Landfill Gas

Landfill gas is generated from the breakdown of municipal solid waste. There are hundreds of municipal landfills, all of which produce a mixture of methane and carbon dioxide with traces of nitrogen, oxygen and other gases. In active landfills, these gases are extracted from multiple wellheads and collected through a network of pipes to a common header pipe. Typically, the gas is about half methane and half carbon dioxide and can be used to replace traditional fossil fuels to heat buildings, boilers and kilns, run generators to make electricity, and even produce fuel to power vehicles. A typical municipal landfill can produce enough energy from landfill gas to power thousands of homes for many years. In addition to generating power, landfills are frequently involved with Carbon Offset projects. There are over 1000 landfills worldwide where landfill gas is collected. This collection reduces greenhouse gas emissions and accrues emissions credits, both of which meet the Environmental Protection Agency’s (EPA) reporting standards, and comply with the Kyoto protocols.

Sage Thermal Mass Flow Meters help quantify the captured emissions by measuring the mass flow rate, even at very low flows, and by providing a very easy way to conduct the required periodic calibration field checks with its unique In-Situ Calibration procedure. In addition, Sage provides Flare Gas Flow Meters, Engine Flow Meters, Wellhead Monitoring Portable Datalogging Flow Meters, and a variety of other Thermal Mass Flow Meters that are involved in landfill gas monitoring and reporting.
