Abstract
A method for reusing used paper material such as paperboard cartons comprises the steps of collecting used paper material after it has been used for its original purpose, dividing the used paper material into pieces without repulping the used paper material, coating an adhesive material onto the pieces, and assembling the coated pieces together into a layer to form a structural panel, the adhesive material binding the pieces together upon curing or drying. The pieces can be long narrow strips and/or shredded pieces and/or fiberized pieces that are essentially randomly oriented in the structural panel.
Claims26
A structural panel, comprising:
- a plurality of pieces of used paper material produced by dividing the used paper material into pieces without repulping the used paper material;
- and
- adhesive material coated onto the pieces of used paper material;
- the coated pieces of used paper material being assembled together into a layer and joined to one another by the adhesive material to form a structural panel, wherein the coated pieces are respectively randomly oriented in a multitude of different orientations within the layer.
A method for making a structural panel, comprising the steps of:
- dividing used paper material into pieces without repulping the used paper material;
- coating the pieces with an adhesive material;
- and
- assembling the coated pieces together into a layer to form a structural panel, the adhesive material binding the pieces together upon curing or drying of the adhesive material, wherein the assembling step results in the coated pieces being respectively randomly oriented in a multitude of different orientations within the layer.
