The last two decades have seen unprecedented developments in marine science and technology. Large scale, international long-term scientific programmes have emerged for monitoring the state of the ocean environment and the rapid development of the offshore oil industry has provided the technological means for a range of other maritime developments. The purpose of this book is to review key developments in this field. Three major themes are developed throughout the book: the key importance of technical developments in ocean management; the application of these developments to specific sea uses ranging from fish farming to the deep sea disposal of industrial waste; and the long term general issues raised - and to some extent solved - by science and technology. This book should be of interest to students and professionals involved in maritime studies, oceanography, offshore engineering and environmental science.

Wastes generated in a community can be a valuable energy and material resource. However, past and current waste disposal and treatment practices consume energy and have led this resource to become a serious environmental burden. Fortunately, being a resource as well as a burden has generated some extremely creative and economically attractive waste-to-energy systems to utilize wastes while mitigating their environmental impact. It is hoped that this book will promote an appreciation of the environmental problems, energy demand and resources, the economics and risks involved that are essential to define the role of these systems in the future. The problems of urban air pollution, acid rain, global greenhouse effect and surface and groundwater degradation all can be tied directly or indirectly to how we produce and utilize energy and dispose of wastes. All communities have wastes, be they wastewater, municipal solid wastes, industrial or agricultural wastes, and the community must deal with them. It is possible to consolidate many of these wastes to gain real benefits in terms of the environment, economics, energy supply and conservation and materials recovery. This text summarizes s

Discharge of nutrient rich wastewater causes eutrophication of surface water; therefore wastewater treatment before discharge is required. Wastewater stabilization ponds are low cost technology used by developing countries but not effective in nitrogen removal due to low nitrifier biomass in the water column. Introduction of surface area for attachment of nitrifiers has therefore been proposed. This thesis reports the performance of pilot scale wastewater stabilization ponds fitted with baffles. The effect of baffles on nitrogen removal under tropical and two operational conditions was investigated. Under TKN/BOD ratio of 0.67, the baffled ponds performed better in nitrogen removal than the control pond. Total nitrogen mass balances showed that nitrification-denitrification, algal uptake and sedimentation were principle nitrogen removal mechanisms in biofilm waste stabilization ponds This study shows the potential of biofilms in improving nitrogen removal in wastewater stabilization ponds. The BOD and TSS concentrations were sufficiently low to permit for reuse in irrigation. If the objective is reuse and optimization of resources, the effluents from the ponds had sufficient nitrogen content for use in agriculture.

This book, designed to assist industrial engineers and managers in making changes in purchasing, manufacturing, and waste handling practices to reduce the costs and liabilities of waste disposal, begins by defining waste minimization in the first two chapters. A description of the economic and regulatory incentives a company has for setting up a waste minimization program follows, and unsuccessful projects are related. Based on these experiences, a method is outlined for companies to use to establish a waste minimization program and implement individual projects.

This study provides a detailed historical account of the policy and practice of radioactive waste management in Britain, Sweden and the Federal Republic of Germany. In their differing approaches, these three countries define the parameters of civil nuclear strategy in Europe. The comparative analysis of the evolution of policy clarifies the context of political and technical decision-making. Assessing the varying degrees of influence which the public, the industry and the government exercise over these actions, Frans Berkhout applies the concept of boundaries of "control", questioning the extent to which such control can be relinquished. This analysis of nuclear strategy, the politics of nuclear power and the shifting emphasis of government regulations redefines the issue of radioactive waste management and sets it at the centre of the current debate about power, the environment and society.

Hazardous waste incineration technologies have been developed to meet the needs of a rapidly growing market that has been created by the proliferation of hazardous waste in modern society. These hazardous wastes are continuously produced as by-products of many industries. Vast stockpiles of hazardous or toxic wastes are currently residing in insecure landfills, thus imperiling our drinking water supplies. This handbook is written with the user in mind. An in-depth review of regulatory and technical requirements is presented with later sections regarding permitting and operation of incineration facilities. A comprehensive description of established and emerging incinerator technologies is included along with a number of alternatives. One of the key sections involves a detailed procedure for choosing an incinerator for a specific job, including engineering calculations and going through the bid process. Rationale for whether to buy or lease incineration equipment is included as well as details on trial burns, permitting strategies, and startup and operation of incinerators. A number of typical case histories of incinerators are presented for such diverse applications as cleaning up individual sites with transportable units, stationary facilities for in-house wastes, and incinerator ships. Appendices provide a convenient reference to physical properties, combustion parameters, detailed equipment performance nomographs and several sample permits including RCRA, TSCA and local permit applications. In summary, this handbook provides a single reference point for the potential user of an incinerator as well as a valuable source of design data for incinerator vendors, consultants and regulators.

