SAN JOSE -- Stubbornly smoldering piles of paper and cardboard at a recycling plant threatened to keep firefighters camped overnight at the site next to Municipal Stadium, after a three-alarm blaze spread throughout the facility shortly after 6 p.m. Thursday.

No injuries were reported, and the plant at South 10th Street and East Alma Avenue had been closed for about an hour when crews were called to the scene, said San Jose fire Capt. Rob Brown. Arriving firefighters found a smoky blaze that had spread throughout the facility.

"There was loose paper, paper and cardboard bundled into bails, recycling materials in all phases of storage," Brown said. "Once that stuff catches, these types of fires can be really difficult to get fully extinguished."

He added that the fire moved quickly throughout the facility because of hot temperatures, wind and dry paper.

Around 9 p.m., as ladder trucks continued to douse the facility from high above, Brown said they planned to have a couple of companies at the scene through the night.
