About Us

Cosmo Specialty Fibers, Inc. (CSF), an affiliate of The Gores Group, was created to restore, restart and operate the former Weyerhaeuser Specialty Cellulose Mill in Cosmopolis, Washington. With the goal to build on the Weyerhaeuser legacy of producing a high-quality dissolving wood pulp, CSF resumed market-grade pulp production on May 1, 2011 and is working to operate a more efficient facility, thus ensuring the company’s financial viability. Our priorities include implementing world-class safety standards, demonstrating best-in-class environmental impact status and a providing a commitment to the values of the surrounding communities. We believe that the mill is a long-term business built on the basis of a robust product market, superior Hemlock fiber and full government support at all levels.
