Re: TCF Pulp Market & Pulp strength

  As per information from UPM-Kymmene's (world's second largest (by volume)
  paper company) director of R&D, Dr. Kari Ebeling, UPM-Kymmene has found
  that there is a four percent increase in hardwood consumption during
  production of bleached hardwood kraft pulp with TCF method in comparison to
  the corresponding ECF production.  The company also found that the tear
  strength of TCF bleached softwood pulp has been about 5 to 10 percent
  weaker than that of the ECF bleached softwood pulps.  This means that the
  mill needs to increase the amount of softwood pulp in order to provide the
  same reinforcement capability into the magazine papers than in the case of
  the corresponding ECF bleached softwood pulps.
  In regards to the comments about a market for TCF pulp, it only has
  occupied six percent of the world bleach chemical pulp market for the past
  three years.  ECF's market continues to grow this year surpassing all other
  bleaching processes commanding 50 percent of the world market.
  If you have any questions about ECF bleaching processes or market trends,
