Waste Lump refers to the solid by-product or rejected material generated during the production and processing of plastics, polymers, and textile fibers. It is usually formed due to process variations, off-grade batches, or excess heat during manufacturing, resulting in irregular hardened lumps of material. Waste lumps are commonly collected from polyester, PET, nylon, and other polymer-based industries, where they serve as a valuable secondary raw material for recycling. These materials can be reprocessed into granules or chips, which are then used for manufacturing low-grade plastic products, textile fibers, sheets, or molded components. Proper handling and recycling of waste lumps not only reduce industrial waste but also support cost-effective production and sustainability practices.
