METHODS FOR CONVERTING USED PAPER MATERIAL INTO STRUCTURAL PANELS, AND STRUCTURAL PANELS MADE THEREBY

摘要

A method for reusing used paper material (20) 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 (60) 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.
