CANON CITY, Colo. (April 24, 2000)—The Phantom landfill near Canon City has brought a new industry trend to Colorado with its use of shredded tires in the liner.
The second phase of the year-old landfill, located about 200 miles southwest of Denver, uses 3,000 cubic yards of shredded scrap tire chips to form a 10-inch drainage layer that sits on top of the clay liner. The tires are used instead of a 6-inch layer of pea gravel, landfill manager Gary Fuselier said.
"We ran tests on it and from that we found, because of compression, it would take 10 inches of tires to replace the 6 inches of gravel," Mr. Fuselier said. "After we did all the tests, we went to the state with our application to use the tires, and it took about 90 days to get everything settled."
Mr. Fuselier and landfill owner Les Liman learned about using scrap tires for drainage from landfill operations in Iowa and Texas.
"The only thing we wanted a little different was a 2-inch shred. We have the tires run through twice," Mr. Fuselier said. "The first time you get a 6-inch square, and then we run it through again.
"We used about 150,000 tires in this cell, and right now it looks like it´s going to be a big thing in Colorado."
The landfill is "taking care of two problems" according to Mr. Fuselier. He and Mr. Liman are not only getting rid of scrap tires but also providing landfill operators an alternative to spread on top of the clay liner, a process that takes about nine hours, according to Mr. Fuselier.
"The cost savings is really unbelievable. It´s a 75-percent savings over gravel," he said.
The Colorado Department of Public Health and Environment´s approval of shredded tires for the drainage layer means the material probably will turn up in future landfills and become the industry standard in the state, said David Douglass, a senior engineer for KRW Consulting Inc., in the Denver suburb of Lakewood. KRW has designed more than 15 landfills in Colorado.
Mr. Liman said he plans to use the shreds in another landfill he owns in Summit County, which is home to the ski resorts of Keystone and Breckenridge.
