The present invention provides a system for treating a granular organic material with ozone comprises: a processing vessel having an upper end and an opposed lower end, in which the vessel comprises an inlet located at or adjacent the upper end of the vessel. The inlet is configured to supply material from a delivery system to the vessel, and an outlet located at or adjacent the lower end of the vessel. At least one baffle is provided within the vessel, the at least one baffle directs the passage of the material falling from the inlet towards at least one rotating ozone injector. A pressurised supply of ozone gas is configured to pass through the one rotating ozone injector to treat the material with ozone. A separate retrofit system, with its own drive means, is also described in which at least one rotating ozone injector is supported in a hollow housing...
