Detect methane leaks in a landfill with FLIR's gas detection cameras (OGI).

Economic and environmental concerns require the implementation of an increasingly simplified waste disposal, treatment, neutralization and recycling process. Waste treatment companies are progressively becoming energy suppliers. GasFindIR infrared gas detection cameras support these trends and provide immediate and tangible results. 

Lindum Ressurs og Gjenvinning AS, based in Norway, specializes in waste treatment solutions. Lindum follows a consistent process of converting waste into energy by composting, recycling and landfill gas extraction for energy production and residential heating. The company's main site, located in Drammen about an hour's drive from the Norwegian capital of Oslo, has a biogas production plant and a huge landfill consisting of separately collected solid waste that is covered by layers of clay.

The methane gas produced by the landfill is extracted and used for energy production and residential heating. Methane is an odorless, environmentally harmful gas that is created as a result of the pressure that forms in the landfill. In addition, the landfill releases hydrogen sulfide (H2S), a foul-smelling gas that is sometimes a nuisance to nearby residential areas.

To detect major leaks, Lindum decided to purchase equipment with Teledyne FLIR's GasFindIR technology, an infrared camera that tracks and visualizes approximately 20 volatile organic compound gases, including methane.

The landfill, which covers an area of approximately 10 hectares, is inspected twice a year at dawn for one hour. The GasFindIR camera instantly shows gas leaks, which are visualized as white or black smoke. Landfill workers then cover the leaks with clay and a pressed mass to neutralize sulfur odors.

The GasFindIR is also used to perform weekly inspections of biogas production pipelines. Lindum, convinced of the advantages of the camera, offers inspection services with its GasFindIR to landfill management companies, as images can be easily recorded and stored with a standard video camera.

"The efficiency of the GasFindIR cameras can be easily quantified: we detect four to five leaks per week and have reduced odor development considerably," says Aud Helene Rosenvinge, operations manager.

"We consider GasFindIR gas detection cameras to be an indispensable maintenance and safety tool," explains Rosenvinge, who adds that he estimates cost savings of at least 12,000 euros per year.