Sanitary landfills are the most widely utilized method of solid waste disposal around the world. With increased use and public awareness of this method of disposal, there is much concern with respect to the pollution potential of the landfill leachate. Depending on the composition and extent of decomposition of the refuse and hydrological factors, the leachate may become highly contaminated. As leachate migrates away from a landfill, it may cause serious pollution to the groundwater aquifer as well as adjacent surface waters. There is growing concern about surface and groundwater pollution from leachate. Better understanding and prediction of leachate generation, containment, and treatment are needed. This book contains a literature review of various methodologies that have been developed for prediction, generation, characterization, containment, control, and treatment of leachate from sanitary landfills. The contents of this book are divided into nine chapters. Each chapter contains theory and definition of the important design parameters, literature review, example calculations, and references. Chapter 1 is devoted to basic facts of solid waste problems current status and future trends towards waste reduction and recycling. Chapter 2 provides a general overview of municipal solid waste generation, collection, transport, resource recovery and reuse, and disposal options. The current status of sanitary landfill design and operation, problems associated with the landfilling, and future trends are presented in Chapter 3. Methods of enhanced stabilization, recycling landfill space, methane recovery, and above grade landfilling, and closure and post closure care of completed landfills are also discussed in detail. Chapter 4 provides a general overview of Subtitle D regulations and its impact upon sanitary landfilling practices. Chapter 5 is devoted entirely to moisture routing and leachate generation mechanisms.

Nuclear power issues have long been controversial, and often discussed from an inadequate or mistaken understanding. This book is a factual description of the whole fuel cycle, with individual chapters on specific topics from uranium mining, through the manufacture and use of fuel, to recycled products, waste disposal and progress towards a cleared site. Basic principles, environmental radioactivity (both natural and artificial) and provisions for safety are also covered. The level is pitched at a general scientific readership not necessarily familiar with the concepts, and although the viewpoint is naturally pro-nuclear, the aim is to inform rather than persuade. Where options are disputed, as whether used fuel should br reprocessed or discarded directly, both are described. The account is mainly of current practices, with the reasons for them. A final chapter suggests possible changes in the near or more distant future.

This title includes a number of Open Access chapters. Increasing attention is being paid to the valorization of solid wastes-converting them into energy or other useful products. This book describes recent research into methodologies and technologies for managing various forms of solid waste, while at the same time generating energy and revenue with less impact on the environment. Topics include combustion, gasification, pyrolysis, and hydrothermal carbonization. The transition from a fossil fuel-based economy to a more sustainable economy will require a solid foundation of ongoing scientific research. The editor of this compendium, a well-respected researcher in the field, has selected studies that help to build that foundation.

It also provides relevant research, recommendations, and suggestions for improving the management and oversight of PBTs.

As water demand has increased globally and resources have become more limited because of physical scarcity, over-exploitation and pollution, it has been necessary to develop more options for water supplies. These options include the production at large scale of high-quality reused water from municipal sources for potable uses. Their economic, social and environmental benefits have been many as they have addressed supply scarcity, efficient resource use and environmental and public health considerations. This book includes discussions on potable water reuse history; emerging contaminants and public health; public-private partnerships in the water reuse sector; regulatory frameworks for reused water in the United States and Europe; experiences in Australia, China in general and Beijing in particular, Singapore and Windhoek; narratives and public acceptance and perceptions of alternative water sources. The main constraints on implementation of water reuse projects in different parts of the world seem to have been lack of full public support due to perceived health hazards and environmental impacts. A main handicap has been that governments and water utilities have been slow to understand public concerns and perceptions. After several backlashes, public information, communication and awareness campaigns, broader participation and educational programmes have become integral parts of development policy and decision-making frameworks.

The third edition of a bestseller, Hazardous Materials Chemistry for Emergency Responders continues to provide the fundamentals of "street chemistry" required by emergency response personnel. Emergency response and hazmat expert Robert Burke takes the basics of chemistry appropriate for response personnel and puts it into understandable terms. The author has retained the style and format that made the previous editions so popular while updating the information to keep the book relevant. See What's in the Third Edition: Expanded section on Ethanol and its hazards to responders Update of NFPA 472 Chemistry requirements Revised section on "hazmat elements" with more hazards and response issues Includes a focus on the importance of the "hazmat elements" of chemical families New incident examples New photographs and graphics The chapters are organized by the nine U.S. Department of Transportation's hazard classes. Almost every hazardous material presents more than one hazard; the DOT's placarding and labeling system only identifies the most severe hazards. Therefore, the book provides additional information about hidden hazards for each hazard class. It discusses individual chemicals, their hazards and their physical and chemical characteristics, both as distinct chemicals and within chemical families. The book offers a concise presentation of the topics of most importance to emergency responders on a day-to-day basis. It provides the basic chemistry a responder needs to understand chemical terminology and communicate with others about the chemicals involved in hazardous materials incidents.
