Chances are good you’ve
seen the bold, bronze letters of
CARUS over the entrance to
the brick office building across
from the old Westclox plant in
Peru. You’re most likely aware
of the manufacturing facility
tucked behind the historic
Hegeler Carus Mansion in
La Salle. If you’ve raised
children in the last 20 years,
they probably learned a thing
or two about science from
a Carus-sponsored camp or
chemistry demonstration, and
if you have family in the area,
it’s a safe bet someone you
are related to has worked for
Carus Corporation at some
point. But what else do you
know about this century-old
company that’s been a major
employer in the Illinois Valley
for generations?
Did you know that within
Carus’ La Salle facility
chemists are researching
innovative new ways to clean
up polluted land, treat water
to make it safe for drinking,
and remove toxins from the
air? Did you know that the
products made locally by
your friends, relatives, and
neighbors who work for Carus
are shipped all over the world
to be used in rescue masks,
municipal water systems,
and in industries as diverse
as electronics, mining, and
fashion? Did you know that
Carus has seven locations in
the United States and Europe,
and employs roughly
400 people?
What Carus does for
customers can most easily
be summed up with the
company’s vision statement:
Bringing together customers,
employees, and specialty
chemistries to create
innovative solutions. The
following pages will give you
an inside look at Carus’ role in
the Illinois Valley, its hundred-
year history, and at the ways
the company is shaping its
next hundred years.
Carus Corporation turns 100
How much do you know about the company that’s called your community home for the last century?

1915-2015
Founded 100 years ago in
La Salle, Carus is the world
leader in permanganate,
manganese, oxidation,
catalyst, and blended
phosphate technologies.
Thousands of cities use Carus
products to provide clean
drinking water to residents.
Carus has enjoyed a century
of growth and success right
here in the Illinois Valley.
Here’s an overview of Carus’
first 100 years:
1915 - Two years before the
U.S. enters World War I, the
price of European imports
has begun to soar. The U.S.
experiences a shortage of
potassium permanganate.
Twenty-five-year-old Edward
Hegeler Carus, a mathematics
professor, comes home to La
Salle to find a solution. Carus
creates a makeshift laboratory
in an old barn behind his
family’s home in La Salle,
the Hegeler-Carus Mansion,
and begins developing a
process for the manufacture of
potassium permanganate.
1920s - In the aftermath
of World War I, potassium
permanganate prices drop,
forcing all U.S. producers out of
business. Of the more than 20
shuttered U.S. manufacturers,
Carus is the only one to
eventually reopen its doors.
Carus invests in new, more
efficient technology. By 1923,
the company is back in business.
1930s - In the mid-1930s,
Carus builds a new plant
for the manufacture of
two growing product lines:
manganese sulfate, and
hydroquinone. Carus was
the first company to provide
large quantities of manganese
sulfate to Florida for use in
fertilizer for the state’s sandy
soil. This fueled a boom in
Florida’s agricultural industry.
Hydroquinone is a chemical
used for developing photos,
which Carus manufactured
until the late-seventies.
1940s - World War II
1950s
New technology
installed in the
1950s drastically
improved Carus’
manufacturing
process.
1960s
CAIROX® (originally
spelled Carox) was
the first product
Carus promoted at
trade shows.

spikes demand for potassium
permanganate, used in nylon
production at the time.
Carus expands its facility
and operates around the
clock. For its wartime efforts,
Carus becomes one of the
first companies to be offered
the Army-Navy E Award.
Carus respectfully declines
the recognition, avoiding
publicity and possible threat
of sabotage.
1950s -Dr. Edward Hegeler
Carus gives management
responsibilities to his sons,
Blouke and Paul. Blouke
leads a significant plant
modernization, and after ten
years, Carus has patented
technological advances that
position the company as a
world leader in potassium
permanganate production. By
1961, a batch of potassium
permanganate, which had
taken a week to produce in
1951, was produced in 12
hours. Carus intensifies its
marketing and researches
new product uses. The
company develops the
potassium permanganate
method for water treatment,
and introduces it to cities
throughout the U.S.
1960s - Carus grows to
become the world’s largest
producer of potassium
permanganate. Production
capacity is at an all-time
high. Carus creates the brand
name CAIROX®, increases
its sales and marketing staff,
and strengthens its position
in diverse markets like metal
descaling, air purification, and
beeswax bleaching.
1970s-Carus offers new
environmental solutions
and new services to identify
and meet customer needs.
New solutions include air
scrubbing technology. The

