Clean Air System for Our Community
Tokai Carbon and the Addis plant have been a cornerstone of our community since 1969. We're committed to doing business the right way, and since acquiring the plant in 2018, we have invested More than $225 Million in a cleaner, healthier future for the people of Addis. Our state-of-the-art Clean Air System started operation in late 2023…, now makes our air cleaner than ever before.

Independent Regulatory Testing Confirms Compliance
At Tokai Carbon, environmental responsibility is a top priority. Local regulatory agencies, including the Louisiana Department of Environmental Quality (LDEQ), have conducted extensive air quality testing around our facility. The results? Zero findings of concern.
This independent verification confirms that our More than $225 million Clean Air System project is effectively reducing emissions and maintaining clean air standards well below regulatory limits.
General information
- You may have noticed a change in the skyline at the plant since the Clean Air System started operation in late 2023.
- The flue gas from the Clean Air System equipment now exits the stack at a much lower temperature (about 220 oF) and at a higher moisture content (about 25%). Thus, the flue gas now may be visible on cold days or when certain atmospheric conditions exist.
- The overall emissions from the plant are now much less than before the Clean Air System equipment was installed, which is a major benefit to the environment.
- The vast majority of the visible plume content is water vapor or water droplets.
