Guild Associates, Inc. products

Biogas from digesters (waste water treatment plants and other digesters) typically have a methane (CH4) content of about 50-60% with the remaining gas being mostly carbon dioxide (CO2) and saturated moisture. Hydrogen sulfide (H2S), Volatile Organic Chemicals (VOC) and siloxanes generally amount to less than 0.5% of the biogas.

Technology to satisfy California Rule 21 and Rule 30 for RNG pipleine injection. While digesters normally require only carbon dioxide (CO2) removal from the product gas, landfills generally have issues with both CO2and nitrogen (N2) in the feed gas.  Guild Associates` approach to landfill gas upgrading is flexible depending on the needs of the customer.
