A fire broke out overnight at the Northstate Rendering Plant off Highway 99 near Oroville that destroyed hundreds of thousands of dollars worth of equipment.
Employees at the plant did not want to comment about the fire Friday morning, and CAL FIRE said they were able to get it out quickly.
Firefighters said the blaze started in a group of smaller silos that sit in the back of the plant.
CAL FIRE was called to the scene a little after 1 a.m.
The Northstate Rendering Plant takes deceased animals and uses the methane produced from burning their bodies and turns it into electricity.
CAL FIRE said they were concerned about the methane gas produced from the animals being processed.
"We didn't know how dangerous it was at first but it ended up not being dangerous as we thought,” said Battalion Chief Rob Sonstens.
CAL FIRE said the blaze did not pose a threat to any of the surrounding areas. No one was hurt during the fire.
The cause of the fire is under investigation, and total damage is estimated at $250,000.
