The paper presents preliminary results of our studies on possible use of roasted coffee waste in the form of husks as a substitute for wood chips in three-ply particleboards glued with melamine-formaldehyde resin (MUF). We produced boards in which roasted coffee waste substituted up to 50% of wood chips. Increasing share of coffee waste caused a gradual decrease in the board bending strength and internal...
In this work the optimum resination rate of white mustard straw particles with UF resin in the production of straw particleboards was investigated. The resination rates used in this study were 10, 12 and 14%. For the selected resination rate, the possibility of reducing the density of the straw particleboards was also determined. In order to evaluate the hygienic parameters of the experimental boards,...

Non-normative method for determining acoustic insulation of board materials. The paper presents a new method for the measurement of acoustic insulation against airborne sounds in the insulation and construction board materials used in wooden and brick buildings. The primary aim of the study was to simplify the design of a test stand, and thus of individual measurements, while maintaining the confidence...
This study evaluated the applicability of particles of white mustard straw as a substitute of wood chips in the manufacture of particle boards, resinated with UF resin. The scope of work included the determination of suitability of mustard straw in the manufacture of particle boards, the manufacture of boards with different proportions of straw and the determination of their basic physico-mechanical...
