Landfill gas is produced when refuse decomposes anaerobically (in the absence of oxygen). The duration and rate of gas generation vary from site to site.

Landfill gas is primarily a mixture of methane and carbon dioxide gasses in approximately equal amounts. Methane is combustible between 5 and 15 percent by volume, in air.

The primary purpose of most landfill gas collection systems is protection of human health, life, property, and the environment.

The LRI Landfill is filled in phases. New cells are opened once the previously active cells have been filled and at least partially closed. Horizontal gas collectors are installed as the waste is being placed and a temporary skid-mounted enclosed flame flare is installed.

This allows for the combustion of the small amounts of gas that are generated in the first few years of operation. Once the landfill gas is generated in sufficient quantities to support a large stationary flare, the first permanent flare will be installed.

The LRI Landfill monitoring system includes the installation of landfill gas probes around the landfill perimeter rather than at the property boundary. This provides for an added factor of safety for early detection of any possible migration issues.
