Patent Alert 2025-08

How can we truly tell recycled plastics apart from virgin materials? How can we measure the recycled content in products made from mixed sources, and ensure full traceability along the way? 

These questions are key to boosting the circular use of plastic waste. One promising solution lies in the use of markers—unique identifiers embedded in recycled plastics that enable traceability and verification of recycled content. This innovative approach is at the heart of this month’s spotlight.

1. Markers for recycled plastics
2. Recyclate verification
3. Method for producing a material with verifiable proportion of recycled material
4. Balancing of recyclable material amounts in product ecosystems
5. Recyclable racket sports ball and method of recycling a mixed waste stream comprising said ball
6. Silicon nanostructures as luminescent markers for the recycling of plastic
7. Recycling method and taggant for a recyclable product
8. Method and system for marking, tracking, grading and certifying plastics for enabling standardization and tokenization
