cross almost every sector, design
engineers are being asked to reduce CO2 emissions and improve sustainability
credentials. This pressure is intensifying as governments introduce stricter environmental legislation and OEMs set ambitious net zero targets. Traditionally, attention has focused on major components and energy efficiency, but the scope has widened. Increasingly, engineers are looking at the life cycle analysis of components right down to the fasteners, which play a vital role in product integrity. At TR, part of the Trifast plc group, we see
first-hand how sustainability is driving new choices. Our customers want not only high- performance parts, but also clear evidence of environmental benefit. It’s no longer a ‘nice to
have’. It’s a business-critical requirement.
TR has a long-standing reputation for engineering innovation, and sustainability is now at the heart of our R&D programme. We began by exploring both recycled and bio-based plastics, conducting trials to evaluate their suitability for fastener applications. While biobased materials showed potential, it was the recycled grades that delivered the best balance of processability and mechanical performance. From the outset, our aim was simple – to
create a range of fasteners that maintain the robustness our customers expect, while significantly reducing environmental impact.

After extensive testing, recycled nylon emerged as the standout material.
The specific grade that performed best was a Nylon 6,6 derived from 100% recycled feedstock. At raw material level, this offered up to a 90%
reduction in CO2 emissions compared to virgin alternatives – a step change in sustainability. Crucially, this was not about compromise.
The recycled nylon maintained excellent processability and achieved mechanical properties at around 80% of prime-grade nylon. For the types of fasteners TR supplies, this performance sits well within safe working limits. Proven strength and lower emissions
