2021 Mill Operations Timeline

Prior to 2020, the New-Indy Catawba mill produced mostly white paper, which was used by customers to print magazines, catalogs and similar materials. Last year, New-Indy converted portions of the mill to manufacture unbleached containerboard, which is used by customers to produce various packaging products. The mill was completely offline from May to September 2020 during the conversion process. The first stage of restarting production began in December and by February 1, 2021, the mill had restored operations. On February 8, 2021, New-Indy Catawba LLC sent DHEC a letter notifying it that New-Indy Catawba began operations of all equipment except the No. 2 Paper Machine within 15 days prior to that letter.
