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.

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 provides insight into how governments are using a variety of innovative fiscal and non-fiscal instruments to develop circular economies with significant economic and environmental benefits. It emphasises the urgent need for these circular economies and to move away from our current, linear model that has led to environmental degradation, volatility of resource prices and supply risks from uneven distribution of natural resources. Natural Resource Management and the Circular Economy illustrates how governments have promoted the development of an economy that can provide substantial net material savings; mitigate price volatility and supply risks; and improve ecosystem health and long-term resilience of the economy. Through a series of case studies, it details the various innovative policy instruments which can be utilised, including regulations; market-based instruments; incentives; research and innovation support; information exchanges; and support for voluntary approaches. The book also proposes a series of best practices for different countries, both developed and developing, who are implementing their circular economy.

The concept of a circular economy has been gaining increasing attention in recent years. Many of the sources of chemicals we have become reliant on are dwindling and the accumulation of waste products poses a serious environmental problem. By recovering resources from these waste materials, we can reduce our dependence on virgin feedstocks that may not be sustainable as well as reducing the quantity of material going to landfill sites. Incorporating different perspectives from a global authorship, this book aims to introduce systems thinking to the field of waste and resource management. The topics covered range from the use of biogeochemical processes in resource recovery to the application of engineered nanomaterials, with information relevant to both academia and industry. The broad range and cross-disciplinary nature of the topics in this book make it a valuable resource for those working in circular economy research, green chemistry and waste and resource management.

The EIB Circular Economy Guide aims to promote a common understanding of circular economy, and raise awareness about and promote circular solutions. The Guide provides information about EIB's lending and advisory activities in this field, and communicates our vision of how the EIB can further support the transition to a circular economy. The Guide is a living document that will be updated in response to our evolving understanding of circular economy needs, opportunities and risks, and growing experience with the appraisal and financing of circular economy projects.

Cities and regions play a fundamental role in the transition from a linear to a circular economy, as they are responsible for key policies in local public services such as transport, solid waste, water and energy that affect citizens’ well-being, economic growth and environmental quality. This synthesis report builds on the findings from 51 cities and regions contributing to the OECD Survey on the Circular Economy in Cities and Regions and on lessons learnt from the OECD Policy Dialogues on the circular economy carried out in Groningen (Netherlands), Umeå (Sweden), Valladolid (Spain) and on-going in Glasgow (United Kingdom), Granada (Spain), and Ireland.

"The Circular Economy in Europe presents an overview and a critical discussion on how circularity is conceived, imagined and enacted in current EU policy-making. In 2013, the idea of a circular economy entered the stage of European policy-making in the efforts to reconcile environmental and economic policy objectives. In 2019 the European Commission declared in a press release that the Circular Economy Action Plan has been delivered. The level of circularity in the European economy, however, has remained the same. Bringing together perspectives from social sciences, environmental economics and policy analysis, The Circular Economy in Europe provides a critical analysis of policies and promises of the next panacea for growth and sustainability. The authors provide a theoretical and empirical basis to discuss how contemporary societies conceive their need to re-organise production and consumption and explores the messy assemblage of institutions, actors, waste streams, biophysical flows, policy objectives, scientific disciplines, values, expectations, promises and aspirations involved. This book is essential reading for all those interested in understanding how ideas about the circular economy emerged historically, how they gained traction and are used in policy processes, and what the practical challenges in implementing this policy are"--
