What are the typical sources of post-consumer and post-industrial waste used in RPA production?

Recycled Polyamide (RPA) stands as a beacon of sustainability in the realm of polymers, offering a solution to the environmental challenges posed by plastic waste. One of the key aspects of RPA production is the utilization of post-consumer and post-industrial waste. 
Post-Consumer Waste (PCW) Sources:
Post-consumer waste refers to discarded materials that have served their intended purpose and are now ready for recycling. In the context of RPA production, PCW sources include a wide array of nylon-based products that have reached the end of their lifecycle. These products encompass:
Textiles: This category includes clothing items, carpets, and other fabric-based products made from nylon or polyamide materials.
Automotive Parts: Components such as car bumpers, interior trimmings, and under-the-hood parts made from polyamide contribute significantly to PCW in RPA production.
Industrial Equipment: Machinery and equipment in various industries contain polyamide components that can be reclaimed for recycling.
Household Items: Everyday items like plastic containers, kitchenware, electronic device casings, and packaging materials constitute a substantial portion of post-consumer polyamide waste. Post-Industrial Waste (PIW) Sources:
On the other hand, post-industrial waste originates from manufacturing processes and industrial operations. These sources play a vital role in supplying clean and high-quality polyamide waste for Recycled Polyamide production. PIW sources include:
Manufacturing Scrap: During the production of nylon products, offcuts, trimmings, and rejects are generated, forming a significant portion of post-industrial waste.
Textile Industry: Textile mills and manufacturers contribute PIW through the trimming and excess materials produced during the fabrication of nylon fabrics and garments.
Industrial Excess: Various industries generate surplus polyamide materials that can be repurposed, such as packaging companies, construction firms, and consumer goods manufacturers.
Recycling Process:
Once collected, post-consumer and post-industrial waste undergo a meticulous recycling process to extract and refine the polyamide components. This process may involve:
Sorting: Waste materials are sorted based on polymer type, color, and contaminants to ensure a consistent and high-quality feedstock.
Cleaning: Cleaning processes remove impurities, dirt, and residues from the waste materials, preparing them for the next stages.
Shredding/Melting: The sorted and cleaned waste is either shredded into small pieces or melted down to form pellets or flakes.
Extrusion: Through extrusion, the polyamide material is reformed into usable granules or filaments suitable for manufacturing new products.
Chemical Treatment (Optional): In some cases, chemical recycling methods such as depolymerization may be employed to break down polyamide into its original monomers for further refinement.
