Abstract

Recycling of laminate flooring based on a separation of the panels into particles which are connected with a binder and formed to a new sheet shaped material. A building panel includes a surface layer and a wood fiber based core, and the wood fiber based core includes aluminium oxide particles.

Claims (24)

1. A method to recycle laminate floor panels including a wood fiber based core, a decorative surface layer that includes a thermosetting resin and aluminium oxide, the method comprises:

a) mechanical cutting of the panel into particles;

b) mixing said particles with a binder; and

c) pressing the mixed particles and binder and thereby forming a sheet shaped material,

wherein the method comprises mixing said particles with a melamine formaldehyde resin.

2. A method to recycle laminate floor panels including a wood fiber based core, a decorative surface layer that includes a thermosetting resin and aluminium oxide, the method comprises:

a) mechanical cutting of the panel into particles;

b) mixing said particles with a binder; and

c) pressing the mixed particles and binder and thereby forming a sheet shaped material,

wherein the pressing is made under heat,

wherein the method comprises mixing said particles with a melamine formaldehyde resin.

3. A method to recycle laminate floor panels including a wood fiber based core, a decorative surface layer that includes a thermosetting resin and aluminium oxide, the method comprises:

a) mechanical cutting of the panel into particles;

b) mixing said particles with a binder; and

c) pressing the mixed particles and binder and thereby forming a sheet shaped material,

wherein the method further comprises separating particles essentially into a first set of particles comprising substantially wood fibers and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.

4. A method to recycle laminate floor panels including a wood fiber based core, a decorative surface layer that includes a thermosetting resin and aluminium oxide, the method comprises:

a) mechanical cutting of the panel into particles;

b) mixing said particles with a binder; and

c) pressing the mixed particles and binder and thereby forming a sheet shaped material,

wherein the pressing is made under heat,

wherein the method further comprises separating particles essentially into a first set of particles comprising substantially wood fibers and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.

5. The method as claimed in claim 1 , wherein the method further comprises separating particles essentially into a first set of particles comprising substantially wood fibers and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.

6. The method as claimed in claim 2 , wherein the method further comprises separating particles essentially into a first set of particles comprising substantially wood fibers and a second set of particles comprising substantially melamine before mixing at least the first set of elements with a binder.
