About Landfill Gas

Landfill sites are filled with waste, methane gas is a by-product of the decomposing waste material. Landfill gas consists of approximately 20% – 50% methane, the remaining gases being carbon dioxide, nitrogen and oxygen.  

Factors determining the amount of gas and the performance of the site include;

  • Type of waste
  • Size of facility
  • Age of facility

Landfill gas is collected from within the waste dump via a number of vertical wells. A surface network of pipelines transports the gas to the gas treatment facility.  The treated landfill gas is burnt via gas engines to generate electricity or destructed via the flare system
