In many landfills the existing gas either cannot be used, or may be used only to a limited extent, due to high levels of pollutants being present. Project profitability is only achievable if the presence of pollutants like siloxanes or sulphur in the gas is contained. Clean gas lowers operating risks and costs and promotes higher project returns, through continuity of operations.
Besides other trace elements, organic silicon-compounds such as siloxans are critical elements in landfill gas. When combusted, Siloxanes transform into silicon-dioxides in the combustion chamber and deposit harmful sediment on the machinery parts.

The crystalline deposits work like sand on the flexible motor components. For essential machinery, this can lead to the:

  • Lapse of warranties
  • Invalidation of insurance coverage
  • Higher equipment abrasion
  • Higher maintenance and operating costs
  • Equipment failure etc.

Green Gas provides gas cleaning solutions including:

  • Gas Cooling (which serves to dehumidify the gas)
  • Gas Scrubbing
  • Gas Drying (an additional step to avoid the gas becoming humid again)
  • Gas Cleaning by active coal (the gas is filtered via active coal).

We are able to provide an innovative gas cleaning system, which is superior to conventional systems in terms of cleaning power and costs. It is based on gas scrubbing via a specially developed additive, which dissolves most of the organic silicon-compound.
