On the other hand, a bigger effort should be put into carbon capture and storage (CCS) activity, especially in the case of oil-based plastics, to extend their life in the products. The aim of the research was to use waste high-density polyethylene (HDPE) in MDF panels and determine their selected properties, including modulus of elasticity in bending, bending strength, internal bond, thickness swelling, water absorption, screw withdrawal resistance, density profile when referred to the fraction of used HDPE.The panels were created in laboratory conditions with a 50% weight content of HDPE particles of different fractions (<1 mm, <2 mm, <4 mm, and a mixed fraction containing 25% of each fraction and unsorted waste). The results show that the highest strength and modulus of elasticity were obtained for panels with plastic fractions below 1 mm. This fraction also achieved the lowest results for water absorption and thickness swelling. The fraction of the used plastic has no significant effect on screw withdrawal resistance. The negative impact of using larger fractions in the board is noticeable, however, for the mixed fraction, the results are similar to the finest fraction in terms of the internal bond, thickness swelling, and water absorption. The addition of HDPE can have a beneficial effect on the parameters of MDF panels. It is possible to create fibreboards from wasted plastic, store carbon dioxide in them, and upcycle them. In the discussed panels, the only binder for wood fibres was HDPE, so panels should not emit formaldehyde from the binder.","PeriodicalId":8205,"journal":{"name":"Annals of Warsaw University of Life Sciences - SGGW.

Delamination is one of the most common defects in the processing of wood-based materials. It has a huge impact on the quality of the final product. In order to determine the delamination indicators in a simple and reliable way, the automatic image processing method can be used (Śmietańska et al. 2020). Bator and Śmietańska (2019) proposed the special algorithm to estimate the straight line representing a milling edge. However, this algorithm is quite complicated. The aim of this article is to check whether the aforementioned (complicated) algorithmic way can be replaced by a much simpler idea – the precise manual positioning of the scanned sample on the scanner (using very simple device installed on the scanner). The special experimental research was carried out to compare the effectiveness of the two different methods. The straight line which represents the rebate edge identified by Bator and Śmietańska (2019) algorithm was usually accurate to 1 pixel (0.02 mm). The analogue line based on the assumption that the scanned samples were perfectly positioned on the scanner only sometimes fit just as well. At worst, the distance between these lines is 0.2 mm. Usually the distance did not exceed 0.16 mm but was significant and quite random. There was no statistically significant correlation between this parameter (Dmax) and tool condition (VB). It means that sample were not perfect positioned. They were placed more or less in the same position because of imperfect stiffness of the frame installed on the scanner and human errors.","PeriodicalId":8205,"journal":{"name":"Annals of Warsaw University of Life Sciences - SGGW.

Fillers play a crucial role in the production of plywood glues, providing enhanced performance and stability to the end product. Plywood, being a composite material, requires fillers to improve its mechanical properties, adhesion, and overall quality. One common filler used in plywood glues is calcium carbonate. It acts as a bulking agent, increasing the volume and density of the adhesive mixture while reducing production costs. Calcium carbonate also enhances the glue's viscosity, ensuring proper bonding and uniform application during the plywood manufacturing process. Another widely used filler is rye or wheat flour, which consists of finely ground grains. The flour not only improves the adhesive's viscosity but also contributes to the overall strength and stability of the plywood. It helps to prevent warping and enhances dimensional stability, making the final product more durable. Additionally, other fillers like talc or clay minerals may be incorporated into the glues to improve their adhesive properties and increase moisture resistance. Chestnut starch is a type of vegetable flour made by grinding edible chestnuts into a powder. It has a different texture and properties than traditional wheat or rye flour. When used as a binder filler in plywood technology, it can be biodegradable and environment-friendly. In the study, there were produced five types of plywood with 0, 1, 5, 10, and 20 parts by weight chestnut flour and one reference. All samples were produced in laboratory conditions and the selected mechanical and physical properties of the produced boards were studied. The mechanical properties of the boards increased with the addition of chestnut flour. In some tests, the results even met the highest requirements of European standards for plywood. According to this finding, a well-chosen addition of chestnut flour could be positively considered in plywood production.","PeriodicalId":8205,"journal":{"name":"Annals of Warsaw University of Life Sciences - SGGW.

The adhesives used as binders in the boards are not biodegradable, and their formaldehyde is toxic. Nowadays it is very important to take care of the environment. There are a lot of biodegradable products that as well as the current board binders can meet good mechanical and physical properties and at the same time not harm the environment. Therefore in this project, the study aimed to investigate the possibility of producing dry-formed fibreboards usingrice starch as a binder. The research involved the production of boards with a mass proportion of rice starch 0%, 10%, 12%, 15%, and 20% (when referred to as totally dry wood fibre mass) and to study of their selected physical and mechanical properties. The results proved that rice starch can be used as a binding agent if we choose the right amount of starch so that it can improve some mechanical and physical properties. Very good properties came out for the determination of modulus of elasticity in bending and of bending strength and for screw withdrawal resistance with a high rice binder content, but on the other hand for internal bonds, the high rice content reduced the properties. For some studies, rice flour improved properties but not enough to comply with standards as was the case with the swelling of the thickness.","PeriodicalId":8205,"journal":{"name":"Annals of Warsaw University of Life Sciences - SGGW.

Every year, care cuts are carried out in the orchards, which result in a significant amount of waste. This waste is a valuable source of lignocellulosic material for particleboards production. As part of this study, the influence of the share of waste apple wood on the susceptibility to drilling of particleboards was investigated. Three-layer particle boards with share of lignocellulosic waste biomass from apple orchards (0%, 25%, 50% and 75%) and density level at 650 kg/m3and 550 kg/m3 were made. The particleboards were examined for the axial force and torque that occurs during drilling. The highest value of the axial force during drilling was notice for particleboard without apple wood and a density of 650 kg/m3. While the lowest axial force during drilling was recorded for particleboard with 50% share of apple wood and density of 550 kg/m3. The obtained results allow to conclude that density of the produced particleboards and the share of apple wood waste have a statistically significant effect on the axial force during drilling. While the share of apple wood do not statistically affect the torque during drilling. In the case of the pressing unit pressure used in the particleboards production process, no statistically significant influence on the axial force and torque during drilling was found.","PeriodicalId":8205,"journal":{"name":"Annals of Warsaw University of Life Sciences - SGGW.
