 Biogas is a renewable gaseous fuel containing approximately 50-70% methane and 30% to 40% carbon dioxide. Biogas is produced as a by-product from the decomposition of organic waste in landfills and anaerobic digesters that process agriculture waste and municipal waste water. In addition, anaerobic digestion of animal manure and other agricultural wastes offers a number of additional benefits to farmers, including reducing air and water pollution, odor management and the production of environmentally benign co-products including organic fertilizer and animal bedding material.
To date, electricity generation has been the most common option for energy recovery from biogas, accounting for over 60% of the operational landfill gas processing plants in the United States. However, the recovery of pipeline grade methane or liquefied natural gas ("LNG") from landfill gas is also viable using gas purification technology.
 QuestAir Technology
A key step in the processing of biogas is the separation of carbon dioxide present in the gas. The QuestAir™ M-3100 and M-3200 PSA systems offer compact, low-cost, carbon dioxide separation solutions for lower capacity applications (up to 4,000 NCMH product methane). The compact design and optimized performance of QuestAir’s PSA is an excellent fit with biogas upgrading plants.
