Abstract

The invention relates to a method for treating biogenic residues, especially cafeteria leftovers, meat refuse, clarification sludge, organic industrial wastes and the like, wherein the residues are subjected to temperature pressure hydrolysis. In order to obtain a higher flow rate for residues using a small apparatus, the invention provides that temperature pressure hydrolysis is carried out in a cylindrical section in a first direction and in an external radial section in a second direction, the second direction being opposite to the first direction.
