A system for disposing of medical waste is generally configured to sort waste items into a plurality of containers according to applicable rules and regulations governing the handling and/or disposal of such items. In some embodiments, a system comprises sorting stations each of which houses a number of disposable containers. Each station can identify an item of waste, determine the most appropriate container for the item, and facilitate disposal of the item in the appropriate container. In some embodiments, a detection system for determining a presence and/or a quantity of waste items within a container is also provided. In some embodiments, access to discarded waste items is restricted once the waste items have been placed in a container.
