Zusammenfassung:A recycling method for a direct air capture device is a recycling method for a direct air capture device including a porous carrier on which a carbon dioxide absorbent is supported. The porous carrier is made of an inorganic material having a hydroxyl group. The carbon dioxide absorbent is a hydrophilic polymer. The recycling method includes removing a used carbon dioxide absorbent from the porous carrier by heating the direct air capture device to a predetermined temperature, and then causing a new carbon dioxide absorbent to be supported on the porous carrier.
