Abstract [en]

 

The pulp and paper industry is energy intensive and consumes large amounts of wood. Here, the total biomass use is estimated for the production of one tonne paper in a cradle-to-factory gate scope, assuming that all energy, including electricity and motor fuels, are produced from forest biomass. We consider the production of newsprint made from mechanical pulp; lightweight coated paper from a mixture of mechanical and chemical pulp; and fine paper from chemical pulp, under Swedish conditions. The results indicate that chemical pulp papers require less biomass resources per tonne of paper produced than do mechanical pulp papers. For mechanical pulp papers, external electricity requires the largest part of the biomass. Motor fuel production accounts in no case for more than 10%. Between 27% and 38% of the total biomass used is embodied in the paper product, indicating that waste paper recovery options are important.
