This study determined the effects of surface veneering (V), edge banding (E), and handle and hinge holing on formaldehyde emission (FE) for standard particleboard (PB) and medium-density fiberboard (MDF). Thirty test samples were prepared from PB and MDF. Each sample was pressed by 0.6-mm beech veneer and edged with 2-mm beech veneers. In the samples, two handle holes were drilled with 18-mm depth and 5-mm diameter, and two hinge holes were drilled with 15-mm depth and 30-mm diameter. FE was measured in accordance with Turkish standards by a MultiRAE multiple gas analyzer. A significant decrease from 93 to 80 percent for PBs and from 72 to 22 percent for MDFs was detected when compared with the control samples. V and E of boards (PB/MDF + V + E) significantly reduced FE from 1.1078 to 0.0733 parts per million (ppm) (93%) for PB and from 0.2311 to 0.0667 ppm (72%) for MDF. Drilling holes for hinges and handles (H) on the surfaces of boards slightly increased FE from 0.0733 to 0.0789 ppm for PB and from 0.0644 to 0.0789 ppm for MDF. Regarding distance to E1 (0.10 ppm), unprocessed control samples and samples of PB + V and MDF + V yielded results higher than the limits of E1. In conclusion, V and E significantly reduced FE, whereas H slightly increased FE. The need for a way to reduce FE to accepted levels is of great concern for the Turkish furniture industry.
