Landfill Gas

What is landfill gas?

Landfill gas (LFG) is an alternative energy source that is obtained from waste matter dumped in a landfill. When organic solid waste decomposes in a landfill, the process is accompanied by the release of methane gas. These emissions can be trapped and used as a source of energy. Methane makes up nearly 50% of landfill gas. The other 50% is carbon dioxide. In addition, there are small amounts of non-methane organic compounds (NMOC).
