First Claim
Patent Images
1. A method to recycle floor panels comprising a wood fibre based core, a decorative surface layer comprising a thermosetting resin and aluminium oxide wherein the method comprises the steps of:
- mechanical cutting of the panel into particles;
mixing said particles with a binder; and
pressing the mixed particles and binder and thereby forming a sheet shaped material,wherein the binder is a phenol resin.
