The purpose of this study was to update hypothetical “reference mills”, representing the state-of-the-art of pulp and paper production in the Nordic countries. These model mills have been developed in several versions going back all the way to the 1970s.

The main emphasis has been on solutions which have affected energy use and electricity production. The reference mills have typically been used for benchmarking and for evaluating new process concepts in relation to the reference concept.
This report describes mills that produce dried and bleached kraft pulp to be sold on the market. The mills would be self-sufficient in both power and steam with only the recovery boiler and back pressure turbine. The mills have a power boiler to make use of surplus bark and wood waste, and for sludge recovery. There is an excess of steam from the recovery and power boilers which is utilized in a condensing turbine to produce renewable power for export.
