By regulations, combustible infectious medical wastes must be incinerated; and incombustible ones, sterilized before transportation. Most of the hospitals treat the medical wastes by the depatment of general affairs and they pay more money for combustible infectious medical wastes reather than incombustible ones. In our study, we found most of the hospitals treat the medical wastes by incineration or santiary land filled after incineration. Hospitals will attend the common incinerating facilities for medical wastes by medical care region with the support of the regional medical network coordination committees or the public hospitals for the common disposal of the second category wastes in the region to treat the medical wastes. In our conclusion, we suggest that the EPA add the amount of the public or the private hospitals for the common disposal of the second category wastes in the region to treat the medical wastes, and to reduce the cost of the treatment of the medical waste for hospitals.
