Method and assembly for manufacturing a board element comprising a recycled material

A method for manufacturing a floorboard element comprising an at least partially recycled board layer, the method comprising:

• providing a pre-processed material from at least one weight-reduced preformed board element, wherein the pre-processed material comprises a thermoplastic material;
• providing a virgin material comprising a thermoplastic material;
• applying the pre-processed and virgin materials on a carrier by scattering;
• applying heat and pressure to the pre-processed material and the virgin material on the carrier in a double-belt press to form said board layer;
• and
• forming a floorboard element comprising the board layer,
• the method further comprising mixing the pre-processed material and the virgin material to provide a mixture and applying the heat and pressure to the mixture in said double-belt press,
• wherein, during the providing of the pre-processed material, the pre-processed material is more than 20 wt % of a total amount of material that is provided,
• wherein a degree of inorganic filler exceeds 60 wt % of a total weight in any or both of the pre-processed and the virgin materials,
• wherein the pre-processed material and the virgin material comprise PVC, and
• wherein the thermoplastic material is 12-55 wt % of a total weight for one or both of the pre-processed and the virgin materials.
