Biomethaneina

Biomethaneina is not a widely used term in mainstream energy literature. It may be a misspelling, a neologism, or a regional designation for topics related to biomethane. Because no standard definition is established in major reference sources, the article below describes biomethane, which is the typical substance most readers would encounter under this name.

Biomethane, or renewable natural gas (RNG), is methane-rich gas produced from organic matter. It is obtained by upgrading biogas—generated during anaerobic digestion or fermentation of agricultural residues, food waste, manure, or wastewater—to remove carbon dioxide and impurities. Typical upgrading methods include water scrubbing, pressure swing adsorption, membrane separation, or chemical absorption. The resulting gas meets natural gas quality specifications and can be injected into existing natural gas grids or used as a transport fuel after appropriate compression and storage.

Environmental and energy aspects: Biomethane offers a low-carbon alternative to fossil methane when feedstocks are managed sustainably, contributing to waste treatment and rural development. Lifecycle emissions depend on feedstock, digestion efficiency, and gas usage. In many regions, biomethane qualifies for renewable energy incentives and must meet regulatory sustainability criteria and gas-quality standards.

Because "biomethaneina" is not a standard term, readers should consult local or institutional sources for precise definitions. See also: biomethane, renewable natural gas, anaerobic digestion.
