Sustana Fiber Signs Commitment to Increase Paper Cup Recycling
Sustana Fiber along with a group of prominent paper mills and end markets across North America signed a declaration of acceptance and a commitment to increasing recycling of paper cups. The group includes Essity, GP PRO, Graphic Packaging International, Great Lakes Tissue Company, ND Paper, Pratt Industries, WestRock and Sustana Fiber. These organizations representing 75% of mixed paper demand (by quantity consumed) in the U.S. and Canada are accepting paper cups. Seven companies with 25 paper mills actively accept residential mixed paper bales (ISRI grade 54) with paper cups included, while three companies with five facilities currently accept paper cups when included with aseptic and gable top cartons in carton bales (ISRI grade 52). Paper cups have a coating on the inside (for hot drink cups) or on both sides (for cold drink cups) that provides a liquid barrier to the fiber. Although the coating has long been seen as a reason not to recycle paper cups, several companies have conducted tests and determined that the coating does not present an obstacle to recycling the cups in their facilities. The mills use pulping systems that separate the coatings from the fiber, recovering the fiber with a 70% to 90% yield.
