Beschreibung
Zusammenfassung:	A recycling method for a direct air capture device is a recycling method for a direct air capture device (10) including a porous carrier (12) on which a carbon dioxide absorbent is supported. The porous carrier (12) 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 (12) by heating the direct air capture device (10) to a predetermined temperature, and then causing a new carbon dioxide absorbent to be supported on the porous carrier (12).
