Current Activities

Final Permit Issued: On May 11, 2018, the department issued a final Missouri Hazardous Waste Management Facility Part I Permit for the Trioxy Inc. facility, effective immediately. The U.S. Environmental Protection Agency (EPA) decided not to issue a Hazardous and Solid Waste Amendments Part II Permit, since EPA has no specific regulatory conditions for the facility beyond those contained in the final Part I Permit and Missouri is fully authorized for all permitting and contingent corrective action activities.

This is a new commercial infectious and hazardous waste treatment and storage facility. Trioxy is operating the infectious waste treatment component of the project under a permit issued by the department’s Solid Waste Management Program. After a thorough technical review of the permit application and opportunity for public comment, the department issued a final Part I Permit, which allows Trioxy to operate the commercial hazardous waste storage and treatment component of the project.

Any parties adversely affected or aggrieved by the department’s decision to issue the final Part I Permit, or specific conditions of the final Part I Permit, may be entitled to pursue an appeal before the Administrative Hearing Commission by filing a written petition by June 11, 2018, as more fully described on page 5 of the final Part I Permit. The public can review and copy paper copies of the final Part I Permit, summary and response to comments received during the public comment period and supporting documents at the Louisiana Public Library, 121 N. Third St., Louisiana, Mo. (during normal business hours) or the agency locations above.


The Trioxy facility is located on about 4 acres at 3651 W. Industrial Park Drive in Louisiana, Mo. The property was previously used for agricultural purposes, mainly to grow corn. Trioxy purchased the property in 2017, to operate a fully-enclosed commercial hazardous waste and infectious waste treatment and storage facility at the site. The new facility is designed to manage both infectious waste and hazardous healthcare waste from hospitals, clinics, dentists and veterinarians. Trioxy will treat healthcare wastes and blend it with liquid hazardous waste to create hazardous waste-derived fuels. The healthcare waste will be initially treated in an ozone disinfection/shredder unit. Once all pieces of solid waste are reduced to a size suitable for treatment, a high concentration of ozone gas will be injected into the shredding unit. The waste will then be sent to an enclosed treatment bin, where it will again be treated with ozone to finish the sterilization process. This process is similar to the technology used to disinfect drinking water.

The ozone-treated waste will then be sent to the fuel blending operation where it will be blended with liquid hazardous waste to achieve the desired fuel characteristics, such as BTU value and metals and chlorine content. The liquid hazardous waste will be a mixture of alcohols and spent solvents, including ethanol, methanol, isopropyl alcohol, benzene, toluene, xylene, furniture stripper, acetone and a variety of other chemicals. Most of the hazardous waste will come from off-site permitted hazardous waste facilities that collect these wastes. Trioxy will also use water-based spent solvent they produce from washing reusable plastic containers in which infections waste is received. Trioxy will receive healthcare waste in bins or boxes and off-site hazardous waste in bulk tanker trucks, intermodal containers and drums. Trioxy is permitted to operate two hazardous waste container storage areas, with a combined maximum volume of 50,314 gallons.

The liquid hazardous waste will be pumped into the fuel blending unit, blended with the ozone-treated waste and pumped to an outgoing tanker truck. Once the process is complete, the hazardous waste-derived fuel will be shipped off-site to the receiving permitted hazardous waste facilities to be used as a substitute for fossil fuels.

According to applicable state and federal hazardous waste laws and regulations, all hazardous waste treatment, storage and disposal facilities are required to investigate and clean up releases of hazardous waste and hazardous constituents to the environment at their facility resulting from present and past hazardous waste handling practices. Because this is a new facility, there have been no releases or need for remediation at this site. However, the department did worked with Trioxy during the permit application process to ensure no pre-existing contaminated areas were located on property slated for permitting their operations.

Trioxy is currently operating a commercial hazardous waste storage and treatment facility at the site under a department-issued Missouri Hazardous Waste Management Facility Part I Permit, issued May 11, 2018.* The regulated units under the permit consist of two hazardous waste container storage areas.

*Trioxy obtained a separate permit from the department’s Solid Waste Management Program for the infectious waste treatment component of the project.
