Technological properties and uses of wood from Paulownia fortunei and its hybrids: a systematic review Camila Alves Corrêa, Alexsandro Bayestorff da Cunha, Samuel da Silva Santos, Tarcisio Francisco de Camargo, Taíse Mariano Rodrigues, et al. European Journal of Wood and Wood Products, 2026 Paulownia fortunei , the species native to China, stands out as one of the fastest-growing trees in the world. Due to this characteristic and the wide variety of uses of its wood, its plantations, already significant in Asian countries, are expanding to other regions. The quality of the wood, determined by its anatomical, chemical, physical, and mechanical properties, is fundamental to guiding its applications. Furthermore, its performance in processing operations, such as sawing, drying, and machining, is crucial for industrial use. This systematic review aimed to gather and analyze available studies on the properties of P. fortunei wood and its hybrids, its behavior in industrial processes, and its potential applications, with an emphasis on higher value-added solid products. The methodology was structured in three stages: (i) searching the selected databases based on the defined research questions and keywords; (ii) screening articles according to inclusion and exclusion criteria; and (iii) systematic analysis of eligible studies and synthesis of their main results. The studies analyzed demonstrate that P. fortunei wood has broad application potential, varying according to the cutting age, and that its low density is a central characteristic, favoring uses that demand lightness. However, a scarcity of research focused on processing stages was observed, especially sawing, machining, gluing, and the production of solid wood panels.
Influence of artificial weathering on the colour of wood Eucalyptus benthamii Maiden et Cambage treated with different finishing products Alexsandro Bayestorff da Cunha, Camila Alves Corrêa, Ângela Silva dos Santos, Helena Cristina Vieira, Martha Andreia Brand, et al. Holzforschung, 2025 Eucalyptus benthamii has been identified as one of the main forest species for planting in the southern region of Brazil due to its resistance to low temperatures. Current studies with the species are restricted to forestry and the processing of wood from short-rotation plantations. However, the greatest added value occurs in processing, where the application of paints and varnishes can change the characteristics of the wood. The objective of the study was to evaluate the colour changes of E. benthamii wood, coming from long rotation plantations, subjected to artificial weathering, with two finishing products. The surfaces of the pieces were treated with marine varnish and power stain and subjected to three cycles in the weathering chamber (240 h, 480 h, and 720 h), following the standard ASTM G154 (2006. Standard practice for operating fluorescent light apparatus for UV exposure of nonmetallic materials (ASTM G154-06)). To measure colourimetric parameters, a Konica Minolta colourimeter (model CR-400) was used. The artificial weathering process caused darkening of the wood and a very appreciable variation in the surface colour after 240 h. After 720 h, all samples showed a tendency towards a yellow–brownish tone, with a standardisation in colour after accelerated ageing. This characteristic is interesting for marketing, considering consumers’ preference for the natural colour of wood.
Energy viability of industrial drying of wood chips Flávio José Simioni, Martha Andreia Brand, Debora Cristina Bianchini Biofuels, 2023 Moisture content (MC) is one of the physical properties of wood that most influences its energy efficiency as fuel. The aim of the present study was to analyze the viability of drying pine wood chips in comparison to undried chips, considering the balance of the energy content as the primary evaluation parameter. We also investigated whether the increase in the energy content of dried wood chips exceeds the energy required for the drying process, demonstrating energy viability. The base scenario was created using data from an industry that performs wood chip drying in a rotary dryer that reduces the MC by 15%. Based on the baseline scenario data, two new scenarios were estimated to represent variations in energy consumption to reproduce the same drying process, taking into account different combinations of MC in the input and output chips. The results showed that drying increased the energy content of wood chips by 44.96% (from 7,194 MJ.kg−1 to 10,429 MJ.kg−1). However, the energy balance of the drying process was negative in all scenarios evaluated, demonstrating that the energy expenditure required to dry wood chips exceeded the increase in energy content resulting from the reduction in MC under the conditions evaluated.
Influence of coating on the properties of non-structural plywood for outdoor use submitted to accelerated weather chamber Sandiane Carla Krefta, Alexsandro Bayestorff da Cunha, Martha Andreia Brand Scientia Forestalis Forest Sciences, 2022 Plywood panels are widely used in civil construction as forms for concrete, being produced, for the most part, by veneers of Pinus spp. and adhesive based on phenol formaldehyde resin. However, after several reuses, the panels tend to lose their original strength and stiffness characteristics due to continuous exposure to weather, water from the concrete composition and sunlight. The objective of the study was to evaluate the influence of coatings on the technological properties of non-structural plywood for outdoor use of Pinus spp., after exposure to adverse conditions of radiation, precipitation and condensation in an accelerated aging chamber. Twenty 18 mm thick commercial panels were used, divided into 5 groups according to the surface: (i) uncoated (control), (ii) oil, (iii) melamine resin, (iv) melamine film and, (v) tego film. From each group, 80 specimens were removed, of which each subgroup of 20 was subjected to 0, 10, 30 and 50 cycles of radiation, precipitation and condensation in an accelerated aging chamber, according to the procedures described in ASTM G154 (2006). After completion of the cycles, the determination of density, moisture content, strength and stiffness to static bending, and strength in bonding line shear was performed. Data were evaluated in a multifactorial way in parametric statistics through analysis of variance and Tukey's test at 95% probability of success, considering 5 factors (coatings) and four levels (0, 10, 30 and 50 cycles). The results demonstrated thar the panels of all treatments met the parameters recommended by the Brazilian Association of Mechanically Processed Wood (ABIMCI) up to 50 cycles, that is, the coatings applied and the exposure time to radiation, precipitation and condensation variables did not adversely affect the panels in terms of strength and stiffness.
