The invention proposes a closed environmental compartment to accommodate humans, e.g. a spacecraft, with a life support system (14) configured to remove metabolic carbon dioxide (CO 2 ) from its internal atmosphere, and with at least one work chamber (16), which is configured for a performance of an extraction and/or purification process with carbon dioxide (CO 2 ) as a solvent, wherein the carbon dioxide (CO 2 ) required for the extraction and/or purification process in the work chamber (16) is supplied by the life support system (14). |
