Recycled Polymer Tyre Microfibres

Sustainable Micro-Reinforcement from Recycled Tyre Polymers

Recycled Polymer Tyre Microfibres (RPTM) are innovative polymer-based fibres recovered from End-of-Life tyres, offering a sustainable alternative to conventional polypropylene fibres for concrete reinforcement.

These fine fibres enhance concrete performance in both fresh and hardened states, reducing plastic shrinkage cracking and mitigating explosive fire spalling — particularly in high-performance and ultra-high-performance concrete.

Sustainable Innovation

Each year, approximately 63,000 tonnes of polymer fibre are recovered from End-of-Life tyres, yet much of it is incinerated due to rubber contamination. RPTM transforms this underutilised material into a high-value construction product, reducing a very problematic waste, conserving resources and supporting a circular economy.

Key Benefits

• Mitigates explosive fire spalling in HPC and UHPC

• Reduces plastic shrinkage cracking

• Sustainable reuse of tyre-derived polymers

• Significantly lower environmental footprint than virgin polypropylene fibres

Applications

• Normal Concrete (NC)

• High-Performance Concrete (HPC)

• Ultra-High-Performance Concrete (UHPC)

• 3D-printed concrete and extrudable mixes

• Mortars, screeds, grouts and overlays

• Precast and architectural elements where finish and fire performance matter

Build Responsibly. Reinforce Sustainably.

RPTM combines innovation and sustainability, transforming recycled tyre polymers into high-performance micro-reinforcement for modern concrete solutions.
