The number of different
items Standing Rock Sanita-
tion Service can run through
its Terminator 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 po-
sitioned 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,
whoseMcLaughlin,S.D.,businesshasonelandfill.
“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 Stand-
ing 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
fourotherstates.“Isaid,‘Wehaveamachinecalled
a Terminator that will shred practically anything.
But when it comes to tires, you have to have a spe-
cial 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 purchas-
ing 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 Min-
nesota, Montana and Wyoming. According to
Kiecker,StandingRockshredstiresdowntoabout
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
thatwecangetthroughthemachine,”Alberssays.
“Most of our customers were amazed. There were
mixed car and truck tires, and even tractor tires.
Rather than pay someone to haul away its tires,
a South Dakota landfill operation discovered
an alternative handling method that’s
revolutionized how it and others do business.

“It’scompletelyportable–that’swhat
we want,” Albers says. “If you look at it
from a transportation standpoint, haul-
ing semi-load after semi-load of tires
doesn’t makes sense. There’s tremen-
dous cost savings.”
In addition, Standing Rock’s cus-
tomers 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’rewholetires,youcannotgettheair
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.”

other use for tire shreds in their staging

“If they have a spot that doesn’t drain
well, they’re filling it in with compacted

3. 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 elec-
tricity.StandingRockstartedon thejob
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 ne-
gotiating a long-term contract now to
continue with it,” Albers says. “[Flori-
da] 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 oppor-
tunity, Albers says, because a steady
flow of material is provided to Stand-
ing 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 be-
cause large-volume opportunities seem
to keep presenting themselves. The Ter-
minator 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, espe-
cially when you run those bulky waste
items. You’re shrinking it down to a
bucket load.”
Achieving that kind of volume re-
duction 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 hydrau-
lically. 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 it-
self out,” he says. “When it reaches max
torque it reverses on its own. Every two
minutes it reverses for 10 seconds.” PP&E
