Upgrading Biogas to RNG

Special Section
September
2021

Favorable policies and environmental benefits are earning renewable natural gas (RNG) market acceptance. Upgrading technologies are critical to producing RNG that is ready to serve this market.

Renewable natural gas (RNG) is primarily composed of methane, as well as trace gases, such as hydrogen sulfide, carbon dioxide, and other volatile organic compounds (VOCs). RNG feedstocks can be sourced from municipal wastewater treatment plants, large agricultural farms, solid waste landfills, and organic food waste generators. These feedstocks are processed and sealed in an anaerobic digester, where a host of bacteria convert the organic material into a biogas that is predominantly methane. The biogas is processed to remove impurities, thus upgrading the raw gas to RNG.

This article focuses on the technologies used to upgrade biogas to RNG. It also highlights the environmental benefits of RNG and the policies that are helping it to earn market acceptance.
