Economic Analysis of Landfill Gas Turbines

Publish Date: 2003

Microturbines are a new type of combustion turbine that can be used in stationary power generation applications. Microturbines, which were originally developed in the aerospace industry to produce auxiliary power on aircraft, are typically about the size of a refrigerator and can generate electricity in the range of 25 to 500 kilowatts (kW).

The commercial application of microturbines for landfill gas recovery began in early 2001. By the summer of 2003, it has been estimated that there will be about 100 microturbines operating on landfill gas in the U.S. and around the world.

In 2003, the SWANA Applied Research Foundation’s Disposal Group identified the issue of the economic feasibility of recovering landfill gas using microturbine technology as one of high importance to the group.

This technical memorandum has been developed by SWANA Applied Research staff to provide guidelines, based on currently available data and published information, regarding the economic aspects of landfill gas microturbines.
