A nearly two-day battle with flames at a rubber recycling business north of Saskatoon is finally dwindling.

The fire at Shercom Industries is nearly extinguished and most firefighters are packing up and returning to their halls. A few crews are still on scene, keeping an eye on hot spots.

“We’re having some small localized flare-ups — not a problem whatsoever,” assistant fire chief Dave Bykowy said late Wednesday afternoon. “We have basically one engine on site.”

The blaze broke out Monday evening and left heavy smoke shooting from the site well into Tuesday.

Two of the three buildings at the business were destroyed.

One building held about 20,000 pounds of shredded rubber and 80 barrels of polyurethane.

Fire crews, who worked around the clock alongside teams from Warman and Martensville, aimed to keep the barrels intact during the fight. Bykowy said the effort was to limit environmental damage and health hazards.

The building that was saved houses Shercom’s offices and some of the manufacturing processes. Crews managed to retrieve some of the company’s critical computer equipment from the building, according to Bykowy.

Bykowy said the next step is for fire investigators to comb the scene to pinpoint what started the massive blaze.

An investigation will likely begin Thursday.
