A new way to think about by-products

At Silhouette, we believe in transforming challenges into opportunities. With the Clear Sky Collection, we’ve embraced a groundbreaking approach to sustainability by turning organic by-products into high-performance eyewear. At the heart of this innovation is SPX^® Green+, a material that reflects our commitment to creating responsibly.

What is bio-circularity?

Bio-circularity is an advanced process that repurposes organic by-products—such as agricultural and forestry waste—into valuable materials. Unlike traditional recycling, bio-circularity enhances material quality while conserving resources and minimizing environmental impact. With this breakthrough in bio-circularity by-products become a resource, redefining the possibilities of sustainable design.

Crafted from organic by-products

The journey of SPX^® Green+ begins with sourcing organic by-products that would otherwise be discarded, using waste instead of new feedstock. This eliminates the need for additional cultivation areas, saving space and boosting biodiversity. These materials are then transformed through a process powered entirely by renewable energy, creating a polymer that is lightweight, durable, and completely fossil-free. This innovation reduces carbon emissions by 60% compared to conventional fossil-based materials, proving that performance and sustainability can go hand in hand.

A vision for responsible design

SPX^® Green+ is more than a material—it’s a statement of what’s possible when we rethink fossil-based production. The Clear Sky Collection shows how innovation can inspire responsibility, turning discarded by-products into eyewear that looks and feels extraordinary.
