Concern about the fate of waste products produced by a wide range of industrial processes has led to the realization that they may have potential uses and, therefore, value. In an effort to develop more sustainable processes and reduce waste storage, the use of waste as a resource has been gaining attention worldwide. Consequently, there have been a large number of studies aimed at utilizing such wastes. Conversion of Large Scale Wastes into Value-added Products discusses various selected classes of large-scale waste and their current applications and potential future applications.
This book provides a snapshot of a continually evolving field, which includes both well-established processes and a drive toward developing strategies for new applications of wastes. The first chapter provides a general introduction to the area of large-scale waste utilization, including drivers for waste recovery, and secondary processes and products for waste reuse. Subsequent chapters discuss applications and potential applications in specific classes of large-scale waste:

• Various types of waste generated from different metal processing operations
• Waste generated by coal combustion, a major source of power generation that produces enormous quantities of waste
• Waste electrical and electronic equipment, important for recycling finite resources and reducing health and environmental risks
• Food waste, a significant and diverse waste stream with economic and environmental impacts

The final chapter presents a general conclusion to the broad subject of waste utilization, summarizing the topics and addressing future trends in waste research.

This volume is designed to give local government elected officials and their staff the background information they need on the state of the art in small scale municipal waste-to-energy project development. It will, of course, be of interest to many others in the field. The small-scale segment of the municipal waste energy recovery industry has grown and changed in many ways in recent years. With increasingly stringent environmental regulations pushing up the costs of landfilling, as well as today's higher prices for oil and natural gas, the economics of small-scale systems are attractive to smaller communities or counties which might at one time only have considered joining a multijurisdictional large-scale project. The difficulties involved in devel oping a project that envelops numerous governmental entities are discouraging, and a small, local project may be more readily achievable. Gershman, Brickner & Bratton, Inc. hopes this book will be of assistance to those who are considering such a project, providing guidance and encouragement, as well as practical information on technologies, eco nomics, energy markets, financing, environmental issues, and the pitfalls of project development."

Sampllng Fundamental Aspects 2 Sampling: Fundamental aspects Reimar Leschber Institut fuer Wasser-, Boden- und Lufthygiene des Bundesge- sundheitsamtes, Berlin-Dahlem, Federal Republic of Germany Chairman of Working Party 2, COST 681 Protection of the environment increasingly requires the de- velopment of a recycling society using 'secondary raw ma- terials' instead of natural resources wherever possible. Among the methods of recycling the agricultural use of sludge is a traditional one and a good example with a long history of a meanlngful use of waste material. Increasing demands of water pollution control in the last de- cades leading to intensified and extended sewage treatment processes and thus to an increase of the sludge quantity have caused problems in this field in general. In addition, there were local problems of industrial pollution which have led to an increase of harmful substances in municipal sewage sludges. So, when the Concerted Action COST 68 was set up to study the beneficial and harmful effects of the agricultural use of sludge, investigation of harmful substances in the sludges and their environmental effects was 9ne of the main tasks of work. Although the progress of analytical techniques enabled the environmental authorities and institutions to determine harmful substances in sludges with great accuracy, it became clear that unsatisfactory results and an incomplete reproduc- ibility of analytical findings often were not due to shortcom- ings in the analytical procedure itself but to a preceding in- vestigation step: Improper sampling and sample preparation.

Five billion people, at present the world population, inevitably affect the quality of the environment. The general public in an increasing number of countries is getting more and more concerned about this deterioration in quality. As a result many people cast doubts upon the desirability of the increase in energy consumption, the production of superfluous goods, ever-growing waste flows, harmful emissions of industrial processes, and so on. Actually, no one can simply ignore these issues. For instance, the authorities could introduce more environmental legislation aiming at a healthy environment; industries could change to cleaner production processes; the public at large should assume an even more conservation-minded attitude rather than confine themselves to shaking a finger at 'the industry'. In short, in all sectors of society there are often numerous ways and means of curbing environmental pollution. Clearly, environmental technology - the development and application of techniques to identify, quantify and reduce environmental problems - can make a substantial contribution here in many situations. Until now a large number of such new techniques have been developed. Many of these techniques not only appear to add greatly to reducing the burden on the environment, they sometimes also offer interesting economic advantages (savings in raw material and energy, etc.).

