The main purpose of biogas management in anaerobic digestion systems is centered around capturing and utilizing biogas for energy production. In an anaerobic digestion process, microorganisms break down organic matter in the absence of oxygen, which results in the generation of biogas, primarily composed of methane and carbon dioxide. This biogas can be harnessed and converted into renewable energy, reducing reliance on fossil fuels and contributing to sustainable energy practices.

Utilizing biogas for energy production has several advantages; it can be used to generate electricity, in combined heat and power (CHP) systems, or even as a fuel for vehicles if further refined. Effectively managing biogas not only maximizes energy recovery from waste materials but also minimizes greenhouse gas emissions associated with the release of untreated biogas into the atmosphere. Therefore, the focus on capturing and utilizing biogas emphasizes both environmental benefits and energy efficiency within wastewater treatment processes.
