Abstract
A process is provided for delignifying lignocellulosic material, including feeding a lignocellulosic blend comprising a Western Red Cedar (WRC) chip furnish and a second lignocellulosic material into an aqueous alkaline pulping solution at the feed end of a digester to produce a lignocellulosic mass. The second lignocellulosic material is provided in a proportion that increases the density of the mass to enable the mass to move through the digester while minimizing production effects associated with low density WRC chips. The mass moves through the digester to produce a pulp that may be bleached.
