Add Green Power landfill gas to your energy mix.
When garbage decomposes in a landfill, a gas is produced. The gas consists of methane, carbon dioxide, oxygen, nitrogen, and non-methane organic compounds. Methane is considered a dangerous greenhouse gas. In a landfill, the harmful methane is destroyed by being burnt in a flare. Landfills are built with wells and underground pipes to draw the gas to the flare.
