METHOD AND DEVICE (SYSTEM) FOR PRODUCING A MATERIAL PANEL, MATERIAL PANEL, AND USE OF A MATERIAL PANEL

The invention relates to a method for producing a material panel (10), having at least one layer (15, 16, 17) having at least one natural fibre component (F), at least one of the at least one layer (15, 16, 17) comprising a useful product (11) which is produced from a raw material (14) obtained from a preformed material panel (10′). The method has at least one forming process part (BP) and an auxiliary process part (UP) and comprises at least the following steps: i) mechanically contacting pre-crushing of the preformed CD material panel (10′) into raw material (14), ii) decomposition of the raw material, under the action of a pressure shock wave (W) having a pulse duration (ID) and a pulse frequency (IF), into at least a first component (K1) and a second component (K2), at least one of the components (K1, K2) as useful product (11) being suitable for use in the at least one forming process part (BP) for the material panel (10) to be produced, iii) separating at least the second component (K2) and the first component (K1), iv) at least proportionately feeding the at least one component (K1, K2), which is suitable for the forming process part (BP) for the material panel (10), into the forming process part (BP) of the further production process. The invention further relates to an apparatus for producing a material panel having at least one laver, a material panel, and the use of a material panel.
