  • Publication number: 20240066163
    Abstract: Waste processing chamber operates in a loading mode, a processing mode and an unloading mode. In the processing mode, an environment inside the processing chamber disinfects particles of medical waste using ozone. The processing chamber includes an inlet to receive the particles. In the processing mode and unloading mode a hermetic seal is provided between the environment inside and an environment outside of the processing chamber. An outlet extracts the particles from the processing chamber and provides a hermetic seal between the environment inside and the environment outside of the processing chamber. A particle transporting arrangement stirs the particles to move the particles to the outlet for extraction. Sensors measure characteristics of the sealed environment inside the processing chamber. The processing chamber is fluidly coupled to or includes a generator to generate ozone and to maintain a target concentration level of ozone of the environment inside the processing chamber.
