Unlike previous research that primarily focused on durability, this work evaluates the effects of these bio-based treatments on leaching resistance, internal bond strength (IB), bending properties, water absorption, thickness swelling, and vertical density profile (VDP). The results demonstrate significant improvements over commercially available OSB, particularly in mechanical performance. Post-leaching, both treatments exhibited superior IB, with tannin-treated panels achieving the highest IB value (0.27 MPa). The bending analysis revealed that caffeine-treated panels that were not subjected to leaching achieved the highest modulus of rupture (MOR, 62.54 MPa) and modulus of elasticity (MOE, 10.36 GPa). Both treatments retained significantly higher MOR and MOE values post-leaching compared to the industrial reference and untreated panels. Water absorption and thickness swelling were comparable among tannin-treated, caffeine-treated, and untreated panels but were significantly lower than those of the industrial reference, which was included for general benchmarking purposes alongside the laboratory-made control. VDP analysis showed caffeine-treated panels had the lowest density prior to leaching, whereas tannin-treated panels maintained the highest density after leaching. These findings highlight tannin and caffeine as effective and scalable treatments, providing a sustainable alternative as functional additives for industrial engineered wood product manufacturing.</p>\u0000 </div>","PeriodicalId":550,"journal":{"name":"European Journal of Wood and Wood Products","volume":"83 5","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00107-025-02334-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The accuracy of a drilling resistance tool for predicting wood density may be affected by needle (drill) wear, and there is limited information regarding the wear behaviour of drill bits in wood resistance drilling. It is unknown when changes in needle sharpness and diameter become critical for quantifying wood density. To measure the effect of Resi needle wear, an IML Resi PD 500 was used to obtain cross-sectional traces of Southern Pine (<i>Pinus elliottii</i> var. <i>elliottii</i> (Engelm) × <i>Pinus caribaea</i> var. <i>hondurensis</i> (Sénéclauze)) average outerwood density: 519 kg/m³ and Spotted Gum (<i>Corymbia citriodora</i> subsp. <i>variegata</i> (F.

Spotted Gum was tested with a feed speed of 70 cm/min at 5000 rpm. A new needle was used for each setting. The effect of needle wear was tested after 0, 100, 200, 300, 400, 500, and 600 m of drilling depth. There was no effect on drilling resistance values up to 600 m of drilling length with feed speed 200 cm/min and 3500 rpm settings for Southern Pine. This would result in 2000 drilling measurements of 30 cm diameter trees. With alternative setting for Southern Pine with a setting of 100 cm/min feed speed and 5000 rpm, the increase in amplitudes was not significant until 300 m of drilling, after which, at 400 m, the amplitude increased by 2% (9.8 kg/m<sup>3</sup>), and after 600 m, the amplitude increased by 3.1% (15.2 kg/m<sup>3</sup>). For the hardwood Spotted Gum, the amplitude decreased by 0.9% (2.3 kg/m<sup>3</sup>) after 100 m, and after 300 m, the amplitude decreased by 3.3% (8.2 kg/m<sup>3</sup>).

In total 2457 specimens were tested in mechanical strength and around 1000 for dimensions of micro and macrostructural wood elements. In the case of the most important parameter – the wood density, no significant differences were found between values observed in standard forest land (0.722 g/cm<sup>3</sup>) and afforested farmland (0.701 g/cm<sup>3</sup>). Land use did not significantly influence MOR nor MOE. However, higher values for these parameters were observed on forest land. The annual ring width was significantly wider on trees that grew on former agricultural land. The high variability with significant differences was obtained within the dimensions of vessels and fibers. The presented results have confirmed that European beech species is highly suitable for former agricultural land afforestation with high-quality wood production.

Willow (<i>Salix</i> sp.), a short-rotation hardwood species, is an interesting feedstock for such applications. It can represent an alternative raw material for non-sustainable resources, long-rotation trees, and agricultural biological materials. This research aimed to characterize the chemical properties of different wood tissues of willow and to develop a nondestructive method for their prediction. Wood, bark, and twig samples were sampled from six willow clones (Alberta, Canada). Extractives, cellulose, hemicellulose, and lignin contents were measured in sampled tissues by destructive chemical analysis tests using TAPPI standard test methods. The surface chemistry of the samples was analyzed by near-infrared spectroscopy. Partial least squares regression models were developed for quantitatively predicting wood chemical components. The coefficients of determination (R² calibration, R² cross-validation, and R² prediction) ranged from 0.66 to 0.99 for extractives, lignin, cellulose, and hemicelluloses. Carbohydrates (glucose, xylose, arabinose, and mannose) ranged between 0.98 and 0.99, demonstrating excellent predictive capability for these components. These results confirm the applicability of the developed models to predict the chemical properties of willow biomass. Furthermore, the prediction models apply to all investigated tissues, emphasizing consistency. These results provide the possibility to characterize the chemical properties of willow biomass using easily implemented, cost-effective, nondestructive, and rapid NIR equipment.</p></div>","PeriodicalId":550,"journal":{"name":"European Journal of Wood and Wood Products","volume":"83 5","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145028286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
