DyeRecycle is a fibre and innovation company pioneering chemical technology that prepares textile waste feedstock for high-quality recycling. Our process decontaminates waste fabrics, removes dyes, and separates cotton fibres, creating clean, white material ready for efficient fibre-to-fibre recycling. By reclaiming colours and liberating pure fibres, we reduce contamination risks and maximise recyclability without compromising performance or creativity.

Our vision is to unlock textile waste recycling at scale, enabling a future where planet-positive textiles are produced through circular processes and transparent supply chains.

Our mission is to scale our innovation and integrate it seamlessly into the global textile supply chain, providing real and simple solutions to reduce the industry’s dependence on virgin material
