The textile world is on the brink of a transformation — and the alliance between Andritz and Tandem Repeat is leading the way. Together, these two powerhouses have embarked on a mission to commercialize Procell, a protein-based sustainable fiber designed to mimic the softness and strength of wool while offering eco-conscious performance.

This collaboration combines Andritz’s advanced engineering and nonwoven manufacturing expertise with Tandem Repeat’s cutting-edge biotechnology innovation. The result? A breakthrough in the production of sustainable fibers that are strong, soft, and suitable for a wide range of textile and nonwoven applications.

Procell is not just another green product — it represents a shift towards biomanufactured fibers that merge science and sustainability. Developed and patented by Tandem Repeat, Procell uses protein structures similar to those found in nature, creating a material that’s biodegradable yet durable.

According to Dr. Sergey Malkov, VP of Manmade Cellulosic Fibers at Andritz, “Procell fiber has the potential to be a true breakthrough in sustainable materials.” This statement echoes the growing urgency within the fashion and textile industries to move away from synthetic fibers and toward renewable, circular alternatives.

Dr. Melik Demirel, co-founder of Tandem Repeat, also highlighted the impact of this partnership: “By partnering with Andritz, we can bring our revolutionary fiber to market on a commercial scale. This will support industries in achieving sustainable production and supply chain resilience.”

Together, Andritz and Tandem Repeat aim to offer scalable industrial solutions that empower fiber manufacturers to adopt Procell technology across global markets. As environmental awareness and regulatory pressures intensify, innovations like Procell could become the backbone of next-generation textiles.

Conclusion

The partnership between Andritz and Tandem Repeat signifies more than just a technological alliance — it’s a bold step toward a sustainable future for textiles. By combining biotechnology and industrial engineering, they’re setting a new benchmark for eco-friendly materials that don’t compromise performance. As global industries seek greener alternatives, Procell could emerge as a pivotal solution, leading the charge toward a circular, responsible fashion ecosystem.
