You’ve probably seen the flags. If you drive down Route 50 in Bourbonnais or pull into the Lowe’s across the street, the massive 140-acre campus of CSL Behring LLC Kankakee IL is impossible to miss. It’s a beast of a facility. Most locals know it as "the old Armour plant" or just "the plasma place," but that barely scratches the surface. Honestly, calling it just a factory is like calling the Sun a "lightbulb."
This site is one of the biggest biotech manufacturing hubs on the planet. It doesn’t just "make stuff"—it keeps people alive.

The Kankakee Powerhouse Nobody Talks About
While everyone focuses on tech hubs in Silicon Valley or the massive warehouses popping up in Will County, Kankakee has been quietly housing a global titan. We’re talking about 40 buildings and over 1,800 employees. In fact, CSL Behring represents about 20% of the entire manufacturing workforce in Kankakee County. That is a staggering concentration of specialized labor in one spot.
Most people assume the facility is just a giant fridge for blood. Wrong.
The Kankakee site specializes in plasma fractionation. This isn't just basic lab work; it's a high-stakes, incredibly complex process of separating specific proteins from human plasma to create life-saving biotherapies. They’re making things like albumin—used for trauma and burn victims—and immunoglobulins that treat rare immune deficiencies.
Why the $1.5 Billion Expansion Matters
If you’ve noticed the construction and the new traffic light at the entrance, there’s a reason for the mess. In late 2025, CSL announced a massive $1.5 billion investment across its U.S. operations, with Kankakee sitting right at the heart of that strategy.
They aren't just adding a few offices. This is a multi-year plan to beef up the domestic supply chain. Why? Because the U.S. provides the vast majority of the world’s plasma, but we haven't always had the onshore capacity to process all of it into finished medicine. Kankakee is the bridge that fixes that.

- Job Growth: This expansion isn't just for show; it’s expected to create hundreds of high-paying biotech jobs in a region that has historically leaned on heavy manufacturing.
- Infrastructure: The company recently dropped $35 million just on a new electrical substation to keep the campus running. They’re basically running a small city’s worth of power.
- The Traffic Light Saga: It sounds silly, but it took years for the state to approve a simple traffic light for the plant's entrance. It’s now a symbol of the site’s sheer scale—the shift changes are so massive they literally require a coordinated highway signal to prevent gridlock.
CSL Behring LLC Kankakee IL: Beyond the Lab Coats
People often confuse the manufacturing plant with CSL Plasma donation centers. It’s a common mix-up. CSL Plasma is the retail-facing side where you go to donate your plasma for a bit of extra cash. The facility on Pharmaceutical Drive? That’s where the "magic" happens.
In April 2023, they actually opened a brand-new plasma donation center right on the Kankakee campus. It was a soft launch for employees first—sorta like a "don't just make the medicine, provide the raw material" vibe. Now, it's open to the public, featuring the new "Rika" collection devices that cut down donation times significantly.
The Armour Legacy
You can’t talk about CSL Behring without acknowledging the history. This site isn't some new-age startup. Its roots go all the way back to the 1800s with the Armour company in Chicago.
Back then, they were focused on meatpacking, but they realized the "by-products" (glands and tissues) had medical uses. That evolved into Armour Pharmaceuticals, which eventually landed in Kankakee. It’s a weirdly poetic evolution from the stockyards of Chicago to a high-tech facility treating rare diseases like von Willebrand disease and Alpha-1 antitrypsin deficiency.
What’s Next for the Site?
Looking toward the rest of 2026, the Kankakee facility is in a state of constant evolution. CSL is leaning hard into Pharma 4.0. That’s basically just a fancy way of saying they are automating as much as possible to ensure the medicine is perfectly pure.
However, it hasn't all been smooth sailing. In late 2025, the company did some restructuring, which led to some layoffs in the filling departments at the Kankakee site as they shifted focus toward more efficient, globalized processes. It’s the reality of a multinational business: constant shifting to stay ahead of the competition in Switzerland and Germany.
Actionable Insights for the Community and Job Seekers
If you are looking to get a foot in the door at CSL Behring LLC Kankakee IL, stop thinking of it as a factory job. It’s a career in life sciences.
- Check the Specialized Training: The company often partners with local colleges like Kankakee Community College (KCC). They look for people with backgrounds in chemistry, biology, or even specialized logistics.
- Monitor the Expansion Phases: With the $1.5 billion investment still rolling out through the next few years, hiring waves for maintenance technicians, lab analysts, and quality control specialists are going to be frequent.
- Understand the Shift Work: This is a 24/7 operation. If you want in, be prepared for unconventional hours; the molecules don't stop moving just because it’s 3:00 AM on a Sunday.
- Local Economic Impact: For residents, this means the demand for housing in Bourbonnais and Bradley isn't going away. The county is currently struggling with a housing shortage because of the influx of workers for CSL and the nearby Gotion plant.
The Kankakee site is no longer just a local employer. It’s a linchpin in the global pharmaceutical supply chain. Whether you're a donor at the new center or a technician in the fractionation lab, what happens behind those fences on Route 50 affects patients thousands of miles away.
