Leachate Gas Management System Landfill Gas Recovery & Monitoring 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, facilities have been installed to recover the gas for beneficial uses or proper treatment so that it will not harm the environment. The movement of landfill gas is monitored and controlled throughout the operation and aftercare of the landfills 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. Landfill gas is also used as a source of heat energy for leachate treatment at landfills. For the case of NENT Landfill, facilities have been installed for the treatment and export of landfill gas for off-site beneficial uses. Any residual gas at landfills would be flared at very high temperature.
