Anaerobic digestion
Anaerobic digestion is the way microorganisms break down organic matter without oxygen.[1][2] This process happens naturally, but it is called anaerobic digestion when it is supported and contained.
An anaerobic digester is an industrial system that supports this process. Biodegradation to treat waste is one of the main purposes. Generating biogas to provide fuel is another. It also produces soil improving material.[3]

Schematic of an anaerobic digester as part of a sanitation system. It produces a digested slurry (digestate) that can be used as a fertilizer, and biogas that can be used for energy.
