AirScience Technologies was formed in 1993 from the merger of two companies, Canadian and American. After fifteen years of designing and building air pollution control systems for the primary and chemical industries, the company has refocused its activities on the renewable energy sector.

From the reduction of green gas emissions from landfills with its line of landfill gas flares, the company has since added the technologies for the desulfurization of biogas, the dehumidification of biogas, the purification of biogas and the production of renewable (green) natural gas through the removal of carbon dioxide.

The company is also active in the valorization of coke oven gas for the primary steel industry with production of high purity hydrogen.

The company is active in North America and in Asia where it has installed some of the largest landfill gas and coke oven gas valorization facilities.

AirScience Technologies offers the following technologies for the valorization of biogas, as well as the purification of process gases such as coke oven gas:
