Abstract: The waste suction and storage device includes a box (3) which, on the one hand, comprises waste storage means and at least one separation compartment (6) whose lower part is open and connects with the waste storage means and which, on the other hand, is equipped with ventilation means and includes a waste introduction opening and an air discharge opening (15).

Abstract: An aeraulic separator for automatically separating materials into three batches of different weights or shapes having a chamber under a slight depression with an inlet opening, two perforated inclined planes with an inclination of angle .alpha. and .beta.,.beta. being greater than or equal to .alpha., supplied with air under pressure, three outlet openings for the three batches, and a deflector. The heavy materials drop through the first opening adjacent the second inclined plane. The materials of intermediate weight are projected above the deflector and drop in the second opening, while the light materials are sucked through the third opening connected to a suction system. The separator is preferably mounted on a system for vibrating at low frequency and high elongation.
