Abstract: A method of separating constituent layers from a paper-plastic laminate material includes disposing a sheet of a paper-plastic laminate material on a first surface. The paper-plastic laminate material includes a paper layer on a first side and a plastic layer on a second side. The method also includes moving an abrasive second surface over the paper layer on the first side to contact the paper layer and separate portions of the paper layer from the plastic layer. The method further includes collecting the separated portions of the paper layer and providing the separated portions of the paper layer as input to a paper recycling process, and collecting the plastic layer and providing the plastic layer as input to a plastic recycling process. The method may help increase recycling rates of paper and plastic, reduce raw material harvesting, reduce pollution and habitat destruction, and improve the quality of recycled material.
