Want a Sustainable Alternative to Plastics?

"The ability to simplify means to eliminate the unnecessary so that the necessary may speak.”

-Hans Hofmann, Artist / Painter

For nearly three decades, ISA TanTec has revolutionized the footwear leather industry by crafting the best quality leather while moving sustainable practices to the forefront of our manufacturing processes. Being leaders in leather tanning wasn’t good enough for us. We recognized a need to complement our leathers with sustainable alternatives to petro-based synthetics and textiles, and tackle a long-standing environmental concern within our industry: plastic and global plastic pollutions.


We are proud to introduce HyphaLite TC. A breakthrough innovation in biobased footwear and accessory materials. HyphaLite TC is the first material developed by our COSM division. Inspired by nature, HyphaLite TC is our solution to petro-based synthetics. It is 100% biobased, biodegradable and regenerative. We developed HyphaLite TC to achieve the highest level of bio content without compromising performance.


“The most sustainable way is to not make things. The second most sustainable way is to make things very useful, to solve a problem that hasn't been solved.”


-Thomas Sigsgaard, Architect / Designer

Executive Chairman

We want to enter the plant-based material market and replace plastics which are falsely called sustainable. So we developed HyphaLite™ TC.

The Genesis of HyphaLite™

Elephant in the Room

The so-called “vegan leather”, which is oxymoronic in itself, has increased in popularity. Many of those products are advertised as environmentally friendly. However, these contain plastics, one of the biggest threats to our ecosystem.

Uwe Hutzler

Chief Executive Officer

That’s why we started COSM™, so we could offer products additional to leather, to give our customers the option to design other materials into their shoes, by sourcing from us as the same supplier.

Always ahead of the curve, our family of Hypha-materials rises to the standards of footwear performance and are fully available in production.

Reiner Hengstmann

VP Additional Materials

HyphaLite™ TC, as the first material developed by COSM™, should not be seen as an alternative to the already sustainably produced leather at ISA TanTec following the LITE values for manufacturing, but as an excellent addition to leather as it meets standards and KPIs for footwear and accessories. Following the COSM™ philosophy, the HyphaLite™ TC material is just the start for ISA TanTec of an exciting journey towards new and additional materials.
