摘要： The invention relates to a process and a device for processing of biological residual material, in particular sludge. The process according to the invention is characterised by the following procedural steps: de-watered sludge is dried in a fluidised bed dryer until a maximum water content of 10 % is obtained; the dried sludge is gasified in a fluidised bed gasifier subject to a lack of oxygen thereby producing product gas; a block-type thermal power station is operated using the product gas; the waste heat from the fluidised bed gasifier and the block-type thermal power station is supplied to the fluidised bed drier or the fluidised bed gasifier by closed pipe systems. The device according to the invention comprises a fluidised bed drier, a fluidised bed gasifier and a block-type thermal power station, a de-watering device generally being connected upstream of the fluidised bed drier.
