Innovations in the Global Biogas Industry: Applications of Green Principles critically reviews the whole biogas supply chain from substrates to upgraded biogas. The book evaluates the application of green principles at each stage of biogas production and combines this with case studies and a review of the latest technological advances to produce a comprehensive assessment of the current state of the biogas industry. The first three sections of the book guide the reader through the whole supply chain of biogas production, from feedstock and waste management, to process design, plant design, operation, optimization, and end products. The sustainability of biogas industry operations is then addressed in-depth through a lifecycle assessment, alongside the techno-economics and safety considerations. Each section considers small-, medium-, and large-scale biogas plant related developments, and how green principles are applied at each scale. Finally, the critical element of biogas industry stakeholders is explored, which discusses financing mechanisms, policies and regulations, global markets, and governance issues relating to the biogas sector.
