Abstract
To reduce the air pollution of large city in Japan, the air pollution control act was revised recently. The definition of volatile organic compound (VOC) and measurement of VOC concentration in factory were stated in the act. The regulation of the amount of VOC emissions from factory such as some painting and drying process were stated. Although adhesion and drying processes of wood-based material factories were not regulated, the factories have to take voluntary effort to reduce the VOC emission. Thus we investigated the VOC emission from wood-based material factories to support the voluntary effort to reduce the VOC emission. In case of the plywood factory, the VOC emissions from producing processes were included mostly the extractives of wood. With laminated veneer lumber (LVL) factory, the results of continuous measurement for VOC emission showed that VOC emission patterns were different between plywood and LVL hot press process. The amount of VOC emissions from adhesion process in overlay plywood and single layer flooring factories were very low level because of the correspondence of the sick house syndrome problem.
