Based on the development concept of Russian pulp and paper industry up to 2015 the possible directions of its post-crisis growth and current trends are identified. One of optimal directions to achieve the environmental and resource saving effects in the pulp and paper industry is the introduction of best available technologies. The scientific potential assessment of domestic developments related to some of the best modern biotechnologies that could create a new conceptual basis for evolution of technologies in the pulp and paper industry and improve the environmental industrial safety is given in this paper.

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.
