Abstract A method of safely treating medical wastes such as syringe needles, absorbent tissue and bandages, wherein all the steps of treatment from throwing medical wastes into the container to the final disposal are identified by the appearance of the container. There is also provided a disposable container that can be safely used with the method. A container according to the invention comprises a lid section provided with a certain amount of elastic filler material between an inner lid and a top lid, a pair of input ports provided on the lid section for throwing medical wastes therethrough and a pair of semi-circular rotary lids for opening and closing the input ports, wherein the input ports are provided with a larger opening and a smaller opening which is in communication with the larger opening and so dimensioned to come into engagement with the tip of a syringe so that the needle is removed from the syringe by pulling up the latter from the opening.