Water Act are established.
Carus helps industries and
communities meet new
regulations.
1980s - Carus completes a
major plant expansion. One
year later, a global recession
and the loss of Carus’ largest
customer give Carus the
opportunity to demonstrate
its resilience. With research
and innovation, Carus
emerges with new solutions
for wastewater treatment,
air purification, and the
electronics industry. Carus also
enters the fashion industry,
developing a product used by
designers to create the iconic
stone washed denim look.
1990s -Carus enters the
soil remediation market
with technology that
treats chlorinated ethenes
(carcinogens found in
degreasers and dry cleaning
solvents), cleaning polluted land
so it is once again safe for use.
2000s- Carus acquires the
potassium permanganate
business of Industrial
Química del Nalón (IQN) of
Oviedo, Spain. The focus of
the newly-formed European
subsidiary is to grow Carus’
international market
reach. Inga Carus, formerly
European Sales Manager for
Carus Corporation, becomes
President and CEO in
2005, representing the third
generation of the Carus family
to lead the company.
2010s- Carus completes
its two largest acquisitions
to date: Alexander Chemical
in Indiana, and Sierra
Chemical in California and
Nevada, which manufacture
and distribute products
for municipal, agricultural,
mining, and industrial uses.
Carus is nationally
recognized for excellence
in community service as the
2010 recipient of the National
Association of Manufacturers’
Sandy Trowbridge Award.
The company also reduces
energy use at its largest
manufacturing facility twenty-
eight percent in five years,
becoming a four-time
recipient of the Responsible

Dr. Pamela Dugan, Market Program Manager
for Carus, travels often. Most recently she was in
Kentucky, performing product trials at a coal-mining
site. The mining process creates wastewater that must
be treated for heavy metal contamination before re-
entering the water cycle, and Dugan is one of several
Carus employees working with miners to develop the
most effective solution. Her trip is an extension of
work that began in La Salle, inside Carus’ research
laboratory.
“We’re very excited about our newest technology,
which provides a much-needed solution for metal
removal at mining sites located in remote areas. The
mines are tough to get to, but the mine water must
still be treated. Our customers appreciate that we
develop new products to help them solve some of
their toughest problems,” said Dugan.
Carus’ La Salle laboratory has a long history, not
unlike the company itself, and has held many of the
secrets to Carus’ century of success. In the company’s
earliest days, Carus’ research centered around finding
innovative ways to improve the manufacturing
process. Carus’ ability to produce better product faster
Inside
the Carus
Laboratory
In the 1960s, Carus intensified its product research, leading to advances in water treatment, soil remediation, and air purification.Today in Carus'
laboratory, innovators use specialty chemistries to create solutions for customers around the world, and young scientists gain experience and
knowledge from a century of expertise.

and more efficiently than the
competition was the reason it
survived the years following
WWI, when European exports
of potassium permanganate
put all other U.S.
manufacturers of the product
out of business.
In the 1960s, Carus
chemists shifted their focus
to explore new ways to
meet customer needs. In
the decades that followed,
Carus developed new ways
to treat contaminated water
and clean polluted air and
soil. Researchers developed
solutions for the electronics
industry, and even came up
with a product that helped
fashion designers create the
iconic stone-washed denim of
the late 1980s. Today, Carus’
laboratory staff remains
dedicated to ensuring the
highest product quality, and
using specialty chemistries to
create innovative solutions for
customers around the world.
Preparing for the next 100
years
Another key to Carus’
longevity is found in the
young people Carus invites
into the lab to learn about
what goes on there.
“The most vital resource we
can develop in our labs is the
next generation of talent that
will continue this important
work,” said Marie Marcenac,
Carus’ Vice President of Sales
and Marketing and Business
Development.
On any given day in Carus’
labs you may find interns
performing tests, school
groups taking tours, or new
hires learning the business
from experienced mentors.
“We look forward to seeing
new and returning interns
arrive each summer. They
apply their learning and
enthusiasm to new product
development, engineering
projects, or literature study.
They are challenged to apply
their skills to real life business
opportunities. The experience
leads some to return as
full-time Carus employees,”
said Dan Hartsough, Carus’
Product Development
Manager.
Katie Hoffert is a shining
example of young talent
finding opportunities to learn
at Carus. The 20-year-old
Biology and Biochemistry
major at Mount Mercy
University is completing
an internship at Carus this
summer. Hoffert, a native
of Hollowayville, IL, is the
winner of Carus’ Centennial
Scholarship contest, which
called on students across the
country to propose new ways
of using specialty chemistries
to create innovative
environmental solutions.
“Katie’s proposal was
highly creative and clearly
demonstrated an innovative,
well-thought-out solution
to the emerging issue of
finding ways to remove
pharmaceuticals from
drinking water,” said John
Katie Hoffert of Hollowayville is Carus’Centennial Scholarship winner.
Hoffert won a paid internship, and a $10,000 scholarship.

