Detailed explanation-1: -Biogas is generated during anaerobic digestion when microorganisms break down (eat) organic materials in the absence of air (or oxygen). Biogas is mostly methane (CH4) and carbon dioxide (CO2), with very small amounts of water vapor and other gases.

Detailed explanation-2: -Biogas is produced when bacteria digest organic matter (biomass) in the absence of oxygen. This process is called anaerobic digestion. It occurs naturally anywhere from the within the digestive system to the depth of effluent ponds and can be reproduced artificially in engineered containers called digesters.

Detailed explanation-3: -Biogas digesters receive organic matter, which decomposes in a digestion chamber. The digestion chamber is fully submerged in water, making it an anaerobic (oxygen-free) environment. The anaerobic environment allows for microorganisms to break down the organic material and convert it into biogas.

Detailed explanation-4: -Outputs from Biogas Digester: Biogas and Digestate Biogas consists of a relatively high percentage (50-75%) of methane (CH4), the main component of natural gas, as well as carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor, and traces of other gases.

Detailed explanation-5: -The precise composition of biogas depends on the type of feedstock and the production pathway; these include the following main technologies: Biodigesters: These are airtight systems (e.g. containers or tanks) in which organic material, diluted in water, is broken down by naturally occurring micro‑organisms.
