A method for use of a system coupled to at least one sensor and at least one flow control mechanism of a gas extraction system, the system comprising at least one controller and configured for use in connection with a landfill gas extraction process for extraction of landfill gas from a landfill via the gas extraction system, the method comprising: using the at least one controller to perform: obtaining, based on at least one measurement made by the at least one sensor, at least one current value indicative of a selected characteristic of the landfill gas extraction process, such as oxygen concentration, gas temperature, gas pressure or methane concentration, determining, at discrete time intervals, whether the at least one current value satisfies at least one compliance criterion for the selected characteristic, and when it is determined that the at least one current value does not satisfy the at least one compliance criterion for the selected characteristic, performing a corrective action.
