My TAPPI Story: Naomi Gehling
USDA Forest Service
Infestation of the Dendroctonus rufipennis beetle has resulted in large stands of dead and dying timber on the Kenai Peninsula in Alaska. Tests were conducted to evaluate the value of beetle-killed spruce as pulpwood. The results showed that live and dead spruce wood can be pulped effectively. The two least deteriorated classes and the most deteriorated class of logs had similar characteristics when pulped; the remaining class had somewhat poorer pulpability. The more deteriorated wood required the same or slightly less refining energy to achieve a certain level of freeness. The presence of sap rot decay was found to be an important indicator of pulping efficiency and resultant pulp quality. Log deterioration had mixed effects on paper properties.
