Boulder police evacuated a recycling center Wednesday morning for a hazardous materials situation.

Officers were sent to Eco-Cycle at 6400 Arapahoe Road in Boulder at 9:46 a.m. after a woman brought in an item for disposal.

The department’s hazmat team determined that the item was a U.S. military device, said Dionne Waugh, a police spokeswoman.

Authorities turned over the device to the military.
