Abstract: A system for processing rubber material, the system including a rubber material receiver for accepting the rubber material; a pre-heating unit adapted for the rubber material passing through comprising a plurality of heating elements that heat the rubber material to between 100 to 350 C in an oxygen depleted atmosphere; a microwave unit adapted for receiving the pre-heated rubber material comprising microwave magnetrons, which radiate the pre-heated rubber material in an oxygen depleted environment until the pre-heated rubber is substantially reduced to a carbonaceous material having a volatile content of below 5% and more preferably below 2%; a cooling conveyor that receives processed rubber material from the microwave unit and cools the material in an oxygen depleted environment; and one or more conveyors for transporting the rubber material from the rubber material receiver into and through the pre-heating unit and into and through the microwave unit to the cooling conveyor.
