The book aims to analyse and discuss the conventional and emerging treatments of digestate generated in the anaerobic treatment of organic waste. Thus, in the circular economy framework, the book will address up-to-date strategies for the treatment and resource recovery from anaerobic digestate.Anaerobic digestion is an expanding technology nowadays, especially when considering the thrust in ongoing research on the value-added products and energy recovery from biomass wastes, i.e., sludges, agro-industrial waste, animal waste, food waste and organic fraction of municipal solid waste, etc. Anaerobic digestate is a leftover and waste management authorities across the world do not have so many options for digestate management except using the digestate for land application as a fertilizer or composting. However, researchers and field engineers are still looking for robust options for digestate management. Thus, a timely book on digestate management will be an invaluable addition to this domain. The key features of the book include: the broad range of biomass waste covered, discussion of conventional to advanced technological options, and the inclusion of successful case studies.

Landfill leachate is a complex mix of organics, inorganics and heavy metals produced from the conventional and engineering landfilling practices.

The researchers and field engineers are still looking for robust options for leachate management. This timely book on landfill leachate management is a valued addition into this domain. The key features of the book include: broad range of treatment techniques covered, conventional to advanced technological options discussed, along with the inclusion of successful case studies.

This book reviews the recent challenges and future perspectives involved in the wastewater-based epidemiology (WBE) for COVID-19. The book aims to improve the monitoring of COVID-19 in wastewater by focusing on recent scientific studies in the surveillance and treatment of wastewater containing SARS-CoV-RNA, assessment of COVID-19 in the community and delivering a new scientific understanding of prevalence and re-emergence based on the WBE. It also provides a global perspective on effective detection methods for the analysis and interpretation of the RNA count of SARS-CoV-2 virus in wastewater and predicts the effects wastewater may have on the infection rate.Readers will find in this book case studies from France, India and Southeast Asian of non-invasive population-based monitoring of SARS-CoV-2 through sewage surveillance, and will learn more about the virus behaviour and transmission in different environmental settings. The significance of membrane technologies for virusremoval from water is also addressed in this book, as well as advanced techniques for identifying, quantifying, and characterizing SARS-CoV-2 in activated sludge and wastewater. The book provides a great interface to researchers such as microbiologists, environmental engineers, data scientists and civil engineers, emphasizing issues related to the current monitoring methodology. Furthermore, it also encourages researchers and policymakers by raising awareness of potential new methodologies for wastewater surveillance and accurate monitoring of COVID-19.
