A processing apparatus is powered by an internal combustion engine. Airborne emissions that are separate from the exhaust of the internal combustion engine are produced during processing. An air feedback mechanism directs the airborne emissions produced during processing to the air intake of the internal combustion engine, resulting in the emissions being combusted within a combustion area in the internal combustion engine. By combusting the emissions, the harmful level of emissions is reduced.
