'''Exhaust''' is a polluting byproduct of many high-temperature processes. This includes all furnaces, all [[Boiler (Coal)]] recipes, most [[Boiler (Gas)]] recipes and a few other buildings.

'''Exhaust''' is a polluting byproduct of many high-temperature processes, including all furnaces, all [[Boiler (Coal)]] recipes, most [[Boiler (Gas)]] recipes and a few other buildings. When released via a [[Smoke Stack]] or [[Smoke Stack (Large)]], each unit of Exhaust produces 0.5 points of [[Air Pollution]]. The [[Exhaust Scrubber]] ameliorates this pollution and produces potentially useful {{infoicon|Sulfur}}, {{infoicon|Carbon Dioxide}} and {{infoicon|Steam Lo}} byproducts. However, the [[Exhaust Scrubber]] still emits 0.133 points of [[Air Pollution]] per unit of Exhaust; thus, no factory can completely eliminate [[Air Pollution]].
Common method of disipation is to release via a {{Variants|Smoke Stack}}. This way, each unit of Exhaust produces 0.5 points of [[Air Pollution]]. An alternative method, which becomes available in the midgame, is to recycle using [[Exhaust Scrubber]].
