BIOGAS
Biogas is the product of a biological process called anaerobic digestion. In the absence of oxygen, anaerobic bacteria decompose organic matter and produce a gas mainly composed of methane (70 to 75%) and carbon dioxide called biogas, having a Btu value of approximately 750 / cubic foot. This gas can be compared to natural gas which is 99% methane. Similar to natural gas, methane captured by a biogas recovery system can be substituted for natural gas to heat or produce electricity and therefore reduce greenhouse gas emissions to the atmosphere. Biogas collected can be used as energy source for generators, boilers, burners, dryers or any equipment using natural gas. This equipment will require minor modifications to the existing gas train, due to the lower Btu value, to run on biogas.
With rising natural gas and energy costs, capturing and utilization of biogas is an economical source of energy while addressing growing concerns on climate change and global warming. If biogas is not recovered and utilized, methane will significantly contribute to the greenhouse gas (GHG) effect which is approximately 20 times more severe than carbon dioxide.
