The Process
What is methane?
Methane, a hydrocarbon gas (CH4), is a greenhouse gas and is explosive. Methane is generated by many forms of decomposition including landfills and swamps, and in the stomachs of cows.
What is landfill gas?
Landfills emit methane as a natural process of decomposition. Landfill Gas (LFG) contains a mixture of about 40-60 percent methane and the remaining mostly carbon dioxide (CO2).
The Environmental Protection Agency estimates that municipal solid waste landfills are the second-largest source of human-related methane emissions in the United States. At the same time, methane emissions from landfills represent a lost opportunity to capture and use a significant energy resource.
Our process
At a basic level, all of our processes filter out impurities, remove water, and compress the gas for transport. The three key solutions we provide—High Btu, Direct Use and Electric—vary in levels of complexity.
