For many paper machines producing printing and writing grades the introduction of recycle pulp or increasing the amount of recycle pulp can be a challenge. Most operations will purchase recycle lap pulp and add 10% or more to the furnish mix. The addition of recycle pulp can cause issues and introduces a level of uncertainty with respect to stickies content and impact on runnability. Most operations depend on macrostickies count to determine the stickies content level but the measurement is not always reliable for preventing a stickies outbreak on the paper machine. The unknown possibility of issues for any given bale of recycle lap pulp means many operations will limit or refuse to use recycle fiber.
