Einführung: Waste textile recycling is an urgent issue for the global circular economy
According to the European Environment Agency’s 2025 “Progress Report on the Circular Economy of Textiles,” the EU generates approximately 5.8 million tons of waste textiles annually, of which only 22% is recycled and reused, with the majority being incinerated or landfilled. Von 2025, the EU’s Waste Framework Directive requires member states to establish independent textile sorting and collection systems. Rfid, as a digital roadmap connecting the entire lifecycle of clothing, is becoming a key technology for solving this problem.
Three Major Pain Points in Waste Textile Recycling
1.1 Low Efficiency of Manual Sorting
Traditional used clothing recycling relies on manual visual identification of materials, colors, and brands. According to data from the German Federal Environment Foundation, skilled workers can sort a maximum of 50-80 garments per hour, with an accuracy rate of only 75-85%. For recycling centers handling tens of thousands of tons annually, this constitutes a significant bottleneck in labor costs and efficiency.
1.2 Difficulty in Material Identification
Rapid identification of blended fabrics (such as cotton-polyester blends and wool blends) is a major industry challenge. While near-infrared (NIR) spectroscopy can identify some materials, its recognition rate drops significantly for dark-colored clothing, multi-layered structures, or coated fabrics. Tests conducted by the Dutch Research Centre for Circular Textiles show that NIR’s accuracy in identifying the material of black clothing is less than 60%.
1.3 Data Loss Leading to Value Loss
Information such as brand, Alter, and care history contained in waste textiles is completely lost after entering the recycling process. This makes it impossible to accurately price high-value secondhand clothing, and fiber recycling plants cannot obtain composition data to optimize their processes.
RFID Solution: Aus “Waste” Zu “Data Asset”
2.1 Technisches Prinzip: Digital Navigation Markers Embedded in Clothing
If clothing is tagged with RFID -Tags (whether washable tags or hang tags) during the production stage, then this garment carries a unique digital identity throughout its entire lifecycle from production to recycling. Key chips and standards include:
- NXP-UCODE 9: High sensitivity (-24dBm), suitable for reading in densely stacked environments
- Impinj M730: Integrated QT technology, supporting high-speed mobile reading
- Außerirdischer Higgs-9: 512-Bit-Benutzerspeicher, capable of storing material composition, Produktionsdatum, Pflegegeschichte, usw.
- ISO/IEC 18000-6C: Global UHF RFID protocol standard
- EPC Gen2v2: Supports secure commands and user memory writing
2.2 Recycling Process: Second-Level Automated Sorting
When waste textiles arrive at the recycling center, fully automated batch identification is achieved through high-speed RFID tunnel machines (wie zum Beispiel RFIDHY RecycleTunnel):
- Reading Speed: Conveyor belt speed up to 3 meters/second, single channel processing 15,000+ pieces per hour
- Identification Rate: With optimized antenna layout (Laird S9028P × Times-7 A5020 combination), the read rate is 99.8%
- The above data matching: The read EPC code instantly queries the cloud database to obtain information such as material, brand, Alter, and original price.
2.3 Grading and Sorting: Data-Driven Precise Classification
Based on RFID-read data, the system automatically directs clothing to different sorting lines:
| Sorting Category | Judgment Criteria | Destination |
| Resaleable | Marke + Zustand + Material | Second-hand Market/Export |
| Fiber Recycling | Pure Cotton/Pure Wool/Chemical Fiber | Opening and Spinning |
| Chemical Recycling | Blended/Coating | Chemical Dissolution |
| Downgraded Utilization | Severely Soiled/Damaged | Wiping Cloth/Filling Material |
| Incineration/Landfill | Non-Recyclable | Energy Recovery |
Real-World Case: The RFID Automated Sorting Revolution of a Dutch Recycler
3.1 Fallhintergrund
The Dutch textile recycler “CircleTex” (annual processing capacity of 80,000 tons) faces increasing recycling volumes and pressure from new EU regulations. In 2024, its manual sorting line processed only 120 tons per day with an accuracy rate of 82%, and the difficulty of recruiting workers continued to increase.
3.2 Lösung
In 2025, CircleTex partnered with a professional RFID-Lösung provider to launch a pilot project for RFID automated sorting:
- Front-end Data Preparation: An agreement was reached with 5 partner apparel brands to mandate the use of ISO 18000-6C compliant washable RFID -Tags (basierend auf dem NXP UCODE 9 Chip) for new products, with material data shared in the cloud.
