Chipping and Pulping Dead Trees of Four Rocky Mountain Timber Species

摘要

Evaluation of dead trees of four Rocky Mountain species as raw material for pulp and paper indicated that 14 to 30 percent more horsepower was required to chip dead trees than green trees. Dead trees produced a slightly greater percentage of fines than did the green trees. No problems were encountered in separating the bark from the wood chips or in pulping the dead lodgepole pine chips.
