Apparatus for concentrating and sorting solid waste materials, comprising:

• a revolving screen, said revolving screen having an intake zone, a central zone and an outlet zone, said central zone comprising a cylindrical member having apertures of a size permitting common glass container objects to pass therethrough and said outlet zone comprising a plurality of parallel bars arranged in a squirrel cage fashion and having a spacing between adjacent bars of the same order of magnitude as the size of said apertures in said central zone, and having a length substantially longer than the size of said apertures;
• at least one lifting device disposed in said central zone and extending substantially from near said intake zone to near said outlet zone, said lifting device having a bevelled longitudinal profile decreasing in height towards said intake end;
• a shock absorbing lining covering said lifting device at least over a portion thereof near said intake end;
• means for rotating said revolving screen;
• and
• an extractor for collecting flexible products, said extractor comprising an endless conveyor member rotatable between two wheels, at least a portion of said endless conveyor member extending longitudinally through said revolving screen.