experience. I am doing
experiments and using
equipment that is all new
to me, so the amount of
knowledge I take home every
day is huge,” said Hoffert.
“Carus has given me an
opportunity to learn how to
help people in different ways.”
Whether an intern’s
education leads to a career
in medicine, or product
development, Carus
employees who mentor
students say they’re just happy
to have helped a young person
pursue a career in science.
“That’s our goal whenever
we interact with young people,
whether it’s through school
visits, internships, or plant
tours. We want to see them get
excited about science, because
careers in science provide
so many opportunities to
have a positive impact on the
world,” said Sean Davenport,
Technology Program Manager
at Carus.
“The most vital resource we can
develop in our labs is the next
generation of talent that will continue
this important work.”

100 years ago, Carus began with a single product, potassium
permanganate. Throughout the years Carus’ product lines
have grown to include many innovative solutions and specialty
chemistries. Still, potassium permanganate remains one of the
most versatile. Marketed primarily for environmental uses like
cleaning water, soil, and air, customers have found many uses for
the “chameleon chemical.” Here are some of the ways potassium
permanganate has been used in the last 100 years.

Have you ever noticed volunteers
picking up litter at the Illinois and
Michigan Canal in La Salle? Chances
are they’re Carus employees taking
part in Carus’ 19-year tradition
of keeping the canal clean. Less
visible to the public is the company’s
100-year tradition of continuous
improvement, which has led to major
conservation efforts at Carus’ La Salle
manufacturing facility.
The century-old company sells
products for removing pollution from
water, air, and soil, and Carus’ focus
on the environment goes far beyond its
product lines.
“Carus' commitment to education
and the environment drives our
community outreach programs,” said
Chairman and CEO Inga Carus.
To serve its neighbors in the Illinois
Valley, Carus has partnered with the
Illinois Environmental Protection
Agency and the Cities of La Salle and
Peru to offer free household hazardous
waste collection and electronics
recycling events.

Such efforts have led to
national recognition. In 2010,
Carus received the National
Association of Manufacturers’
Sandy Trowbridge Award,
given each year to one
company that best exemplifies
the giving spirit of the
manufacturing industry.
Carus has also received
widespread recognition for
green efforts within its plant
walls. In the last six years,
Carus has reduced energy
use at its La Salle facility
by 28%. The company
began participating in the
Department of Energy’s
Save Energy Now LEADER
program in 2009 and has
achieved greater energy
efficiency each year since.
In 2014, Carus received
the Illinois Governor’s
Sustainability Award. In a
letter to Carus’ Corporate
Engineering Manager Ralph
Moshage, former Gov. Pat
Quinn stated that Carus’
“commendable green
practices serve as a model of
environmental stewardship
for residents, businesses, and
institutions throughout our
state.”
“This achievement is the
result of plant-wide efforts
to operate in the most
environmentally-friendly
manner,” Moshage said.
“The award reflects the hard
work and diligence of every
employee.”
The Governor’s
Sustainability Award
is given annually to
Illinois organizations that
demonstrate a commitment
to environmental excellence
through outstanding and
innovative sustainability
practices.
“Carus’ provides innovative
environmental solutions
to customers around the
world. In staying true to
our company’s vision, we
are committed to operating
responsibly and sustainably,”
said Dave Kuzy, Carus’
president and chief operating
officer. “To be recognized
repeatedly by industry leaders
for our environmental efforts
is a great honor.”

