Postindustrial or pre-consumer textile waste is generated in the fabric and apparel manufacturing processes, from weaving, spinning, or cut-and-sew operations. Discards can include short cotton or wool fibers, yarn waste, trimmings or surplus. In the United States alone, 120,000 tons of postindustrial textile waste is produced annually. In order to address the negative environmental impacts, manufacturers are employing more efficient production processes to reduce waste.
