Abstract
The present invention pertains to a method to enable recycling of a panel comprising as a core structural component a polysaccharide fibre based plate at least one side of which is covered with a layer of a non water soluble adhesive, the method comprising immersing the panel in an aqueous liquid at least until the polysaccharide fibre based plate has absorbed an amount of liquid that leads to detachment of the adhesive from the polysaccharide fibres and at least partial detachment of neighbouring polysaccharide fibres from each other, resulting in a mixture of at least partially individualised polysaccharide fibres and separate adhesive, and thereafter removing the adhesive from the mixture.
