On the other hand, every effort is made to avoid wood waste due to debarking for cost reasons. Both factors must be taken into account in order to achieve the best possible financial result. At sawmills, the financial interests associated with debarking are significant, as the amount of debarking is one of the payment bases for sawdust used for pulp production. For example, in the Nordic countries, more than 1% of the number of bark drops the price paid for wood chips, and on the other hand, several mills pay compensation if the number of bark is less than 0.5%, for example. The purpose of peeling is to break the backing layer (Cambium) between the bark and the wood and to separate the bark from the wood. This is achieved by applying such a large force to the backing layer that the stresses it causes break both the bond strength and the bond strength between the wood and the shell. Peeling properties depend on the bond strength between the wood and the bark, the structure of the bark, the shape and quality of the wood, and the conditions of peeling. There are differences in the characteristics of different tree species, and large variations can also occur in the same tree species, e.g. due to the growing area. Regardless of the type of wood, peeling of frozen and dried wood is always more difficult due to the higher bond strength of the bark and the wood.
