Organic waste materials are mixed and batches are separately brought into the form of a coherent substantially homogeneous pulp with a moisture content between 50 and 55% by weight, by heating with exhaust gases, drying in an oven, admixing dry material, and spraying dry material with liquid manure recuperated from the waste materials. The pulp is chopped and immediately thereafter extruded to form frangible strands, sections of which are allowed to break off, without cutting, and to further break by dropping onto a conveyor. Breakage into pellets is completed, without the use of a conventional pelletizing drum involving compression of the pellets, in a vibrated fluidized bed where the pellets are superficially dried to a non-tacky state, drying being completed in further non-vibrated fluidized beds.
