The most significant reduction in formaldehyde emission (up to 42.3%) of plywood panels and the achievement of high bonding strength was observed for UF/BF samples with a bark concentration of 5 wt%. Panels with UF/BF formulations at a bark content of 1 wt%, 3 wt%, and 5 wt% had higher wet bonding strengths than those made with the control sample. It was confirmed that the bark absorbs formaldehyde and the solution with 5 wt% of bark absorbed the most formaldehyde. might be interested in an EndNote class or an exhibit on Harry Potter.
