Gases extracted from landfills is utilised for its methane, but it also contains hydrogen sulphide that is corrosive and odourous. Armatec offers technologies to remove the hydrogen sulphide. Armatec high strength epoxy grouts are also used beneath compressors and turbines to secure them to the foundations.
Three Pratt & Whitney ‘jet engine’ turbines had to be firmly secured to its foundation with a grout that can handle any vibrations, physical loads, oil spills and the like. Plus the grout selected had to have a consistency that enabled it be to flowed around and under the hold down positions.
A retirement village was built on the site of an old landfill, closed many years earlier. The developer had to control methane emissions from the landfill, and installed a number of bores to extract gases from the landfill. The challenge was to dispose of the methane without any odour complaints from the hydrogen sulphide gas that came out of the wells with the methane.
