ABSTRACT:
A method and apparatus for the foam-encasing of refuse, through the intermediary of which refuse being dumped may, in a simple and satisfactory enclosed manner with respect to the surroundings, be transported, stored and further processed. In the method the refuse or the like is compacted and foam-encased by an all-encompassing closed-cellular foam material layer so as to form a predetermined completely defined three-dimensional body. The apparatus for carrying out the method is constructed, in one embodiment, so as to consist of a closed form constituted of a plurality of form elements, which are adapted to be separated from each other, for the compacting and foam-encasing of the refuse or the like, and in whose walls there are distributed a plurality of nozzles for the infeed of the foam materials into the form. The apparatus for carrying out the method may also be constructed whereby at least two conically converging conveyor bands are provided for the compacting of the refuse or the like, and including a successive channel with a separating arrangement for the refuse in the inlet region, a nozzle system for the foaming sequence in the intermediate region and a separating or cutting arrangement for the foam material in the end region thereof. In another embodiment, there is provided a barrel-like container particularly adapted for transporting and storing poisonous or toxic refuse, which is encompassed by a thin layer of plastic material which, in turn, is coated by the closed-cellular foam material.
