text: Landfill gas is a by-product of microbial activity and is formed from the anaerobic decomposition of organic waste materials. It is comprised primarily of methane and carbon dioxide. The methane which contains the chemical energy for power is typically at 40-60% concentration. This biogas, if released to atmosphere, is a potent greenhouse gas. However if it is utilised in a gas engine, emissions are reduced and renewable electricity is produced, with the added benefit of converting a waste material into a useful fuel.
  Using landfill gas for power provides base-load electricity; unlike wind power and solar, landfill gas can be used to deliver continuous, stable supplies of electricity to the power grid.
