  • Publication number: 20020046655
    Abstract: A method for recovering VOC and HAP emissions in the production of a lignocellulosic product is provided. The method comprises forming a mat of lignocellulosic material by bonding together and mat in a product formation press with an adhesive material to produce the lignocellulosic product. VOC and HAP emissions are produced during the formation of the lignocellulosic product in a product formation press. The VOC and HAP emissions produced are withdrawn during the formation of and lignocellulosic product prior to removal of the lignocellulosic product from the product formation press. Then, the VOC and HAP emissions which are withdrawn from the formation press are recovered without releasing same to the atmosphere.
