We have great capabilities in papermaking at NC State. At bench scale, sheet moulds are available in a variety of sizes, with and without white water recycle. For pilot production of paper, the 12-inch “Wolfpack Baby” fourdrinier permits a cost-effective evaluation of a variety of furnishes and conditions.
