This book focuses on biogas production by anaerobic digestion, which is the most popular bioenergy technology of today. Using anaerobic digestion for the production of biogas is a sustainable approach that simultaneously also allows the treatment of organic waste. The energy contained in the substrate is released in the form of biogas, which can be employed as a renewable fuel in diverse industrial sectors. Although biogas generation is considered an established process, it continues to evolve, e.g. by incorporating modifications and improvements to increase its efficiency and its downstream applications. The chapters of this book review the progress made related to feedstock, system configuration and operational conditions. It also addresses microbial pathways utilized, as well as storage, transportation and usage of biogas. This book is an up-to-date resource for scientists and students working on improving biogas production.
Beyond Recycling critically explores unasked questions around recycling and its prominent position in contemporary thinking about sustainability. It examines and challenges assumptions about why we appear to have so wholeheartedly committed to recycling as a cultural project. Recycling has become a commonplace notion and widespread practice. Yet its social, cultural and even environmental value has not been considered carefully enough. This book considers recycling as a contemporary cultural idea related to - but not wholly defined by - our response to material waste. It seeks to reclaim recycling from the environmentalists and waste management specialists, to explore the role it plays in wider contemporary discourse. As we become increasingly satiated, and in many cases sickened, by the excesses of modern consumerism, we are rethinking our relationship with the physical stuff that fills our lives. Dissatisfied with empty materialism, we seek new ways to reuse our material culture. Recycling, turning something considered to be waste into something with renewed value, is our primary collective response to the problems arising from consumption; and it is ripe for critical examination. Beyond Recycling is a fascinating read for conscious consumers and students in the creative arts, design, cultural studies, sustainability and environmental studies.
In the past 13 years since the publication of Longwall Mining, 2nd edition in 2006, although there have been no major changes in longwall mining technology and operations, many incremental developments in the whole system as well as various subsystems of the existing longwall mining operational technologies as detailed in the 2nd edition have been added to this edition. Major developments are automation, and health and safety technology, as well as equipment reliability, thereby greatly increasing productivity and cutting cost. In particular, the longwall system can now run automatically cut by cut forever without operators' intervention provided that the geology allows it. Other health and safety features such as LASC, personal proximity detection, color lighting, automatic shield water sprays and remote shearer control are fully operational. There are more than 7000 sensors installed in current longwall mining systems. The big data obtained and fast communication technology have been fully utilized to improve and solve operational problems in real time. Those features are fully documented in the new edition. In pursuit of high productivity and cutting cost, life cycle management that increases equipment reliability has been implemented by OEM. Automation improvement such as tail-end automatic chain tensioner greatly extends AFC chain's service life. Other incremental improvements including dust and methane controls, entry development, panel design and face move are addressed. Additional operational issues such as extension of panel width and compatibility test are also discussed. Since the last plow longwall mine was closed in 2018, the chapter on plow longwalling has been dropped and in its place Automation of Longwall Components and System is added. Also, a new chapter Longwall Top Coal Caving Mining (LTCC) is added due to its successful application in Australia since 2005. Longwall Mining, 3rd edition will be of interest to professionals and academics in the field of mining engineering specifically, serving both as a reference work and an (under)graduate textbook, but will also interest civil, geomechanical and geological engineers and rock mechanics professionals, as well as coal operators, mining consultants, researchers, equipment manufacturers, and government regulators.
Despite frequent claims that waste is being reduced, consumer-reliant economies, everyday consumption and the waste industry continue to produce and demand more waste. Combining a lucid style with robust empirical and theoretical research, this book examines the root causes of the global waste problem, rather than simply the symptoms. It challenges existing waste policies, highlighting what needs to change if we are to get serious in tackling this global problem. It concludes with policy implications for shifting waste from an 'end-of-pipe' concern to being at the heart of the debate over decarbonisation.
