Smarter. Greener. Lighter. The new generation of recyclable composites

Across the industry, a new generation of hybrid materials and media surfaces is taking shape. This article explores technologies that lead the way and how Antalis is helping turn innovation into real-world action.

Composite materials: 3 that are now recyclable

Light and strong, composite materials have long offered a technical edge. But they have a notable drawback: their low recyclability. Most of them rely on petrochemical resins or complex adhesives, which makes them hard to break down and reuse.

Now, that’s changing. A new avenue is opening up with new-generation composite materials that are recyclable. Let’s explore 3 of those materials that open new circularity models. 

Epoxy resins are strong and versatile. The downside is they’re almost impossible to recycle due to their rigid 3D structure. Most of them are composed of bisphenol A, a toxic chemical.

Until now, there was no clean solution. But a French research team has just developed an epoxy resin based on lignin derivatives that is 90% recyclable and free from bisphenol A.

This discovery opens the door to composite materials that are both high-performance and circular: ideal for cutting waste without sacrificing strength.

PP-based composites offer a rare balance of strength, lightness, and recyclability. By combining polypropylene with reinforcing fibres or nanoparticles, these materials deliver the rigidity of a composite without sacrificing end-of-life recovery.

Unlike thermoset resins, PP can be melted and reused, making these composites compatible with circular manufacturing models. They're ideal for signage, automotive parts, or retail displays where weight and durability matter.

Some new materials go even further. Made with natural fibres like flax or hemp, they reduce carbon emissions at the source. Their structure is both strong and bio-based, and some can even return to the soil after use. The idea of signage that once grew in a field is no longer science fiction.

Notice that these materials are not alternatives; they’re upgrades. In a world where every square metre counts, hybrid materials offer a way to think smarter about both the message and the medium.

Greener ads or when the medium becomes the message

Sustainable signage doesn’t stop at the material. Today, the structure itself can carry meaning. We’re entering an era where display formats are no longer passive surfaces. They interact with the environment, adding value beyond visibility.

Solar-powered digital signage is moving from prototype to reality, offering a clean alternative for high-impact outdoor communication.

In South Africa, the media company Epic Outdoor has launched a gigantic digital billboard powered almost entirely by photovoltaic solar energy.

When powered by clean energy, a screen becomes more than a tool; it becomes part of the solution.

Smaller, portable units are also emerging, like 43" freestanding screens made by the company Displays2go. They operate off-grid for up to 12 hours and offer eco-friendly, cost-saving communication.

Reducing energy use at the hardware level starts with the right materials and better design. LG’s high-brightness outdoor screens are built with smart light sensors to adjust brightness in real-time. It ensures visibility without wasting power.

Meanwhile, GORE’s natural air-cooling technology takes a different approach: it uses passive airflow to regulate internal temperature, eliminating the need for energy-hungry fans.

Both innovations point in the same direction: signage systems that consume less, run longer, and align with the environmental expectations of today’s public spaces.

Vegetation is making its way into the media. Green advertising is no longer just about energy-efficient screens or recyclable posters. It’s about rethinking the display itself.

In German cities like Düsseldorf and Berlin, a new format is emerging: digital screens integrated into living plant walls. These hybrid installations combine high-impact messaging with real environmental benefits.

And the results are measurable: thousands of plants surrounding each screen help absorb CO₂, produce oxygen, and even cool the surrounding air. One installation in Düsseldorf captures over 400 kg of CO₂ per year while releasing more than 300 kg of oxygen.

This new hybrid signage doesn’t just inform or promote. In our crowded cities, it invites us to pause and reconnect to our deep nature.

Conclusion: Smarter materials send a strong message
