    Patent number: 4953457
    Abstract: A method and apparatus for treating biodegradable solid urban waste materials and selecting those non biodegradable components for recycling comprises a tunnel (1) made of steel defining an inner room or ambient of parallelepiped shape, having a rear hinge door (4) associated with adjustable counterbalance weight (5). Near the door (4) blade kneading devices (6) can be installed. In the last portion of the bottom wall of the tunnel (1) holes (7) are arranged, positioned just over a channel (3) connected to a recovering tank (22) of the percolate. At the other front end of the tunnel a moving wall (9) is mounted, capable of being moved to and fro along two rails (10) by means of hydraulic jacks (12). In the center of the wall (9) a hydraulic cylinder (31, 31a, 31b) is anchored, the piston rod (31a) which enters into the iner chamber of the tunnel (1) for compressing the waste mass. Near the upper wall (32) of the tunnel (1), there is a circulating forced air pre-chamber (13) having a grating structure.