This book chiefly focuses on environmental flow, water pollution and water quality. Several chapters also cover water treatment technologies and management. In today's context, climate change and climate variability are important issues in the water sector, which is called upon to develop adaptation strategies to cope with their negative impacts. Human health depends upon the quality of water used for drinking and irrigation purposes. These core issues are discussed and addressed in several chapters. The book explores the impact of climate change on water resources and considers various climatological scenarios. In this regard, it carries out a trend analysis and compares the performance of various Global Climate Models (GCMs). Further, it conducts a water quality analysis and water quality mapping so as to provide information on the most vulnerable areas in the context of water quality. Emerging pollutants, generated from paper mills, are identified in order to choose an appropriate treatment technology. Bioremediation techniques are included for the characterization of improved water quality parameters. The book also presents a low-cost treatment technology for fluoride removal, which can help water managers ensure potable water to stakeholders. In terms of maintaining river ecology in the downstream areas of water resources project sites, the book provides a number of case studies on assessment of environmental flows. Advanced treatment technologies that can be highly advantageous for removing water pollutants are presented. Given its scope, the book offers a valuable resource for academics, water resources practitioners, scientists, water managers, environmentalists, administrators, NGOs, researchers and students who are involved in water management with a main focus on water pollution, the environment, climate change and health.
Acid mine drainage (AMD) is essentially the flow of water polluted with metals and other substances from existing/old mining areas and is considered to be one of the sources of pollution. A wide range of technologies are available for preventing AMD generation and/or treating AMD before discharge, but there is a shift towards recovery of industrially useful materials and products from AMD.

The threat from global warming is growing and human activity is a major contributor to the problem. It is clear that we must change our wasteful behavior before it is too late. The Tzu Chi Foundation believes it can make a difference in addressing this critically important challenge. Over the last three decades it has embraced the cause of recycling and conserving resources to ensure a cleaner environment for future generations. Tzu Chi has mobilized tens of thousands of people in this campaign, expanding from Taiwan to 19 countries and territories around the world. Co-Existing with the Earth, Tzu Chi's Three Decades of Recycling tells the story of this uniquely effective grassroots effort and examines the reasons for its success. It also relates the stories of individual recycling volunteers and explains why they chose to join this international movement.
This Practical Guide to Rock Tunneling fills an important void in the literature for a practical guide to the design and construction of tunnels in rock. Practical Guide to Rock Tunneling takes the reader through all the critical steps of the design and construction for rock tunnels starting from geotechnical site investigations through to construction supervision. The guide provides suggestions and recommendations for practitioners on special topics of laboratory testing, durability of rock and acceptance for unlined water conveyance tunnels, overstressing or deep and long tunnels, risk-based evaluation of excavation methods, contract strategies, and post-construction inspections. Key considerations and lessons learned from selected case projects are presented based on the author's extensive international experience of over 30 years and 1000 km of tunneling for civil, hydropower, and mining infrastructure, including some of the most recognized projects in the world to date. Instead of revisiting all theory and concepts that can be found in other sources, this book contains the hard learned lessons from the author's experience in the field of Rock Tunneling, gathered over 30 years of service.
This book discusses in detail the concepts of recycling and upcycling and their implications for the textiles and fashion sector. In addition to the theoretical concepts, the book also presents various options for recycling and upcycling in textiles and fashion. Although recycling is a much-developed and widely used concept, upcycling is also gaining popularity in the sector.
Rubbish. Waste. Trash. Whatever term you choose to describe the things we throw away, the connotations are the same; of something dirty, useless and incontrovertibly 'bad'. But does such a dismissive rendering mask a more nuanced reality? In Rubbish Belongs to the Poor, Patrick O'Hare journeys to the heart of Uruguay's waste disposal system in order to reconceptualize rubbish as a 21st century commons, at risk of enclosure. On a giant landfill site outside the capital Montevideo we meet the book's central protagonists, the 'classifiers': waste-pickers who recover and recycle materials in and around its fenced but porous perimeter. Here the struggle of classifiers against the enclosure of the landfill, justified on the grounds of hygiene, is brought into dialogue with other historical and contemporary enclosures - from urban privatizations to rural evictions - to shed light on the nature of contemporary forms of capitalist dispossession. Supplementing this rich ethnography with the author's own insights from dumpster diving in the UK, the book analyses capitalism's relations with its material surpluses and what these tell us about its expansionary logics, limits and liminal spaces. Rubbish Belongs to the Poor ultimately proposes a fundamental rethinking of the links between waste, capitalism and dignified work.

