Input distance function and index number methods are used to analyze productivity and efficiency in the Canadian pulp and paper industry. Productivity growth is decomposed into components that have different managerial and policy implications. The conventional productivity measures from the study are also compared with environmentally sensitive measures that take into account changes in pollutant outputs. The paper finds that most of the productivity growth indicated by index number methods is due to output scale effects rather than true productivity growth resulting from technical progress or improvements in the degree of productive efficiency. Researchers are advised to employ methods that allow for the identification of different productivity growth components. The results also show that conventional measures that ignore pollution abatement activities understate true productivity growth in the industry.

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.
