Claim 5:
6. A method comprising:
peeling a multi-layer laminate material comprising a first layer, a second layer, and a third layer disposed between the first layer and the second layer, to obtain a dual-layer sheet, the dual-layer sheet comprising the third layer on a first side and one of the first layer or the second layer on a second side;
disposing the dual-layer sheet on a first substantially flat surface such that the first layer or the second layer contacts the substantially flat surface, and the dual-layer sheet is held substantially stationary with respect to the substantially flat surface;
moving an abrasive second surface with respect to the substantially flat surface, the abrasive second surface configured to separate portions of the third layer from the first or second layer, wherein the abrasive second surface comprises multiple small ringlets configured to scrape off the third layer from the dual-layer sheet while preserving the first or second layer;
collecting the separated portions of the third layer and providing the separated portions of the third layer as input to a first recycling process configured to process material of the third layer; and
collecting the first or second layer and providing the first or second layer as input to a second recycling process configured to process material of the second layer.
