Geomembrane Technologies Inc. IS NOW THE exclusive distributor of VSO Biogas Technologies’ gasholders IN the United States and Canada

Double-membrane gasholders reliably capture methane gas, a naturally-occurring component of biogas generated from anaerobic digestion.

Fredericton, New Brunswick, Canada (July 21, 2015): Geomembrane Technologies Inc. (GTI) is proud to announce they are now the exclusive distributor of double-membrane gasholders, manufactured by VSO Biogas Technologies, in the United States and Canada. GTI's cover experts can deliver, install, and commission these gasholders, and provide advice on how to maximize the use of biogas.


Double-membrane gasholders reliably capture methane gas, a naturally-occurring component of biogas generated from anaerobic digestion. They safely store and regulate the use of biogas, which can be used in engines and combined heat and power (CHP) units for electricity and heat at wastewater treatment plants, municipalities, and farms. Biogas can be also be used in boilers for process heat and steam or, in some cases, sold to a local utility for profit.

Made from flexible composite materials using high-frequency welding, the gasholders consist of an inner membrane that holds the biogas and an outer membrane that protects the inner membrane from the elements and regulates internal pressure. They range in size from 1,800 ft3 to 180,000 ft3 (50 m3 to 5,000 m3) and can be either pad mounted for solid structure digesters, or mounted directly on round digester tanks.
