Landfill Gas

Landfills: Once an Eyesore; Now a Resource

Landfill gas (LFG) emitted from decomposing garbage is a reliable and renewable fuel option that remains largely untapped at many landfills across the Connecticut, despite its many benefits.

LFG is created when organic waste in a landfill naturally decomposes. This gas consists of about 50 percent methane (CH4), the primary component of natural gas, about 50 percent carbon dioxide (CO2), and a small amount of non-methane organic compounds.

The demand for renewable energy, or "green power," offers a number of opportunities to develop environmentally beneficial landfill gas (LFG) energy projects while providing a cost-effective and readily available source of clean energy. Converting LFG to energy offsets the need for non-renewable resources such as coal and oil, and thereby reduces emissions of air pollutants from conventional resources such as sulfur dioxide, a major contributor to acid rain.

Using LFG also helps to reduce unpleasant odors and explosion threats associated with LFG emissions, and it helps prevent methane, one of the most potent greenhouse gases, from migrating into the atmosphere and contributing to local smog and global climate change.
