Coniferous forests are drying out due to climate change, creating a need for alternative species. Grey poplars (Populus × canescens) are underutilized in Hungary, with about 12 million m³ reaching harvesting age by the end of 2026 and decaying due to limited industrial use. The bondability of grey poplar with structural polyurethane (PUR) and nonstructural polyvinyl acetate (PVAc) adhesives, comparing it with Scots pine (Pinus sylvestris) and beech (Fagus sylvatica) under both dry and wet conditions, in accordance with EN standards is evaluated in the study. Beech met the minimum dry tensile shear strength requirements for both adhesives, whereas grey poplar and Scots pine did not. Grey poplar bonded with PVAc showed higher dry strength than Scots pine, while Scots pine with PUR outperformed grey poplar. Despite its higher density, grey poplar heartwood exhibited lower strength than sapwood. Overall, grey poplar’s adhesive performance was comparable to Scots pine, suggesting it could serve as a viable alternative to coniferous species in both load-bearing and non-load-bearing applications. © 2026, Technical University in Zvolen.
