Abstract: A method of composting garbage or refuse, in particular coarse refuse such as shrubs or bushes or the like, wherein the garbage is crushed and passed to a storage location, is to be improved in that the operation of crushing the garbage is effected while it is being picked up into a transportation vehicle and the crushed refuse is fed by the vehicle directly to a rotting dump. In addition the crushed refuse is to be conveyed, preferably by centrifugal force, to a downwardly open impact chamber which is closed all around and which stands up from the storage location, in which the refuse is distributed to form a rotting layer, whereupon the chamber is raised by the height of the layer and further material is built up on the surface thereof to produce a further layer.

Abstract: A sieve drum (1) for sieving out waste or the like, in particular domestic refuse, having an intake associated with an open end of the drum is mounted pivotably at an angle or inclination (w) approximately at the middle of its length (n) and is to have perforations (14, 15) of different sizes. It has also been found advantageous for the perforations (14, 15) to be of cross-sections which decrease in a direction of the sieve drum (1) from one end thereof.

Abstract: A method and apparatus for preparing compost material on a storage surface in which a layer of material is produced from strips which are placed with their longitudinal edges adjacent one another and wherein at least one additional layer of compost material is placed on the adjacent strips. In the course of depositing the layers of compost material, hard substances are removed therefrom. The compost material is deposited by a rake-type conveyor member which is capable of being raised and lowered. An aerating device can be provided to loosen the compost material and a pressing device can be provided to produce compact units from the compost material. An aerating system including aerating lances which are movable into and from the compost material can be provided.
