CHAPTER 22 

 Solid Wood Products 



As used in this chapter the term "solid wood products" includes not only 

 lumber, but most products except pulp and paper (chapter 25), fiberboards 

 (chapter 23), and reconstituted wood (chapter 24) such as particleboard, flake- 

 board, and composite board having veneer faces over a flake or particle core. 

 Furniture, plywood, glue-laminated beams, glue-laminated veneer, pulp chips, 

 and energy wood are considered solid wood products under this definition. 



Mulches and soil conditioners of both wood and bark are discussed in chapter 

 13. 



Analysis of materials flow from forest to mill (figs. 2-1 and 2-2) indicates that 

 the largest portion of hardwood roundwood harvested in 1970 in the United 

 States was converted into solid wood products — principally lumber; by the year 

 2000, however, consumption of pulp and fiberboard will predominate, as fol- 

 lows (Boyd et al. 1976):

Sawlogs for lumber 24.51 42.16 



Veneer logs for plywood 2.28 3.09 



Veneer logs for lumber laminated from veneer — 1 .59 



Roundwood for structural flakeboard — 1 .22 



Roundwood for pulp and fiberboard 19.70 78. 14 



Miscellaneous industrial wood and fuel wood 1 1 .56 7.21 



Total 58.05 133.41 



As industry progresses .toward more complete utilization, products such as 

 energy wood, chips for fiber, and wood for structural flakeboard will signifi- 

 cantly increase commodity recovery per tree and per acre. Solid- wood products 

 recovered from hardwoods considered culls in the 1970's will also increase. 



Trends in consumption of species and products, and product prices, are 

 graphed in chapter 29. In chapter 28, economic feasibility studies of enterprises 

 manufacturing solid wood products are abstracted. 



Some of the key processes by which hardwood is converted to solid wood 

 products are discussed at length in preceding chapters, as follows:
