Research and Development in the Finnish Wood Processing and Paper Industry, c. 1850-1990
2018
This chapter describes the general history of research and development work in the Finnish pulp and paper industry from the mid-nineteenth century until roughly 1990, a period that witnessed it undergo drastic changes because of the altered political environment in Europe and general globalization. In addressing its subject, this chapter is mainly concerned with the operation of paper mills, but it also addresses the related subjects of technical research, formal higher education and work-related, practical learning. In addition, it briefly discusses the challenges inherent in researching the development of technology because of its research traditions. peerReviewed
ChemInform Abstract: Chemometrics: An Important Tool for the Modern Chemist, an Example from Wood-Processing Chemistry.
2010
This study briefly outlines the idea of principal component analysis and cross-correlation calculations (applied chemometrics) and presents an illustrative example from wood-processing chemistry. The applicability of chemometric data analysis was demonstrated by investigating the various structural changes that take place in dissolved and degraded lignin ("kraft lignin") during laboratory-scale kraft pulping of Scots pine (Pinus sylvestris) and silver birch (Betula pendula). The structural data (31P NMR and size exclusion chromatographic data) on kraft lignin were further processed by chemometric multivariate techniques (PCA and 2DCC), confirming, for example, that the cleavage of beta-aryl…

Two Family Firms in Comparison: Ahlström and Schauman During the 20th Century
2006
Ahlstrom and Schauman are among the most prominent companies in Finnish industrial history, being family firms engaged in different branches of economic activity. At first both were mechanical wood processing companies, but diversified later into the pulp and paper industry as well. Ahlstrom is even still today an important paper producer, whilst Schauman merged in 1987 with the Kymmene Corporation, and is nowadays a part of the UPM-Kymmene Corporation. This paper analyses the strategic decision processes undertaken in the named companies during the 20 century. The companies were not the most typical ones in the Finnish wood processing industry, but were, perhaps, typical examples of old fa…
