The number of different items Standing Rock Sanitation Service can run through its Terminator

South Dakota-based Standing Rock Sanitation Service’s tire-shredding abilities drew the attention of a Florida waste energy plant, for which Standing Rock is shredding tires, railroad ties and wood waste.

6000S shredders is seemingly endless, says Rhett Albers, project engineer and manager. But one particular item, tires, changed the nature of Standing Rock’s business and positioned the company to reach new heights with its shredders.

“For the longest time we were trying to figure out how to deal with waste tires,” says Albers, whose McLaughlin, S.D., business has one landfill. “It was so expensive to deal with them because of our location. We had to ship them out.”

Albers estimates Standing Rock previously paid about $250 per ton for tires to be hauled away from his facility. The spend was difficult to justify, he says, because the revenue Standing Rock generated from receiving and handling tires in the first place was barely more than the company’s expense.

So, Albers sought out other methods to make tire handling more lucrative.

“About a year and a half ago Rhett asked how our machine would work shredding tires,” says Brad Kiecker, sales manager at Midwest Recon, a Komptech dealer that covers South Dakota and four other states. “I said, ‘We have a machine called a Terminator that will shred practically anything. But when it comes to tires, you have to have a special shredding drum.’”

Building a business
Still, as capable as Komptech’s Terminator 6000S is, Standing Rock alone didn’t have the volume necessary at its own facility to justify purchasing a unit. Albers realized a major opportunity was available when he considered how landfills like his in North and South Dakota likely faced some of the same tire handling challenges as his facility.

“We thought if we could stockpile our tires, other facilities could stockpile theirs and we could establish a route to collect tires,” Albers says.

Now, Standing Rock shreds tires for facilities across North and South Dakota and parts of

Minnesota, Montana and Wyoming. According to Kiecker, Standing Rock shreds tires down to about a 6- or 8-in. product. In an hour, he estimates the company can grind 1,500 car tires.
“It’s been a lot higher volume than we expected that we can get through the machine,” Albers says. “Most of our customers were amazed. There were mixed car and truck tires, and even tractor tires. We’re averaging 12 to 15 tons per hour. When we go around, some of these places have 300 to 500 tons for us to shred when we pick them up.”

Standing Rock doesn’t just pick up tires, though. The company often shreds tires off site, hauling its Terminator from facility to facility.

“It’s completely portable – that’s what we want,” Albers says. “If you look at it from a transportation standpoint, hauling semi-load after semi-load of tires doesn’t makes sense. There’s tremendous cost savings.”

In addition, Standing Rock’s customers get to realize the benefits of tire shreds in their own landfills.

“They realize they can landfill them as a worst-case scenario,” Albers says. “If they’re whole tires, you cannot get the air gas or air pockets out of them. The tires will just keep moving up the landfill.”

In addition to landfilling them, Albers says landfill operators can use tire shreds as base material for their facility, as an alternative daily cover to improve litter control, as a means to control erosion and as a base for pipe bedding.

“Tire shreds protect the pipe for methane,” he says. “Landfills, as they accumulate waste, generate methane gas. The bigger landfills are collecting that methane gas and then selling it for energy purposes.”

Landfill operators have found yet another use for tire shreds in their staging areas.
“If they have a spot that doesn’t drain well, they’re filling it in with compacted tire shreds and filling it in with rock over that,” Albers says.

Venturing out
Word of the company’s tire-shredding abilities got around last winter, as a Florida waste energy plant reached out to Standing Rock asking it to put together a test program to shred tires, railroad ties and miscellaneous wood waste that can be blended to create electricity. Standing Rock started on the job in February near Lakeland, Fla., buying a second Terminator 6000S to handle the workload.

The original plan was to spend three or four weeks in Florida, but Standing Rock is still there because the waste energy plant wants the Terminator to process material every day.
“This has gone so well that we’re negotiating a long-term contract now to continue with it,” Albers says. “[Florida] is a little farther than we anticipated entrenching ourselves, but if there’s an opportunity we’re going to try to make it work.”

The job in Florida is a good opportunity, Albers says, because a steady flow of material is provided to Standing Rock.

“We’re running seven days a week,” he says. “It’s so much different than our area up north. Since we’ve been in Florida, we’ve had a lot of people come in wanting to see what we’re doing. We have made a lot of adjustments with the teeth and setup of the machine to get a higher volume and a better tire shred. We were amazed nobody is doing the kind of volume with tire shreds we are.”

Eventually, Albers sees Standing Rock purchasing a third shredder because large-volume opportunities seem to keep presenting themselves. The Terminator 6000S’s versatility makes it a candidate yet again for Standing Rock’s tire-shredding business.

“We’ve tried just about anything you’d expect to bind or tie up in the machine, and it doesn’t,” he says. “The volume reduction is unbelievable, especially when you run those bulky waste items. You’re shrinking it down to a bucket load.”

Achieving that kind of volume reduction while avoiding machine jams is key, as well.

“If we get a large chunk of solid iron or steel in it, it will shut down and you can just open up the entire machine hydraulically and drop it out,” Albers says. “The hydraulic cylinder lifts the counter cone against the stationary drum that turns. You lift that hydraulically. It takes a few minutes, and it drops out whatever is in there.”

The drum on Standing Rock’s units is somewhat unique, Kiecker adds.
“Stuff won’t wrap around it because it automatically reverses and cleans itself out,” he says. “When it reaches max torque it reverses on its own. Every two minutes it reverses for 10 seconds.”
