"We project there's over 100,000 signs in Colorado," Brent Hildebrand, vice president of recycling for Alpine Waste & Recycling, said.

In an effort to keep those plastic film and corrugated plastic signs out of landfills, Alpine started recycling them in 2007.

"Literally driving down the street looking at all the signs in yards and thinking about how long plastic lasts if it is buried in a landfill, and we said to ourselves, can we recycle these materials? And yes we can," Hildebrand said.

Following the 2008 Presidential election, 1.5 tons of unwanted election material in the Denver metro area was collected and recycled by Alpine. This year they are hoping to expand the program with the support of three communities.

Arvada, Aurora and Lone Tree have established recycling sites where residents can drop off political yard signs.

Arvada residents only can drop unwanted yard signs off in recycling bins at 6161 Old Wadsworth Blvd. between Nov. 6 and Nov. 23.

Aurora has two political yard sign recycling sites for residents and non-residents. Signs can be dropped off at the Central Facilities Center at 13646 E. Ellsworth Ave. from 8:30 a.m. to 4:30 p.m. Monday through Friday or at the Saddle Rock Golf Maintenance Center at 21705 E. Arapahoe Road from 7 a.m. to 1 p.m. Monday through Friday.

Lone Tree residents only can drop off political yard signs at the Lone Tree Municipal Building at 9220 Kimmer Drive. The recycling bin, which is located on the east side of the parking lot, can be accessed from Teddy Lane or Kimmer Drive.

Once collected, the signs will be processed at the Alpine Waste & Recycling facility in Denver.

"They come through our system here and they get bailed into cubes and then we ship those off to the end processor to make new items out of those materials," Hildebrand explained. "It can be a flower pot or a trash bag. It can be a toy, a lawn chair. It can be a bunch of different things."
