Vertical flow constructed wetlands for wastewater and sludge treatment represent a relatively new and still growing technology. Vertical Flow Constructed Wetlands is the first book to present the state-of-the-art knowledge regarding vertical flow constructed wetlands theory and applications. In this book, you will learn about vertical flow systems with information about application and performance. Vertical Flow Constructed Wetlands also includes information on how different countries are applying the technology, with design guidelines to illustrate best practices worldwide. A focus on water conservation through reuse of treated water showcases the benefit of vertical flow construction, which has greatly increased the attractiveness of the technology in recent years. All state-of-the-art knowledge regarding vertical flow constructed wetlands gathered in one book A review of various constructed wetland approaches, including information about applications and performance, helps clarify what is currently known about constructed wetland principles and design Discussion of how to manage the treated wastewater leaving the vertical flow for increasing biodiversity, providing food and habitat for birds, and producing harvestable biomass or crops Includes case studies of constructed wetlands in developing countries

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 challenges 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 in achieving sustainability.

Volume 2, Circular Economy and Sustainability: Environmental Engineering, presents various technological and developmental tools 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 concepts to environmental engineering and management to promote sustainability goals in modern societies Approaches the topic on 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 both economic and societal progress

Despite the strong economic growth of the last decades, our modern global society is facing the existential threat of climate change. It is now realized that the linear economic model is not sustainable in the long run and cannot sustain the life standards. The new circular economy approach that is already under discussion suggests the adjustment of our priorities and the re-orientation of the future infrastructure investments. In this context, we are looking for new, innovative and sustainable solutions to increase the resiliency of our societies, to protect and restore the ecosystems, and to maintain the necessary economic growth without further undermining the planet’s boundaries. The well-being of coming generations will depend on our ability to adapt our economies to this challenge. In particular, transforming today’s cities into sustainable cities is one of the main adaptations that will be necessary. A holistic approach looking at cities from a system’s perspective is neededto achieve this goal.Nature-based solutions (NbS) serve exactly this ambitious and multi-factorial purpose due to their inherent ability not only to tackle climate change but also to provide a series of ecosystem services and social benefits. In the urban context, NbS can deal with main challenges such as urban heat islands, flooding, treatment of wastewater and runoff and food provision. At the same time, NbS can provide a series of ecosystem services beneficial for the environment and the society including clean water production, nutrient recovery, heavy metals retention and a broad range of plant-based materials. In the new circular economy paradigm, NbS can contribute to strategies for climate change adaptation and create a holistic resource management system for the urban biosphere.Thus, this book aims at providing a single reference that discusses the role and effectiveness of NbS in the urban environment and how these systems can contribute to the circular management of water, nutrients and resources towards resilient, sustainable and healthy cities. The scope of the book extends to various fields and disciplines such as the built environment, urban water and wastewater, resource recovery, urban farming, smart sensing, research and development, technology and innovation, society and governance. Research studies, pilot projects, and case studies are part of the book.
