The authors reviewed recent progress of environmentally-friendly plywood and focused on the modification of current adhesives used in plywood.There were three important methods used to reduce the emissions of formaldehyde,including modification of traditional formaldehyde-based adhesives,application of biomass-based adhesives and thermo-plastic adhesives as well as pretreatment of veneer.Based on the analysis on these processing methods,the development trend and research directions of the environmentally-friendly plywood were also discussed.
