TENNESSEE (News release) -- Domtar's Kingsport Mill recently produced its first 100% recycled containerboard. The milestone marks the culmination of a two-year, $350 million investment project to convert the former uncoated freesheet paper mill into Domtar's first 100% recycled packaging facility.

"This is a monumental day for Domtar that marks our official entry into the containerboard market," said Steve Henry, Domtar executive vice president and chief operating officer. "I am proud of the packaging, mill and extended Domtar team for their hard work and commitment. We are also grateful to our community for their support throughout the project."

The Kingsport Mill is the largest recycled manufacturer in Tennessee, home to the second-largest recycled containerboard machine in North America. Each year the mill will convert about 660,000 tons of recovered fiber into high-quality recycled performance linerboard and corrugated medium.

Domtar will hold an official grand opening celebration at the Kingsport Mill in 2023.
