Abstract: A compact apparatus for processing disposable containers at their collecting site uses a single pair of counter-rotating crushing rollers mounted one above the other. The containers are dropped against the upper surface of an indented feeding roller parallel and adjacent to the lower crushing roller. The cans are caught by a the peripheral indentations of the feeding rollers and horizontally kicked between the merging surfaces of the crushing rollers. An indented take-up roller on the opposite side of the lowest crushing roller catches the crushed containers and propels them obliquely upwards into a collecting bin.
