Water Reuse Within A Circular Economy Context

Water Management and Circular Economy covers the role of water in the mainstream dimensions of society, economy, environment/ecology and technology. Along with the under conceptualization of the Circular Economy (CE), the book covers the role of recycling and reusing the otherwise lost sources of waste, gray or untapped water sources towards a second round of utility. This book bridges the gap between water inflows in nature with the wide spectrum of its potential applications in humanity. Sections cover direct and indirect entities conceptualized as “outflows, including water, energy, products and services to urban, suburban, rural and insular contexts of analysis. As such, this content will be important reading for Water Scientists, Water Managers, and civil engineers. Includes real-world applications and case studies to show how these policies can be adopted Presents global coverage, with a diverse list of contributors – all of whom are experts in the field Showcases a multidisciplinary approach, with editors from environmental and managerial backgrounds, thus helping to cross the bridge between social and science fields

The concept of circular economy is based on strategies, practices, policies, and technologies to achieve principles related to reusing, recycling, redesigning, repurposing, remanufacturing, refurbishing, and recovering water, waste materials, and nutrients to preserve natural resources. It provides the necessary conditions to encourage economic and social actors to adopt strategies toward sustainability. However, the increasing complexity of sustainability aspects means that traditional engineering and management/economics alone cannot face the new challenes and reach the appropriate solutions. Thus, this book highlights the role of engineering and management in building a sustainable society by developing a circular economy that establishes and protects strong social and cultural structures based on cross-disciplinary knowledge and diverse skills. It includes theoretical justification, research studies, and case studies to provide researchers, practitioners, professionals, and policymakers the appropriate context to work together in promoting sustainability and circular economy thinking. Volume 1, Circular Economy and Sustainability: Management and Policy, discusses the content of circular economy principles and how they can be realized in the fields of economy, management, and policy. It gives an outline of the current status and perception of circular economy at the micro-, meso-, and macro-levels to provide a better understanding of its role to achieve sustainability. Volume 2, Circular Economy and Sustainability: Environmental Engineering, presents various technological and developmental tolls that emphasize the implementation of these principles in practice (micro-level). It demonstrates the necessity to establish a fundamental connection between sustainable engineering and circular economy. Presents a novel approach linking circular economy concept to environmental engineering and management to promote sustainability goals in modern societies Approaches the topic of production and consumption at both the micro- and macro-levels, integrating principles with practice Offers a range of theoretical and foundational knowledge in addition to case studies that demonstrate the potential impact of circular economy principles on economic and societal progress

This book presents possible solutions for a circuler economy (CE) in the water and wastewater sector through an inventory of multidisciplinary knowledge with high scientific and practical importance which can contribute to support the transition to the CE model in water and wastewater sector. Water in modern studies exceeds being an important source for irrigation and drinking. It is now a significant source of renewable energy and a catalyst in most industrial and manufacturing products. The protection and sustainable management of water resources and water-based waste (as wastewater, sewage sludge, or sewage sludge ash) are important aspects of the CE, which is defined as a regenerative growth model that gives back to the planet more than it takes. Our book, entitled "Water in Circular Economy", delivers a comprehensive overview of the latest research covering the following aspects of water management from the perspective of the CE implementation: · Water as a key resource in the circular economy; · Innovative solutions in transition to the circular economy in water and wastewater sector; · Monitoring of circular economy implementation in water and wastewater sector.

This book presents new research on policy innovations that promote the development of the circular water economy. In contrast to the linear economy, the circular water economy promotes the reduction of water consumption, reuse of water, and recovery of resources from wastewater to not only increase resilience to climate change but also to reduce greenhouse gas emissions resulting from the provision of water and wastewater-related services. Providing a series of in-depth case studies of important locations in differing climates around the globe that have implemented a variety of policy innovations to develop the circular water economy, this book is a valuable resource for water and resource conservation managers, policymakers, international companies and organisations interested in the circular economy, environmental NGOs, researchers, as well as graduate and undergraduate students. · Systematically reviews policy innovations to develop the circular water economy · Illustrates how leading locations from around the world have developed the circular water economy to increase resilience to climate change while reducing emissions · Provides ‘best practices’ for other locations around the world aiming to implement the circular water economy

The United Nations World Water Assessment Programme (WWAP) is hosted and led by UNESCO. WWAP brings together the work of 31 UN-Water Members and 38 Partners to publish The United Nations World Water Development Report, (WWDR) series. The annual World Water Development Reports focus on strategic water issues. UN-Water Members and Partners, all experts in their respective fields, contribute the latest findings on a specific theme. The 2017 edition of the World Water Development Report focuses on 'Wastewater' and seeks to inform decision-makers, inside and outside the water community, about the importance of managing wastewater as an undervalued and sustainable source of water, energy, nutrients and other recoverable by-products, rather than something to be disposed of or a nuisance to be ignored. The report's title - Wastewater: The Untapped Resource - reflects the critical role that wastewater is poised to play in the context of a circular economy, whereby economic development is balanced with the protection of natural resources and environmental sustainability, and where a cleaner and more sustainable economy has a positive effect on the water quality. Improved wastewater management is not only critical to achieving the Sustainable Development Goal on clean water and sanitation (SDG 6), but also to other goals of the 2030 Agenda for Sustainable Development.

In recent times, the coalescence of different pressure has put a major strain on water supply globally. The level of water abstraction is reaching its natural limits, and this calls for a dramatic shift in water utilization concepts. This publication addresses the economic and financial issues and the methodology and procedures involved in the analysis of water recycling projects as part of a comprehensive water planning process. The issue is dealt within the wider context of water resources and covers human health, water quality, acceptability, institutional constraints, and other factors, all of which have economic implications and affect the feasibility of reuse schemes. The recycling of urban wastewater is a key link in Integrated Water Resource Management that can fulfill several different, but interrelated objectives. These are expressed as win-win propositions, delivering simultaneous benefits to farmers, cities and natural environmental systems, part of solutions to the urgent global problems of food, clean water, the safe disposal of waters and the protection of the vital aquatic ecosystems.

In arid and semi-arid regions, where water demand exceeds water availability, water security is becoming a significant concern not only related to water availability but also to rigorous and costly requirements to remove conventional and emerging contaminants from effluents discharging into drinking water sources or as water reuse becomes an alternate water supply for communities in these regions. Water and wastewater treatment demands a great amount of energy and resources, highlighting the need for novel applications of the circular economy concept. Circular Economy Applications for Water Security examines knowledge gaps, avenues of future research, and challenges related to the potential of enhanced underutilized/waste materials as a transition to circular economy applications for ensuring the proper quality of water. This book includes fundamental information and practical examples that helps to better understand the concepts included. The circular economy concept is helpful to incept sustainability in the water treatment processes. Every chapter includes the identification of knowledge gaps, avenues for further research, and challenges that guide readers towards real state-of-the-art analysis. Contributors are experts in their areas and will commit to explaining concepts in a user-friendly way without missing scientific rigor.