Council has also recognized
Carus’ conservation
achievements with the
Responsible Care® Energy
Efficiency Award each
year since 2010. Twice, the
company has landed on a
short list of organizations also
receiving exceptional merit
distinction. Both times, Carus
was the only non-Fortune 500
company on the list.
In 2014, Carus was selected
by the Illinois Sustainable
Technology Center (ISTC)
to participate in the center’s
One Billion Gallon Water
Challenge. Carus is recycling
non-contact cooling water
used in its manufacturing
process, allowing the
company to cut its water use
significantly. The goal of the
ISTC challenge is to promote
water conservation efforts
by businesses, industries,
communities, and the general
public. ISTC is supporting
significant projects, such as
Carus’, as models of the type
of effort that will lead to the
conservation of one billion
gallons of water statewide.
Carus’ project alone will save
more than 60 million gallons
of water each year.
This year Carus partnered with the Cities of La Salle and Peru to provide two e-cycling events where residents were able to recycle TVs, computers,
and other old electronics.

Carus’ commitment
to education is a win for
employees, their children, and
many of your kids too!
At Carus, a typical year
begins with school science
fairs in need of judges.
Teachers know a call
to Carus can solve that
problem. The company has
professionals in chemistry
and engineering willing to
volunteer. Throughout the
late winter and early spring,
Carus employees teach
kids about business and
career planning as Junior
Achievement volunteers.
Summer brings Carus’
Summer Science Camp for
kids, the company’s internship
program, and the Scientific
Work Experience Program for
Teachers (SWEPT). Fall is full
of educational school visits,
chemistry demonstrations,
plant tours, and career fairs.
And all throughout the year,
Carus helps employees put
their kids through college
with a unique employment
benefit, the Tuition Assistance
Program (TAP).
Tuition Assistance
Carus has given more
than $3.8 million in tuition
reimbursement to help
students whose parents work
for Carus graduate debt-free.
“Carus has been an
extension of what our families
wish they could do on their
own,” said Jonathon Lauf, son
of Carus employee Shelley
Corban, thanking Carus
on behalf of all who have
received assistance. “In a day
and age when student loans
are a burden for so many
people, this help will allow
us to better provide for our
own kids and pay it forward.
We will be feeling the benefit
of this for years and years to
come.”
Lauf is one of 263 students
Tuition Assistance is
just the beginning

who have gotten help from
Carus since the company
started its Tuition Assistance
Program (TAP) in 1987. Carus
also reimburses tuition for
employees who pursue higher
education, but employees say
it’s the help made available to
their kids that sets Carus apart.
“It’s unheard of really,” said
Carus employee Tony Sparks,
whose son is enrolled in law
school with tuition assistance
from Carus. “For the company
to maintain TAP as a crucial
program, even through tough
financial times, is amazing.”
Carus covers up to 60%
of tuition expenses for TAP
participants, and a partnership
between Carus and Bradley
University means that for
those students attending
Bradley, the school waives
the rest of the bill. Carus
employee Ken Theisinger
has three sons, and all three
graduated from Bradley under
the program. His son Clay
is now Director of Teaching
and Learning at La Salle-Peru
Township High School.
“Someone’s educational
goals and dreams should
never be blocked by a fiscal
barrier. Thank you to Carus
for removing that barrier so
that my brothers and I can
pursue our dreams,” said Clay
at a recent reception held by
Carus to honor TAP scholars,
and celebrate the dreams they
are all pursuing.
Sparking an early interest in
science
Thousands of students
in the Illinois Valley and
surrounding areas see the
fun side of science each year
thanks to Carus volunteers
and Carus-sponsored
programs.
School visits bring
chemistry demonstrations to
auditoriums full of middle-
school students each year
as Carus takes part in the
American Chemical Society’s
National Chemistry Week. As
many as 40 Carus volunteers
take part annually, often
turning “Chemistry Week”
into “Chemistry Month”
and reaching more than
2,000 middle-school students
throughout the Illinois
Valley area.
Going beyond the classroom
“You better get ready for
some massive science fun!”
Ask La Salle 6th-grader Jack
Wallace what he would tell a
friend thinking of signing up
for Carus’ Summer Science
camp, and this is his answer.
He finishes with a rating, “ten
out of ten stars!”
Wallace, and twenty-
six other campers, spent a
week of their summer break

Getting teachers involved
Every teacher is asked
the question, “why do we
have to learn this?” at least
once. Carus’ Scientific Work
Experience Program for
Teachers (SWEPT) aims to
help teachers answer that
question with real-world
experience.

