Cascades Inc. announces that it will progressively and permanently close tissue production and converting operations at its Ransom and Pittston plants, located in Pennsylvania, between December 7 and January 31st of 2021. The two paper machines at the Ransom plant have a total annual production capacity of 50,000 short tonnes of tissue paper. Currently, the conversion of this volume into 6 million cases of product occurs primarily at the Pittston plant. These volumes will be moved to other Cascades plants and filled with additional capacity. The two sites employ a total of 229 workers. "The aging equipment of these facilities, the low profitability, the high logistic costs and our recently announced investments in other production and converting units in the U.S. have prompted us to move production to our other sites to optimize operational efficiency." said Jean-David Tardif, President and Chief Operating Officer of Cascades Tissue Group.
