Current Activities

Permit Application Complete: On Dec. 22, 2016, Trioxy Inc. submitted a permit application to the department and U.S. Environmental Protection Agency (EPA) Region 7, to acquire a Missouri Hazardous Waste Management Facility Part I Permit for a proposed new facility. Trioxy submitted permit application revisions on Dec. 27, 2016, and Jan. 31, 2017. The department determined the permit application was complete and invites the public to review and offer written comments on the permit application while the department conducts a technical review of the permit application.

The public can review and copy the permit application and supporting documents at the Louisiana Public Library, 121 N. Third St., Louisiana, MO (during normal business hours) or the agency locations above. Comments on the permit application are more effective if they point out legal or technical issues. You may submit written comments online or by mail to Maria Bonney PE, Missouri Department of Natural Resources, 7545 S. Lindbergh Blvd., Suite 210, St. Louis, MO 63125-4839.

 

The Trioxy facility is located on about 4 acres at 3651 W. Industrial Park Drive in Louisiana, MO. Trioxy would like to operate a fully-enclosed hazardous waste and infectious waste treatment and storage facility. The new facility would be designed to manage both infectious waste and hazardous healthcare waste from hospitals, clinics, dentists and veterinarians. Trioxy would like to treat the healthcare waste and blend it with liquid hazardous waste to create fuel. The resulting hazardous waste-derived fuels would be transported to hazardous waste permitted cement kilns to be used as a substitute for coal to heat the kilns.

The healthcare waste would 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 would be injected into the shredding unit. The waste would then be sent to an enclosed treatment bin, where it would again be treated with ozone to finish sterilizing the waste. This process is similar to the technology used to disinfect drinking water.

The ozone-treated waste would then be sent to the fuel blending operation where it would 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 solvents, including spent 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 while washing reusable plastic containers in which infections waste is received. Trioxy plans to operate a hazardous waste container storage area, with a proposed capacity of 32,314 gallons.

Trioxy will receive off-site hazardous waste in bulk tanker trucks, intermodal containers and drums, and healthcare waste in bins or boxes. 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 transported off-site to the receiving permitted cement kiln.

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 proposed new facility, there have been no releases or need for remediation at this site.

Trioxy submitted a permit application on Dec. 22, 2016, to acquire the necessary hazardous waste permits to begin operating the facility.* Trioxy submitted permit application revisions on Dec. 27, 2016, and Jan. 31, 2017. The department determined the permit application was complete and approved the permit application for technical review on March 29, 2017. The department is conducting a technical review of the permit application.

*Trioxy is also pursuing a separate permit from the department’s Solid Waste Management Program for the infectious waste element of the proposed facility.