NEWSTRIBUNE REPORTER
What began in a barn
has evolved over 100 years
to become a modern-day
manufacturing plant.
Carus manufactures
chemicals that aid in cleaning
water, air, and soil. For
example, Carus products
can be found in protective
respirator masks.
It began as the United States
entered World War I. The
U.S. experienced a shortage of
potassium permanganate, used
in pharmaceuticals, saccharin
and pigment. Edward
Hegeler Carus, a 25-year-
old mathematics professor,
left teaching and made a
laboratory in a barn behind
his family’s home in La Salle.
Carus developed a process
to manufacture potassium
permanganate. By 1918
he had a new office, a new
laboratory, a new building.
Constant improvements in
Carus’ manufacturing process
allowed the company to
survive after the war, when all
US competitors went out of
business.
The plant today operates in
the same location where Dr.
Carus first made potassium
permanganate, behind the
Hegeler Carus Mansion in
La Salle. Ken Pisarczyk,
Blouke Carus Fellow and
Vice President of Carus
Technologies, has worked at
the plant 43 years, and has
seen many changes.
“Our manufacturing has
become participative, where
the operators are all there
to make decisions and not
just follow a rote recipe,”
Pisarczyk said. “We’re using
more statistical controls and
using more developed process
control technology than we
ever have the past.”
There is more automation of
A Century of Change,
Innovation, and Improvement
Carus has spent the last 100 years finding more sustainable ways to produce product. In 1951, the
company demolished its old smokestack. Now the manufacturing process uses hot water and creates
steam instead of smoke.

controls, he said.
“The engineering group has
been constantly working on
that,” he said.
This falls to Ralph Moshage,
Corporate Engineering
Manager, who has worked at
Carus for 19 years. He also
worked as an engineering intern
during high school and college.
“When I came back there
were three different control
rooms in the permanganate
plant,” Moshage said. “All the
walls were full of switches,
lights and timers and
recorders, everything had to be
turned on and off.”
In the late 1990s-early
2000s, Carus engineers began
upgrading.
“We put in programmable
logic controllers, PLCs, used
to control the process,”
Moshage said.
This made it easier to
troubleshoot problems. What
might have taken days now
takes just a few hours, he said.
Operators communicate
with the manufacturing
process via a desktop
computer, he said.
“The other thing we did,
we increased the amount of
information available to run
the plant more efficiently.”
Over the past five to six
years, electricity needed to
make permanganate has been
cut by more than 25 percent,
Moshage said. “The whole
idea is to make the plant more
efficient, more reliable and to
use less raw material.”
Increasingly, manufacturers
are focusing on sustainability
to stay competitive. Customers
are beginning to demand proof
of sustainable operations.
“You’re seeing a lot more
concerns about sustainability,
on being more environmentally
responsible, much more so
than we ever have in the past,”
Pisarczyk said.
Congratulations
Carus Corporation
on 100 years
in the community.

As Quality Control Manager at Carus, Lori Setchell’s job is to
work with her team to ensure customers consistently receive
top-quality products. In her 30 years at Carus, she has spent
a good deal of time sharing her workspace with young people
interested in science careers, guiding students who tour Carus’
laboratory, and mentoring interns.
“Education is important and encouraged at Carus, and it is one
of the most important messages we share,” Setchell said. Over
the years, Setchell has been pleased to see a growing number of
girls take an interest in chemistry and engineering, career fields
that have historically been male-dominated.
“Encouraging young women to be engineers or scientists
is a passion of mine,” said Setchell, who is proud to work for a
company that provides so many opportunities, and role models,
for young women as well as young men.
“At Carus, when I started thirty years ago, women were
working in the laboratory and even on the manufacturing floor,”
Setchell said.“Looking around Carus, professional women are
present in all areas, finance, manufacturing, quality, customer
service, human resources, and sales and marketing.”
“Carus is unique in both the chemical and manufacturing
industries, having a woman Chairman and CEO and a number
of women in key positions throughout the organization,” said
Carus’ Chief Financial Officer, Susan Buchanan.“I believe women
at Carus bring a strong sense of commitment, leadership, drive,
depth of experience, diversity and talent.”
Lori Setchell, Quality Control Manager at Carus, leads students on
a tour of Carus’laboratory. Setchell says inspiring young people to
pursue careers in science is one of the most rewarding parts of her
work at Carus.
