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.

The evident shortage of wood as a raw material has become a limiting factor in the pulp and paper industry which is the greatest consumer of wood in Europe. The situation in our country is similar. During the few past years, the production of poplar and willow pulpwood was 220.000 m3 per year, which is insufficient for the planned increase in the production of sulphate pulp (175.000 tons till 2005). This paper deals with the aspects of the more efficient yield of raw material, based on the significantly higher yield of CTMP fibres, as well as with the significance of the lower adverse effect on the environment. It also analyses the conditions of production and the quality of the obtained fibres, as a possible substitute for chemical pulp and secondary fibres in papers of different quality. The main reasons for the production and use of CTMP fibres in our country are reported.

Recent advances made in the reuse of pulp and paper industry sludges in hardboard production are explained. Data obtained from pilot and full-scale plants using primary sludge of a pulp and paper industry as an additive in the production of hardboard is presented. An economic analysis of the reuse of pulp and paper primary sludge in hardboard manufacturing is given. The quality of the hardboard produced is tested and compared with the qualities of the hardboard produced by the same plant before the addition of primary sludge. The hardboard with primary sludge additive has been used in Turkey for about a year in the manufacturing of office and home furniture. The results are very satisfactory when the primary sludge is used at 1/4 ratio.

Human resources are recognized as one of the key factors of success. The generic skills significantly determine the quality of those resources. The paper aims at identifying a set of generic skills which are the most expected by managers. The discussion is based on the results of a survey which was carried out among the representatives of the pulp and paper industry. The responses came from 34 managers (including 17 top managers) from 17 different countries. The 10 most significant (most wanted by the managers) generic skills were identified as: (1) teamwork, (2) flexibility, (3) initiative, (4) leadership, (5) drive, (6) analyzing and investigating, (7) global skills, (8) planning and organizing, (9) verbal communication and (10) computer skills.

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.
