Abstract:
Recycling carbon dioxide (CO2) remains a challenge for long-duration crewed missions, as carbon is an essential element to produce vital resources. This article is a review of the state-of-the-art technologies for removing and recycling metabolically produced CO2 in microgravity environments, including stations, habitats, vehicles, and suits. The study covers the breathable air requirements for astronauts, supply requirements for missions, carbon removal technologies, and synthetic and biological conversion routes from CO2 to fuels, sugars, foods, pharmaceuticals, and materials.

Forms of CO2 Transport
1. Dissolved in plasma: A small percentage (7-10%) of CO2 is transported and dissolved directly in the plasma.
2. Carbaminohemoglobin: Just over 20% of CO2 is chemically bound to...
