In accordance with "The Manual for Management of Infectious Waste" which is based on the "Waste Management Law", a counterplan for the appropriate management of medical waste must be carried out in every hospital. This requires establishing "a committee for the appropriate management of medical waste" and to assign a "responsible person for management of medical waste" (an administrator for managing industrial waste under special control) inside the hospital. Since the law requires hospitals to take responsibility for discharging medical waste, hospitals must adopt a prudent policy for waste management. It becomes a most critical issue for hospitals, because medical waste is the subject of spot inspection under the supervision of MHW, and also the subject of border transgression prohibition between countries(both import and export) by the Bazel Treaty (1989) that Japan ratified in 1993. In this study, we discuss medical waste management in the central laboratory based upon the counterplan for appropriate management of medical waste at our hospital.