- Sorting Line Upgrade: 4 sets of high-speed RFID tunnel machines were deployed, integrating RFID readers and RFID antennas.
- Sorting Execution: After reading the data, a PLC (Siemens S7-1500) controlled pneumatic pushers to guide the clothing into 12 different sorting channels.
3.3 Results Data (as of February 2026)
| Indikatoren | Vor der Implementierung (2024) | Nach der Implementierung (Q1 2026) | Improvement Scale |
| Daily Processing Capacity | 120 tons | 380 tons | ↑217% |
| Sorting Accuracy | 82% | 97.5% | ↑15.5% |
| Labor Cost | €4.2/ton | €1.1/ton | ↓74% |
| High-Value Recycling Rate | 18% | 31% | ↑72% |
| Annual Revenue Increase | – | €7.2 Million | New Revenue |
The CTO of CircleTex stated, “RFID transforms waste textiles from ‘garbage’ into assets carrying complete data. We can not only sort faster but also provide brand clients with recycling reports demonstrating the recycling rate of their products.”
Anpassungsmöglichkeiten: Addressing Complex Recycling Scenarios
The waste textile recycling scenario is far more complex than new product warehousing: clothing may be dirty, damp, oder beschädigt, and tags may be partially obscured. Genau hier liegen die Individualisierungsmöglichkeiten. RFIDHY provides:
4.1 Highly Robust Reading Algorithm
An adaptive power algorithm was developed to address the varying tag states in recycling scenarios, dynamically adjusting reader power and antenna selection to ensure maximum read rate.
4.2 Multi-Tag Collision Prevention Optimization
During dense stacking (such as bundled recycling), signal collisions between tags are severe. The RFID RecycleTunnel employs a hybrid time-division multiple access (TDMA) + frequency-division multiple access (FDMA) scheme, Verarbeitung 800+ tags simultaneously on a single channel.
4.3 Fragile Tag Design
For tags that need to be destroyed after recycling, RFIDHY EcoTag is provided. Made of biodegradable materials, it automatically deactivates after recycling and sorting, protecting consumer privacy.
4.4 Integration with NIR Systems
For existing clothing without RFID tags, the RFID sorting line can be linked with a near-infrared spectrometer (such as TOMRA AUTOSORT). RFID reading is the primary method, supplemented by NIR blind spot detection, achieving full coverage. Von 2026, waste textile recycling has shifted from a “arbeitsintensiv” zu einem “technology-intensive” model. Rfid, as a digital roadmap inherent in clothing, is reshaping every aspect of old clothing recycling: from source material recording to automated sorting in transit, and finally to end-user value assessment. Einen Partner auswählen (wie RFIDHY) that meets EPC Gen2v2 and ISO 18000-6C standards and possesses deep customization capabilities is a crucial step for recycling companies and brands to jointly build a closed-loop recycling system. Ja. Modern recycling and sorting lines typically use a hybrid model: RFID as the main channel, supplemented by near-infrared spectroscopy (NIR) or camera vision recognition. For untagged garments, NIR identifies the material before sorting, and biodegradable RFID tags can be attached after sorting for easy tracking. If the garments used washable tags that meet industrial-grade standards (Z.B., passing AARH Level 10 testing) during production, their lifespan can reach 10 years or 200 wäscht, fully covering the normal lifespan of the garment. The tags can still be read during recycling. Even ordinary hangtags may still be readable before disposal, but the readability will decrease. Commercial recycling lines typically require a conveyor belt speed of 2-3 Meter pro Sekunde, corresponding to processing 10,000-15,000 garments per hour. The RFID RecycleTunnel maintains a read rate of over 99.5% even at speeds of 3 Meter pro Sekunde, fully meeting the needs of large-scale recycling. This is precisely the core value of RFID in the circular economy. By recording information such as material composition and prohibited substance testing reports, RFID tags provide recyclers with reliable composition data, enabling high-value recycling (such as fiber-to-fiber). Brands can use this to obtain green certification and carbon reduction credits. The investment scale depends on the processing volume. For small recycling stations processing 5,000 tons annually, a desktop RFID sorting station (such as the RFIDHY SortDesk) can be selected, with an investment of approximately €20,000-30,000. Combined with handheld terminals, semi-automatic sorting can be achieved, Effizienzsteigerung durch 2-3 mal. Large recycling centers require a tunnel machine system costing €200,000-500,000.
