Camera helps lessen environmental impact of landfill site

At the company’s main site at Drammen (Norway), Lindum has a biogas production plant and a huge landfill consisting of selected solid waste covered with clay layers.

The methane gas produced by the landfill is extracted and used for power production and residential heating.

Methane is an odourless, environmentally harmful gas which is created as a result of pressure formed in the landfill. However, the landfill also discharges hydrogen sulphide (H2S) a malodorous gas that at times has annoyed surrounding residential areas.

To detect these gas leaks, Lindum acquired a FLIR Systems GF320 gas imaging camera, an infrared camera that traces and visualizes about twenty VOC gases including methane.

The landfill, with a surface of approx 10 hectares, is inspected twice a week at dawn for about one hour.

The FLIR GF320 instantly shows gas leaks, visualized as black or white plumes. Landfill workers then cover the leaks with clay and an ironed mass to neutralise the sulphide odours.

The FLIR GF320 gas imaging camera is also used for inspection of the biogas production piping on a weekly basis.
