Landfill Gas Analysis
Landfill gas (LFG) is produced from the anaerobic digestion of wet organic waste within a landfill. The gas produced contains methane, carbon dioxide and a combination of trace volatile organic compounds (VOCs); LFG contains approximately 500 trace compounds. Trace compounds can provide a variety of issues.
The gas may contain toxic chemicals, which can potentially pose a health hazard, and the vapour can constitute a nuisance when a number of compounds generated are odorous and emit a strong, unpleasant smell. The gas can also migrate through the soil and escape beyond the boundaries of the landfill site; methane is a potent and flammable greenhouse gas. Landfill gas is classified as a biogas and therefore utilised as a biofuel.
Lucideon has extensive experience in the analysis of landfill gas and, through our UKAS accredited testing laboratory No. 0013 (ISO 17025) offers a broad range of chemical analysis. Lucideon is also Accredited to conduct the sampling and testing of gas following the Environment Agency Technical Guidance Note LFTGN04. This guidance specifies a regime of sampling and analysis for a toxic and odorous list of chemicals which must be performed on all landfill sites at least once a year.
Passive sampling techniques are available for the personal and perimeter monitoring of trace VOCs.
Landfill gas testing services include:
- Bulk gas constituents (C1-C4 hydrocarbons, carbon dioxide, nitrogen, oxygen, hydrogen, helium)
- Hydrogen sulphide
- Organsulphur compounds
- Carbon monoxide
- Trace VOCs
- Alkyl esters
