is under pressure from regulators, customers and other stakeholders to improve packaging s sustainability by reducing its environmental and societal impacts.

Industry case studies are used throughout the book to illustrate possible applications and scenarios." Packaging for Sustainability" draws on the expertise of researchers and industry practitioners to provide information on business benefits, environmental issues and priorities, environmental evaluation tools, design for environment, marketing strategies, and challenges for the future."

Over the last several years, there has been much discussion on the interrelation of CO2 emissions with the global warming phenomenon. This in turn has increased pressure to develop and produce more fuel efficient engines and vehicles. This is the central topic of this book. It covers the underlying processes which cause pollutant emissions and the possibilities of reducing them, as well as the fuel consumption of gasoline and diesel engines, including direct injection diesel engines. As well as the engine-related causes of pollution, which is found in the raw exhaust, there is also a description of systems and methods for exhaust post treatment. The significant influence of fuels and lubricants (both conventional and alternative fuels) on emission behavior is also covered. In addition to the conventional gasoline and diesel engines, lean-burn and direct injection gasoline engines and two-stroke gasoline and diesel engines are included. The potential for reducing fuel consumption and pollution is described as well as the related reduction of CO2 emissions. Finally, a detailed summary of the most important laws and regulations pertaining to pollutant emissions and consumption limits is presented. This book is intended for practising engineers involved in research and applied sciences as well as for interested engineering students.

This book is part of a series of eight providing profession-wide, consensus-based assessment of innovative site remediation and hazardous waste treatment technologies.

Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.

Due to the threat of a possible global climate change and the greenhouse effect caused by constituents of anthropogenic origin in the atmosphere, air quality has become a major environmental issue. As a consequence, emissions into the atmosphere need to be monitored and controlled. Measurement of Atmospheric Emissions presents technologies for emission control and analysis from industrial and energy plants. The author explains the physical and chemical basis before proceeding to the practical performance. This publication provides the reader with the knowledge necessary to critically analyze and investigate emission measurement techniques. It will be of great interest to researchers and engineers in the fields of environmental technology and air pollution control. It will assist in the choice of the most appropriate instruments for various purposes and circumstances.

As the availability of fossils fuels becomes more limited, the negative impact of their consumption becomes an increasingly relevant factor in our choices with regards to primary energy sources. The exponentially increasing demand for energy is reflected in the mass generation of by-products and waste flows which characterize current society's development and use of fossil sources. The potential for recoverable material and energy in these ever-increasing refuse flows is huge, even after the separation of hazardous constituent elements, allowing safe and sustainable further exploitation of an otherwise 'wasted' resource. Fuel Cells in the Waste-to-Energy Chain explores the concept of waste-to-energy through a 5 step process which reflects the stages during the transformation of refuse flows to a valuable commodity such as clean energy. By providing selected, integrated alternatives to the current centralized, wasteful, fossil-fuel based infrastructure, Fuel Cells in the Waste-to-Energy Chain explores how the concept of waste-to-energy can be constructed and developed into a realistic solution. The entire spectrum of current and future energy problems is illuminated through the explanation of the operational, integration and marketing implications of high efficiency technological solutions using the real context of developed regions such as Europe. Up-to-date reviews are provided on the status of technology and demonstration, implementation and marketing perspectives. The detailed technological information and insight gathered from over twenty years of experience in the field makes Fuel Cells in the Waste-to-Energy Chain a valuable resource for all engineers and researchers in the fields of energy supply systems and waste conversion, as well as providing a key reference for discussions by policy makers, marketing experts and industry developers working in energy supply and waste management.

Modern societies produce large amounts of waste of many different types. This presents a problem in terms of management or disposal to prevent harm to human health and the environment. Additionally it represents a loss of potentially useful resources. In the circular economy concept nothing would ever become waste because everything would be re-usable or its components recoverable. Ionic liquids provide a potential route for valorisation of different waste types, paving the way for a circular economy and a more sustainable world. Covering various types of waste, including municipal, industrial, electronic, and medical, while addressing patented and commercial applications, this book aims to deliver a comprehensive, but also critical, perspective on the application of ionic liquids towards waste valorisation. Waste Valorisation Using Ionic Liquids is a useful resource for academic and industrial players, in the fields of chemistry, chemical and environmental engineering, and biotechnology, as well as anyone working on waste management and resource recovery.

Ion-exchange Technology II: Applications presents an overview of the numerous industrial applications of ion-exchange materials. In particular, this volume focuses on the use of ion-exchange materials in various fields including chemical and biochemical separations, water purification, biomedical science, toxic metal recovery and concentration, waste water treatment, catalysis, alcohol beverage, sugar and milk technologies, pharmaceuticals industry and metallurgical industries. This title is a highly valuable source not only to postgraduate students and researchers but also to industrial R&D specialists in chemistry, chemical, and biochemical technology as well as to engineers and industrialists.

