HENRY, TN — The fire at the Sigma Renew 360 facility in Henry was officially declared extinguished on Saturday at approximately 11:00 a.m., following an extended response effort lasting nearly 24 hours. The cause of the fire remains under investigation by the Henry Fire Department and State Fire Investigators. A formal incident report, including the determined origin and cause, is expected to be released in the coming days.
Two minor injuries were reported during the incident. According to the Henry Fire Department, two firefighters experienced heat exhaustion. Both individuals were treated on scene, released, and returned to duty.
Upon conclusion of active firefighting operations Saturday morning, the site was transitioned to Ozone Environmental Services, Inc. for water runoff containment and environmental remediation.
Sigma Renew 360 Plant Manager Loriane Dodd advised incident command that the company is fully committed to proper cleanup and recovery efforts. Ozone Environmental has been contracted to conduct ongoing water testing, mitigation, and remediation of the facility, as well as surrounding properties and nearby streams.
The facility processed low-density polyethylene (LDPE) into pellets for manufacturing use. No additional chemicals were reported to be present.
Due to the high fuel load and structural collapse, the fire burned intensely for approximately 24 hours. Firefighters, local contractors, and the State Division of Forestry worked continuously to extinguish the fire.
EMA issued an air quality advisory for the Town of Henry and surrounding areas. Residents with respiratory sensitivities were advised to remain indoors. Henry School followed guidance to keep students indoors and safely dismissed at the normal time.
EMA Director Ron Watkins met with local officials and response partners to coordinate recovery efforts.
Response measures include runoff containment, water removal, absorbent deployment, and environmental monitoring.
On Sunday morning, the fire briefly rekindled and was quickly extinguished. Fire personnel will remain on site for several days as a precaution.
The Tennessee Department of Environment and Conservation is expected to be on scene Monday morning to assess potential environmental concerns.
