Materials Testing - Landfill Gas Testing

A landfill using Zeomatrix technologyThe conversion of landfills’ natural gas to energy is an emerging alternative fuel industry. With an increasing need for more energy sources, LFG fuel is both a practical and promising option. It provides a new fuel resource as well as a solution to the problem of increasing waste production in the United States, which currently fills over 2,000 landfills around the country.

The convenience of landfill gas containment is one of its most positive attributes. Not only is LFG readily accessible, but its removal from landfills is a benefit to the environment. Landfills contain a variable mixture of organic gaseous compounds, some of which are contaminants and are occasionally radioactive. The heterogeneous nature of landfills makes them unpredictable, which adds an extra layer of difficulty to processing the desired gases. One particularly problematic gas is sulfur, the source of landfill gas odor.

Landfills produce large amounts of gases that are hazardous when they are released into the air. Fires, environmental contamination and even explosions can occur around landfills. For these reasons, certain state regulations require the periodic testing of the gas to ensure safety. By removing the gas entirely from the landfill, dangers can be avoided altogether. In this way, the utilization of LFG is the solution to an environmental safety problem and to the country’s current alternative fuel problem.

The PDC is one of the only landfill gas testing facilities in the northeast, offering its customers the convenience of a laboratory close by and rapid turn-around for results. Our laboratory is equipped with sophisticated gas chromatographs (GC’s), capable of precisely determining the identity and quantity of each chemical component present in the sample.  The PDC’s analytical laboratory can help you meet the requirements of state Municipal Solid Waste (MSW) regulations for your landfill. Our laboratories  also offer LFG testing to facilitate the production of fuel at LFG burning plants.

Examples of Tests we perform include:

  • Gas Component Analysis in conformance with ASTM 1945 (methane, carbon dioxide, nitrogen, oxygen, hydrogen sulfide, GHV, relative density)
  • Sulfur Analysis in conformance with ASTM 5504 (hydrogen sulfide, carbonyl sulfide, methyl mercaptan, ethyl mercaptan, dimethyl sulfide, carbon disulfide, i-Propyl mercaptan, t-Butyl mercaptan, ethyl methyl sulfide, thipphene, diethyl sulfide, dimethyl disulfide, ethyl methyl disulfide, diethyl disulfide, Total sulfur)
