Crews put out a fire at a Hamilton composting plant after a pile of household food waste burst into flames on Sunday morning. 

At 10:42 a.m., dispatchers received a call about a fire at the city’s Central Composting Facility at 1579 Burlington St. E, said Hamilton Fire Department spokesman Claudio Mostacci.

He said a pile of “non-toxic” household food waste caught fire inside the plant. By 11:03 a.m., firefighters had put out the flames, but they continued to work to make sure the pile wouldn’t re-ignite, he said. 

The fire caused “heavy-to-moderate” smoke, but didn’t damage the building’s structure, said Mostacci.

Investigators haven't determined the cause of the Sunday morning fire. 

No one was injured in the incident.
