To eliminate toxic formaldehyde from wood-based panels, a new formaldehyde-free wood adhesive (named OL/PEI adhesive) was synthesized by reaction of oxidized lignin (OL) and polyethylenimine (PEI) in the presence sodium periodate. The curing mechanism clarified Fourier transform infrared spectroscopy (FTIR) solid-state cross-polarization magic angle spinning carbon-13 nuclear magnetic resonance...

Cement bonded particleboards were manufactured from hornbeam (Carpinus betulus L.) wood particles. Hydration tests were carried out to determine the inhibitory index in order to characterise wood-cement compatibility. The results revealed that the mixture of hornbeam -cement can be classifi ed as moderate inhibition. Two wood: cement ratios were applied in this study, namely 1:3 and 1:4, for th...

Particleboard is not entirely a wood replacement but particular material with its properties, making it more effective at different times than heavy or solid wood. The world’s biggest concern environmental problems formaldehyde as particulate board binder that can lead to human carcinogenic agents. A cradle-to-gate life cycle assessment (LCA) of particleboard production was performed using open...
