Recycling Shingles To Make Asphalt

SIOUX FALLS, SD -
A local construction company is taking roofing shingles and turning into asphalt.
Mother Nature isn't the only one benefiting from the new product.
Used shingles are getting a second lease on life thanks to Concrete Materials in Sioux Falls. This pile is quickly being turned into tiny bits that will be made into parking lot asphalt.
"We're saving oil and we're saving the natural aggregate," Concrete Materials Aggregate Division Manager Jon Mulloy said.
So far this year, the company has taken nearly 2,200 tons of shingles and turned them into asphalt. In the past, contractors would pay $30 a ton to dump the shingles into a landfill, but Concrete Materials will take them for just $10 a load.
"The incentive for us is that, we don't have to use as much virgin asphalt oil in our mix and at $400 a ton for that oil, it is a considerable cost savings for us too," Mulloy said.
The recycled shingles are then mixed with recycled asphalt from old roads that were torn up to create a completely new, greener product.
By using the old asphalt, Concrete Materials uses less natural aggregate from their quarry near Interstate 29, ultimately making it less expensive to recycle roads than to build brand new ones.
"Besides the fact that it's good for the environment it is a cost savings for the contractor and ultimately for the city and the state," Mulloy said.
And while it is a win-win for contractors and Concrete Materials, the biggest beneficiary is the environment.
The recycled shingles will be paved later this week in an engineering firm's parking lot on Russell Street.