This collection breaks new ground by investigating applications of degrowth in a range of geographic, practical and theoretical contexts along the food chain. Degrowth challenges growth and advocates for everyday practices that limit socio-metabolic energy and material flows within planetary constraints. As such, the editors intend to map possibilities for food for degrowth to become established as a field of study. International contributors offer a range of examples and possibilities to develop more sustainable, localised, resilient and healthy food systems using degrowth principles of sufficiency, frugal abundance, security, autonomy and conviviality. Chapters are clustered in parts that critically examine food for degrowth in spheres of the household, collectives, networks, and narratives of broader activism and discourses. Themes include broadening and deepening concepts of care in food provisioning and social contexts; critically applying appropriate technologies; appreciating and integrating indigenous perspectives; challenging notions of 'waste', 'circular economies' and commodification; and addressing the ever-present impacts of market logic framed by growth. This book will be of greatest interest to students and scholars of critical food studies, sustainability studies, urban political ecology, geography, environmental studies such as environmental sociology, anthropology, ethnography, ecological economics and urban design and planning.
This book investigates the complex and unpredictable temporalities of waste. Reflecting on waste in the context of sustainability, materiality, social practices, subjectivity and environmental challenges, the book covers a wide range of settings, from the municipal garbage crisis in Beirut, to food rescue campaigns in Hong Kong and the toxic by-products of computer chip production in Silicon Valley. Waste is one of the most pressing issues of the day, central to environmental challenges and the development of healthier and more sustainable futures. The emergence of the new field of discard studies, in addition to expanding research across other disciplines within the social sciences, is testament to the centrality of waste as a crucial social, material and cultural problem and to the need for multi- and transdisciplinary approaches like those provided in this volume. This edited collection seeks to develop a framework that understands the material properties of different kinds of waste, not as fixed, stable or singular but asdynamic, relational and often invisible. It brings together new and cutting-edge research on the temporalities of waste by a diverse range of international authors. Collectively, this research presents a persuasive argument about the need to give more credence to the capacities of waste to provoke us in materially and temporally complex ways, especially those substances that complicate our understandings of life as bounded duration. This book will be of great interest to students and scholars of the environmental humanities, cultural studies, anthropology and human geography.

The Observational Method (OM) is a natural and powerful technique that maximises economy while assuring safety. Its key features are highlighted in The Observational Method in Civil Engineering through twelve case histories from major infrastructure projects. They cover protection of adjacent structures including buildings and railway systems, bored and jacked tunnels, shafts and cofferdams, retaining walls, embankments, deep foundations, ground improvement and groundwater control. They illustrate how the OM can achieve more effective collaboration between the client and the design and construction teams, as well as how it can enhance the industry's ability to learn from experience, thus improving future practice and stimulating innovation. Despite these advantages, the OM is significantly underused. The book demonstrates how the full potential of the OM can overcome a wide range of concerns and constraints. Other chapters address the advantages and limitations of the OM, the key role of progressive modification, the art of achieving agreement and the commercial and contractual environment. The book will appeal to a range of construction professionals, including civil, structural and geotechnical engineers, contractors and owners. It will also be of interest to students and researchers.

The book begins with a description of the biological transformations of inorganic and organic compounds and a review of strategies that may be used for the treatment of hazardous wastes. It continues with a discussion of the physiological and engineering factors that must be considered for successful process development and concludes with a discussion of the regulations that have influenced biological waste treatment and environmental remediation.
First published in 1997, this volume examines the urban environments of Accra (Ghana), Harare (Zimbabwe) and Gaborone (Botswana). Each was effectively the capital city of a former British colony, and hence inherited a concern for public health. Each has made a serious and largely successful effort to provide the public goods necessary for the well-being of their urban population. Each is well above the average for all of Sub-Saharan Africa (SSA) in these respects. However, the GDP per capita varies significantly between these three countries. Differences in standard of living are similarly evident. The authors focus intensively on public policies that determine who gets what, how they get it, and what price they pay.
