In 2009, the Board of Waste Management for the Mauricie region of Quebec, Canada (RGMRM) found a biogas purification solution through an Eco-Tec Inc. system known as BgPur, which uses a patented, high efficiency gas-liquid contacting process, allowing H2S to be absorbed and the gas purified for reuse in power generation, cogeneration and heating applications.
The aim was to purify the landfill gas for a greenhouse on site, which also is RGMRM’s customer. The gas was to be converted into a usable source of heat for the greenhouse, especially during the
winter months, and into a source of CO2 to enrich the hydroponic tomatoes grown there. In turn, the renewable source of carbon dioxide, present in the biogas, would eliminate the costs ssociated with having to purchase and maintain CO2 for the operation.
Today, the BgPur system continues to successfully remove more than 99 percent of hydrogen sulfide from the gas at RGMRM’s landfill, for reuse in its internal processes. Located among the Laurentian Mountains, RGMRM is the board of management of waste for the Mauricie region of Quebec, Canada, which has a population of approximately 300,000 people. The public body was formed through an amalgamation of several municipalities
entrusting it to manage the region’s waste. RGMRM’s mission includes respect for the environment, sound management
principles and a focus on innovation.
It was RGMRM’s first partnership with fellow Canadian
manufacturer, EcoTec Inc., located in Pickering, Ontario. Eco-Tec’s in-house Research and Development facility has been building industrial purification solutions since 1970, and has installed more than 1,500 systems in more than 55 countries.
