English title: Opportunities of Finnish forestry and forest industry in the market of Continental Europe.

The article summarizes import and export of timber and manufactured wood products in Europe before the Second World War, and outlines which are the opportunities of import and export after the war. The evaluation is based on statistics of 1936 and 1937. The export balance of Europe was positive; when all the timber assortments were included, Europe exported almost 10 million m3 more timber than it imported. Export and import of round timber were almost in balance, whereas export of paper products was about 12 million m3 larger than import. Consequently, European forest industry reached its magnitude before the war through export overseas. Foreign markets have been important especially for countries like Finland and other Nordic countries.

The war has disturbed the markets. In a scenario where Europe remains a closed sub-area in the global market, there is 10 million m3 excess of timber and wood products. Within Europe, United Kingdom is the greatest importer of timber and manufactured wood products. If UK was excluded from the European market, it would mean a big change in the export and import balance within the area. In 1936 and 1937 the import would have been only 45% and 55%, respectively, of the export if UK is not included in European numbers. If also Russia is excluded from the European sub-area, it would affect especially the export of round wood, sawn timber and plywood. Nordic countries have accounted for about 80% of European paper products export before the war. According to the article, Finnish wood resources do not allow big increase in sawn industry. However, there is potential in increasing demand of pulp in continental Europe in future. In general, Finnish forest industry would have to decrease the production, if the markets would be limited to the European sub-area.

English title: The consumption of wood in forest manufacturing industry in Finland in 1925-1935.
English keywords: saw industry; pulp industry

The consumption of wood and the value of the wood in the forest manufacturing industry in 1925‒1935 was studied using the official industrial statistics as the main source of data. The annual wood consumption of sawmills, plywood industry, match production, wood-wool industry, spool production, mechanical pulp mills, sulfite pulp mills and sulfate pulp mills was in average 15.6 million cubic meters, of which 4.0 million m3 was pulpwood, 11 million m3 saw logs and 0.44 million m3 veneer timber. The spool production used 163,200 m3, match production 39,900 m3 and wood-wool production 7,900 m3 of wood. When the wood consumption is at its maximum levels, the fellings cannot be increased sustainably. Thus, the sawing cannot be increased from the present level. The growth of pulp industry has created demand for small timber, and in that industry there is room for expansion.

English title: Investigations into the costs of raw material in the Finnish pulp industry.

The article is a review on the wood procurement and cost of pulpwood in the Finnish mechanical and chemical pulp industry in 1922‒1926, based on statistics collected from the members of the Central Association of the Finnish Woodworking Industries (now Finnish Forest Industries), and the series Statistics of Industry and Foreign Trade. Wood trade is carried out by three types of sale: standing sales where the buyer of the wood takes care of fellings and transport (55% of the volume), contracts for the delivery of pulpwood (45% of the volume), and fellings in the own forests of the industry. Norway spruce (Picea abies (L.) H. Karst.) was the most important tree species, and was used almost exclusively especially in the mechanical pulp mills. According to the study, the demand of pulpwood increased markedly during the period. The stumpage prices did, however, not increase accordingly until in 1926. It is assumed that also the supply of wood was high after the World War I.

English title: Wood consumption of wood manufacturing industry in Finland in 1911‒1929.

The main source of data was the official industrial statistics in 1911‒1929. The data was complemented with information from other sources, and the figures converted to solid volumes under bark. The wood consumption of wood manufacturing industry in the period varied strongly, being lowest in 1918 (2.2 million m3) and highest in 1927 (18.1 million m3). The wood consumption dropped during the World War I.

The wood manufacturing industry in Finland concentrated on sawmilling industry which has used annually 70‒80% of the wood consumed in the whole wood manufacturing industry. Other sectors of industry using wood were plywood industry, wood-wool industry, spool factories, match industry, mechanical pulpwood industry and pulp industry.

English title: Development of stump utilization in Finland.

The utilization of stump and root wood is analysed in this paper on the basis of literature from middle of 19th century to the present date. According to the information available, the utilization of pine stumps in tar production was small compared to that of peeled Scots pine stemwood in the 19th century. During the 1st and 2nd World War the utilization of stumps for tar production reached its highest levels. Other industrial utilization of stumps has been small up to the present time but now stumps are beginning to be used in the pulp industry.

The greatest amounts of stumps have been utilized by the rural population. Stumps were used as fuel. In the thirties, the yearly amount used was over 200,000 m3 (solid measure), and even in the sixties over 100,00 m3. No industrial utilization method has yet reached these levels.

English title: Using possibilities of barking waste in sawmill industry specially using as a soil improver and substrate for plants.

Residue of the wood is good raw material for pulp and board industries, but the question of the use of barking waste still remains to a great extent unsolved. This research deals with the possibilities to utilize the barking waste of sawmill industry in general and, in particular, its use as a soil improver and substrate for plants. It also explains the industrial manufacturing method of composted bark, bark humus, developed by the author as well as the properties of bark humus and the economy of bark humus and the economy of manufacturing.

English title: Waste wood of the Finnish sawmill industry. A study of the use of waste wood and its profitability.

The purpose of this investigation was to construct a procedure for measuring the profitability of the use of waste wood. The average price a sawmill gets from the waste wood depends, on the amount of use compared with the waste wood output, and on the composition of waste wood. Production of different kinds of waste wood presupposes investments, therefore, the size of a sawmill, in addition to its location, affects the composition. The data was collected by mailing a questionnaire through the central organizations of the sawmill industry in 1959.

The amount of waste wood per standard of sawn wood increases with the size of the sawmill. Because small sawmills cannot generally use or sell their waste wood, they strive at using the raw material effectively. In addition, they produce much rough-edged sawn wood, and sorting is not as strict as at large sawmills. They also leave their sawn wood untrimmed.

Finland’s pulp industry has expanded significantly since 1958. This has increased the need of raw wood, and the demand of sawmill waste. An additional data collected showed that in 1958 there was about 150 and in 1963 about 200 sawmills delivering waste wood to the forest industry. The amount of waste wood used as raw material compared with the total waste wood utilization had increased about 10% during the period. The production of cellulose chips became profitable when the annual output of sawn wood of a sawmill exceeded 1,000-2,000 stds. The size structure of the sawmills affects the regional usage of the waste wood.
