Explosions could be seen from kilometres away after a fire broke out at a recycling facility in Cambridge late Tuesday night.

Around 9:15 p.m., fire crews were called to Bomet Recycling on Main Street.

Pumper trucks from Breslau, North Dumfries and Puslinch were brought in to assist the Cambridge Fire Department in battling the fire.

Witnesses told CTV News they heard multiple explosions coming from the site.

According to fire chief Neil Main, those explosions were likely caused by magnesium or some sort of metallic substance.

The fire was contained to a number of old cars, and did not spread to the building on the property – but propane tanks and other items were moved out of the building as a precaution.

After about four hours, the flames were extinguished.

No injuries were reported.

The cause of the fire remains under investigation.
