Beschreibung
Zusammenfassung:	This invention concerns a method for manufacturing a compressed product. According to the method, a lignocellulosic material is contacted with an activating agent to produce modified lignocellulosic material containing free radicals, the modified material is formed into a layered structure, and said layer is pressed into a compressed product. According to the invention, the lignocellulosic material is contacted with the activating agent in fluffed state. L'invention concerne un procédé servant à fabriquer un produit comprimé. Ce procédé consiste à mettre en contact un matériau lignocellulosique avec un agent d'activation afin de produire un matériau lignocellulosique modifié contenant des radicaux libres, à créer une structure stratifiée au moyen de ce matériau modifié et à comprimer ladite couche afin d'obtenir un produit comprimé. D'après cette invention, on met le matériau lignocellulosique en contact avec l'agent d'activation lorsque ledit matériau est à l'état pulvérulent.
