**SMX and RedWave Complete Proof-of-Concept Trials, Successfully Demonstrating to NAFRA Certified Recycling with Digital Passport in Food-Grade, Flame-Retardant and Carbon Black Plastics**

**New York, 17 September 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 **RedWave**, demonstrating advanced sorting solutions for **NAFRA** (North American Flame Retardant Alliance).

The trials validated the commercial-speed identification and sorting of both **food-grade plastics** and **flame-retardant black plastics** with NAFRA.

**Industry Milestone Toward a Global Technological Development**

SMX believes that 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 RedWave's proprietary detection and sorting systems, the platform is being designed to deliver two outcomes:

&nbsp;&nbsp;&nbsp;&nbsp;1. Increasing
 the use of recycled content in new plastic applications.

2. Creating
 a full ecosystem through SMX's blockchain-backed digital passport, allowing for traceability from raw materials through production,
 recycling, and reuse.

Through SMX's blockchain-backed **digital passport**, this breakthrough potentially creates a **full digital platform ecosystem** for plastics — enabling traceability from raw materials through production, recycling, and reuse. This allows for every stage of the material lifecycle to be certified and trusted, laying the groundwork for recognized global standards in sustainable plastics.

The achievement by SMX, NAFRA, and RedWave is expected to be the first step in creating the foundation for an industry capability of marking and certifying tangible plastics.

By doing so, SMX believes that plastic waste can be transformed into a valuable commodity, because once it is marked and certified, it has the potential to be able to 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 a brominated flame retardant (DPDPE). The testing not only confirmed **commercial-speed detection and sorting performance** but also validated that the technology can **identify whether plastics contained a targeted composition of flame retardant** — across various types of plastics, including **carbon black plastics**. This breakthrough could help to ensure 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.

![](ex99-1_001.jpg)

SMX's molecular markers, integrated with RedWave's high-speed detection systems, bring new capabilities that are expected to unlock significant benefits:

● **Commercial Value:** High-purity food-grade plastics have been shown to be reliably separately identified from non-food plastics, which may help supply chains to 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 could help support manufacturers in meeting international safety and packaging regulations.

● **Sustainability:** By encouraging the recovery and reuse of more food-grade plastics, the process can help reduce dependence on virgin resins, directly lowering carbon emissions and resource demand.

● **Circular Economy Impact:** Clear certification of food-grade recyclates enables supply chain participants to re-enter packaging loops, rather than being downcycled or discarded, extending product lifecycles.

This innovation is designed to help ensure 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 large 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 generally left them excluded from advanced recycling systems.

SMX's molecular marking technology has been shown in the proof-of-concept trial to change this paradigm by enabling the real-time detection and separation of carbon black plastics.

This breakthrough has the potential to:

● Free 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.

● Reduce production costs by lowering the inflection point of pricing for new product lines, since automotive and electronic components would be manufactured with higher performance recycled black plastics instead of expensive rPET.

● Improve durability and quality of non-food-grade plastics: 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: helping to unlock recyclability for one of the hardest-to-recycle plastics while simultaneously to improve material allocation and cost-efficiency across industries (such as automotive, electronics and food products).

**Breakthrough in Sorting Plastics**

Using 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 could represent a significant breakthrough in recycling, as it not only could enable the recovery of food-grade plastics into compliant, closed-loop applications, but also could identify that plastics containing flame retardants meet the correct composition standards.

**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 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 RedWave, to establish recognized standards for circularity in plastics and expand adoption across various sectors.

By embedding certification into the value chain ecosystem, SMX believes its technology would ensure that plastics are no longer treated as waste but as a valuable, certifiable commodity, and that 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.
