With the environment in focus three different fiberlines ranging over a 20-year-period are compared. It is concluded that the environmental operation has significantly been boosted over the years. Today's challenges in the R&D activities relating to fiberline technology include e.g. improved pulp yields and prevention of yellowing of fully bleached pulp. A method for determination of mill pulp yield is presented, and the latest modified cooking concept briefly discussed in relation to the higher yields obtained. The topic of yellowing is discussed and hot chlorine dioxide bleaching is presented as a tool to reduce the yellowing tendency.
