Provided are a recycling method which can easily separate a plastic film laminate into individual single layers and recover the layers, a recycled plastic processing material which can be processed into a high-quality recycled plastic from a plastic film laminate, and a method for producing the recycled plastic processing material. A recycling method for a laminate, winch includes crushing a plastic film laminate having at least two layers in water or a cleaning agent simultaneously with conducting pumping so that the crushed material obtained by crushing the laminate has a surface roughness of 0.7 μm or more.

A process for producing a particulate recyclate from quartz composite by comminuting quartz composite moldings composed of a polymer matrix with inorganic and/or organic filler particles embedded therein, wherein precomminuted pieces of molding are comminuted in a hammer mill to form particles that form the recyclate.

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.
