Biogas in the Circular Economy: Technology, Production and Applications explains biogas technology in the context of a circular economy, allowing for zero waste by valorizing digestate (residue) in a sustainable way. The book begins by discussing anaerobic digestion for biomethane production, including feedstocks, pre-treatments, innovative technologies, and the use of artificial intelligence in anaerobic digestion. Subsequent chapters present the latest technologies in biogas separation, purification, in-situ upgrading, and valorization of digestates in a circular economy context, namely as biofertilizers and energy recovery by thermochemical conversions. Carbon neutrality and challenges in biogas are discussed with the support of case studies.This new volume in the Woodhead Series in Bioenergy enables the reader to understand how biogas technology can be utilized to reach circular economy objectives. It will be valuable to all those with an interest in biogas technology, bioenergy, and bioeconomy, including researchers, advanced students, faculty, engineers, scientists, R&D, industry practitioners, and policymakers. - Presents advanced and sustainable approaches to digestate management for biogas production - Describes the latest technologies in biogas separation and purification as part of the circular economy - Explores biomethane and biohydrogen in the context of transport, power production, and the water-energy-food nexus - Addresses carbon neutrality challenges, lifecycle assessment, and cost-benefit analysis
