Landfill gas monitoring is the process by which gases that are collected or released from landfills are electronically monitored. Landfill gas may be measured as it escapes the landfill ("Surface Monitoring") or may be measured as it is collected and redirected to a power plant or flare ("Collection System Monitoring").
Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste. Landfill gas is approximately forty to sixty percent methane , with the remainder being mostly carbon dioxide .
Landfill gas is cheaper than natural gas and holds about half the heating value at 16,785 – 20,495 kJ/m3 (450 – 550 Btu/ft3) as compared to 35,406 kJ/m3 (950 Btu/ft3) of natural gas. [13] Boilers, dryers, and kilns are used often because they maximize use of the gas, limited treatment is needed, and the gas can be mixed with other fuels.
A gas flare produced by a landfill in Lake County, Ohio. Gases are produced in landfills due to the anaerobic digestion by microbes. In a properly managed landfill, this gas is collected and used. Its uses range from simple flaring to the landfill gas utilization and generation of electricity. Landfill gas monitoring alerts workers to the ...
LoCI's system is designed to increase methane gas extraction from landfills. The software and hardware provide remote monitoring and control, versus historical practices, which require twice-monthly on-site monitoring and manual adjustments to extract the methane.
Landfill gas migration is a complex process in which gases produced by waste in a landfill move from the site of original deposition to other places via diffusion, usually from areas of high concentration to low.
Spickler Landfill: Marathon: During the remedial investigation of the Spickler Landfill site that took place in the late 1980s, some landfill gas was detected onsite, and asbestos was confirmed to be present in a landfill cover soil sample. In addition, leachate samples from the mercury brine pit contained elevated levels of calcium (3,340,000 ...
SWACO is governed by a nine member board. [8] It derives its revenue primarily through fees levied on the disposal of solid waste at SWACO facilities and from the collection and sale of landfill gas to Aria Energy, which refines the gas, pumps it into the gas pipeline and sells it.
