Abstract

A method for cleaning waste gases containing ozone-depleting and/or climate-active halogenated compounds has a sorption device (S1,S2) having two chambers (1, 2) each containing a solid stationary sorbent (6, 7) for the ozone-depleting and/or climate-active halogenated compounds and communicate with each other via a heating device (4). The two chambers (1, 2) are alternatively connectable with the gas feeding means (8) for the waste gas to be cleaned for reversing the direction of flow of the waste gas to be cleaned.
