Tandem Repeat teams up with Andritz to scale biofibre
Austrian textile machinery maker Andritz will be working with Tandem Repeat Technologies, a biotechnology company that is looking to scale up the production of Procell, a protein-based fibre for textiles and nonwovens. The wool-like softness, exceptional strength, durability and versatility of this new fibre make it well-suited for a broad range of applications. 

The partners intend to develop industrial-scale solutions for fibre manufacturers using Andritz equipment engineered to the specific requirements of Procell, while Tandem Repeat will partner on the development of Procell technology, the companies said. 

In other news, Tandem Repeat founder Melik Demirel co-authored an article published in the Proceedings of the National Academy of Sciences (PNAS), which focuses on the global impact of its patented technology compared to land usage dedicated to natural fibres. The report finds that scaling the biomanufacturing of Tandem's protein fibres could decouple textile production from agricultural land use.

Dr. Melik Demirel, co-founder of Tandem Repeat and Huck Endowed Chair Professor at Penn State, commented: “We are not just offering a green alternative; we are offering a mechanism to resolve the direct conflict between fashion and food security. Tandem’s platform is ready to deliver high-quality, high-volume fibre with a zero land footprint, representing the future of sustainable manufacturing.”
