End-of-Life Logistics: DPP-Driven Sorting, Recycling, and Reverse Supply Chains

The DPP transforms end-of-life logistics by providing a digital blueprint for sorting and recycling. When a garment enters a collection point, a scanner reads the DPP via QR or RFID, instantly retrieving material composition, disassembly steps, and recyclability score. This data feeds into automated sorting systems that use NIR spectroscopy and robotic arms to separate items by fiber type, color, and condition. For example, a 100% cotton shirt with a DPP indicating it is free of hazardous chemicals can be routed directly to a mechanical recycler, while a blended fabric might go to chemical recycling.

[!IMPORTANT] Reverse logistics networks must be redesigned to handle DPP data flow. Each collection point needs a digital infrastructure to read and transmit DPP data to a central platform that optimizes routing. For instance, a garment with a high durability score might be routed to a resale partner, while a low-scoring item goes to recycling. The table below outlines sorting decisions based on DPP attributes:

To close the loop, recyclers can use DPP data to track the quality of recycled fibers. For example, a chemical recycler producing regenerated polyester can record the output’s properties (viscosity, color) and update the DPP of the new product. This creates a circular data flow that supports claims of ‘recycled content’ and ‘fully circular’ products. The EU’s proposed ‘Digital Product Passport for Recycled Content’ would require this data to be standardized and auditable.
