FIELD: woodworking. SUBSTANCE: press-composition contains particles of lignocellulose material containing lignin, cellulose, hemicellulose, and free sugars forming on consecutive treatment with hydrolyzing agents, in particular sulfuric or phosphoric acid, steam, and modifying agent: iron sulfate or zinc chloride, or copper chloride. Implementation of invention is achieved by that modifying agent is introduced into wood pulp steamed at 170-190 C. Board material is fabricated by high pressing of composition at 100- 120 C. EFFECT: reduced toxicity of boards characterized by good physicochemical properties. 3 cl, 5 tbl _
