The disclosure relates to a method for producing a wood-based material panel with the steps: producing a raw wood-based material panel which includes a first lateral surface and a second lateral surface that runs parallel to the first lateral surface, and edge surfaces that connect the lateral surfaces to each other; applying a liquid containing a flame retardant at least to the first lateral surface; and applying a negative pressure to the second lateral surface so that the liquid containing the flame retardant is sucked into a peripheral zone of the raw wood-based material panel, and/or applying an overpressure to the first lateral surface so that the liquid containing the flame retardant is pressed into a peripheral zone of the raw wood-based material panel, resulting in the wood-based material panel.

The present invention relates to a process for the manufacture of a lignocellulosic fibre-based composite material comprising the steps of: providing a lignocellulosic material and providing formulated plant seed pellets (S11), the formulated plant seed pellets comprising a plant seed material and at least one additive; defibrating the lignocellulosic material and defibrating the formulated plant seed pellets, and obtaining a fibrous mix (S1) comprising the defibrated lignocellulosic material and the defibrated formulated plant seed pellets; blending the fibrous mix with a resin (S2) to form a composite mixture; and curing (S3) the composite mixture, thereby forming the lignocellulosic fibre-based composite material.
A preferred application of this process is the manufacture of fibreboards, such as MDF.

A method for making cellulose-based fire resistant insulation. The insulation includes a plurality of superstructures that establish voids in the insulation. The insulation may be blown in place while the superstructures maintain the void portion of the insulation. The insulation is made with fiber residuals, either alone or in combination with other cellulosic materials. The method of making the insulation includes the steps of treating the cellulosic materials with a fire retardancy chemical or chemicals and creating bonds between the fibers to form the superstructures.
