Abstract: An apparatus for stunning an animal with an exhaust gas mixture includes a stunning chamber located at a processing site to contain therein as many an animal selected to be stunned; and a combustion chamber located at the processing site for combusting a mixture to provide therefrom an exhaust gas mixture which includes carbon dioxide for stunning the animal in the stunning chamber.

Abstract: An apparatus for producing heat and reducing emissions with an exhaust gas mixture at an industrial facility is provided, which consists of a CO2 generation chamber (61) located on-site at the industrial facility (110), the CO2 generation chamber adapted to generate an exhaust gas mixture (57) comprising gaseous carbon dioxide; a production chamber (112) located on-site at the industrial facility, the production chamber constructed and arranged to receive therein gaseous carbon dioxide and as many a product selected to be processed with the gaseous carbon dioxide at the industrial facility; and a first pipeline (74) interconnecting the CO2 generation chamber with the production chamber for delivering at least a portion of the exhaust gas mixture comprising the gaseous carbon dioxide from the CO2 generation chamber to the production chamber without the portion being vented directly to atmosphere. A related method and exhaust gas mixture is also provided.
