Footwear is size-reduced through shredding and grinding, then sorted into four categories: metals, textiles, mixed synthetic materials, and synthetic rubbers and foams. Metals are smelted for secondary manufacturing (e.g., sheeting, ingots, bar stock), textiles are used as filler via textile recycling, mixed synthetics are further size-reduced and used as filler in extruded products like composite lumber and sheeting, and synthetic foams and rubbers are recycled into flooring applications such as sports surfaces and industrial matting.
