SMX and BT-Systems - Competence Center REDWAVE Demonstrate to NAFRA Breakthrough Toward Industry Standard for Certified Recycling with Digital Passport in Food-Grade, Flame-Retardant and Carbon Black Plastics
NEW YORK, NY / ACCESS Newswire / September 17, 2025 / SMX (Security Matters) PLC (NASDAQ:SMX, SMXWW)), a global pioneer in digitizing physical objects for a circular economy, today announced the successful completion of two proof-of-concept trials, conducted over two consecutive days, with its service provider BT-Systems - Competence Center REDWAVE, demonstrating advanced sorting solutions for NAFRA (National Flame Retardant Association).
The trials validated the high-speed identification and sorting of both food-grade plastics and flame-retardant black plastics with NAFRA.
Industry Milestone Toward a Global Standard
These trials represent a critical step toward establishing an industry standard for plastic traceability and recycling. By embedding SMX's molecular markers into materials and pairing them with BT-Systems - Competence Center REDWAVE's proprietary detection and sorting systems, the platform delivers two powerful outcomes:
Increasing the use of recycled content in new plastic applications.
Creating a full ecosystem through SMX's blockchain-backed digital passport, ensuring traceability from raw materials through production, recycling, and reuse.
Through SMX's blockchain-backed digital passport, this breakthrough creates a full digital platform ecosystem for plastics - enabling traceability from raw materials through production, recycling, and reuse. This ensures that every stage of the material lifecycle can be certified and trusted, laying the groundwork for recognized global standards in sustainable plastics.
The breakthrough achieved by SMX, NAFRA, and BT-Systems - Competence Center REDWAVE is not only about sorting. Sorting is the technical activity - the true innovation lies in creating the foundation for an industry standard of marking and certifying tangible plastics.
By doing so, plastic waste is transformed into a valuable commodity, because once it is marked and certified, it can re-enter supply chains with trusted quality and compliance - driving both commercial value and circular economic impact.
Two-Day Showcase Demonstration: Food-Grade, Flame-Retardant and Carbon Black Plastics
Day 1 -Trials focused on food-grade plastics. This collaboration aims to accelerate the adoption of advanced recycling technologies in support of Singapore's circular economy targets.
Day 2 - NAFRA Collaboration: NAFRA, the National Flame Retardant Association, partnered with SMX to test plastics containing brominated flame retardants (DPDPE*). The objective was not only to confirm high-speed detection and sorting performance but also to validate that the technology can identify whether plastics contained the correct composition of flame retardant - across all types of plastics, including carbon black plastics. This breakthrough ensures both compliance with safety standards and the potential for closed-loop recycling of complex materials.
Importance of Sorting Food-Grade Plastics
As part of SMX's collaboration, the trials highlighted the importance of improving food-grade plastic recycling. Food-grade plastics are vital to consumer safety and regulatory compliance, yet their recyclability has been limited by inconsistent separation at scale.
SMX's molecular markers, integrated with RedWave's high-speed detection systems, bring new capabilities that unlock significant benefits:
Commercial Value: High-purity food-grade plastics can now be reliably separated from non-food plastics, ensuring supply chains have secure, lower-cost access to recycled content that meets stringent food-contact standards.
Regulatory Compliance: The ability to verify food-grade quality in real time supports manufacturers in meeting international safety and packaging regulations.
Sustainability: By recovering and reusing more food-grade plastics, the process reduces dependence on virgin resins, directly lowering carbon emissions and resource demand.
Circular Economy Impact: Clear certification of food-grade recyclates enables them to re-enter packaging loops, rather than being downcycled or discarded, extending product lifecycles.
This innovation ensures that food packaging producers and brand owners can confidently source sustainable, compliant recycled plastics - turning waste into high-value raw material.
Why Carbon Black Plastics Matter
Carbon black plastic is a widely used material, produced by infusing plastics with carbon black pigment. It plays a critical role in electronics and automotive manufacturing - industries where durability, color, UV resistance, strength, electrical conductivity and safety requirements are paramount.
Until now, carbon black plastics have been virtually impossible to sort and certify for recycling, because their dark pigmentation absorbs infrared, laser, and imaging signals used by conventional sorting technologies. This has left them excluded from advanced recycling systems.
SMX's molecular marking technology changes this paradigm by enabling the real-time detection and separation of carbon black plastics.
This breakthrough:
Frees food-grade rPET plastics (recycled PET bottles) from being diverted into non-food applications such as dashboards, car seats, and electronic housings - where they are not technically optimal.
Reduces production costs by lowering the inflection point of pricing for new product lines, since automotive and electronic components can now be manufactured with higher performance recycled black plastics instead of expensive rPET.
Improves durability and quality: Food-grade rPET is designed for short-term use (holding liquids for just a few months), whereas automotive and electronics demand plastics that last for years or even decades.
This creates a double benefit: unlocking recyclability for one of the hardest-to-recycle plastics while simultaneously improving material allocation and cost-efficiency across industries (such as automotive, electronics and food products).
Breakthrough in Sorting Plastics
Using BT-Systems - Competence Center REDWAVE's industrial sorting system, operating at 2 m/s conveyor speed, SMX-marked plastics - including food-grade materials, fire-retardant compositions, and carbon black plastics - were consistently detected and separated with 99-100% accuracy.
This represents a significant breakthrough in recycling, as it not only enables the recovery of food-grade plastics into compliant, closed-loop applications, but also ensures identification of plastics containing flame retardants meet the correct composition standards. Importantly, it also unlocks the recyclability of carbon black plastics, which have traditionally been among the most difficult to identify and recover due to their light-absorbing properties.
Pilot Highlights
Trials Conducted: Two-day program covering food-grade plastics and flame-retardant black plastics (NAFRA).
Throughput: 2 m/s conveyor line speed.
Material Processed: 22 kg across six design runs and one combined scale-up run.
Technology: SMX molecular marker embedded in plastics, tracked via BT-Systems - Competence Center REDWAVE, SMX's service provider for detection and sorting.
Performance Results
Recognition: Consistent identification of SMX-marked plastics across all compositions.
Accuracy: 99-100% detection and separation.
Stability: High-speed classification maintained at industrial throughput.
Next Steps
SMX is now assessing commercial roll-out opportunities with its service provider BT-Systems - Competence Center REDWAVE, for NAFRA, to establish recognized standards for circularity in plastics and expand adoption across various sectors.
By embedding certification into the value chain ecosystem, SMX's technology ensures that plastics are no longer treated as waste but as a valuable, certifiable commodity. Once marked and certified, plastics can re-enter supply chains with trusted quality, creating new commercial opportunities while driving global progress toward a circular economy.
