Abstract:
1. A sorting system for separating solid waste including heavy fraction, mid fraction and light fraction materials of paper and light plastic film, comprising: a first conveyor belt system for moving the solid waste from a first end to a second end so that the solid waste cascades over the second end whereby the heavy fraction material falls downward to a first collection area; a first air manifold situated beneath the second end of the first conveyor belt system forming a first planar sheet of air to convey the mid fraction and light fraction materials of the solid waste to a second conveyor belt system; the second conveyor belt system for moving the mid fraction and light fraction material received from the first conveyor belt system from a third end to a fourth end of the second conveyor belt system; the fourth end of the second conveyor belt system being elevated above the third end the second conveyor belt system whereby a rollable mid fraction of the solid waste can tumble backwards to the third end of the second conveyor belt system and drop into a second collection area while the remaining mid fraction and light fraction solid waste continues to the fourth end and cascades over the fourth end whereby the mid fraction pieces of solid waste fall downward into a third collection area; and a second air manifold situated beneath the fourth end of the second conveyor belt system forming a second planar sheet of air to convey light fraction materials of the solid waste to a third conveyor belt system.
