In the process, the wet sewage sludge originating from a preceding mechanical dewatering is mixed with brown coal, brown coal coke or their mixtures in a weight ratio of sewage sludge to brown coal or its mixtures with brown coal coke of 1:3 to 3:1 and subsequently compacted wet at moderate compaction pressures above 50 bar to dimensionally stable mouldings. The briquetted mouldings can then be fed to a power station boiler as an auxiliary fuel to a thermal utilization or utilized chemically in a pyrolysis or gasification process for the production of fuel gas or synthesis gas.
