A method for separating and sorting the material constituents and reprocessing for potential re-use and/or resale of at least a part of these constituents of cans or the like which contain substances polluting the environment and which are comminuted in a container-comminuting device which contains a working chamber, which is sealed air-tight towards the outside and has motor-driven comminution tools and is connected to a nitrogen feedline and to an exit gas line and has a lock sealed air-tight and located above the working chamber and a receiving chamber, located below the latter and sealed air-tight, for the solid and liquid constituents, is characterised in that the solid and liquid constituents are, after emerging from the comminuting device, first separated from one another and the liquid constituents are dehalogenated by the sodium process known per se and taken to disposal in the known manner, the solid constituents are fed to a liquid bath provided with a cleaning agent and the metallic parts and the plastic parts are separated from one another therein by the flotation principle, the plastic parts are then fed to a collecting vessel for further mechanical processing and the metallic parts are separated by means of magnetic separation into ferrous and non-ferrous constituents and collected in separate receiving containers, and in that finally the plastic parts and the metallic parts are taken to disposal and/or to their further use or re-use where appropriate.
