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.

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.

WINNER: 2020 International Solid Waste Association Publication Award Among other factors, rapid global population growth, our development model and patterns of production and consumption have increased waste generation worldwide to unsustainable rates. This rise has led to crises in many countries where waste management practices are no longer sound. Global Waste Management outlines the emerging global waste crisis considering the perspectives of developed and developing countries around the world and the international relationships between them. This book provides an ecological viewpoint as well as studying these problems from a legal and justice standpoint. Global Waste Management contextualises the problems faced when dealing with waste including the causes and origins. Focus is given to cross border waste transfer, as an ongoing and controversial practice, making waste management a global matter. This book scrutinizes existing international, European and Brazilian regulation on waste to highlight the complexity of the subject and the weaknesses of the law. Using a critical and socio-ecological approach, the book proposes an original model of governance to support a new system of global waste management that takes into account ecological sustainability and social justice to overcome the waste crisis. To create these models, a theoretical framework on socio-ecological justice is developed and combined with different discourses and theories described throughout the book. This is the essential guide to understanding the global waste crisis and the future of waste management.

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.

Industrial wastewater contains many pollutants. This book focuses on heavy metals found in textile effluents because of their known toxicity effect in the environment. Wastewater from a textile industry (UTEXRWA) in Rwanda has been screened for the occurrence of Cd, Cr, Cu, Pb, and Zn. Batch and pilot experiments on adsorption equilibrium, kinetics, and sulfide precipitation using volcanic rock as adsorbent and packing material have been investigated. A low cost and integrated system for treatment has been developed, combining an anaerobic bioreactor as the main treatment step, followed by a polishing step composed by a polishing pond containing algae, duckweed, and water hyacinth. More than 90% of metal removal was achieved in the bioreactor, with metal sulfide precipitation as long-term removal mechanism. The use of algae and duckweed as alternatives for water hyacinth plants showed no differences between algae and duckweed ponds based on abiotic differences. Overall, both systems' performance was close and these systems are well suited as a polishing step for wastewater containing low metal concentrations. The integrated system for heavy metal removal showed how two complementary systems for heavy metal removal can work in combination and good removal performance can therefore be achieved.

Waste electrical and electronic equipment (WEEE) generation is a global problem. Despite the growing awareness and deterring legislation, most of the WEEE is disposed improperly, i.e. landfilled or otherwise shipped overseas, and treated in sub-standard conditions. Informal recycling of WEEE has catastrophic effects on humans and the environment. WEEE contains considerable quantities of valuable metals such as base metals, precious metals and rare earth elements (REE). Metal recovery from WEEE is conventionally carried out by pyrometallurgical and hydrometallurgical methods. In this PhD research, novel metal recovery technologies from WEEE are investigated. Using acidophilic and cyanide-generating bacteria, copper and gold were removed from crushed electronic waste with removal efficiencies of 98.4 and 44.0%, respectively. The leached metals in solution were recovered using sulfidic precipitation and electrowinning separation techniques. Finally, a techno-economic assessment of the technology was studied. This research addresses the knowledge gap on two metal extraction approaches, namely chemical and biological, from a secondary source of metals. The essential parameters of the selective metal recovery processes, scale-up potential, techno-economic and sustainability assessment have been studied.

Construction and Demolition Waste (CDW), from the construction, maintenance, renovation and demolition of buildings and structures, represents a large proportion of the waste in industrialized societies. Compared to other forms, such as household waste, more than 90% of CDW can be used as a resource and a substitute for construction materials, especially for primary, natural raw materials. Reuse, recovery and recycling depends on the quality and market for the materials, and the environmental impact of the processes for conversion of CDW from old structures to its use in new structures. However, the utilization today of CDW products as secondary resources is marginal. Most CDW is deposited or used as fill material, and the opportunities of high quality recycling are generally neglected. This book presents the opportunities for the sustainable and resource efficient utilisation of CDW, focusing on recycling of concrete and masonry as the major forms of CDW. The recycling of gypsum, timber, mineral wool, asphalt and other types are also described. Its aim is to present a chain of value and material streams in the transformation of obsolete buildings and structures into new buildings and structures. It takes a holistic view, focusing on the lifecycle economy (the circular economy) and integrated management aspects of various scenarios ranging from high industrial urban renewal to debris removal and management after disasters and conflicts. It is based on the authors 35 years of research and development combined with practical international experience within the demolition and recycling area. It addresses students, architects, civil engineers, building owners, public authorities and others working in urban planning, demolition and resource management in the building and construction sector and in the reconstruction of damaged buildings after disasters and wars.

Though we are the most wasteful people in the history of the world, very few of us know what becomes of our waste. In Waste Away, Joshua O. Reno reveals how North Americans have been shaped by their preferred means of disposal: sanitary landfill. Based on the author's fieldwork as a common laborer at a large, transnational landfill on the outskirts of Detroit, the book argues that waste management helps our possessions and dwellings to last by removing the transient materials they shed and sending them elsewhere. Ethnography conducted with waste workers shows how they conceal and contain other people's wastes, all while negotiating the filth of their occupation, holding on to middle-class aspirations, and occasionally scavenging worthwhile stuff from the trash. Waste Away also traces the circumstances that led one community to host two landfills and made Michigan a leading importer of foreign waste. Focusing on local activists opposed to the transnational waste trade with Canada, the book's ethnography analyzes their attempts to politicize the removal of waste out of sight that many take for granted. Documenting these different ways of relating to the management of North American rubbish, Waste Away demonstrates how the landfills we create remake us in turn, often behind our backs and beneath our notice.
