This book provides a comprehensive exploration of the role of constructed wetlands in sustainable wastewater treatment and their contribution to the emerging concept of the biocircular economy. The book is divided into three parts. Part I covers the fundamentals, basic design, efficiency, maintenance, limitations, performance assessment, and sustainability of constructed wetlands. It also provides an overview of the current situation. Part II is dedicated to recent advancements and novel applications of constructed wetlands for wastewater treatment, including various emerging technologies, bioelectrochemical systems. The last part concludes with a global scenario, challenges, life cycle assessment, and techno-economical analyses of constructed wetlands. It also provides the information on the techniques and methodologies that facilitate the integration of wastewater treatment technologies; the bibliometric overview of the research progress and challenges; policy landscape; global perspectives; and green circular economy. The book is a valuable resource for researchers, practitioners, and policymakers interested in advanced sustainable wastewater treatment solutions.

Dr. Neeraj Kumar Singh is a research associate in the Department of Bioscience and Bioengineering, Indian Institute of Technology Roorkee, India. He received his M.Phil. and Ph.D. in environment and sustainable development from the Central University of Gujarat, India. He has worked under various projects funded by the Government of India and many other organisations for the development of microbial fuel cells, bioelectrochemical systems, bio-hydrogen, and bioethanol production. He has published research papers and book chapters in reputed journals. He has developed various pretreatment strategies of lignocellulosic biomass for value-added product recovery and methane suppression for enhanced hydrogen production in bioelectrochemical systems. His research interests include wastewater treatment, biohydrogen, and bioethanol production from agriculture biomass.

Dr. Maulin P. Shah is interested in genetic adaptation processes in bacteria, the mechanisms by which they deal with toxic substances, how they react to pollution in general and how we can apply microbial processes in a useful way (for example, bacterial bioreporters). One of his major interests is to study how bacteria evolve and adapt to use organic pollutants as novel growth substrates. His research work focuses on the impact of industrial pollution on microbial diversity in wastewater though cultivation dependant and cultivation independent analyses. His major work involves isolation, screening, identification and genetic engineering of microbes for the degradation of hazardous materials. He has more than 450 research publications in highly reputed national and international journals. He manages the research programs at Enviro Technology Ltd., Ankleshwar, India. He also serves as a reviewer in various academic journals.

Dr. Smita S. Kumar is faculty in the Department of Environmental Studies, Central University of Haryana in India. She has a Ph.D. in environmental science and engineering and has teaching and research experience of more than 10 years. Prior to the current position, she was faculty at the J.C. Bose University of Science & Technology, YMCA, in Faridabad, India. She pursued her postdoctoral research at the Centre for Rural Development and Technology, Indian Institute of Technology, Delhi, where she worked on the conversion of emerging water pollutants from agrochemical and pesticide industries into green energy by microbial fuel cell technology. Her research interests include environmental pollution assessment and abatement, waste and wastewater treatment, sustainable bio-energy production, landfill leachate treatment, and bioremediation. She has published more than 100+ peer-reviewed journal articles, conference proceedings, book chapters, and edited books.
