NR 526.11 NR 526.11 Treatment methods. Except as provided in s. NR 526.04, no person may dispose of infectious waste in a solid waste disposal facility unless the infectious waste has undergone treatment in accordance with this section. The treatment method shall effectively render the waste non-infectious. The treatment method shall be chosen by considering the properties of the waste being treated and the degree of microbial contamination.

NR 526.11 Note Note: The treatment method may also need to comply with air standards for control of hazardous pollutants in ch. NR 445 and with state or federal regulations for wastewater and occupational health and safety.

NR 526.11(1) (1) Methods. Except as provided in s. NR 526.04, all infectious waste shall be treated by one or more of the following infectious waste treatment methods:

NR 526.11(1)(a) (a) Incineration. Treatment by incineration shall consist of incineration in a controlled air, multi-chambered incinerator which provides complete combustion of the waste to carbonized or mineralized ash. The incinerator shall be one that is regulated by the department under s. NR 502.09 or 502.13.

NR 526.11(1)(b) (b) Steam disinfection. Treatment by steam disinfection, including but not limited to autoclaving, shall subject all the waste to a combination of operational temperature, pressure (if applicable) and time proven to render the waste non-infectious at the design capacity of the installed equipment.

NR 526.11(1)(c) (c) Chemical disinfection. Treatment by chemical disinfection shall expose the infectious waste to an appropriate type and concentration of disinfectant for a period of time sufficient to render the waste non-infectious. The chemical disinfectant shall be chosen based on the manufacturer’s recommended use of the disinfectant, the cleanliness of the surface of the waste, the contact time, the physical and chemical properties of the waste, the concentration of the disinfectant and the degree of microbial contamination.

NR 526.11(1)(d) (d) Mechanical grinding and chemical disinfection. Treatment by mechanical grinding and chemical disinfection shall expose all of the waste to the chemical disinfectant for a period of time sufficient to render the waste non-infectious. The chemical disinfectant shall be chosen based on the use of the disinfectant in medical situations, the cleanliness of the surface of the waste, the contact time, the physical and chemical properties of the waste, the concentration of the disinfectant and the degree of microbial contamination. Treatment by mechanical grinding and chemical disinfection shall prevent the release of infectious liquid or infectious gaseous discharges into the environment.

NR 526.11(1)(e) (e) Mechanical grinding and heat disinfection. Treatment by mechanical grinding and heat disinfection, including but not limited to low frequency wave radiation and microwave radiation, shall expose all of the waste to heat for a period of time sufficient to render the waste non-infectious. Treatment by mechanical grinding and heat disinfection shall prevent the release of infectious liquid or infectious gaseous discharges into the environment.

NR 526.11(1)(f) (f) Gas disinfection. Treatment by gas disinfection shall allow gas to penetrate all the infectious waste and shall render the waste non-infectious. The unit shall be operated in a manner that does not pose an occupational risk of exposure to the gas.

NR 526.11 Note Note: For ethylene oxide sterilizers, refer to OSHA regulations in 29 CFR 1910.1047. Air toxic rules in ch. NR 445 may also apply.

NR 526.11(1)(g) (g) Other methods. Treatment by other treatment methods and processes shall render the waste non-infectious and shall be appropriate with respect to all of the following: the properties of the waste being disinfected, the manufacturer’s recommended use of the disinfectant, the cleanliness of the surface of the waste, the contact time, the physical properties of the waste, the concentration of the disinfectant and the degree of microbial contamination.

NR 526.11(2) (2) Special considerations. No person may treat the following categories of infectious waste except as follows:
