Abstract (en)
[origin: EP2272644A1] Volatile organic compounds and aldehydes emission reducing involves utilizing lignocellulose containing products. An additive is added in the lignocellulose reducing products to obtain a mixture. The obtained mixture is treated with ammonia to obtain a product. The product is treated with adhesives by heating to produce wood material. Volatile organic compounds and aldehydes emission reducing involves utilizing lignocellulose containing products. An additive is added in the lignocellulose reducing products to obtain a mixture, where the additive is thiosulfate of formula RS 2O 3or R2(S 2O 3). R : alkali metal or alkaline earth metal. Independent claims are also included for: (1) a wood material, which is obtained by using fiber boards and strand board; and (2) an agent for reducing emission of volatile organic compounds and aldehydes, which comprises formaldehyde and lignocellulose containing products.
