Pulp And Paper Industries

The pulp and paper industry is generally considered the most technologically progressive of the forest industries. A study employing Solow's method indicated a rise in the index of technological change of 50% between 1940 and 1960. This compares with a 547% increase for the chemical industry. Derivation of the capital production function for the pulp and paper industries shows that all increases in productivity, 1940–1960, were due to change in technology. There is also some indication that optimal plant size has been reached.

Agricultural residues and energy crops are promising resources that can be utilized in the pulp and paper industry. This study examines the potential of co-cooking nonwood materials with hardwoods as means to incorporate nonwood material into a paper furnish. Specifically, miscanthus, switchgrass, and corn stover were substituted for poplar hardwood chips in the amounts of 10 wt %, 20 wt %, and 30 wt %, and the blends were subjected to kraft pulping experiments. The pulps were then bleached with an OD(EP)D sequence and then refined and formed into handsheets to characterize their physical properties. Surprisingly, all three co-cooked pulps showed improved strength properties (up to 35%). Sugar measurement of the pulps by high-performance liquid chromatography suggested that the strength increase correlated with enriched xylan content.
