David Scheeres has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10780620
    Abstract: The present invention is an apparatus and method for volumetric reduction of polymeric material and in particular synthetic polymeric textile materials. Such materials are typically used in hospital operating rooms and have material memory meaning that they re-expand after compression. Consequently they are difficult to process as waste material. The present invention is a method and apparatus for thermally compacting a polymer comprising a first and second heated surface inclined downwardly towards each other and providing with a passage at their lower ends through which melted polymeric material may pass.
    Type: Grant

  • Patent number: 9956736
    Abstract: The present invention relates to an apparatus and method for processing of waste and in particular processing involving a volumetric reduction of waste materials. There is an apparatus for processing waste material comprising a compaction compartment for receipt of waste material, the compaction compartment have a screw vane for processing waste material through the compaction compartment and a waste material outlet. In one aspect the apparatus comprises a heating zone including an arrangement for heating the waste material received from the waste outlet, the apparatus further comprising a cooling zone including a cooling arrangement for cooling the waste material received from the heating zone.

  • Publication number: 20140308161
    Abstract: Embodiments of system and method of sanitizing medical waste are described. In one embodiment, there is a the method including, introducing the medical waste into a heating zone, heating the medical waste to a sanitizing temperature thereby melting a majority of the medial waste, moving the medical waste via gravity into a cooling receiver, cooling the medical waste by cooling the cooling receiver; and removing the medical waste from the cooling receiver.
