  • Patent number: 11920004
    Abstract: A system for processing rubber material pre-heats the material and then applies microwave energy to process the system The system comprising a rubber material receiver for accepting the rubber material which passes the material to a pre-heating unit adapted for the rubber material passing through comprising a plurality of heating elements that heat the rubber material to between about 100 to about 350 C in an oxygen depleted atmosphere. Once pre-heated, the material is conveyed to a microwave unit adapted for receiving the pre-heated rubber material comprising microwave magnetrons, which radiate the pre-heated rubber material and external heat sources 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%.
    Type: Grant

  • Patent number: 9649613
    Abstract: A controllable, continuous-feed system and process for the reduction or depolymerization of organic materials using microwave energy in a reducing, substantially oxygen-reduced atmosphere. The microwave energy is generated by a plurality of magnetrons in a microwave tunnel. Gaseous products may be extracted from the microwave tunnel for recycling and/or analysis. A collector such as a liquid trap may be used to separately collect floating and sinking constituents of the solid products while preventing the escape of the reducing atmosphere from the system.

  • Publication number: 20040054240
    Abstract: There is provided an apparatus (2) for the reduction of organic waste (4) in which the apparatus (2) comprises a conveyor (32, 40, 128) to move the waste (4) within the apparatus (2). There is also provided a first chamber (10) comprising weighing means to determine a weight of the waste and purging means to purge the apparatus of oxygen. A second chamber (12) comprises reduction means to treat, sterilize and reduce the waste for a first period of time and a third chamber comprises cooling means to cool the reduced and sterilized waste for a second period of time. There is also provided sealing means (18, 34, 36) to seal each of the first (10), second (12) and third (14) chambers from the other chambers and from exterior of the apparatus when in use.
