Landfill Gas Management

Waste degradation produces landfill gas in significant quantities. Landfill gas is made up of several gases and chemicals such as methane which are potential flammable and harmful to health. At the landfills, wells have been installed to extract the gas and burn it off at very high temperatures so that it will not harm the environment.

The movement of landfill gas is monitored and controlled throughout the operation of the landfill to reduce atmospheric emissions, to minimize the release of odourous emissions and to restrict subsurface migration.

Landfill Gas Utilisation Plants

One beneficial use of landfill gas is to generate power. The generators at landfills provide the power for on-site usage. Surplus gas is flared in the flaring plant.
