Biogas flare

Biogas produced by anaerobic fermentation is a byproduct of normal operations at modern wastewater treatment plants, ethanol plants, livestock farms, landfills, and facilities handling organic industrial wastewater. Its primary components consist of 50–65% methane and 30–50% carbon dioxide, along with hundreds of other constituents such as water vapor, sulfides, and nitrides. Methane is one of the primary greenhouse gases. Biogas not only pollutes the environment but also poses serious safety hazards; therefore, centralized treatment of anaerobic biogas is necessary.

For facilities or sites with relatively low gas production, biogas is typically incinerated via biogas flares. Biogas flares serve to enhance site safety, increase public acceptance, reduce odor pollution, and mitigate the greenhouse effect.
