Process for granulating sewage sludge to give usable products, characterised in that at least one liquid and possibly other additives are added to sewage sludge, the multiple-phase system is mixed thoroughly, and the solid granules forming are separated off from the liquid phase and dried, with the condition that the liquid used is a water-absorbing solvent or solvent system for the case that the solids content in the sludge is between 0.1 and 35% by weight, or for the case that the solids content in the sludge is above 35% by weight, the liquid used is alternatively a water-insoluble solvent or solvent system without a dehydrating function. |
