BENNINGTON, NEW HAMPSHIRE—  Monadnock's certified product portfolio includes Envi Card Stock 28 pt and Envi Paper Card 30 pt options in both Virgin and 100% Post-Consumer Waste (PC100) content. These substrates provide the industry with a viable, eco-conscious alternative to traditional plastic cards, reducing reliance on fossil fuel-derived materials while maintaining superior quality and performance. Mastercard’s CEC certification process was originally developed for plastic cards, making Monadnock’s achievement a significant industry first. Since launching its Sustainable Card Program in 2018, Mastercard has worked to transition more than 168 million plastic cards to recycled and bio-based materials—reflecting a growing push for more responsible alternatives. Since no paper-based card had been certified until now, Mastercard refined its assessment criteria—a considerable task—to account for the unique attributes of fiber-based materials. Monadnock Paper Mills, Inc., the oldest continuously operating paper mill in the US.
