In today’s world, trapped greenhouse gases are believed to be the sole or primary cause of global warming, threatening the earth’s very future. The gas that gets the most notoriety is carbon dioxide (CO2).  While this gas does show a massive negative impact on the environment, there is another gas that has 21 times the global warming potential (GWP)of CO2 – that gas is methane (CH4), which has a lifetime of 12 years in our atmosphere.  Methane shows 21 times the potential of carbon dioxide to trap harmful infrared radiation in our atmosphere, unnaturally warming the earth and disrupting ecosystems vital to life.

Methane gas is produced as a byproduct of anaerobic decomposition of organic material (decomposition taking place without oxygen).  Forty percent of methane emissions in our atmosphere originate from natural sources such as wetlands, oceans, and hydrates.  However, humans account for a full sixty percent of the world’s methane production, and the majority of human-induced methane can all be traced to one target area: landfills.

Landfills are large areas consisting of millions of tons of waste, all decomposing and producing lethal amounts of methane. When left uncollected, methane is devastating to the environment, climate, and earth as whole. It is a major source of odor and contributes to smog and ozone depletion in the atmosphere.  If collected and properly treated, landfill gas can be a long-term renewable source of energy, displacing the world’s shrinking fossil fuel reserves in gas pipelines all over the world, while almost completely eliminating the environmental consequences of solid waste decomposition.

Landfill Gas Operations
Landfill gas (LFG) is produced when microorganisms break down organic material in the landfill, and is comprised of approximately 50-60 percent methane and 40-50 percent carbon dioxide. At most landfills in the United States, these greenhouse gases are simply burned off, or “flared.” The gas is extracted from landfills by drilling wells, and then using a blower, flare, or vacuum system to route this gas into a central gas-collecting station. Once this gas is collected, it is either “flared” (burned away into nothing), or properly treated according to the desired outcome.

seeking opportunities to develop projects for processing LFG to pipeline-grade natural gas. Enpower is prepared to provide a complete solution to recover valuable methane gas for delivery into a nearby natural gas pipeline or for the production of LNG, creating benefits for the landfill owner and the surrounding community. Enpower will work with you to determine if your landfill is a candidate for a LFG to high BTU gas facility. We provide complete services, including design, finance, build, own, and/or operate.
The landfill owner can expect to benefit from the project in several ways. These include:
•             Generating additional revenue.
•             Minimizing/controlling landfill odors.
•             Creating “green” energy.
•             Complying with environmental regulations.
•             Enhancing community image.
