This book focuses on an important technology for mineralizing and utilizing CO2 instead of releasing it into the atmosphere. CO2 mineralization and utilization demonstrated in the waste-to-resource supply chain can "reduce carbon dependency, promote resource and energy efficiency, and lessen environmental quality degradation," thereby reducing environmental risks and increasing economic benefits towards Sustainable Development Goals (SDG). In this book, comprehensive information on CO2 mineralization and utilization via accelerated carbonation technology from theoretical and practical considerations was presented in 20 Chapters. It first introduces the concept of the carbon cycle from the thermodynamic point of view and then discusses principles and applications regarding environmental impact assessment of carbon capture, storage and utilization technologies. After that, it describes the theoretical and practical considerations for "Accelerated Carbonation (Mineralization)" including analytical methods, and systematically presents the carbonation mechanism and modeling (process chemistry, reaction kinetics and mass transfer) and system analysis (design and analysis of experiments, life cycle assessment and cost benefit analysis). It then provides physico-chemical properties of different types of feedstock for CO2 mineralization and then explores the valorization of carbonated products as green materials. Lastly, an integral approach for waste treatment and resource recovery is introduced, and the carbonation system is critically assessed and optimized based on engineering, environmental, and economic (3E) analysis. The book is a valuable resource for readers who take scientific and practical interests in the current and future Accelerated Carbonation Technology for CO2 Mineralization and Utilization.

How do those pushed to the margins survive in contemporary cities? What role do they play in today's increasingly complex urban ecosystems? Faced with stark disparities in human and environmental wellbeing, what form might more equitable cities take? Waste Matters argues that contemporary literature and film offer an insightful and timely response to these questions through their formal and thematic revaluation of urban waste. In their creation of a new urban imaginary which centres on discarded things, degraded places and devalued people, authors and artists such as Patrick Chamoiseau, Chris Abani, Dinaw Mengestu, Suketu Mehta and Vik Muniz suggest opportunities for an inclusive urban politics that demands systematic analysis. Waste Matters assesses the utopian promise and pragmatic limitations of their as yet under-examined work in light of today's pressing urban challenges. This book will be of great interest to scholars and students of English Literature, Postcolonial Studies, Urban Studies, Environmental Humanities and Film Studies.

Water, energy, and food are basic requirements for life, and this book presents solutions for obtaining these from sewage wastewater treatment plants. It describes the optimal recovery of value-added products from municipal sewage plants in developing countries, and explains how the plants' operations can become both economical and sustainable. Further, it shows how the clean effluent that is obtained is then suitable for agricultural use in the production of bio-fertilizers, and graywater for irrigation, and how the recovered biogas could be used for energy and heating needs. Practical case studies from three separate sewage plants are presented to illustrate the processes involved.

Discover the key facts about waste and how we can produce less to help protect our planet.

Waste management is an issue humans have encountered throughout history. We can learn a lot about the past by looking at rubbish that was buried in early rubbish dumps, called middens. This book covers the different types of garbage, how it is dealt with, and the problems that occur because of rubbish.

This is a timely entry into the award-winning DKfindout! series. It highlights some of the key global concerns, such as space waste, the problem of plastic, growing landfills, and fast fashion. It also looks at what is being done worldwide to help manage waste better, from renewable energy to eco homes.

Positive suggestions are made for trying eco-friendly swaps for single-use plastic items, wasting less food, and converting trash into treasure. This book is thought-provoking as it gets the reader to ask themselves if they really need to purchase an item and if they do buy something, to consider where it will end up after it's been used. A key way to prevent creating trash is to avoid consuming so much.

This work presents the findings of an extensive study on the state-of-the-art regarding the problem of food waste in Belarus, Estonia, Germany, Latvia, Lithuania, Poland and Sweden. The results show that the problem of food waste can be found at different levels in each country and that our knowledge of it is limited by the current lack of studies in the area. The problem is primarily due to food waste generated by the manufacturing sector, mostly in the form of unused or inefficiently used by-products, as well as on a share of food thrown away by households that is still suitable for human consumption. The main reduction/prevention method, applied across the countries, is food donation; the remaining methods are the same ones used for biodegradable waste in the respective countries. The findings gathered in this study show a number of potential measures/methods for sustainable food waste management, which may be considered in future works in order to reduce the amounts of food waste generated in each of the aforementioned countries.

