The book guides specialists and non-specialists from around the world on how or whether anaerobic processes can be part of solutions for the management of municipal and industrial solid, semi-solid, and liquid residues. The simple self-learning presentation style is designed to encourage deep understanding of the process principles, plant types and system configurations, performance capabilities, operational and maintenance requirements, post-treatment needs, and management options for coproducts without complex biochemical terminologies and equations. It describes key aerobic biological treatment processes used in conjunction with anaerobic biological treatment in feedstock pre-treatment and in post-treatment of by-products. Practical pre-treatment processes, techniques and operations are described alongside additional treatment techniques of biogas, digestates and treated effluents for various end use options. Effective applications in developing countries are also considered, enabling practitioners and plant operators to effectively apply technology in temperate and warm climatic conditions.
This book states the harsh truth: that despite best intentions, our current environmental practices are doing more harm than good, and that the solution lies in creating supply chains of the future that design, produce, consume, and reuse materials in a manner that is balanced economically and environmentally. One billion beverage containers are used on a daily basis in the United States, with at least 600 million of them ending up in landfills. Even the 400 million that are recycled-at a great cost-are not accomplishing the task of helping the environment. This economic and environmental catastrophe cannot be solved by recycling programs. From his experience as a leader in the American consumer beverage industry and a researcher in Sweden, author Jack Buffington has developed a transformational solution that seeks to not just mitigate the environmental damage but jumpstart the economy while actually achieving zero waste. The Recycling Myth tells the story of how our current environmental practices are unintentionally doing more harm than good and how we need to create a radically different supply chain of the future that must, as best as possible, copy the natural system of growth, decay, and regrowth, and discontinue a disastrous pattern of material design and use. Backed by irrefutable evidence, the book destroys our comfortable notions of the recycling status quo; explains why recycling will never work in the United States, despite decades of attempts; and introduces a new system that will actually work-without asking consumers to consume less. Supplies an informed perspective from a leader in the consumer beverage industry at one of the world's largest producers of packaged beverages and a researcher in Sweden in the fields of environmental science and supply chain logistics Presents a bold counterargument to the idea that recycling and sustainability programs are inherently beneficial and introduces a new system that will benefit both our environment and economy-without asking consumers to consume less Explains why recycling and sustainability programs are ineffective because they focus solely on doing less harm rather than improving both the economy and the environment
During 1978-1982 the International Institute for Applied Systems Analysis (IIASA) was responsible for a research project on Environmental Quality Control and Management. The project was begun under the direction of Professor O. F. Vasiliev (from the Institute of Hydrodynamics of the Siberian Branch of the USSR Academy of Sciences) and was subsequently led by myself. This review is very much a re'fiection of that IIASA project. The major themes of the IIASA project were: (i) research into the methodological aspects of modeling river and lake sys tems [some of the principal results of this research appear in M. B. Beck and G. van Straten (eds. ) (1983), Uncertainty and Forecasting of Water Quality (Springer, Berlin (West)), and in K. Fedra (1983), Environmental Modeling Under Uncertainty: Monte Carlo Simulation (IIASA Research Report RR-83-28)]; (ii) case studies in the application of mathematical models to lake eutrophi cation control [results of which are summarized in L. Somlyody, S. Hero dek, and J. Fischer (eds. ) (1983), Eutrophication of Shallow Lakes: Model ing and Management (The Lake Balaton Case Study) (IIASA Collaborative Proceedings CP-83-S3), and in K. Fedra (1983), A Modular Approach to Comprehensive System Simulation: A Case Study of Lakes and Watersheds (in W. K. Lauenroth, G. V. Skogerboe, and M. Flug (eds. ), Analysis of Ecological Systems: State-of-the-Art in Ecological Modelling, pp. 195-204. Elsevier, Amsterdam)]; iv (iii) a policy study of operational water qua,lity management [M. B. Beck (1981), Operational Water Quality Management: Beyond Planning and Design (IIASA Executive Report ER-7)].
The use of catalytic converters for the purification of automotive exhaust gases is a relatively new technology which was brought into existence by social pressures for the preservation of acceptable environmental conditions. The majority of catalytic practitioners have been able to watch the growth of this technology from its inception to its current state of sophistication.

