2021 – 2024 Mill Operations Timeline
Prior to 2020, the Catawba Mill produced mostly white paper, which was used by customers to print magazines, catalogs and similar materials. New-Indy converted the mill to manufacture unbleached containerboard, which is used by customers to produce various packaging products. Following the conversion, the mill experienced upset conditions that required remediation efforts and operational improvements. The timeline below outlines New-Indy’s operational updates since 2021.