This book documents the various impacts of urbanization on hydrological systems and water resources. The first half of the book is focused on urbanization and surface waters, starting with the status of hydrological systems in the urban areas, i.e. the catchment characteristics and changes in rainfall dynamics. The most pronounced hydrological problems in cities are changes in runoff due to precipitation. Recently, rain events have been less frequent but more intense, sometimes leading to flash floods. Though the substantial increase in runoff causes floods in the urbanized area, it may be attributed to the reduction of infiltration due to construction of roads. This, in turn, results in groundwater decline and depletion. The second half of the book covers the impact of urbanization on groundwater, which starts with hindered or significantly reduced recharge taking place due to altered urban surfaces. The limited groundwater resources are over-exploited by the urban population, leading to water scarcity and depletion. Groundwater gets polluted due to solid waste dumping sites or by wastewaters discharged by industries. The book will be useful for researchers, educators, municipal/city authorities, government officials, and NGOs.

The book revisit in depth scope of agroindustrial waste for enhancement in biofuels production on practical ground. It explores and discusses various cellulose rich agro-wastes along with low cost, advance technology based options for sustainable biofuels production. Lignocellulosic biomasses are potential producer of biofuels due to renewable nature and huge occurrence. Cellulose is the main polymeric component of these biomasses apart from lignin and hemicellulose. It can be converted into fermentable sugars using cellulase enzyme which can be further converted into the renewable energy sources such as biohydrogen, bioethanol, biogas and butanol. Chapters in this title provide exclusive and critical analysis of specific biofuels production process only from lignocellulosic biomass, based on their type, property, availability, cost and most important sugar or cellulose content along with the simplest process search for converting these biomasses into biofuels to make overall process more simple and economical.It is a useful guide for academician and environmentalist who are working to explore feasible advantages associated with these kinds of waste management and their effective valorization. It is also a great resource for senior undergraduate and graduate students, researchers, professionals, and other interested individuals/groups working in the field of biofuel/bioenergy.

Cementitious materials are being widely used as solidification/stabilisation and barrier materials for a variety of chemical and radioactive wastes, primarily due to their favourable retention properties for metals, radionuclides and other contaminants. The retention properties result from various mineral phases in hydrated cement that possess a high density and diversity of reactive sites for the fixation of contaminants through a variety of sorption and incorporation reactions. This book presents a state of the art review and critical evaluation of the type and magnitude of the various sorption and incorporation processes in hydrated cement systems for twenty-five elements relevant for a broad range of radioactive and industrial wastes. Effects of cement evolution or ageing on sorption/incorporation processes are explicitly evaluated and quantified. While the immobilisation of contaminants by mixing-in during hydration is not explicitly addressed, the underlying chemical processes are similar. A quantitative database on the solid/liquid distribution behaviour of radionuclides and other elements in hydrated cement systems is established on the basis of a consistent review and re-evaluation of literature data. In addition to recommended values, all underlying original experimental data and key experimental info rmation are provided, which allows users to trace the given recommendations or to develop their own set of key values. This database is closely tied to the safety analysis of near surface disposal of radioactive waste in Belgium. It focuses on radioelements, toxic stable elements and heavy metals, which makes it relevant for investigations involving the interaction of radioactive and conventional contaminants with cement-based barriers.

Natural saline water, waste water, and irrigation return flow endanger the groundwater aquifers in the Rift. In the long run this will ruin the socio-economic backbone of the settlements in the area. Sustainability of the water resources will only be achieved when the process of water replenishment and its underground flow is understood and water extraction is regionally controlled. Rare earth element and spider patterns are presented as new tools for studying the hydrology. Progress in 3-D modelling of groundwater flow proved successfully the impact of pumping on the surroundings of wells and overexploitation of aquifers.

As prosperity levels rise, so too does the number of products and services being consumed. For policy makers in waste management facing a growing challenge, it is vital to understand the complex relationship between waste prevention policies and individual behaviour regarding waste generation. This book examines that 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 (Sao Paulo, Sheffield and Tokyo) 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 will be of interest to students and researchers in the areas of environmental policy, management, sociology, psychology, geography, technology and waste studies.

A manifesto for a radically different philosophy and practice of manufacture and environmentalism
"Reduce, reuse, recycle" urge environmentalists; in other words, do more with less in order to minimize damage. As William McDonough and Michael Braungart argue in their provocative, visionary book, however, this approach perpetuates a one-way, "cradle to grave" manufacturing model that dates to the Industrial Revolution and casts off as much as 90 percent of the materials it uses as waste, much of it toxic. Why not challenge the notion that human industry must inevitably damage the natural world, they ask.
In fact, why not take nature itself as our model? A tree produces thousands of blossoms in order to create another tree, yet we do not consider its abundance wasteful but safe, beautiful, and highly effective; hence, "waste equals food" is the first principle the book sets forth. Products might be designed so that, after their useful life, they provide nourishment for something new-either as "biological nutrients" that safely re-enter the environment or as "technical nutrients" that circulate within closed-loop industrial cycles, without being "downcycled" into low-grade uses (as most "recyclables" now are).
Elaborating their principles from experience (re)designing everything from carpeting to corporate campuses, the authors make an exciting and viable case for change.
