FIELD: wood wastes processing.
SUBSTANCE: invention relates to technologies for processing wastes from logging and wood processing operations, in particular to methods for producing semi-finished products out of wood fiber. A method of producing a wood-fiber semi-finished products out of wood fiber obtained from wood chips that are produced from branches, tops and twigs includes pretreatment of the wood chips with a 15-17% solution of acetic acid, grinding the processed wood chips in a device to grind chips in an aerodynamic environment, pressing the resulting wood-fiber semi-finished product and its further packaging by a vacuum packer.
EFFECT: technical result of the invention is the development of a simple and cheap method for obtaining a semi-finished wood-fiber product from logging slash in the form of branches, tops and branches processed into wood chips.
