Shares of SMX (Security Matters) Public Limited Company closed at $9.64, gaining 0.73%, as the company extended its plastic verification technology into new verified markets, according to Blockonomi. The company is developing a system that links physical materials with digital records through its Digital Material Passport platform. The move introduces new applications across verified material markets, recycling systems, and circular economy infrastructure.

The development lands amid mounting scrutiny of recycled-content claims from regulators and corporate buyers, an environment that has put material-level verification technology in focus across the plastics supply chain.

Digital Material Passport Platform Expands

SMX has expanded its technology beyond plastic authentication into broader material tracking solutions. The platform connects physical plastic materials with digital records that store verified lifecycle information, creating a link between production, reuse, and material verification processes.

At the core of the system is molecular marking technology, which identifies plastic materials throughout their lifecycle. The markers allow companies to confirm material identity without relying solely on external documents. As a result, manufacturers can build stronger records for recycled content and for their supply chains.

The Digital Material Passport platform adds digital information to physically marked materials, recording details such as origin, composition, custody history, and lifecycle status. The platform also supports enterprise systems through data tools and integration features. The passport concept reflects a broader policy direction in Europe, where digital product passports are being introduced to document material composition and sustainability data along supply chains.

SMX Targets Verified Material Markets

SMX designed its platform to connect physical materials with digital markets and asset applications. Verified material information moves through blockchain-based records, allowing companies to apply authenticated data across different commercial processes.

The platform follows a structure that progresses from material identification to market participation, connecting material marking, digital passports, blockchain records, and circularity credits. This approach creates a continuous record of verified material movement.

SMX is also building a client experience that allows companies to test the technology on their own plastic materials. Businesses can submit materials for marking, identification, and digital passport creation, demonstrating how the system operates across different industrial applications.

Building Circular Economy Infrastructure

SMX is positioning its technology within growing demand for recycled material verification. The company links recycling activity with measurable data and documented lifecycle records, supporting businesses that seek clearer information about recovered materials.

The company's Circularity-as-a-Service model focuses on documenting plastic recovery and reuse. Verified recycling events can support the creation of Plastic Circularity Credits, which represent documented circular activity connected to authenticated materials.

The platform combines physical verification with digital infrastructure for material management. A manufacturer can mark plastic during production and track it through later reuse cycles, while recyclers and brands can access verified information during material transitions.

The technology addresses challenges within the recycled plastics sector, where market participants increasingly require reliable proof of recycled content and material origin. Much of the sector still relies on paperwork-based certification, an approach that has drawn scrutiny as brands and regulators press for substantiated environmental claims. Regulatory requirements are also tightening: the European Union's packaging rules set minimum recycled content levels for plastic packaging that phase in from 2030, raising the need for traceable, verifiable material data. SMX aims to provide a system that connects this information across the material lifecycle.

By pairing molecular markers with digital passports and blockchain-based records, the company is working to give recycling systems and circular economy programs a continuous, verifiable data trail from production through reuse. How SMX's client testing experience performs across industrial applications, and how its Plastic Circularity Credits are received in material markets, will offer further indication of the platform's role in that infrastructure.
