A large fire tore through a trash transfer facility in the far East Valley late Sunday night, sending flames into the sky near State Route 24 and Signal Butte Road in Mesa. No injuries were reported in connection with the blaze, which drew a heavy emergency response to the fast-growing corridor on the city's eastern edge.
The incident was first detailed by FOX 10 Phoenix, whose reporter Irene Snyder covered the response at the waste facility as crews worked to knock down the flames. The fire broke out Sunday night at the trash transfer site near SR 24 and Signal Butte Road, according to the station's report, and no one was hurt.
A Growing Corridor Meets an Aging Risk
The blaze struck close to Mesa Fire Station 219, located at 3361 South Signal Butte Road, per the City of Mesa.
A Regional Pattern of Waste Fires
Waste facility fires have become a recurring headache across the East Valley. In August, Scottsdale hazmat crews were dispatched to monitor a fire involving a lithium-ion battery at Scottsdale's solid waste transfer facility near Loop 101 and Hayden Road, as reported by the Daily Independent. Lithium-ion batteries can pose fire risks at solid-waste facilities.
Mesa has grappled with this problem before. City officials reported in 2022 that improper household hazardous waste disposal caused at least three separate garbage truck fires over a multi-week span, creating safety risks for drivers and nearby homes, according to 12News. Officials at the time pointed to items like pool chemicals and aerosol cans, which can combust when compressed inside waste trucks.
State Rules and Local Disposal Options
The Arizona Department of Environmental Quality provides information on household hazardous-waste disposal.
To help residents comply, the City of Mesa operates a dedicated Household Hazardous Materials facility at 2412 North Center Street, offering free drive-thru disposal designed to keep flammable chemicals and batteries out of solid waste facilities altogether, according to National Doorstep Pickup.
Building Boom Along SR 24
The area surrounding Sunday's fire is in the middle of a major transformation. In October 2025, the Arizona Department of Transportation finalized design plans to expand State Route 24 between Loop 202 and Ironwood Drive, including new bridges and interchanges at Signal Butte Road, according to SanTanValley.com.
That construction is part of a broader transformation in the East Mesa corridor. As more homes, roads, and businesses rise around Signal Butte Road, incidents like Sunday's fire carry greater visibility for a population that has grown substantially in recent years.