Transportation Tunnels, 2nd Edition provides a comprehensive text on tunneling and tunnel engineering applicable in general to all types of tunnels, with more detailed information on highway and railway tunnels. While the First Edition of the book was confined to deal with railway and highway tunnels, the Second Edition is also extensively considering the latest trends in use of tunnels in different other fields. The book has been revised to provide coverage of water conveyance, navigation and material conveyance tunnels also and deals with these subjects in more detail. It covers all aspects of investigation, design, construction, monitoring and maintenance of tunnels. Special emphasis has been laid on the geotechnical investigations, interpretation of findings and relating the same to the design as well as the construction of tunnels. The book reflects the advancements in the knowledge of ground behaviour and rock mechanics and also in construction technology, including use of TBM in the last two decades. It covers in sufficient detail the basic requirements of tunnel profile, the geometric parameters, clearance requirements, aerodynamics, and cost economics in fixing alignments with different design parameters like curvature, gradient and operational requirements. It discusses in detail alternative forms of the cross section / profile and illustrates design methodology with examples. The different methodologies that have been used in the past using timber or steel supports by stage wise expansion of cross sections and modern methodologies used for boring full profile using new tunneling methods and Tunnel Boring Machines are also comprehensively discussed. Requirements of tunnels in respect of ventilation, lighting and drainage are adequately covered. Separate chapters have been included on 'Instrumentation' and 'Tunnel Inspection and Maintenance'. The expanded text on the use and advantages of methodologies and equipment for dealing with various aspects of construction of tunnels is based on observations through site visits, discussions with, and experiences of people as recorded on large number of tunneling works which have been taken up recently for railways, highways and urban transport subway projects. The book can serve as a textbook for undergraduate and graduate students and as a reference book for practicing engineers.
Constructed Wetlands (CWs) are among the few natural treatment systems that can guarantee an efficient wastewater treatment and an appealing green space at the same time. However, they require large areas for their construction, which is not available in many cases. In this thesis, two domestic wastewater treatment options were designed and studied with the purpose of having a low space requirement: the Duplex-CW and the Constructed Wetoof (CWR). The Duplex-CW is a hybrid CW composed of a vertical flow CW on top of a horizontal flow filter. The stacked arrangement is the key for reducing the CW footprint. The CWR is a shallow HF CW placed on the roof of a building, thus it does not occupy any land. Several modifications and improvements have been tested, in addition to the study of the treatment performance, in order to select the most appropriate Duplex-CW and CWR design. Overall, this thesis contributes to the development of two efficient domestic wastewater treatment technologies. The Duplex-CW area requirement is still higher than many CWs and therefore further improvements are necessary. The CWR is the foremost option to save land areas since it requires 0 m2 of land per person equivalent.
The enormous public interest of specialists as well as of engaged and concerned citizens in the energy problem can be understood in view of the fact that the future of national and world-wide economy depends on the availability of sufficient primary energy. The questions arising are: which forms of primary energy exist principally? by what means and at what cost can they be brought to useful application? and what is their possible role in the present and future energy scenario? Another reason which may not be so obvious, but which eventually may prove to be of great importance as far as public acceptance of energy technologies is con cerned, lies in the fact that the existing conscious or subconscious fears arising from confrontation with scientific and technological progress - to which even for the educated layman intellectual access is diffi cult - have been sublimated onto the energy problem and especially onto the problem of nuclear energy. Un like other developments, the emergence of nuclear ener gy has brought to our notice the ambivalence of ad vancing science and technology, which may either be used peacefully or misused militarily. Nuclear energy can help to overcome the increasing hunger for energy in the world, but it can also lead to the extinction of human life from the surface of this plant. More and more, mankind is confronted with chances and risks of new discoveries.

As society becomes stressed by economic and population pressures, in turn, nature's renewable resources become stressed by harvesting pressures. For our own survival and euphoria, it is paramount that such resources remain as their name implies and not be driven to extinction through short term programs of over exploitation. Consideration of the harvesting of renewable resources leads to a simple question that was the theme of the workshop and is the focus of these proceedings: SUPPoRe you are assigned the role of manager for a specific renewable resource eco system. How would you decide on harvesting policies so that the system can be exploited economically yet at the same time maintain the integrity of the system? This, of course, is a loaded question. First of all, it is not clear that there is ever anyone single decision maker who is able to set the rules for all of the harvesters in an exploited ecosystem. The political process is complicated and to some extent unpredictable. This aspect of the question is recognized to be important, but could not be addressed here. Assuming then that someone really is in charge, what would be involved in the * decision making process? As Clark points out, "there is no alternative but first to model the system. " We agree. However, if the original question was loaded, modeling is the adulterate."
Zsuzsa Gille combines social history, cultural analysis, and environmental sociology to advance a long overdue social theory of waste in this study of waste management, Hungarian state socialism, and post Cold War capitalism. From 1948 to the end of the Soviet period, Hungary developed a cult of waste that valued reuse and recycling. With privatization the old environmentally beneficial, though not flawless, waste regime was eliminated, and dumping and waste incineration were again promoted. Gille s analysis focuses on the struggle between a Budapest-based chemical company and the small rural village that became its toxic dump site."