The series Advances in Industrial Control aims to report and encourage technology transfer in control engineering. The rapid development of control technology impacts all areas of the control discipline. New theory, new controllers, actuators, sensors, new industrial processes, computer methods, new applications, new philosophies..., new challenges. Much of this development work resides in industrial reports, feasibility study papers and the reports of advanced collaborative projects. The series offers an opportunity for researchers to present an extended exposition of such new work in all aspects of industrial control for wider and rapid dissemination. The environmental aspects of all of our society's activities are extremely important if the countryside; the sea and wildernesses are to be fully enjoyed by future generations. Urban waste in all its manifestations presents a particularly difficult disposal problem, which must be tackled conscientiously to prevent long lasting damage to the environment. Technological solutions should be seen as part of the available options. In this monograph, the authors M. R. Katebi, M. A. Johnson and J. Wilkie seek to introduce a comprehensive technological framework to the particular measurement and control problems of wastewater processing plants. Of course the disposal of urban sewage is a long-standing process but past solutions have used options (disposal at sea) which are no longer acceptable. Thus to meet new effluent regulations it is necessary to develop a new technological paradigm based on process control methods, and this is what the authors attempt to provide.

Development of environmentally friendly products gains an increasing - portance in science and in industry. While product development was strongly dedicated to achieve quality, cost and time targets, environmental issues indirectly had always been under consideration by engineers, see Fig. 1. Furthermore a methodology for the development of environm- tally sound products was missing. Despite of significant progress in using computer aided tools for product development and design, environmental aspects were attended. Computer aided tools typically do not include methods for considering environmental issues enabling the designer to - sess a product's environmental effects. Fig. 1. Vision of Environment as a key target for product development v vi Preface Product related environmental issues are getting more and more political and public awareness. Development of environmentally friendly products has become an action item for both, politics and industry (UNFCCC 1997). Energy consumption is on the agenda and covers pollution and resource saving. Typical topics of directives of the European Union are waste, noise, air pollution, water, nature and biodiversity, soil protection, civil protection and climate change. After the translation into national law the development of environmentally friendly products is a basic approach to contribute to the fulfilment of the topics mentioned above. In the European Community a "Communication from the Commission to the Council and the European Parliament" on "Integrated Product Policy" was adopted on th 18 June 2003 (EC 2003).

This monograph consists of manuscripts submitted by invited speakers who participated in the symposium "Industrial Environmental Chemistry: Waste Minimization in Industrial Processes and Remediation of Hazardous Waste," held March 24-26, 1992, at Texas A&M University. This meeting was the tenth annual international symposium sponsored by the Texas A&M Industry-University Cooperative Chemistry Program (IUCCP). The program was developed by an academic-industrial steering committee consisting of the co-chairmen, Professors Donald T. Sawyer and Arthur E. Martell of the Texas A&M University Chemistry Department, and members appointed by the sponsoring companies: Bernie A. Allen, Jr., Dow Chemical USA; Kirk W. Brown, Texas A&M University; Abraham Clearfield, Texas A&M University; Greg Leyes, Monsanto Company; Jay Warner, Hoechst-Celanese Corporation; Paul M. Zakriski, BF Goodrich Company; and Emile A. Schweikert, Texas A&M University (IUCCP Coordinator). The subject of this conference reflects the interest that has developed in academic institutions and industry for technological solutions to environmental contamination by industrial wastes. Progress is most likely with strategies that minimize waste production from industrial processes. Clearly the key to the protection and preservation of the environment will be through R&D that optimizes chemical processes to minimize or eliminate waste streams. Eleven of the papers are directed to waste minimization. An additional ten papers discuss chemical and biological remediation strategies for hazardous wastes that contaminate soils, sludges, and water.

The term "hazardous wastes" covers a wide range of disused products and production wastes generated not only in industrial sectors, but also in all areas of everyday life. Hazardous wastes are to a large extent shipped by sea to third countries for recycling or disposal. While the procedural requirements for such movements are laid out in the 1989 Basel Convention, explicit rules of responsibility and liability for resulting damages are neither provided by the Basel Convention nor by other international conventions. The Liability Protocol to the Basel Convention of 1999 has not yet entered into force. This book examines the existing rules of responsibility and liability applying to States and private persons and outlines the conditions under which liability may be incurred. Subsequently, the advantages and shortcomings of the 1999 Liability Protocol are analyzed. Although this Protocol faces substantial political headwind, from a legal perspective it includes principally useful and reasonable approaches and should therefore be ratified.

Solid waste management is currently a major issue worldwide with numerous areas reaching critical levels. Many developing countries and countries in transition still miss basic waste management infrastructure and awareness. It is here that many of the solid waste management problems and challenges are currently being faced. As such, waste-to-energy (WTE) consists of a proven and continuously developing spectrum and range of technologies in a number of (mostly) developed countries. However, it's integration in developing countries and systems in transition is often faced with scepticism and a complex set of barriers which are quite unique and differ greatly from those where WTE has been validated and applied over the years. Waste-to-Energy: Opportunities and Challenges for Developing and Transition Economies will address this issue both theoretically and using concrete examples, including: * contributions from numerous scholars and practitioners in the field, * useful lessons and rules of thumb, * both successful and failed cases, and * real-life examples and developments. Waste-to-Energy approaches this dynamic aspect of environmental engineering and management in a methodical and detailed manner making it an important resource for SWM planners and facility operators as well as undergraduate and post graduate students and researchers.
