Реферат: The present invention relates to a method for producing wood materials from lignocellulose-containing crushed products, in particular for producing wooden insulating panels or OSB boards, wherein in order to decrease or reduce the emission of volatile organic compounds (VOC) and, if relevant, very volatile organic compounds (VVOC), including terpenes, acids and aldehydes, said wood materials are treated with a combination of additives during production. According to the invention, the treatment is carried out with a first component made of porous carbon and a second component, a hydrogen sulphite salt. The invention further relates to wood materials that can be obtained using the method according to the invention, having reduced emissions of VOCs, including terpenes, acids and aldehydes. Finally the present invention relates to the use of a combination of additives, formed by a first component with a porous carbon and a second component made of hydrogen sulphide salt, for decreasing or reducing the emission of VOCs from wood materials during or after production thereof from lignocellulose-containing crushed products.
