"Modern Karton - Rise to the Top" discusses stock preparation upgrades that increased capacity while saving energy, including fractionation and low-intensity refining to preserve strength for 100% recycled fiber.
This paper discusses screening upgrades to increase capacity by combining old with new equipment while recovering more fiber, reducing energy use and using fractionation to preserve strength.
"Faster and Smoother" describes Ciacci's new POM wet end system that reduced defoamer use by 75% and their new MaxSaver rejects screen for fiber recovery.