A major problem confronting the United States in the 21st century is the 20th centurys legacy of toxic waste. The weapons that fought the Cold War, the facilities that manufactured those weapons, and the factories that fueled a prosperous economy left behind a trail of pollution. Seven previously unpublished essays examine the problem of toxic waste in the United States, what is being done about it, and what should be done about it. W. Henry Lambright and Agnes Gereben Schaefer, Dianne Rahm, Sevim Ahmedov, Charles Davis, Robert A. Simons and Kimberly Winson, Santa Falcone, and Toddi A. Steelman and JoAnn Carmin write about such issues as community based environmental management, regional EPA offices and the regulation of hazardous wastes, "brownfields, " nuclear and chemical weapons destruction, environmental contamination and the nuclear weapons complex, the privatization of nuclear waste clean-up, and WIPP, Yucca, and hazardous waste transport. The future of humanity demands careful thought about these matters.
Current development results in a linear flow from raw material to waste, which cannot be sustainable in the long term. Plus, a global population of 7 billion people means that there are 7 billion waste producers in the world. At present, dumping and landfilling are the primary practices for getting rid of municipal solid waste (MSW). However, this waste contains resources that we've yet to utilize. To create sustainable societies, we need to approach zero waste by recovering these resources. There are cities and countries where zero waste is close to becoming a reality. Landfilling of organic waste is forbidden in Europe, and countries such as Sweden, Germany, Belgium, and Switzerland have developed a variety of technologies to recover resources from MSW. Resource Recovery to Approach Zero Municipal Waste explores the solid waste management laws and regulations of different countries, comparing the latest resource recovery technologies and offering future perspectives. The book tackles the many technical, social, ecological, economical, and managerial aspects of this complex subject while promoting the development of sustainable societies to achieve a greener global environment.

Metallurgical slags are generated as a by-product of smelting during ironmaking, steelmaking, and the production of ferroalloys and non-ferrous metals. The formation conditions result in complex chemical and mineralogical characteristics unique to slags alone. Historically slags have been discarded as a waste product and, through release of potentially toxic trace elements, represent a hazard to the environment and human health. However, increasingly we are realizing the resource potential of what was previously thought of as waste, thus reducing the environmental impact and taking a step closer to a circular economy. This book is a definitive reference on the environmental geochemistry and resource potential of metallurgical slags by summarizing processes for the generation of slags, describing their chemical and mineralogical characteristics, outlining the fundamental geochemistry that propels slag weathering, and illustrating the utilization of slags. Particular attention is given to the value of slags in modern society as they are widely used as construction materials in civil engineering, and as an irreplaceable filter in sequestering excess nutrients, pathogens, metal and/or organic contaminants, and even greenhouse gases. The latest developments on recovering residual valuable metals in slags, including new techniques for extracting by-product elements needed for green and frontier technologies, are revealed. This book is essential reading for environmental geochemists, geologists, metallurgists, mining and civil engineers, waste and resource managers, and all those interested and inspired by a circular economy and minimizing our environmental footprint on planet Earth.
As prosperity levels rise, so too does the level of products and services manufactured. For decision makers facing a growing waste burden, it is imperative that more sustainable waste management programmes are based on an understanding of the complex relationship between waste prevention policies and individual behavior regarding waste generation. This book examines the interplay; taking a close look at the role of motivation, difficulties, values and constraints. The first part of the book explores the theoretical framework, policy, barriers and facilitators for waste prevention behaviour. The second part presents in-depth case studies from three cities (in Brazil, the UK and Japan) examining the contextual factors, behavioural variations among them and the role of motivation and constraints in their populations. The book provides a detailed picture of how waste prevention policies enter the private, domestic sphere, offering insights for generating behavioural change at the household level and thus moving larger communities towards sustainable waste management.The book should be of interest to students and researchers in the areas of environmental policy, management, sociology, psychology, geography, technology and waste studies.
Edited by Reinhard Kirsch, this book demonstrates the use of geophysics for the detection and delineation of groundwater resources. As well as being an excellent reference, it could also be used as a textbook. An addition to the bookshelf of any geophysicist.
Rock Mechanics and Rock Engineering is concerned with the application of the principles of mechanics to physical, chemical and electro-magnetic processes in the upper-most layers of the earth and the design and construction of the rock structures associated with civil engineering and exploitation or extraction of natural resources in mining and petroleum engineering. Rock mechanics requires profound knowledge of rock-constituting elements, discontinuities and their behavior under various physical and chemical actions in nature. The governing equations together with constitutive laws and experimental techniques and the solution techniques are explained and some examples of applications are given. The applications of rock mechanics to engineering structures in/on rock, rock excavation techniques and in-situ monitoring techniques are explained and some specific examples are given. The dynamic aspects associated with the science of earthquakes and their effect on rock structures, and the characteristics of vibrations induced by machinery, blasting and impacts as well as measuring techniques are described. Furthermore, the degradation and maintenance processes in rock engineering are explained. Some chapters are devoted to possible new directions in rock mechanics. This two-volume set is intended to be a fundamental resource for younger generations and newcomers and a reference work for experts specialized in Rock Mechanics and Rock Engineering and associated with the fields of mining, civil and petroleum engineering, engineering geology, and/or specialized in Geophysics and concerned with earthquake science and engineering.
