Over 80 Years
of American Innovation
Born out of wartime necessity, Calgon Carbon now leads the charge in air and water treatment with American-made solutions.
Since 1942, Calgon Carbon has been the American cornerstone of activated carbon innovation. Founded during WWII, we pioneered the use of domestic bituminous coal to replace vulnerable coconut imports, and we’ve been setting the standard ever since. As the largest manufacturer of activated carbon in the world, we deliver unmatched expertise, supply security, and regulatory confidence, all powered by American ingenuity.

Calgon Carbon, the original name in Activated Carbon:
Domestic Manufacturing
Our principal production and reactivation facilities are in the U.S., using coal mined from domestic regions, not fragile, foreign-dependent supply chains.
Technical
Leadership
Calgon Carbon has the most experienced team in the industry, ready to support system design, troubleshooting, and compliance strategy.
Sustainable Reactivation
Our reactivation process removes and destroys organic contaminants, in compliance with local, state, and federal law, and significantly reduces your environmental footprint.
Proven American Roots
We answered the nation’s call in WWII. Today, that same spirit drives us to protect water, support communities, and build a safer future.
Choose a supply chain you can count on, for compliance, performance, and sustainability.
Foreign carbon sources introduce hidden burdens that erode reliability and undermine long-term performance:
- Unverifiable quality across international vendors
- Unpredictable lead times and cost uncertainty
- No end-of-life solution for spent carbon
- Minimal environmental accountability or traceability
Solving for PFAS and other organic compounds is only the beginning.
Operation Bedrock helps utilities and industries build a future-ready strategy for water and air treatment.
“Operation Bedrock reflects what makes Calgon Carbon different: real infrastructure, proven science, and the kind of American reliability that customers can count on when everything else is uncertain.”
