At the corner of Kankakee County’s busiest intersection, CSL sits on 150 acres and is the County’s largest manufacturer. The company employs approximately 1,420 people, and with the recent announcement of a $1.5 billion expansion, an additional 300 jobs will be created.
The project includes a new 300,000-square-foot, three-story facility dedicated to producing immunoglobulin therapies. This expansion will enable CSL to bring its full manufacturing process – from plasma collection through filling and packaging – entirely to the United States.
This $1.5 billion investment marks the largest in the State of Illinois in 2026 and builds on a series of major developments in recent years, including a ComEd substation installation in 2024, a plasma site in 2023, a wastewater treatment facility in 2021, and a seven-story building completed in 2014.
