Siloxanes are a family of man-made organic compounds that contain silicone, oxygen and methyl groups. Siloxanes are used in the manufacture of personal hygiene, health care and industrial products. As a consequence of their widespread use, siloxanes are found in wastewater and in solid waste deposited in landfills.
At wastewater treatment plants and landfills, low molecular weight siloxanes volatilize into digester gas and landfill gas. When this gas is combusted to generate power (such as in gas turbines, boilers or internal combustion engines), siloxanes are converted to silicon dioxide (SiO2), which can deposit in the combustion and/or exhaust stages of the equipment.
Source Test Ltd. provides landfill gas analysis for a range of compounds including:
- Siloxanes (Total as Si or Speciated)
- Gas Composition: C1 – C10, H2, He, N2, CO2, O2
- Total Sulphur Compounds (including H2S)
- Chlorine / Flourine
Other compounds such as VOC’s can be measured.
