When did Penta production end?

The manufacturing of pentachlorophenol officially came to an end in December of 2021. This was the last location anywhere in the world that made pentachlorophenol.  However, penta will continue to be available from some pole producers for at least another year. Pole treating plants are working through their penta inventories while others have already converted to alternatives.
