The present invention provides a system for processing VOC passing through a pipe structure. The pipe structure includes one or more stackable sections for heating decomposition of VOC molecules in the exhaust that passes through the sections and a self-powered cap assembly coupled to the outlet end of the pipe structure. The cap assembly includes a wind turbine mechanically coupled to a generator that supplies electricity to an electronic assembly and to the electrothermal converter in each of the heat decomposition sections. The heat decomposition section includes a paraboloidal heating dish which is coaxially fixed in a cylindric structure with its opening end facing the cap assembly. The electrothermal converter is placed in the focus of the paraboloidal dish. The exhaust gas that passes through the heating decomposition section rotates the turbine that further drives the generator through a shaft. The electricity from the generator activates the electrothermal converter that converts electrical energy into heat energy. The paraboloidal dish reflects the heat from the converter forward into the internal space of cylindric structure. The VOC molecules are decomposed under the high temperature within the cylinder. The system also includes an electronic detecting device and a wireless interface that transmits the VOC data collected by the detecting device to a computer.
