Abstract

The invention relates to a method for the pre-treatment of chips, which can be used to reduce the specific energy consumption of mechanical pulp and to improve the technical properties of the fibres. In the treatment, chips in a liquid phase are brought into contact with an enzyme preparation containing cellobiohydrolase and endoglucanase
