Abstract: A method for the elimination of carbon dioxide from waste gases includes the following steps. First, waste gases, which include carbon dioxide, are provided from a source for waste gases. Next, the waste gases are contacted with an absorbent composition that includes perfluorodecalin solution. The waste gases, especially the carbon dioxide, are then absorbed by the absorbent composition. The absorbent composition thereby absorbs the waste gases to eliminate the carbon dioxide.
