Abstract
A process for production of wood-base materials from lignocellulosic comminution product is disclosed. The wood-base materials are treated with at least one additive in the course of their production to reduce or diminish the emission of volatile organic compounds (VOCs) and, optionally, very volatile organic compounds (VVOCs), in particular terpenes and acids. The treatment is effected with one additive, being a porous carbon, like activated carbon. In another aspect, the present application is directed to the use of porous carbon, in particular, activated carbon, to reduce or diminish the emission of VOC, and optionally, VVOC, to reduce or diminish the emission of terpene and acids and aldehydes. Also, wood-base materials which are obtainable with the process or wood-based materials produced by using the additives mentioned above and which have reduced emission of VOCs, in particular terpenes and acids but also aldehydes are disclosed.
