Traditional Manufacturing

This paper focuses on assessing the modes of research and development (R&D) collaboration and technological lifecycles in the Finnish pulp and paper industry. This traditional manufacturing industry is currently undergoing changes due to market and technological developments. By discussing industrial and technological lifecycles, this paper aims to establish the extent to which these changes affect the R&D collaboration networks in the industry. The paper also provides insight regarding how the incumbents in this industry change their innovation activities in the face of a new science-based technology — nanotechnology — which is argued to have a significant impact on innovative activities in many traditional and high-tech industries. The results suggest that the Finnish pulp and paper industry is adapting to the changing innovation environment by increasing internal R&D investment and by extending and diversifying its R&D collaboration networks. The results also indicate that nanotechnology is seen as a potential new source of business for the pulp and paper industry but that investment will be required, particularly in absorptive capacity, to take advantage of these new technologies.

Abstract The pulp and paper industry is a highly energy-intensive and water-consuming industry. This industry is known for the utilization of a wide range of raw materials, containing cellulose fibers (generally wood, recycled paper, and agricultural residues), for the production of various grades of paper. There are several processes involved in the conversion of raw materials to the paper product such as raw material preparation, pulping, pulp washing and screening, bleaching, stock preparation, papermaking and chemical recovery. All the processes are facing issues regarding process efficiency, product quality, energy & water consumption, and cost and environment. There is a need for further improvement and upgrading the technologies but the scale of operations, technological obsolesce and cost of implementing new technologies are some of the major issues. The main thrust areas of pulp and paper processing require major interventions in the adoption of green and clean technologies.

Xylan Content

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.
