Basics of Anaerobic Digestion 凤轻 Woven into these life lessonsAnaerobic Digestion is a series of chemical reactions during which organic material is decomposed through the metabolic pathways of naturally occurring microorganisms in an oxygen depleted environment. In nature, this type of breakdown typically occurs in warm, wet, and dark environments, such as in the digestive tracts. The microorganisms are exploited in the biotechnological process of anaerobic digestion both to reduce the pollution caused by