Geotextile encapsulated sand elements are three-dimensional systems manufactured from textile materials, non-woven materials or combinations of textile and non-woven materials that are filled with sand on-site. These systems are relatively new and the number of applications is growing in river and coastal engineering. Quite often Geosystems are mentioned as a possible solution, but planners, designers and contractors feel rather hesitant about the application of geotextile encapsulated sand elements due to a lack of experience and adequate design rules. The use of geosystems has the advantage that local material can be applied and that no (expensive) quarry stone needs to be extracted and transported from the mountains to the site. Compared to traditional construction methods (with quarry stone) the application of geotextile sand filled elements may add considerable operational advantages to the execution of marine works and may offer attractive financial opportunities. In the application of geotextile encapsulated sand elements however, proper attention should be paid to the laying down of different responsibilities of the parties in the contract. In Geosystems. Design Rules and Applications four types of geotextile sand elements are distinguished, each with specific properties: geo-bags, geo-mattresses, geotextile tubes and geotextile containers. The focus is on the use of geosystems filled with sand as a construction in river and coastal engineering. Geosystems filled with sludge are not covered. The chapters "Introduction" and "General design aspects" are followed by four chapters of the same structure dealing with the various systems. Each of these four chapters starts with a general description and applications and ends with a calculation example. Design aspects are dealt with in the remaining paragraphs. Geosystems. Design Rules and Applications is based on research commissioned by the Dutch Rijkswa
Conflicts over waste disposal facility siting is a pressing issue not only in developed countries but also in fast-growing countries that face drastic waste increase and rapid urbanisation. How to address distributive justice has been one of the biggest concerns. This book examines what determines the influence of distributive justice in siting policy. In the 23 wards of Tokyo, one idea of distributive justice, known as "In-Ward Waste Disposal" (IWWD), emerged amid the ongoing garbage crisis in the early 1970s. IWWD was adopted as a significant principle, but its influence waxed and waned over time, until the idea was finally abandoned in 2003. To unravel causes and mechanisms behind the changing influence of IWWD, this book adopts a framework that considers not only ideational causes, but also the power struggles between rationally calculating actors, as well as the influence of external events and environments. By combining an in-depth case study with an integrative theoretical framework, this book tells a thought-provoking story of the changing influence of IWWD in a deep, comprehensive and consistent way. This book provides significant insights and lessons for both academics and practitioners.
This book compiles research findings directly related to sustainable and economic waste management and resource recovery. Mining wastes and municipal, urban, domestic, industrial and agricultural wastes and effluents-which contain persistent organic contaminants, nanoparticle organic chemicals, nutrients, energy, organic materials, heavy metal, rare earth elements, iron, steel, bauxite, coal and other valuable materials-are significantly responsible for environmental contamination. These low-tenor raw materials, if recycled, can significantly address the demand-supply chain mismatch and process sustainability as a whole while simultaneously decreasing their impacts on human life and biodiversity. This book summarises the large volume of current research in the realm of waste management and resource recovery, which has led to innovation and commercialisation of sustainable and economic waste management for improved environmental safety and improved economics. Key Features: Reviews the key research findings related to sustainable and economic resource recovery and waste management techniques Discusses minimizing waste materials and environmental contaminants with a focus on recovering valuable resources from wastes Examines the potential uses of mining waste in the re-extraction of metals, provision of fuel for power plants, and as a supply of other valuable materials for utilisation/processing Presents research on recycling of municipal, urban, domestic, industrial and agricultural wastes and wastewater in the production and recovery of energy, biogas, fertilizers, organic materials and nutrients Outlines topical research interests resulting in patents and inventions for sustainable and economic waste management techniques and environmental safety
This book provides extensive information on the chemicals that inhabit our environment, our food, our water and our air and the impact that they may be having on human health. The author is a medical scientist, with training in the law. The book documents current understanding about pesticides in food, the plastics revolution, toxic metals, air, water and electronic waste pollutants, chemical exposure in the workplace, radiation pollutants, chemical exposure and hearing loss, how our bodies deal with chemicals, genetic variability and the risk of disease, the effect of chemicals on genes, mitochondria and the immune system and what we can do about it all. Industrialisation has resulted in many thousands of chemicals, which are being continuously developed and often escaping from where they are used into our human environment, without us really knowing enough about them. In high dosages or with continuous small dosage, the evidence suggests, that many of them could interfere with human health and some of them are known to be doing so. But for the vast majority, we are left wondering whether some could be responsible for some diseases the causes of which are inadequately understood. Every chapter is thoroughly reinforced with several pages of references from the peer-reviewed literature.
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. |
