Biomethane Production from Vegetable and Water Hyacinth Waste explores the production of biomethane from vegetable waste and water hyacinth via anaerobic fermentation, focusing on effect factors, control methods and optimization. The book introduces principles and key technologies before proceeding into a deeper exploration of the fundamentals of municipal vegetable waste, such as composition, main indicators, experiment devices, and pretreatment. Processes to produce volatile fatty acids and resource recovery from anaerobic fermentation liquid and residue are described in detail. Other topics covered include the utilization of fermentation products, engineering design of a reaction tank, process parameters, and environmental and economic aspects. The practical, application-oriented approach of this book allows engineering researchers, PhD students, and industry practitioners in the field of biogas and biomethane production, biomass conversion, and waste management to immediately utilize the information it provides.
