QuestAir Technologies Inc. HAS announced that it has received an order for aN M-3200 PSA system to recover pipeline-grade methane from biogas generated by an anaerobic digester in Lavigny, Switzerland.

Verdesis Suisse SA has purchased QuestAir’s system as part of a new plant that will recover methane from biogas generated by the anaerobic digestion of organic wastes at the Lavigny site. The methane recovery plant will be owned and operated Cosvegaz S.A., a Swiss gas utility, and product methane from the plant will be injected into the local natural gas distribution grid operated by Cosvegaz.

Jonathan Wilkinson, President and CEO of QuestAir said: “We are extremely pleased to secure our first sale into the European biogas market, which represents an exciting growth opportunity for QuestAir. We have seen growing interest across the EU in the use of renewable sources of methane to supplement or replace imported natural gas. In addition, government programs in several EU countries are promoting the use of biogas as a carbon neutral source of compressed natural gas (CNG) transportation fuel for buses and cars.”

“QuestAir’s methane recovery systems offer a compact solution for cost-effectively removing carbon dioxide and other impurities from biogas, recovering high purity methane for high value end-uses,” Wilkinson said.
