A combustor having a rectangular prism structure with a burner assembly mounted inside for burning waste hydrocarbon gases with combustion air provided through flame arrestors from outside atmospheric air, the combusted hydrocarbon gas exiting through an opening on top of the structure. The combustor includes a controller for operating an igniter on the burner assembly and thermocouples for measuring the temperature of exhaust gas exiting the combustor and for measuring the skin temperature of the structure. The controller can relay the operational data and the location of the combustor to a central control center through a SCADA unit connected to a telecommunications network. The controller can also relay the volume of waste gas burned to the central control center to determine the carbon credits earned by preventing the waste gas being vented to the atmosphere.
