Apparatus for the treatment of animal excrement material, particularly liquid manure and sewage sludges, in which the material containing a high percentage of liquid is mixed with a dry additive, preferably the re-circulated dry material, and after forming into briquettes which can be heaped is ripened in heaps penetrable by air, in which for the ripening process briquettes are employed having a volume predominantly between 30 and 50 cm3. The briquettes are conveniently formed in a worm press to have a diameter of between 30 and 40 mm. and a length of between 40 and 80 mm. For a larger diameter briquette, provision is made to form a hole in the briquette. The method is performed by using an extrusion press having a moulding die having at least two sections separated by a slit there being, in each case, hole sections extending outward from the slit and opposite to each other, said sections forming the die channel, the inputs to the slits and to the hole sections having an input angle less than 45 DEG to the axis of the hole.
