 Pulp and Paper 



Information on demand and trends contained in section 25-1 is principally 

 from U.S. Department of Agriculture, Forest Service (1980), papers by R. H. 

 Reeves, and graphs from R. P. Whitney and the American Paper Institute. In 

 section 25-2, definitions of paper types are from the American Paper Institute. 

 Subsections on trends in mechanical and semichemical pulp production, neutral 

 sulfite semichemical pulping, and green liquor semichemical pulping (in sec. 

 25-6) are condensed from a review by J. W. McGovern and R. J. Auchter. 

 Section 25-7 on chemical pulping is from a review by H. A. Schroeder; B. K. 

 Mayer provided the description of a kraft chemical recovery furnace.
