Clean Energy and Resources Recovery: Biomass Waste Based Biorefineries, Volume One presents the technological options for energy and resources recovery from all types of organic wastes. The book addresses municipal and industrial sludges, municipal solid waste, agro-residue, animal wastes, industrial waste, forestry residue, and algal biomass, and provides a global overview of biomass waste production, waste handling issues and related GHG emissions and climate change, legislative waste management guidelines, biomass composition, and conventional methods for biomass waste treatment. For each biomass waste, chapters cover energy and bio-based products recovery, pre-treatment methods, process microbiology, community dynamics, co-digestion, reactor design and configuration, and techno-economic evaluation.

Case studies on upscaling technology and pilot and industry scale implementation are included, alongside step-by-step calculations that integrate practical field data and regulatory requirements into the environmental design process. Finally, future trends and developments in advanced biotechnological concepts for biomass waste processing and management are also discussed.

Clean Energy and Resource Recovery: Wastewater Treatment Plants as Bio-refineries, Volume 2, summarizes the fundamentals of various treatment modes applied to the recovery of energy and value-added products from wastewater treatment plants. The book addresses the production of biofuel, heat, and electricity, chemicals, feed, and other products from municipal wastewater, industrial wastewater, and sludge. It intends to provide the readers an account of up-to-date information on the recovery of biofuels and other value-added products using conventional and advanced technological developments. The book starts with identifying the key problems of the sectors and then provides solutions to them with step-by-step guidance on the implementation of processes and procedures. Titles compiled in this book further explore related issues like the safe disposal of leftovers, from a local to global scale. Finally, the book sheds light on how wastewater treatment facilities reduce stress on energy systems, decrease air and water pollution, build resiliency, and drive local economic activity.As a compliment to Volume 1: Biomass Waste Based Biorefineries, Clean Energy and Resource Recovery, Volume 2: Wastewater Treatment Plants as Bio-refineries is a comprehensive reference on all aspects of energy and resource recovery from wastewater. The book is going to be a handy reference tool for energy researchers, environmental scientists, and civil, chemical, and municipal engineers interested in waste-to-energy. Offers a comprehensive overview of the fundamental treatments and methods used in the recovery of energy and value-added products from wastewater Identifies solutions to key problems related to wastewater to energy/resource recovery through conventional and advanced technologies and explore the alternatives Provides step-by-step guidance on procedures and calculations from practical field data Includes successful case studies from both developing and developed countries

Sustainable Treatment Technologies for Pre- and Poly-flourakyl Substances provides comprehensive details about per- and poly-fluroalkyls substances (PFASs), which are highly toxic and bio-accumulative substances that do not biodegrade easily or cannot be neutralized under normal environmental conditions. It discusses their occurrence in water, wastewater, and aquatic environment, their bioaccumulation in plants, environmental impacts and various remedial technologies for their treatment and management. All the chapters provide state-of-art information about PFASs, describing their identification methods, characterization and present critical analysis of the treatment methods such as physical, chemical, biological, hybrid and advanced systems. This book is a ready reference for the environmental engineers, municipal engineers, environmental practitioners, policy makers, and planners; it is also a practical guide for industrial engineers, government bodies and ecologists as well as for researchers. Describes occurrence of PFASs in aquatic environment and on plant Provides details on identification methods and characterization of PFAS Describes physical, chemical, biological, hybrid and advanced system treatments for PFASs Covers regulatory aspects on PFASs First dedicated book on PFASs

Sludge Management provides up-to-date information on sludge treatment, reuse and disposal. A comprehensive coverage of all issues related to sludge management is included with local through global coverage of all sludge management practices. Conventional to advanced technologies for sludge management with available case studies from both developing and developed countries are covered in this book. Given the responsibility of engineers to develop the technological tools to meet the increasingly stricter standards for sludge treatment and disposal, the main attraction of the book principally relies on its technical content that reviews all the points to be considered in sludge management from engineering and technological perspectives.
