Arkema announced it has partnered with the Zephir Project to develop a recyclable composite speed board using its Elium® thermoplastic resin.

The prototype, introduced at JEC World 2026, is designed to demonstrate how high-performance composite structures can incorporate circular design principles. The board uses recyclable materials, including Elium resin and recycled carbon fibers, to enable full chemical recycling through depolymerization.

According to the company, the liquid thermoplastic resin allows for the production of complex, high-precision parts while delivering performance comparable to traditional thermoset materials used in demanding applications.

The board will be used in upcoming windsurfing competitions and world record attempts, serving as a testing platform for materials under high-stress conditions.

Arkema said the project highlights the potential for recyclable composites to support both performance and sustainability goals, particularly in applications requiring strength, durability and precision.
