Abstract
  • Hardwoods, including aspen, comprised 22 percent of the pulpwood. received in the New York and New England States pulp mills in 1944 when war-time conditions fa­vored the use of all available wood. The denser hardwoods alone, however, amounted to only 9 percent of all the pulpwood, and this value is reduced to 7 percent when imports are subtracted. Possibilities for increasing hardwood utilization lie in using domestic instead of imported hardwoods, using a minimum of 10 percent hardwood fiber in present paper grades, constructing new sulfate and semichemical mills for producing strong hardwood pulp for definite uses, and changing certain paper grades to accommodate more hardwood fiber. If all these possibilities were realized, it is estimated that the consumption of domestic short-fibered wood could be increased from 14 to 33 percent on the basis of 1944 data. Although the technology of the use of hardwoods is sufficiently advanced to per­mit major increases in their utilization, research is urgently needed to show how a much better ground-wood pulp can be made, to determine the variables of chemical pulping, and to improve fiber-processing and paper-making procedures.
