BRADLEY COUNTY, TN. (WRCB)-- A Bradley County plant will phase out its use of mercury.
Olin Corporation announced Friday it will invest 160-million dollars to expand its plant in Charleston.
The company makes chemicals like chlorine and bleach.
For decades, they've used mercury cell technology, which in this green age, is highly unpopular.
Olin admits they've lost business in recent months, and they're phasing out mercury-based production.
The expansion won't create any new jobs.