Solid waste is a major urban challenge worldwide and decisions over which technologies or methods to apply can have beneficial or detrimental long-term consequences. Inappropriate management of solid waste can lead to damaging environmental impacts, particularly in the megacities of the Global South. Urban Recycling Cooperatives explores the multiple narratives and interdisciplinary nature of waste studies, drawing attention to the pressing social, economic and environmental challenges related to waste management. The book asks questions such as: how do we define waste and our relation to it; who is involved in dealing with waste; and what power interactions become manifest over issues of accessing and managing waste? In recent years informal cooperatives have emerged, devoted to recycling household and business waste before reclassifying it and redirecting it to the authorities. Hence, these workers are able to reclaim significant amounts of natural resources and thus contribute to the saving of resources and lessened waste management expenditures. With particular reference to the Brazilian megalopolis of Sao Paulo, this book describes this paradigm shift in the general understanding of waste as unwanted discard towards the recognition of waste as a resource that must be recovered for reuse or recycling. It would be of interest to students and policy makers working in international development and waste management.

Landfilling of waste has increased dramatically over recent years and there have been many examples of landfills which are unacceptable on environmental and health grounds. This is one of a group of international reference books which address this problem, specifically in this case covering the strongly contaminated wastewater developed from landfills.

Biofilms represent the natural living style of microbial communities and play a pivotal role in biogeochemical cycles and natural attenuation. Biofilms can be engineered for biodegradation and biotransformation of organic and inorganic contaminants, for both in situ bioremediation and ex situ treatment in bioreactors. This book focuses on microbial biofilms and their potential technological applications for sustainable development. It covers recent advances in biofilm technologies for contaminant remediation coupled to recovery of resources and serves as a complete reference on the science and technology behind biofilm mediated bioremediation and wastewater treatment.

A successful modern heavy metal control program for any industry will include not only traditional water pollution control, but also air pollution control, soil conservation, site remediation, groundwater protection, public health management, solid waste disposal, and combined industrial-municipal heavy metal waste management. In fact, it should be a total environmental control program. Comprehensive in scope, Heavy Metals in the Environment provides technical and economical information on the development of a feasible total heavy metal control program that can benefit industry and local municipalities. The book discusses the importance and contamination of metals such as lead, chromium, cadmium, zinc, copper, nickel, iron, and mercury. It covers important research of metals in the environment, the processes and mechanisms for metals control and removal, the environmental behavior and effects of engineered metal and metal oxide nanoparticles, environmental geochemistry of high arsenic aquifer systems, nano-technology applications in metal ion adsorption, biosorption of metals, and heavy metal removal by expopolysaccharide-producing cyanobacteria. The authors delineate technologies for metals treatment and management, metal bearing effluents, metal-contaminated solid wastes, metal finishing industry wastes and brownfield sites, and arsenic-contaminated groundwater streams. They also discuss control, treatment, and management of metal emissions from motor vehicles. The authors reflect the breadth of the field and draw on personal experiences to provide an in-depth presentation of environmental pollution sources, waste characteristics, control technologies, management strategies, facility innovations, process alternatives, costs, case histories, effluent standards, and future trends for each industrial or commercial operation. The methodologies and technologies discussed are directly applicable to the waste management problems that must be met in all industries.

Waste incineration is finding increasing favour as a waste disposal method and this Issue considers the topic of waste disposal and the place of incineration as an option. It reviews the emissions and environmental impacts of incineration and available control technologies, specific research upon emissions of trace metals and organic micropollutants, and the methodologies for environmental impact assessment. There is currently great interest and considerable controversy over waste incineration and this book gives a dispassionate view of the scientific and technical issues involved. It provides a broad overview of the role incineration can play in waste management and looks at how environmental impacts may be managed and assessed. For municipal waste, when coupled with energy recovery, waste incineration provides an efficient, spatially compact means of bulk waste reduction, which is widely favoured over landfill, and for some chemical wastes, provides the only presently viable disposal option. This book places incineration in the context of other waste disposal options and examines the relative benefits and environmental impacts in a balanced way.

Selenium (Se) pollution has led to several cases of severe aquatic ecosystem deterioration due to Se poisoning caused by bioaccumulation over time. However, the removal of selenate (SeO42-) from wastewater streams with co-contaminants has been largely considered as a black box in anaerobic biological systems using mixed consortia. This research aimed at addressing the effect of wastewater characteristics, i.e. co-contaminants such as nitrate (NO3-) and sulfate (SO42-), heavy metals and pH, on the biological reduction of SeO42- and evaluating process integration for Se-laden wastewater treatment with co-contaminants. This study demonstrated that the presence of co-contaminants can actually be beneficial for Se removal provided that the concentrations are carefully monitored and appropriate operating conditions and process configurations are used. The Se removal (total Se and SeO42-) efficiency increased by ~30% in the presence of NO3- and/or SO42- compared to systems with SeO42- alone. Additionally, an integrated process of an ion exchange (IX) column and bioreactors showed improved overall removal capacity for SO42- and total Se. The knowledge and information gained from this research can help in the advancement and application of biological processes, i.e. predicting of reactor performance, solving specific design or practical problems and implementing novel treatment techniques for Se-laden mine wastewater.
