Abstract
Abstract A waste management system, including, a module forming a hollow cover having an open base and with the module including a passageway for receiving medical waste from the exterior to the interior. A disposable container is received within the open base of the module to have the container enclosed by the module. The module is locked in position on a wall mount which fully encloses the disposable container. A key plate is provided for disposition between the locking wall mount and the module to unlock the module from the wall mount and with the key plate locked across the open base of the module in substitution of the wall mount. A cart houses a large waste box and includes an opening into the interior of the cart for providing access to the waste box. The cart includes a cover structure disposed around the opening in the cart and with the cover structure including a cover plate over the opening. The cover structure provides a release of the key plate to allow the cover plate to simultaneously move the key plate away from the opening in the cart while extracting the key plate so as to have the disposable container fall through the opening in the cart into the waste box.
