Abstract
Techniques are provided for controlling extraction of landfill gas from a landfill. The techniques include obtaining a measurement of concentrations of oxygen, carbon, and methane in a sample of landfill gas. At least one processor may be used to determine based on the measurement of the concentration of oxygen in the sample, the measurement of the concentration of methane in the sample, and the measurement of the concentration of carbon dioxide in the sample, a balance gas concentration in the sample. Further, the at least one processor may be used to determine whether the determined balance gas concentration in the sample is greater than a balance gas concentration threshold. Responsive to determining that the determined balance gas concentration in the sample is greater than the balance gas concentration threshold, an actuator controls the flow control mechanism to decrease the flow rate of the landfill gas being extracted from the landfill.
