The objective of this work was to analyze the prospects for the next five years in relation to planted area, forest production, investment intention and hiring of employees. The research had as its area of coverage the state of Paraná and as a source of data, companies (legal entities) producers of forest raw material of planted origin that operate in the state. The contacts with the companies were obtained from the Paraná Association of Forest Based Companies (APRE), the Organization of Cooperatives of the State of Paraná (OCEPAR), SINPACEL and ABIMCI. The questionnaires were sent by e-mail to the entire contact base, aiming at the census. Thus, the resulting sample is made up of 41 companies, segmented between integrated and non-integrated companies, which corresponds to 17 and 24 companies. The evaluation answers were carried out. For the identification of the companies’ prospects, it was requested to fill in a table indicating a percentage (0 to 100%) that reflects the projections for the next 5 years. The prospects related to the planted area, production and investments were positive, however, the panoramas related to hiring new employees by the pulp and paper industry (integrated companies) presents a prospect of reduction. The Timos are the group that has the most positive expectations, being responsible for the expansion of the planted area, volume produced, investment and hiring of employees.

The aim of this study was to investigate the effect of using whey powder (different concentrations and treatment repetitions) as a probiotic agent on the quantitative and qualitative properties of stored bagasse intended for use in the pulp and paper industry. For this purpose, whey powder was added in three concentrations and the treatment was applied once or twice. After that, soda pulp was prepared under conventional conditions. Then, handsheets (80 g/m2) were made and tested in terms of paper properties, and the results were compared. The findings revealed that increasing the concentration of whey powder and the number of treatments significantly improved the pulp and paper characteristics, thus, using the treatment with 2% whey powder twice and 0.4% whey powder once led to the best results for bagasse protection in terms of quality of the raw material, pulp and handsheets.

Paper presents the results of the experimental investigations of the pulp and paper industry’ wood waste processing method into high-quality synthesis gas. The main characteristics of feedstock (moisture and ash content, elemental composition, higher and lower heating values, volatile matter and fixed carbon content) and synthesis gas (yield, chemical composition, heating value and tar content) in dependence of the processing parameters are described. Processing is carried out by the two-stage pyrolytic conversion method, combining pyrolysis and subsequent high-temperature cracking of volatiles in the charcoal fixed bed. The principal scheme and results of the thermotechnical characteristics calculation of the pilot plant capacity of 300 kg/h of raw material (mechanical mixture of wood chips and bark with a moisture content of 48 %) are presented. The obtained results confirm the high efficiency of the method as applied to the processing of this type of waste.

Price Trends

In the last decade the prices of wood in Slovakia were affected by the global economic crisis, rising intensity and extent of incidental felling and specific market conditions in SR. This paper analyses the shares of selected raw wood assortments supplies for the pulp and paper industry in Slovakia, the Czech Republic, Austria and Germany for the period 2008-2013. We also analyse the price trends of raw-wood assortments of the III.C class spruce, fir and beech saw-logs, pulpwood and firewood in selected countries of Austria, the Czech Republic and Slovakia. The analysed period represented the last 7 years (from 2008 - April 2015). The last part is devoted to evaluation of the potential of these assortments as a source of raw material for pulp and paper industry.
