In a process for the treatment of dust or the like containing organic constituents, in particular filter dust from foundry sands containing binding agent, the dust is introduced into a fluidizable heat carrier of refractory material, heated and burnt, wherein the heat carrier is preferably preheated to receive the dust. An apparatus for carrying out that process, a loose material bed comprising a fluidizable refractory material is arranged as a heat carrier in a combustion chamber of a furnace on a fluidization plate, and provided in the heat carrier are a heating means and at least one feed means for the dust.
