Abstract:This study was performed to determine the impact of VOC (formaldehyde) emission amount, in which, variety process (agglutination, varnishing, etc.) applied in furniture production sector in our country, and effect of using settings to formaldehyde emission amount; and develop to process of reducing emission. Therefore the wood-based panels (particleboard, fiberboard, plywood, chipboard, MDFlam), the laminated wood materials (oriental beech, scotchpine) and glues (Phenol-formaldehyde, Urea-formaldehyde) and cellulosic varnish processed variety furniture samples, commonly used in furniture industry, were used. In the preparation of test samples, TS 2470 and EN 326-1 standards was used. The samples were conditioned at 20±2 °C and at 65±5 % relative humidity until their weights became stable in the conditional room. The tests were realized according to the TS EN 717-1 principles in 3 different environments as the 1st environment (10 degrees temperature - 95 % humidity); 2nd environment (20 degrees temperature - 65 % humidity) and 3rd environment (40 degrees temparature - 35 % humidity). As a consequence, recording to different species in laminated wood material, the highest formaldehyde emission (450,4 ppb) was found in scotchpine, and the lowest (414,3 ppb) was found oriental beech. According to experimental outcomes, the highest value was measured in the third environment (481,9 ppb), and the lowest value was measured in the first environment (390,1 ppb). With the wood-based panels, particleboard gave the highest formaldehyde emission value in the third environment (1725 ppb), whereas the beech plywood gave the lowest formaldehyde emission value (392,5 ppb) in the first environment. Less emission was diffused with edge lining MDFlam and chipboard than open edged samples. According to these results, type of glue, varnishing in laminated wood material effects the formaldhyde emission and edge lining process in wood-based material reduces the emission. It can be also said that in places with high temperature and using wood-based material incerase formaldehyde emission
