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.
A gas flare produced by a landfill in Lake County, Ohio. 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.
These gases can include methane (CH 4), carbon dioxide (CO 2), hydrogen (H 2), and volatile organic compounds (there are approximately 500 others that can be present in trace forms) from the waste on site and its degradation over time. Steps must be taken to prevent this migration from the landfill site as it might enter buildings in the vicinity.
The amount of methane that is produced varies significantly based on composition of the waste. Most of the methane produced in MSW landfills is derived from food waste, composite paper, and corrugated cardboard which comprise 19.4 ± 5.5%, 21.9 ± 5.2%, and 20.9 ± 7.1% respectively on average of MSW landfills in the United States.

The Kaveri delta coal-bed methane extraction project is a series of projects to extract methane gas and hydrocarbon from coal-bed by using hydraulic fracturing in the Kaveri river basin in Tamil Nadu, India.
America’s landfills—and the environmental havoc they create—are sizable. There are roughly 1,200 landfills currently in operation, and on average, each one takes up about 600 acres of land ...
Monitoring of the landfill gas itself can be used diagnostically. When there is concern regarding the possibility of an ongoing subsurface oxidation event, or landfill fire, the presence in the landfill gas of compounds that are more stable at the high temperatures of such an event (above 500 °C) can be evidence for such a process occurring.
