Landfill Gas to Energy


What is landfill gas?

As solid waste in landfills decomposes, landfill gas is released. Landfill gas consists of approximately 50% methane, 42% carbon dioxide, 7% nitrogen and 1% oxygen compounds. Landfill gas is a readily available, local and renewable energy source that offsets the need for non-renewable resources such as oil, coal and gas.


Landfill Gas Usage

Landfill gas projects generate revenue from the sale of the gas and also create green jobs associated with the design, construction, and operation of energy systems. Once converted, landfill gas can be utilized in many ways: to generate electricity, heat, or steam; as an alternative vehicle fuel; or sold on the energy market as a renewable "green" power or gas.


• Electricity is the most widely used of the landfill gas projects. The electricity can be used for internal facilities or sold to external consumers.


• Direct-Use is used to replace non-renewable resources such as coal, oil, and natural gas.


• Cogeneration produces both electricity and thermal energy. This normally relates to steam or hot water and is very efficient.


• Pipeline Gas is a high Btu application. Landfill methane is processed to meet interstate pipeline standards and is injected into the delivery system. High value Btu systems generate premium value for landfills.
