<p>A process is proposed for disposing of aqueous waste liquids from hardboard manufacture, the waste liquids being thickened prior to their combustion, having the characteristic that at least one magnesium compound and at least one inorganic acid are mixed into the waste liquid, in particular the thickened waste liquid, to be burnt, and the waste liquid is then burnt at temperatures of above 850 degree C, preferably above 950 degree C, in a fluidized bed having a fluidized bed material comprising up to 30% of dolomite having a mean particle size of 1-3 mm.</p> |
