explores the production of biohydrogen from food waste via anaerobic fermentation, focusing on effect factors, control methods and optimization. The book introduces food waste treatment and disposal technologies, including operational principles and process control. The authors discuss the use of aged refuse, the effect of several key factors on anaerobic gas production rate, process parameters optimization for enhancing biohydrogen yield, key factors in biohydrogen production from sewage sludge fermentation, and new developments in nutrition recovery from food waste.
